Excellent product plenty of Power output a will power high end speakers. First unit arrived but the Bass control did not work. Vendor replaced it with expedited shipping and free return. Infant mortality is a term used in the industry to define a product that fail prematurely such was the case with the first order. CAUTION: When each unit arrived, the volume control was in the max position. Advise to turn the volume control full counterclockwise to avoid blasting your speakers

Working great in my garage running from a cheap (99 buckeroos) FireTV for all the YouTube tutorials and Music to work along to.All the input and tuning options you need.I set it at a medium volume and use the TV to control the ultimate volume.Hooked up to a set of bookshelf speakers and can still rock the garage.Two thumbs up from me.

buena, bonita y barata si tiene potencia algo decente aunque cuando le alzo el volumen y lo quiero exigir se calienta y distorsiona sonido, para un volumen intermedio o para una habitación pequeña o mediana si esta bien.

Small and loud for a receiver nice..

Should work just fine

My requirements: Small, Light weight, sounds decent, cheap.Be prepared with a powerful magnifying glass if you want to read the manual, which is written in transliterated Chinese. Power cord is 3' long. There's no cord supplied for the 12V power input, so this was not tested. Knobs are black with a black notch to indicate the position - very difficult to read. The unit forgets the FM station when turned off. The unit shipped with the volume knob turned to max. Be careful with that initial test!!! Line input is RCA, and outputs are the old wire clamp method. Remote control uses a 3V CR-2025 watch battery (supplied). The volume buttons on the remote were confusing - they allow you to change the volume up or down UP TO THE SETTING OF THE VOLUME KNOB on the device. Bluetooth worked, but seemed to require a higher volume setting than radio or AUX input. The manual is silent on what type of microphone can be connected. I used an ancient Realistic Highball-7 (impedance 600 ohm) mic that was at the bottom of a box of unused gear. It worked OK. Couldn't get music to play from a USB memory stick at all. It just didn't recognize it. Using an old SD card did work. Is it possible that the player doesn't recognize newer types of USB sticks? USB sticks are typically compatible with older devices that try to read them. Luckily, playing from USB sticks was not something I need to do with this device.

Purchased for Home surrounding system: solid case of metal (not plastic). Tested all functions except mic and worked as expected. Output power is enough for home use. Blue tooth connection is very reliable with 30-40 feet . Sound quality is acceptable ( depending on sound source). FM radio signals are little weak. USB/MP3 playback is good. Remote control well designed. Two shortcomings: 1 a loud sound comes out when switching functions and no way to make it quiet; 2 poor user manual and operation instructions.

For such a small package the unit performs above expectations. I was looking for this kind of amp for outdoor projection movie night. It is amazing how much the op amp chips have been developed and how good they are. Have it hooked up to tannoy outdoor speakers that are high end components. At 12 o’clock it was way to loud, enough that the surrounding neighbors would not be happy. Blue tooth was fast to connect and the stereo separation was huge. The FM locked on to 40 channels with real clarity take note this was outside not inside the home. Couldn’t tell if FM mode was stereo like you could hear in BT mode. Hooked up to a Rotel tuner to the Line input, could of been a cd player, cassette deck anything with rca jacks. If you have a built in pre amp in your turntable your good to go with line input. No pre amp, you will need the addition of a pre to use your table. Tone control worked way better than expected. The treble knobs performed better than the bass control. The bass control is ok but depending on the music it can be lacking. It has no protection mode you want to blow a channel short the speakers wire together and she will most like have a component failure in that channel. 30 dollar throw away component is just unbelievable cool unit to play with. I can finally see myself buying high end class D amps with changeable op amp chips they come that far in performance.
