Great inexpensive amp w/multiple power options and adjustable volume. Perfect to hide in a cabinet.
So I've actually bought 3 of these over the last few years. #1 I used to power a pair of atmos speakers with a 12V trigger line to turn it on from the AVR. #2 I used in the living room to drive a pair of bookshelves for casual listening using using the signal autodetect. The pass through RCA inputs go to a sub. #3 I used in my home office to drive a air of bookshelves using the signal autodetect. Maybe they aren't "audiophile" quality, but they have good sound even when using them at fairly loud volumes. The power on and off works reliably both with the 12V trigger as well as the signal detect. There is a "volume control" adjustment on the back of the amp meant for adjusting peak volumes more than anything else. I'm not sure if it really adjusts the output or just attenuates the incoming signal, but its mandatory to tweak it when using the signal detect function for power on. In my office, when I'm listening to music at a low volume while I'm working the amp would occasionally cut off due to the small input signal on quieter music. So adjusting the volume on the amp down about 30-40% means I can run the input at a higher volume level to make sure the amp stays on while still keeping the speakers at a reasonable volume level for background music. And even though I'm giving up on max power, the amp still drive my 89 dB sensitivity bookshelves a lot louder than I want to listen in my office so practically I'm not losing anything. Runs at fairly minimal heat and even after some spirited use in the living room where its mounted inside a cabinet with the door shut its not hot enough to worry about. I think its a good power level and feature set at this price.

Has all the needed features.
I am using this item to power the rear high surround speakers in my Dolby Atmos 7.4.4 setup. Yes I have 4 high speakers, 2 front, 1 center, 2 surround, 2 rear surround, and 4 sub-woofers (1 in each corner of the room). Powered by Onkyo TX-RZ920 9.2 4K UHD Atmos receiver. The 2 extra rear high channels are fed from the pre-out jacks, and that's what drives this Monoprice amp. In case you are wondering, 2 of the sub-woofers are part of my front speaker setup, configured as full-range. The other two sub-woofers are connected to the Onkyo sub1 and sub2 outputs. Many people do not realize the incredible difference that balanced subs can make. Now, back to the Monoprice amp: It is so well designed and configured. I like the fact that you can choose to have it auto power-on, or be triggered from the 12V trigger of the main amp. The unit is compact, sturdy and comes with heavy duty brackets for wall mounting or stacking. There is also the ability to bridge the amp, or to select 4 or 8 ohm output. The volume control is an almost hidden turn screw - great for this application - no chance to accidentally change the volume after you have carefully calibrated the whole system. The amp silently comes on when needed, and turns off some time after the music stops. Perfect. My only minor issue is that the speaker connector could be more robust. On the other hand, it is designed to connect all the wires to a single plug, which is very handy for installation and maintenance.

Great Value for Money and Very Compact, But Not Too Powerful and Not Audiophile Sound
I have bought two of these to replace a different power amp with A/B/A+B switching that proved to be very lacking in power output, nowhere near what it says in the ad, even when driving just a single pair of speakers. My two Monoprice Unity 100s will be used to drive a pair of speakers in the ceiling of our dining room and a second pair out on our covered patio. For this type of service where you really don't need hundreds of watts or audiophile performance they are ideal. If you think you're getting audiophile performance from a Walmart priced (but I assure you not quality) product, think again. If you want more watts for your Atmos or rear surrounds or whatever, I would think about the more expensive 200 model, however. First of all the likes: 1. Price - at $125 and change these are excellent value for money for use as a modest power amp for, say, Atmos speakers or, as I am using them "muzac" service around the home. 2. Built quality - very sturdy cases, nice and solid, well finished. 3. Size - very low profile and only half the width of a standard hifi box or AV receiver, meaning you can put two side-by-side in your stack without taking up too much headroom. Rack mountable too with brackets supplied. 4. Heat (or lack of it) - being class D amplifiers they don't create a lot of heat, which is good. Things I don't like: 1. Volume knob on the back - might be okay for "set it and forget it" use, but for balancing speakers out it may be an issue for some. There's plenty of room on the front panel for a volume knob, I can only think hiding it on the back meant they could use a cheaper one (see below). 2. Volume knob is very small and needs a screwdriver to turn it. 3. Volume needs to be cranked up all the way anyway so why bother? 4. Speaker connections - you have to strip the wires and insert them into a block, tighten the screws down. The blocks will only take 14 awg wire at most, and you have to be careful not to let stray wire strands short out the connections - they are VERY close to each other. I have to reconnect my wires for a different reason this weekend, and I am going to take the opportunity to "tin" the wire ends with solder to give me solid ends to fit into the connector block. Sound quality? Jury's out on that one. To be fair I'm hardly using a pair of top-of-the-range hifi speakers, just modest built-ins, but I'm not expecting audiophile quality from a $125 amp either. Should be perfectly fine for Atmos or rear surrounds or muzac service though.

$100 paper weight.
It lights up but absolutely nothing happens. No audio at all. Not even sure what’s wrong but think it’s the super flimsy speaker output connection. It’s exactly like car stereo amps but very cheaply made. I’ll attempt a couple more hook ups to eliminate any errors on my part and update my review.

Amazing Little Amp [UPDATED 2023]
Updated review [2023]: Still working great! I said I would come back and update to five stars if they lasted. Well they did. And here I am updating to five stars. Original review [2018]: I have had mixed experience with Monoprice quality. I was skeptical of these. But I got four of them and racked them up for use in a whole house audio system connected to a Denon HEOS SuperLink. They have all the features needed for a custom install like mine. The HEOS powers them up by a trigger and with the trigger passthrough on the amp I can also power up my fans when the amps are on. When in standby mode they power on within 1-2 seconds of getting the trigger signal. The layout on the back is logical and not crammed together making for a quick install. The rack mounting kit is good and the ability to mount two next to each other is very nice. And these things have a LOT of power. I currently have the volume set to about 3/5ths and it is just too much power for my rooms. I have to keep the variable control on the HEOS down very low. I plan to turn the amps back to about 2/5ths or 1/3rd so I have more control through the HEOS app. Since I just recently installed them I am hesitant to give them 5 stars and I don't know how the longevity will be. If they last a decent amount of time without dying I will come back and increase to 5 stars. Honestly, I have done tons of research and gone through various iterations on my DIY whole house audio system. The HEOS SuperLink combined with these amps is just spectacular. I can't imagine any combination would do better.

Died in about a year+
Worked fine when it worked. But died in less than 18 months. Something's probably wrong with the design or component quality.

Atmos ceiling speakers = no problem for this amp
Needed a small amp for my 2 ATMOS ceiling speakers and this one fit the bill perfectly. Small size, 12 trigger, enough power for my 6-1/2" speakers. Only negative are the set screw type speaker wire connectors but for the price paid, and the application, this is not an issue for me.
