DUTISON 100W Dual Channel Wireless Bluetooth Stereo Mini Amplifier - USB Audio Receiver for Powerful Sound

M. Wayne Carpenter: I didn't care about the bluetooth feature.. I don't use that for anything. But this was my primary sound source for one of my computers. The unit lasted 95 days.. (3 months, 3 days) and has now failed. Turning it on, it does it's little self check routine and then presents itself as a fully functional. About 3 seconds later it goes back to the self check routine and stays there with highly garbled audio output. You get what you pay for and this is proof of that. Complete garbage.

Oldsong: I installed this unit in my shop and it works great. I just plug a USB stick in with my music on it and it plays for hours at a time. It even sounds pretty good.

mrredpantsmrredpants: My needs for this amp were basic - I have a 1byone record player with powered speakers. I just wanted to be able to control volume with a remote so I didn't have to get up to turn record up and down. When I hooked it up, the sound was great. The remote was very hit or miss. I was set to return it and decided to do some investigating.

If you look at images, the IR receiver (NOT RF) is not positioned well. I THINK their intent is to have the signal pass through the clear ring around volume knob. Obviously not a good design. Out of the case, the remote works great. So, my plan is to either just leave it out of the case (which is fine) or I'm going to Dremel a small hole where the red square is to allow better transmission of IR remote.

Just keep this in mind when reading reviews about remote or how you're going to use this device.

Bailey T.: I bought this to power two small bookshelf speakers I had set up in the bathroom. Initially when I opened the package mine did not come with a power cable included at all. I luckily had one laying around for an old router that matched the port on this, so that was annoying to start. For the first day the amp worked awesome, drove my speakers fine, went plenty loud, and Bluetooth connected and worked no issue. The second day of use my music would cut out and a loud banging/record screech sound would come out of the speakers and then resume playing music. It did this through Bluetooth or wired in with the RCA connectors to an AUX cable. The third day I couldn't get it to make the noise like it did so many times the previous day and seemed to be working fine without issue. If the cutouts come back ill be returning this. You get what you pay for, a $30 amp sold under multiple different companies. Also the remote works but only from very short distances and have to have it pointed directly head on with the unit, even from a slight angle it wont work.

Update - After that first day the banging / record screech sound never came back and has been powering my bookshelf speakers...

C5Driver: Don’t know about all the 1 star reviews but with anything you have to read the instructions and have the correct power supply as this doesn’t come with one. I’ve had my little power house amp hooked up for months in the hot AZ desert. The little amp powers 2 in ceiling speakers in my back patio! And the sound is great. The Bluetooth works great! I’m able to hook up my phone and other BT transmitters with ease. The only downfall it only allows one BT connection at a time. It draws very little power so you can leave it on. Hope this helps!

Nicholas Needham: Works well, missed the part of the ad that states it doesn't come with a power cable.
