review of the black 4 channel amp, with 4x red physical volume knobs (and an antenna out the rear) - There aren't many 4 channel amps of this form factor /type available. In my case, the new home I bought, in the bedroom there were already four in-wall speakers with the speaker wiring to behind the TV. I have an LG C4 TV I mounted to the wall so I didn't have the space for a normal full size audio receiver. This has worked great for ~six months now, it was the only option I could find that had individual knobs for each channel, which was important in my use case.I mentioned the model TV I have as it's actually very important, the LG C3 has an analog audio headphone Jack output which is what you would normally use to go from TV to this type of amp, however LG being cheap, eliminated that on the newer C4 line, which forced me to use Bluetooth audio from the TV to this amp (if i wanted to keep volume control via the TV / TV remote, which ofcourse you want!).In this setup the only other option was to use the digital audio optical cable out from TV and then use a optical -> analog converter; I tried this, it worked, however with that you lose all volume control on the TV/remote (and with this mounted behind my TV i wouldnt be able to easily access the physical nobs to adjust volume). this is normal for digital/optical audio output, as its ment to be fed to a full size audio receiver and you control the volume on that device.So I had to go with my least favorable option, and that is to use Bluetooth audio from the LG TV to this four channel amp, I expected it to give me alot of trouble / disconnects / re-pairings based on other things I had read, however that has not been the case at all. The Bluetooth connection has been flawless from the first day I paired it to this amp. Range is not an issue here as this amp is touching the back of the TV (zip tied up behind the TV) It's been about six months now and I have not had ONE issue come up. I used the TV every night and with this setup I can still control the volume from the TV remote (or in my case my apple tv remote which itself via IR controls the TVs volume). very happy with this amp.sorry i dont have a pict of the amp in use- This was the only photo I have right now, but it is place right behind this mount, mounted to the TV itself

Works perfectly with my BST-1 bass shakers. Individual volume controls are ideal for fine tuning haptics. Some say the speaker connectors are too close together but all that's required is to tin the ends of of the wires to prevent fraying. Small form factor makes mounting or finding enough room for the unit a breeze. Highly recommend.

2 speakers in the kitchen and 2 in the living room. All adjusted perfectly so when I walk from room to room the music is at the right volume everywhere.

Shipping and delivery from Douk Audio very fast and painless.I'm using this to drive bass shakers on a Sim Rig. I was uncertain about the connector as this isn't (or doesn't seem to be; the feature descriptions are ambiguous) a USB sound card, but it installed easily and perfectly as a Bluetooth audio device which turns out to be much easier than yet another USB connection on the rig.The build quality is really impressive at the price and it works well and feels very robust.I was using the other well-known and popular brand cheap little USB 2x50W solution - had no problems for a year then mine failed and its replacement failed for no clear reason. This solved the problem and has given me the extra channels to add a couple more shakers when budget allows.
