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.

Joe • 12/17/2019, 2:17:43 PM Q How are bridgeable output used or why do I need them?
Customer Service • 12/17/2019, 2:17:43 PM
A 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
Daniel • 12/17/2019, 2:17:43 PM Q I was thinking of putting in a Sonos system in my home. I have 2 outdoor speakers (1 zone), 2 in the living room and 2 in the kitchen (2nd zone) its basically 1 large room. 2 in the bedroom, (3rd zone) and 1 dual in the bath for a 4th zone. I was explained that a10 to 12 channel amp along with their Sonos bridge components would work great. The question I have is that the stores are telling me I need to buy a Niles $1000, $1,400 Amp. Would something like this workout for what I am doing? Thanks for all your assistance.
Customer Service • 12/17/2019, 2:17:43 PM
A 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
Daniel • 12/17/2019, 2:17:43 PM Q 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

A 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. We call this addition by Addition where you still utilize what currently have. TL 1241
Luis • 12/17/2019, 2:17:43 PM Q Does this include a remote? If not, how would I select the zones?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Luis, The MX1260 allows you to customize what is playing with the controls on the back. This could be adjusting the gains to zero for zones you do not want on or switching to one of the multi-sources that are on and connected or not connected. Also, this unit should be used with volume controls if possible for control in each zone. CL/MA 1286
Setiawan • 12/17/2019, 2:17:43 PM Q I bought this amp (OSD MX1260). Do you have a recommendation for the best outdoor speakers? Are waterproofed from the rain? How about the column speaker TOA ZS-102C? Is it a good match.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Setiawan: We have a large selection of outdoor speakers that are weather resistant. For patio speakers, we recommend you mount the speakers under an eve or some sort of overhang to provide some protection from the direct contact with the elements. Our rock speakers are treated specially to handle harsh climates, although in severe weather we recommend covering them.The TOA ZS-10C you referred to are rated at 20 watts with a peak of 30 watts. They are also very efficient with a sensitivity of 93 dB. The MX1260, however, may be a little too much power for these towers. TL/MA- 1467
