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.

mike • 12/17/2019, 2:17:43 PM Q 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?
Customer Service • 12/17/2019, 2:17:43 PM
A 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
Richardd • 12/17/2019, 2:17:43 PM Q 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!
Customer Service • 12/17/2019, 2:17:43 PM
A 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
anthony • 12/17/2019, 2:17:43 PM Q how would you control the volume on each of these zones?
Customer Service • 12/17/2019, 2:17:43 PM
A 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
Bill • 12/17/2019, 2:17:43 PM Q 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.
Customer Service • 12/17/2019, 2:17:43 PM
A 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
victor • 12/17/2019, 2:17:43 PM Q product say rack mountable, is rack mount shelf or are there mounts that attach to unit Vic
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Victor: Yes the MX-1260 is Rack Mountable but we are currently out of the actual Rack Mount Ears. It will be 45 to 60 days before we have the replacement. The Unit will fit on a Rack mount shelf otherwise. TL/4378
