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.

Joel • 12/17/2019, 2:17:43 PM Q 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?
Customer Service • 12/17/2019, 2:17:43 PM
A 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
GEORGE CISNEROS • 12/17/2019, 2:17:43 PM Q I have an installation that needs twelve mono inputs distributed to twelve loudspeakers. This a muséum exhibit with multiple areas of sound information. Does the MX1260 solve my situation? The picture only shows two pairs of stéréo RCA inputs and can these operate simultaneously? Would I need three MX1260's to get twelve input channels?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi George: Checkout our Pre One which is a Pre amplifier that has a stereo mono switch which would allow a couple of different inputs (sources) plus a Mic Mixer. But the key is the Mono switch that would give you a right and left mono signal that would be connected to the Bus 1 input of the MX-1260. You then set each channels input switch to the BUS 1 in. The universal bus will send 6 right and six left channels all of which will have been converted by the Pre One to Mono. You will have master volume control on the Pre One. Please let us know if this will work for you. We can help with speakers, wiring and also wall plates. There are additional options if you would want to add volume controls to pairs of speakers. We also have 70V options as well. For a diagram or additional options please contact me at TL/4685
SH • 12/17/2019, 2:17:43 PM Q I have determined I have 12 zones, with speakers in each in the ceiling Kitchen (2 spkrs), Livingroom (w/ Bose 4 spkrs), Dining room (2 spkrs), Sitting room (2 spkrs), Playroom (xbox one 2 spkrs), 3 porch locations w/ 1 to 2 speakers, 2nd floor Master bedroom (4 spkrs), Master bath (1 spkr), Guest Bedroom (1 spkr) I could reduce that to 7 by consolidating some zones if I have to. I have 1 sonos amp and 1 sonos connect and 2 alexa's currently at the house. All stereo wires are consolidated to where I have a rack. Can anyone provide some thoughts on how to best set this up. I have the MC1260 in the rack, and an receiver just above it. Just trying to figure out how best to configure this the best way possible. What else should I buy?
Customer Service • 12/17/2019, 2:17:43 PM
A Hello SH: Sounds like a lot of stuff going on, lots of speakers already installed (I am assuming). Do you have two home theater setups (5 speaker upstairs and 5 downstairs). If so what AVR Receivers do you have or are planning to purchase. Then 4 sources one being powered (the SONOS Connect Amplifier) And you mentioned MC1260 (OSD MX1260?). More images of you inside and outside plus front and back of your component rack. Maybe blueprints if you have them. It would be nice to create a spreadsheet listing each zone and what actual speakers you have or are planning to use. It would help listing brand and model for all components and speakers. is my email address. I do all the designs for Upload Your Plans. TL/4746
Pat • 12/17/2019, 2:17:43 PM Q Hi, I have an OSD MX1260 that powers my whole house system. We have 6 rooms, 2 speakers in each. Can I use a second smaller amp to have more power in 2 of the rooms? Which would you recommend and how do you connect them? Thank you!
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Pat: If you currently have one source connected to your Bus 1 input and supply the source for all six zones a simple way of increasing power to two of your six zones I would add an AMP200 to supply the first zone you want to have more power (you can even add a second pair of speakers for that zone as well. You would still have bus 1 supplying signal to zones 1 thru 4. Now connect Bus 1 output to Bus 2 input with a short RCA patch cord and then connect Bus 2 output to the AMP200 Line 2 input. That would take care of 1 to 4 and your 5th or prime zone but that would leave zone 6 the second zone you wanted more power. Here we connect a another stereo pair of RCA cables from the Line 2 output of the AMP200 to the Zone 5 (left channel input) and the the right channel connection to the Zone 6 right channel input. To make this work you set the Left input switch on Zone 5 to line in and switch the stereo/bridge switch to Bridge/mono. Then make sure you set the right input of zone 6 to Line in and set the mode switch to Bridge as well. You would connect the left speaker of that room/zone to the bridge outputs of the Phoenix connector Red to positive and black to negative. Then do the same with the right speaker in that zone, red to positive and black to negative. That will double your power in Zone 6 from the two bridged zones (5 & 6) and the AMP200 will will provide more power to your other zone you were looking for more power as well. Let me know if you need a diagram... Simple, right TL/4764
anthony • 12/17/2019, 2:17:43 PM Q will the mx 1260 run 8 speakers at the same time playing the same music? I will be using a zenith 3000bt hybrid dj amplifier as power
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Anthony: The MX1260 is a 12 channel 6 zone Power Amplifier featuring dual universal Bus Inputs. It has a switch for each channel; Bus1, Bus 2 or line in(direct) input. Each channel features a 60 Watt 8 ohm amplifier. There is a preamp output for Bus but not a preamp out for each channel. It sounds like you need a multi-channel speaker selector that will work after your ZENITH 3000. Something like our TSM8 with selectable impedance protection. Regarding the MX1260 each channel will handle a 4-ohm load, and the Zone is bridgeable (that would limit you to 6 channels versus the eight you asked about). Otherwise, the MX1260 would be a stand-alone Multi-Channel Amplifier where you add a source. And we now have a Wi-Fi app driven solution with our new NERO Link. TL/5519
