    Unity Wall Mount 35-watt Stereo Power Amp with Digital Input and Subwoofer Out

    The good news is that TVs are getting thinner and lighter every month. The bad news is the physics of sound require space to develop bass. So we have huge fantastic looking picture with sound that is worse than your old 13" TV/VCR combo. Cluttering up that sleek sexy new TV with a big 'ol stereo may not be exactly what the room is calling for.

    This 2-channel power amplifier features a stereo speaker output, with support for 4-ohm and 8-ohm speakers, and a line-level subwoofer output. It includes RCA stereo analog inputs, as well as 24-bit/96kHz S/PDIF digital optical and digital coaxial inputs for maximum flexibility.

    Its built-in IR learning feature allows you to use not only the included remote control, but also any other remote control for the volume and mute functions. The panel-mounted IR sensor is augmented by an external IR sensor, which allows you to hide the amp behind a television or inside a cabinet. Measuring less than 2" deep, this amp is designed to mount to the back of your TV or to the wall so you never see it again.


    • Class-D amplifier providing 35-watts/channel (RMS) into 8-ohm loads
    • 24-bit/96kHz S/PDIF digital optical and digital coaxial inputs
    • 4-pole speaker detachable screw connector and line level RCA subwoofer output
    • IR Learning for basic volume control and muting
    • Small footprint with wing mounting options for discreet installations
    • Built-in thermal and short circuit protection circuits

    Super handy
    The amp is super, but the instructions are incorrect. I send one back because I couldn't get it to work properly. It has a very handy IR learner function for volume+, volume -, and mute, but if you try to program it as described, it won,t work. When I noticed the second unit behaving exactly like the first, I started to experiment. Here is the deal: To program IR commands press the IR learner button until the red indicator LED starts blinking. Hold the remote in front of the learner window and press Vol+, The indicator light will blink twice, NOW YOU MUST PRESS THE IR LEARNER BUTTON ONCE OR IT WON'T WORK! This critical step is omitted in the instructions. Once I realized this, everything was fine. The amp sounds great, and runs very cool. Wrong instructions takes away from what should have been five stars.

    Great little amp for TV installs.
    Used this for a conference room TV replacement in a room with external speakers and a powered subwoofer. The old amp was a household HDMI switching amplifier. There were constant issue with the sound. With this little amp, I can take the optical out from the TV and power the speakers and subwoofer. Best part is it has a IR learning function, and a remote IR sensor, so I can use the volume control from the TV remote to control the amp volume and don't need another remote. Amp itself is mounted inside a cabinet under the TV, but is designed to wall mount too.

    The first one of these I got had an issue where the volume wouldn't change, and was stuck on very, very low. I was irritated, but Monoprice RMA'd it, I had the new one in a week and it works great.

    Good sound for the money
    I bought three of these and installation was easy and you can also program Apple TV 4th generation remote to control volume so you don't need to use additional remote. Sound quality is pretty good.
