Lifetime Tech Support

Design and customize a home theater that fits seamlessly into your home decor. Or go big with complete, whole-house audio solutions. Whether you want to maximize your home theater experience or transform your living space, OSD Audio has total solutions to help you get the most out of your movies and music--from clean power amplifiers to in-wall and outdoor speakers, subwoofers, custom controls, and more.

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.

Dave "D*Sol" Rivera • 12/17/2019, 2:17:43 PM Q 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.
Customer Service • 12/17/2019, 2:17:43 PM
A 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
jason • 12/17/2019, 2:17:43 PM Q i have one of these and am buying another. the unit has been brilliant except one channel has ceased to work. i switched speakers to make sure it was the amp and not my speakers but to no avail. i don't run the thing hard at all but one day i just noticed the speakers in my bath stopped working. is there any other diagnostic i can do and what is the warranty period. as i said i am buying another to add more zones to my system but would appreciate any insight on the original unit. thank you, jason
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Jason, If you are certain it's the channel, we would take a look at it under warranty and repair or replace it for you. Please email for an RMA #. Also, we have the printable warranty form to include in the box when you mail it back to us. If you scroll all the way to the bottom of our homepage, under the category Support there is a link: How to Return a Product. In the meantime, hook up your new MX1260 to your existing system. Thanks for being such a loyal customer. CL 712
Troy • 12/17/2019, 2:17:43 PM Q 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?
Customer Service • 12/17/2019, 2:17:43 PM
A 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... TL
Troy • 12/17/2019, 2:17:43 PM Q 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.
Customer Service • 12/17/2019, 2:17:43 PM
A 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 for further clarification. I would be more than happy to provide a wiring diagram. Thank you for considering OSD Audio branded products. Good luck... TL
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, 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
