Stereo Audio Amplifier for Home Speakers S-288 Bluetooth 5.0 HiFi Mini Audio Component Amplifiers Receiver 4.0CH RMS 40Wx4 Max. 600W Integrated Power Amp W/USB,FM,Adapter

I use these units to add Bluetooth and FM radio to 1930s and 1940s vacuum tube radios. Tap the output into the volume control and there we are...good sound, adds new life to old AM/SW radios. Not perfect but fairly good.

I was pleasantly 😮 Surprised at How Functional this Amp is as well as the Power. Love the Features (super compact size, FM/AM Radio Tuner, slim Remote, Bluetooth connectivity <to my Cellphone>, Digital display, crisp Sound Quality, and RCA Cable output) plus the Power it delivers to my POLK Patio Speakers.

I needed a receiver to hook up to a built in home speaker system. For a very reasonable price this actually works quite well. It did take a little bit to figure out how to hook up exactly right with my system so that all the speakers in the house worked correctly but we got creative and figured it out. Very easy to pick up Bluetooth using phone. Does have a funny beep when connecting but it’s not a deal breaker. Hopefully this has longevity.

Had mine on an atv and it was submerged under water and rained on a lot and still hooks up to blue tooth and still sounds perfect very much recommended

Easy to install in my boat, great sound lots of power.. Great bass.. well worth it

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.

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

Muy bien 👍 gracias está súper fantástico
