Features & Specifications

Rated at 40 Watts per channel RMS at 8 ohms, the MX1260 is a serious contender for complex audio systems and will distribute sound to 12 different locations without the risk of overload. Equipped with brains and brawn, this sturdy, rack-mountable high current amp includes 6 zones or 12 channels (speakers), so owning this amp is like having six 2-channel amps in one efficient location.

What is a Multi-Channel Amplifier? Multi-channel amps incorporate high-efficiency, space-saving digital technology. Multi-channel amps eliminate the complexity of wiring up multiple two-channel amps, save space by reducing the number of components that must be placed in cabinets, and drive down your amplifier costs by as much as a third over multiple two-channel models, or adding impedance matching equipment to the two channel systems. Having a 12 or 16 channel amplifier will allow you to directly connect 12 or 16 rooms, directly to the amplifier without overloading.

from Ottawa, CN asked:

Hi there, How does the auto-on feature work for the mx1260? Any pre-amp signal on any input channel greater than a threshold turns it on? And to turn off?
1 Answers
HI Joel: The Auto on sensing switch turns each zone on depending on how it is connected. There are three options per each channel, Line in, Bus 1 or Bus 2. When you activate the auto sensing (making sure you have the power button on the front panel pushed in) each zone (made up of 2 channels) will start out in standby mode with the status LED showing red at first, Then once it senses the signal it turns blue and becomes active and starts playing almost immediately after sensing the signal. Once the signal is no longer present on that zone after 5 minutes it goes it sleep mode with the LED turning to red. With the Buss system you can have multiple zones connected. You could have zone 1, 2 and 3 connected to Bus 1 and as long as the signal is present all three LED's would light up blue. Once you turn off that signal roughly after 5 minutes all three of the zones would go into Sleep or standby mode and the three LED's would turn red. I believe if you do not use the Auto sensing mode, choosing to select "On" then the AMP and its zones will not go into stand by or sleep mode. So each zone or zone grouping when in the auto sensing will feature the stand by mode (sleep mode) whether the input is set to Line in, Bus 1 or Bus 2 setting. Sorry, the Owner's manual may be a little confusing. TL/4417

from Virginia asked:
May 16, 2017
HI, How does everyone set the volume in the back? Do you turn them all the way up and then control at the wall volume switches or will that create distortion? Is it better to have them 1/2 to 3/4 of the way and then work the higher side of the wall volume controls? Thanks for any input.
1 Answers
Hi Bill: You typically set your source volume to about three quarters. Set your volume controls to full open all the way clockwise. Now adjust the Gain control (you label as Volume Control) adjusting the knob until you hear the signal distorting. Back the gain back just below the distortion point. Now you leave your gain controls alone and control your volume levels with either your source control. You will know if you need to back that down if it starts to distort. Or at the Volume Control which does not add any gain but is an attenuator where you are just turning the volume down by diverting the signal into the transformers which are part of the Volume Control. Eventually you will turn the knob down where the signal is inaudible. You can not turn off the individual zones with Volume Control. You can put the amplifier in standby mode if your turn on option is set to Auto sensing. TL/4367

from Georgia asked:

I currently have this amp with impedance matching volume controls and it works great. I am currently using 1 source only for the whole house. My question is, if I go to more sources, will this AMP allow 1 source to multiple zones? For example, I have 6 zones but 4 sources, can 1 of the sources work 2 zones and the other 4 sources work 1 zone each? I am using with Sonos and it works great. Thanks for supplying a great product!
1 Answers
Hi Richard: The MX-1260 is very flexible especially since it has three input options for each zone. Currently you have the SONOS connected to the BUS 1 input. You could add a second SONOS to connect to BUS 2. So zones 1-4, the input switch would be set to BUS 1 and then zones 5 and 6 could be set to BUS 2. That way depending on how you grouped your zones you could have a dedicated SONOS for that group of Zones. As an example let's say zone 1 is the kitchen, zone 2 is the family room off the kitchen, zone 3 the Dinning room off the kitchen and zone 4 might be the deck off the family room. Then say zone 5 is the Master Bedroom and the Master Bath might be zone 6. So each SONOS would control a group. Down the road you could add a third SONOS for your zone 4 (outside) connecting it directly to the Zone 4 input and changing the input switch for left and right to Line in. Note your Impedance Matching Volume Controls settings for your six zones should all be set to 1X or 1/2X depending on the Volume Controls you have. There is really no need for impedance matching unless you are connecting more than two pairs of speakers to any of your six zones. Now in regard to your specific application four sources powering 6 zones. You can connect one SONOS to BUS 1 and connect to Zone 1 and 2 (channels 1-4). Number two SONOS connect to BUS 2 and power Zone 3-4 (channels 5-8). Then SONOS number 3 to connect directly to channel 9 and 10; Zone 3 and SONOS number 4 to Channels 11-12; Zone 6. For both Zone 5 and Zone 6 set source input to Line In. TL/4250

from Toronto asked:
October 17, 2016
I plan to bride this amp to power 3 zones (2 speakers per zone). Each zone will have a dedicated sonos connect. That way I can control what music is played in each zone as well as the volume in each zone via the sonos app. Can this be done?
1 Answers
Hi Tom: I believe so. You would bridge channel 1 and 2 for the left speaker and channels 3 and 4 bridged for the right channel both for Zone 1 and SONOS Connect #1. Channels 5-8 for Zone 2 /SONOS Connect #2 and Channels 9-12 for Zone 3/SONOS Connect #3. Now that is if you are driving a pair of 8 ohm speakers for each zone. You have some flexibility if you need to drive two pair of speakers in any one of your three zones. If this were the case you would not bridge four of the channels but assign channel 1 and 2 as left and right and channel 3 and 4 as left and right as well, You would take the SONOS Connect and wire it to the BUS 1 input and then assign the input for each channel to BUS1. You have some flexibility Good luck TL/4096

anthony
from san diego asked:
May 3, 2017
how would you control the volume on each of these zones?
1 Answers
Hi Anthony: There is a gain control for each channel but that is a set it and forget adjustment. Typically you will control the volume with by the source you have connected to each channel. But you can also add Volume Controls for each channel as well so you can control the volume from the zone. The Volume Control you can add is an attenuate which means you are actually turning the volume down from whatever setting from the source. You also have two universal bus inputs that allows you to have one or two sources powering all 12 channels. You could run a SONOS Connect as a source to Bus #1 and have it play on all six zones and your smartphone with the app would control the Volume and bass and treble. TL/4345

Can an Amazon DOT be connected directly to the MX1260 and have it play music sourced from the DOT without using a receiver? If so can the DOT be used to trigger the AMP on? Similarly can i connect a CD player as well?
1 Answers
Hi Mike: The AMAZON DOT can be connected to the MX-1260 through the Universal Buss using a 3.5mm to dual RCA adaptor cable. The key is you have a volume control (+/-) on the DOT. Plus you can set your turn on to Auto sensing on the MX-1260 so when you activate the DOT the MX-1260 will sense the signal and will turn on. A CD player can be added but you would have to find a player with a volume control built in. You could add our Pre1 pre-amp to control your different sources. TL/4165

Can I use the bus selector AND the direct input to each channel, or am I stuck BUS SELECTOR ONLY or DIRECT INPUT ONLY? Thanks for all the great info here...
1 Answers
Hi RH: You have a choice for each channel where you can select Bus 1, Bus 2 or Line input. But you can do that in any combination you choose.You could select Bus 1 for Channels 1, 2, 3, 4 and line in for channels 5, 6, 7, 8 and then back to Bus 1 for channel 9, 10, 11 and 12. You have to select one of the three options and of course a low level input has to be connected to the corresponding input as well. Note when you select the turn on option it affects all 12 channels or 6 zones, Manual on, switched with power button on the front. Auto Sensing also needs to have the power button pushed in (on position) to work, but goes into stand by when no signal present. The Power button must be on as well for the trigger to receive a signal to turn on. I am not sure if that totally answered your question, let me know how your question pertains to your application.; tim@osdaudio.com TL/3859

Jesse
from Texas asked:
April 25, 2016
Will the MX1260 allow different inputs to play simultaneously thru the zone they are connected to? For example, if I'm listening to music on my patio via input 1 - zone 1, can my kids listen to music in the living room via input 2 - zone 2 at the same time? If so does that apply to each of the 6 inputs and their corresponding zone?
1 Answers
HI Jesse: Yes, you can play different sources thru different zones. Technically you can connect up to six stereo inputs or a combination using the two universal buss inputs or direct input to the zone. You have a line input switch for each channel. So zone one has a switch for left channel 1 input and right channel 2 input. There are three settings for each channel; Buss 1, Buss 2 or Line in (local direct input). The Buss 1 and 2 settings are a universal input that can be selected for 1 to 6 zones. The local input is only for that channel/zone. So yes this will work for your application but the these switches are located on the rear panel and depending on your installation may not be readily accessible to change. I hope that answers your question. TL/3842

March 15, 2016
I am interested the in the MX1260 amp. I have 2 outdoor speakers and 4 indoor in-ceiling speakers. What i would like to do is connect a SONOS:CONNECT to each zone. One for outdoor and one for indoor (total of 2) so i can independently listen to different sources at the same time or listen to the same music all at one time across the 2 zones. Is this possible with this amp? I am somewhat confused with other amps indicating that I can only have one source playing across both zones simultaneously and not play different sources at the same time across both zones.
1 Answers
Hi David: I will answer your question comparing the MX-1260 to the AMP300 in the second email. The key is the dual SONOS Connects... A couple of quick questions so I can fully answer your application. 1) Outdoor zone, how big an area are you covering, will the AP650, will they be 10 to 12 feet apart? Can you add a Volume control in line either outdoors or inside near the door heading to the outside zone (inside would be best)? 2) Are both the MK-650 in-ceiling pairs in the same room. Do you have a place to add a volume control either to control both speakers or two volume controls, one for each pair of speakers. 3) I am definitely leaning towards the MX-1260 for your application due to its flexibility. Any room or thoughts about expanding further? I will wait for your responses to the above questions before I answer your second question regarding the AMP300. TL/3758

I have a house with six zones and two speakers in each zone. Each room has it's own volume control knob as well. Is this the amp I need to power these speakers in all six zones (12 total speakers)? Also, I'm guessing I would need a Sonos amp or connect to stream music through this to all the speakers? Right now all the wiring from the speakers just runs down to one cabinet in the basement but there is no receiver or anything there. It's just an empty box with all the wiring run to it.

1 Answers
Hi Whatley: Questions, What is the current Speaker Selector that you are using (upgrading)? What model ONKYO are you using, does it come with a control Application that you can download to control the basic functions of the AV Receiver? You are having no problems with your current setup (the speaker selector connected to the four pair of speakers)? Note: Most AV Receiver manufacturers recommend going to a external Amplifier when attempting to power multiple speakers on the single Zone 2 output. Even if you went to the SSVC4 as an upgrade we would recommend going to our AMP200 to have the dire ct pre-amp output of the ONKYO. Something we will know if a pre-amp output is available on your Receiver once we know the model number. When you add an SSVC4 with four internal Impedance Matching Volume controls you are adding an additional load to the output more so than the standard speaker selector used previously. And you will still only be able to control the SONOS for the single common output with no control over the mechanical volume controls of the SSVC4. I am not sure we can solve all your questions until you answer our additional questions. But it is a good starting point. TS-2285

Hi Sunday: Question #1, yes if they are six stereo pairs or a combination of single stereo speakers with DVC's (Dual Voice Coils). Question #2) the volume controls are connected between the speaker and speaker selector. The Volume Controls are stereo as well with right and left inputs (+/-). It is recommended using a Volume Control (Impedance Matching VC) for each zone you connect. Then make sure protection switch on the ISS8 is disabled (turned off). If you have 6 stereo pairs connected to six impedance matching Volume controls you will set the switch on the volume controls to 8X. Question #3) Different applications, the MX-1260 is a pure 12 channel six stereo Power Amplifier. The NUVO Essential is a complete control system with the same amount of channels but is also features a pre-amp controlling six zones and includes Key Pads one for each of those zones with two way communication between the Control Amp and key pads.

1 Answers
Hi Setiawan, We recommend you change the fuse to the value for 230 Volt, T5AL. Then you will need to make sure you set the voltage switch to 230V. You then can eliminate your up converter and use an adopter plug to connect to your wall outlet. It will also try to duplicate the LED staying on once you disconnect. You may experience a slight burn in smell when an amp is first turned on. If it escalates or continues, you may have a problem. Normally, we would not suggest removing the cover but due to the distance and the fact you may have found the problem that is good news.

1 Answers
Hi Setiawan, The MX1260 amplifier is setup for multiple voltages. However, you need to set the voltage switch to 230V and change the fuse to T5AL versus the T10AL. You may have blown the fuse. Remove the fuse in the unit and replace with the proper fuse. It will be same style but half the value. Then you can use an adapter plug to connect to the local input plug in Indonesia (either a C-, F- or G-type). The adapter does not do the conversion; that is done internally by the amplifier.

I apologize for not being more specific in my question. Currently all the speaker wires from all the different rooms in the house come out in 1 section of my wall. I have them all pigtailed into the back of a Onkyo AV Receiver TX-NR609. Now in each room I have a volume control knob by Niles. Nothing fancy just one that turns the volume up and down, no keypad. I am looking at the Sonos system to be able to control each room from where ever I am at and to be able to have different music if I want in rooms. The walls also have Cat-5 wires in them but I am currently not using those. You mentioned that I would need a local amp like your AMP200 to actually supply the power for each connect I add. I was wondering what sort of Amp would give me plenty of power to supply a system like this for say 8 rooms (2 speakers each) and a bath with 1 dual speaker. Do I need to buy multiple Amps or can I get away with just getting 1 amp for the 4 and half rooms. Once again I appreciate all your help on this issue. Dan
1 Answers
Hi Daniel: I understand you have your whole house audio system connected to your Onkyo AV receiver. Are you connected to Room 2 output of the Receiver? Are you using the Receiver for a 5.1 surround Sound System and using the Speaker Level outputs for the second zone? Are you presently using a Speaker Selector or just using the Niles Impedance Matching Volume Controls to protect the Receiver from seeing a 4 ohm or less? Do you have your Receiver connected to the internet or tied in with a computer Library as a source? I might suggest adding at least an external Amplifier like our AMP200 and DSM4 to run your current system. Use the Speaker A to power the DSM and Kitchen/family room, Master bedroom and also the Bathroom (if I remember correctly) speakers and use Speaker B to run the Outdoor setup. Use the SONOS Connect for your source (either to your AVR or as a second input for your AMP200) and then plan to add SONOS stations to each additional rooms you want to add sound to (you mentioned the possibility of 8 rooms). Then you can add their all in one speaker/network system instantly to each room as your budget allows. It is just plug and play once you add the SONOS to a room. You do have the option of going with their Zone amplifier in a room where you might want to add your own speakers. You just have to run wires from the amp to the speakers. This will allow you to upgrade your current Whole House Audio while planning to go wireless network as you expand. Let me know if that helps.

Would something like this workout for what I am doing? Thanks for all your assistance.

The idea of going with a SONOS wireless system is to be able to setup a network in the home that will give you great access to a multitude of source material while allowing you to control your system with either your Android device, iPhone, iPad or a SONOS remote. It sounds like you are trying to utilize your existing whole house wired system where your wiring must be home run to a central location. We would need to know what you currently have as a system and how and where it is wired to your speakers. The reason I ask is when I think of the SONOS system I envision placing a SONOS Connect (formerly ZONE Player 90) for each of your current zone locations: perhaps one for your outdoor speakers, one for your kitchen living room area and maybe a third unit to control your bedroom and single stereo speaker in the bathroom. However, you would need a local amp like our AMP200 to actually supply the power for each “Connect” you add. The other alternative is to buy SONOS Connect AMP but I believe that in both cases, you’ll want to access your wiring for each zone or zone grouping. Allowing us to help you out on this helps us understand how our components can interface with the very popular SONOS system. We are here to help. TL/MA question 1238

How are bridgeable output used or why do I need them?
2 Answers
Hi Joe, Bridging the MX1260's outputs gives you a mono signal but higher power output. So for each channel you would only use the inside right and left outputs, one positive and one negative. CL
Customer Service - Q&A
on July 27, 2012
Hi Joe: When you are bridging you are tying two channels together thus doubling the power. So Zone one (channels 1 and 2) become a single channel 40 x 2 or 80 watts. You would then connect left channel input associated with Channel one. Next you would bridge Zone 2 (channels 3 & 4) then connect the right input associated with channel 4. Essentially you have doubled the output power. The amplifier can go from 12 channels at 40 watts per, to 6 stereo zones at 40 watts per channel to 3 Zones at 80 watts per channel. It provides maximum flexibility no matter what your application. TL

July 25, 2012
OK TL; Since you are recommending the AMP300 & the SSVC6, should I operate the amp in stereo or bridge mode to get the largest sound from the following speaker setup around my pool & patio areas? Zone 1-5: (10) AP650 Speakers [(2) Lt Pool, (2) Rt Pool, (2) Patio, (2) Bar, (2) Jacuzzi] Zone 6: (2) SUB200 Speakers OR Is this too much of a load for the AMP300 by itself with the SUB200s and I should add a second amp for just the SUB200s and use the Dual Source version of the SSVC6? Please advise.
1 Answers
Hi Troy: Where are you planning to install the AMP300, the speaker selector and the Source Components? The AMP300 is plenty for whatever you throw at it. Just assume you are planning to have the control center at the bar. You obviously have the location figured for the AP650 indoor/outdoor speakers. But where are the RSUB200 going to be placed. Lets say you plan to interface the sub 200 with the speakers located around the pool. So what you do is run four conductors from the speaker selector on the right and left zone of the pool directly to its own RSUB200 (one for the Rt and another for the Lt) . From there you would connect a pair of the AP650 directly from the sub. One Pair AP650 and SUB200 for the Lt Pool and another pair of AP650 and a SUB200 for the Rt Pool location. That leaves a pair of AP for your Patio, Bar and Jacuzzi. I would suggest purchasing an SSVC4 Speaker Selector (versus SSVC6) and using it to control Zone 1, LT Pool (Sub200 to pair AP650), Zone 2, Rt Pool (Sub200 to AP650 Pair), Zone 3 for the Patio pair of AP650 (directly from Selector) and Zone 4 goes to the Bar pair of AP650. So we have two sub Sat zones around the pool. a pair of speakers on the patio and the fourth pair at the Bar where you have control with the Speaker selectors and its four independent Volume Controls and On/Off switch per zone. The SSVC4 has internal jumper settings for the impedance matching giving you a little more flexibility over the SSVC6. So now for the jacuzzi. Here you will want to connect directly from the Speaker B output of the AMP300 (The SSVC4 will connect to Speaker A). I would recommend adding one of our OVC300 Outdoor volume Controls plus a possible third RSub200 to wire in line with the fifth and last pair of AP650 speakers. Ideally you would want to place the Volume Control close to the Jacuzzi Jets switch. I believe you will find it advantageous to have the control right there at the Jacuzzi. Think about those Fall Evenings when the last thing you want to think about is straying very far from that 98 degree water. Note the beauty of the RSUB200 are that they feature a built in crossover and can be connected directly from the AMP300/Speaker Selector in line with the pair of AP650. I would recommend setting the impedance Jumpers to 4X in the SSVC4 speaker selector (4x for all four Volume Controls). You will have to remove the cover (roughly 8 to 10 screws. Then set the OVC300 to 4 X as well. But wait there is more. If you locate your equipment at the bar you can also add a Powered Subwoofer (like our OSD P-10) to be placed under the bar for more effect. You would connect it to the RCA Line 2 Output with an RCA patch cord. You just need to make sure you use Line 2 for your primary source. Line 2 Output will only output whatever is connected to Line 2 Input. You would still have the Line 1 to input a second source (but no output to the powered sub, the other three sub200 will play from either 1 or 2). I would envision using a Lap Top loaded with your iTunes Library and also hopefully a WiFi connection so you could take advantage of the extensive streaming content on line. That is the beauty of technology today is your source choices are amazing. I would love to see your actual plans. Please feel free to contact me directly at tim@osdaudio.com for further clarification. I would be more than happy to provide a wiring diagram. Thank you for considering OSD Audio branded products.

I have six pairs of old, worn out speakers where three pairs are around three sides of my pool; one pair on the patio; one pair in the jacuzzi area and the last pair in the bar area. This amplifier with your AP640 speakers looks to be the ticket. I want to be able to shut off any combination of the six "zones" from one location. Other than individual volume controls, do you offer a speaker selector unit that will do this function after the MX1260?
1 Answers
Hi Troy: We do not have a Matrix type Speaker Selector that would feature 6 inputs to six outputs which you would need to work with your application and the MX1260. I would recommend instead our AMP300 with a SSVC6 Speaker Selector. It would give you on/off capability for all six zones plus add some extra control with the internal volume controls. The AMP300 adds automatic source switching between two sources as well. You would have plenty of power as well. The other option is to add volume controls in each zone if accessible. We have excellent outdoor volume controls and recommend utilizing outdoor volume controls for each pair. It really comes in handy when trying to adjust the levels right there where the action is taking place. You would then use our DSM6 speaker selector without the internal Volume Controls. Good luck...

Would this amp be sufficient to power 10 speakers (AP650 High Definition Pair 6.5" Patio Speakers)? The application is background music for restaurant. Thanks.
1 Answers
Hi Dave: Yes the MX1260 would provide ample power for your 10 speakers (or 5 stereo pairs?). You also have an option of adding Powered Subwoofers to the system as well for after dining time (the unit features dual signal level pre-outs as well). You can also add Volume controls in line for each pair of speakers if so desired (would recommend our VKR120 Resistor based volume controls). Another choice to consider is running a 70V system using the AP650 speakers with the optional 70V tap (a $10.00 additon per pair). The PA90 commercial 70Volt integrated amplifier may be more applicable for your background music. See the PA90 on our site under commercial amplifiers. It features three microphone inputs for paging as well. It would be best to home run all the speaker cables back to the central location so you have the option of either running the MX1260 or the PA90. The PA90 is a single mono connection to each speaker. The MX1260 would connect a left and right to each zone (5 of the 6 zones). Both amplifiers will allow multiple source connections. But only the MX1260 will allow you to play different sources to to select pairs. So if you had a back dining area or seperate area for meetings you could plug in a dedicated source for those areas with the MX1260. So you have options, the MX1260 will provide flexibility plus more than enough power. The PA90 maybe a more affordable solution but limited in output power. Please do not hesitated to contact us if you have additional questions. TL

I just moved into a new home that has the backyard wired for outdoor audio. There are 5 sets of speakers wired into the entertainment center (10 speakers - 5 sets of wires), plus my indoor speaker system. I currently have it all wired into a 2 zone Onkyo receiver. I want to up-grade my hardware but am not sure what to get. Is the recommendation to wire a 6 zone amp like the MX1260 behind the receiver to provide a dedicated zone and power to each set of speakers? The indoor and outdoor sets can still be run separately if so? Should I run the inside set off the receiver directly and the outside speakers off the amp? Looking for general hardware set up input. Thanks.
1 Answers
Stanton, That would be optimal to use the MX1260 its a major step above the amp/ speaker selector system. I cant recommend this amp enough, it leaves you room to expand as well with 6 zones/ 12 channels. You can run your internal setup from the existing receiver and drive the outside with the MX1260 from zone 2 output. Can you tell us which Onkyo Reciever you are using? CL

Hi Jean-Eric, The MX1260 would work perfectly for your application. Connect the signal level outputs from your sound card directly to 8 of the 12 channel inputs of the MX1260 (leaving four open channels). There are removable speaker connections (green connectors) that feature four connections per zone (right and left, positive and negative) that account for two channels each. Set each of the eight channels as line in. You would still have four channels or two zones to use with direct input or from one of the two bus sources. TL/MA

January 31, 2012
I'm not sure which amplifier to buy; the MX1260 or the AMP300 High Definition 300W Amp. I have a story home with 12 zones. The speakers upstairs are Zone A and the speakers downstairs, in the garage, on the patio and the deck are Zone B. I've noticed all of the speakers downstairs are not at the same volume as the speakers upstairs. In fact the speakers furtheest away from the audio closet have softer volumes relative to their distances from the receiver. All zones have individual impedance matching volume control and the receiver is the master control volume. The speakers on the patio and the deck are the weakest sounding of all the speakers that are downstairs. I want to add an amplifier to just Zone B but not sure which one will be best. Oh I almost forgot, I have the speakers running through a 6 speaker selector box for each zone. Specifications on the audio equipment: Receiver: Pioneer Audio/Video multichannel VSX-918V All speakers: 8ohm 100watts rating (instaled either in-wall, mounted, or in-ceiling. Volume controls: 8ohm matching No subwoofer Should I turn off the impedance matching on the receiver and let the volume control do it? I am also wanting to install an IR receiver either above or below the volume control on for each zones. Do you have a kit that will do the job? I already ran the IR wire when the volume control wires were being ran. All of the wire was done during construction of the house Any help or recommendations you have will be greatly appreciated! Thank you for your help with this!!
1 Answers
Hi Dante: We would recommend the AMP300 based upon the Pioneeer multi-channel receiver you are using. It does not feature a signal level Pre-amp output. The AMP300 has an option where you can connect the Speaker level outputs from the Speaker B directly to a high level input. It then steps down the amplified signal back to pre-amplified. According to your setup you should have an impedance matching volume control for each and every zone located between the two six zone Speaker selector. Six zones for Speaker output A (also labeled front speakers) six volume controls and six pair of 8 ohm speakers 100 watt speakers. You have the same setup for the downstairs and outdoors on Speaker B, six zone speaker selector, six IM Volume controls and six pair of 8 ohm 100 watt speakers. For both A and B your impedance matching volume controls all should be set to 8X and you should make sure the protection switch on both of the speaker selectors is diables (turned off). Volume on your system should be determined with all volume controls at full volume all the way clockwise (where they have no effect). Set volume at accepatble level and then use the volume controls to turn the sound down. By adding the AMP300 you will be able to increase the volume level of zone B while making the Zone A more efficient once it only has to worry about powering the single speaker output (A). I like that you have prewired the IR for each zone. Are the preterminated with sensors? We are currently developing our IR product offering. I can recommend a site you may want to contact for more information...

Does the input for this amp have to come from the preamp or can I input directly from the speaker connections on my receiver (the amplified outputs)?
1 Answers
Hi Jim, The MX1260 features preamp signal only. There are two sets of universal inputs to choose from or you can input directly to a zone or individual channel. There is no speaker level (amplified inputs). Our high current two-channel amps (AMP200 or AMP300) feature a choice of signal level (pre-amplified) or speaker level inputs (amplified). This along with a speaker selector works better when you do not have a signal level output from your receiver. TL/MA

what is the impedance limits min/max per channel?
1 Answers
Hi Mark, It all depends on what you are trying to accomplish. This is a 12-channel amp that is grouped into 6 stereo zones. You can connect two pair of 8-ohm speakers in parallel to a stereo zone which would be a 4-ohm load to the stereo right and left channel of the stereo zone (example: channel 1 and 2, stereo zone #1). In the single channel bridged mode (80 watts), you can connect a single summed mono stereo speaker, which needs to be 8 ohm. You can also bridge two channels together for 160 watts; however, you can only connect a single 8-ohm speaker. This amp also provides dual source through the BUS connection or you can connect each channel or each zone directly to a source. Please let us know if you need additional info. It would help us to know what you are trying to accomplish (i.e., what speakers and sources you are using, how many zones, etc.). TL/MA

Great idea when it works.
Can't handle high input loads from a McIntosh preamplifier without a pad in between. Zones can be set up, but must have a pad between the amp and speakers to control volume locally. Output from the amps is on the back side and is a one time set up since it can't be easily controlled from the front. The led lights are a sometimes working on auto and sometimes not working on auto. One of mine doesn't get the message although it amplifier works fine whether or not the led goes on or stays off. One incredibly good thing is that the tech guys at OSD are very helpful and easy to contact by phone. This makes all the difference when you are doing set-up on this amp. Kudos to OSD and their staff.

Waited ten years for this
I built my house 10 years ago with 5 rooms wired for speakers. All powered options at the time were very pricey dwarfing the cost of my media receiver. And I never got comfortable running an impedance matching speaker selector and risking over-driving my receiver's zone 2 or 3. Although a little pricey, the MX-1260 has great sound and plenty of power for sound distribution around the house for quite a bit less than the competition. It accepts two input sources for use by all output zones as well as a dedicated input source per output zone. My only complaint would be the placement of all controls and inputs on the back. It would be perfect (5 stars) if an ad hoc input port and the input selectors were located on the front panel. It assumes a pretty static environment and little or no changes between sources in each output zone. Reaching behind and through a lot of wires to change sources seems a bit short sighted. If you're looking for whole house sound distribution, understand this is a multi-zone power amplifier, and the receiver providing the input material needs to provide analog pre-amp outputs to feed the MX-1260. The documentation is a bit thin but sufficient since it is a power amp. Not a lot of bells and whistles to deal with. This unit is perfect for my needs and I have been very pleased I made the purchase.

Worked great! (with the other receiver.
The product worked great on my Denon 3310ci, where I could control the volume from my iPad (through DeRemote), but the 3310 does not include AirPlay, which was a deal breaker for me and I had to send back. The 3312ci, which does include AirPlay, but I cannot control the volume of Zone 2 or Zone 3 through DeRemote. So, even though the unit was used (but still looks brand new), OSD agreed to accept the 1260 for a full refund. It will be very close to the 30 days clause, and I didn't have all of the original paperwork, but they said they would accept the return. I haven't yet received the credit, but I doubt that they have received the unit, yet, either. I have also purchased two outdoor speakers, that will be hung today (from OSD) and intend to buy two more. Overall, dealing with OSD is/has been a pleasure. Thanks in particular to Brennan.

Great Amp for a Great Price!
I researched Multi-Room Amplifiers and seriously looked at the Niles SI-1230. After talking to both Crutchfield and OSD I decided on the MX1260, mainly for the price but it also provides more power. It is well built and attractive (and heavy as hell). I am not an audio enthusiast, but do enjoy crisp, clear audio and this amp does it. I plan to pair it up with an Onkyo TXNR609 home theater receiver to get all of the benefits from the amp. I have six zones with volume control for each zone on the wall. For now it works great by just plugging in my iPod directly to the RCA input. I am very happy with the purchase, especially the price!
