I've been using it for several months and the sound is great while using the RCA input. Today, I switched to Bluetooth and the sound is also great... if you're standing right next to the amp. IDK if I got an outdated version, but my amp doesn't have the antenna input shown in the pictures, and the Bluetooth range is only about 5 feet.If you plan to use it with the RCA input, it's great, and the sound is awesome for such a small amp. However, if you wish to use the Bluetooth technology, be prepared to be disappointed.

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.

I am using this to run four ceiling speakers in a board room. The device looks well made. The sound is clean and loud enough for the room and the amplifier has the exact features I was looking for. Being able to control the speaker volumes individually was not necessary for this application, but it is helpful. Time will tell if the internal components hold up.

I purchased this to power my 50w bass shakers. It was very easy to split the subwoofer line to the amp and connect the speaker wires between the amp and shakers.I love that you can control each shaker separately so you can choose which seats to have on. It sends enough power for a great shaking experience.I am not using the Bluetooth options or for any other use.

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.

I received this product a while ago for a project and kept it laying around in the box due to project delays. I finally got around to using it, and it turns on for about 5 minutes and then shuts off. At first I thought it was being over powered, turned all channels down low and it still cuts out. I moved the cable to it own receptacle and it still cuts out after 5 minutes, super disappointing. I realize I am well out of the return window, but I emailed the company for support and to see if maybe it was a defective unit.... They have not gotten back to me. When it works, it seems to work well. I see other people have had luck, I guess that's why I'm so bummed. Just be cautious about what you're buying and know that it could have problems out the box. Maybe the company will reach out to me and replace the unit so I can re-review and give a higher rating.

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.

This has been a fantastic product so far for me. Initially got it as I needed a small receiver to fit in an awkward space where speaker wires were located (for reference, smaller than a standard 8.5 x 11 paper). Bluetooth was easy to establish on my phone....the only negative so far has been that I had to forget and re-pair the device once over the course of 2 months with daily use. Another slight negative, when using a google nest device to play music through the speaker it is often poor-performing (slight skipping/crackling), but this doesn't exist when using a phone.Overall, gets the job done and would purchase again (and will purchase again if and when this one dies due to the low cost for what you get).

UPDATE: Just after the warranty expired the Bluetooth capabilities failed. I contacted the vendor and while they would not replace the unit, they did provide me an essentially new unit by sending me an entirely new circuit board for $10 shipping. Swapping out the circuit board is fairly straight forward if you have done this kind of thing before. The replacement board now has a working Bluetooth connection. I have to give this vendor credit for basically replacing the unit out of warranty. I stand by my original review - it is a nice unit.ORIGINAL: I just installed this, so it's early. I have two sets of speakers in the same room that require a different volume setting in order to be properly balanced. This unit does a great job sending the same sound source to two different speakers. My sound source is a Mac using BT, so master volume is controlled on my Mac. The documentation is a little lacking - I have included a diagram of how the volume controls are mapped to stereo signals - I may have missed it, but I could not find it in the documentation. Overall I really like it so far.
