Herdioin Wall Audio Control Amplifier Receiver 2 Channel Wall Plate with USB Microphone Aux (3.5mm) Input 100Watt Max Module for Sound Systems Home Theater Integration Compatible with Bluetooth

Very easy to use. Bluetooth connected right away and sounds great. I hard wired it to 4, 8 watt speakers. Will be purchasing a couple more for future use

Very easy to install, pair, and use. The sound quality on my un-powered stereo speakers is amazingly good for such a small device. If I could make one change I'd put a timer or dimmer on the LED indicator lights. They are very bright and distracting.

Simple setup. Dumb wiring. Why put power port on the front? There is an adapter to power from the back but it still requires the power brick. Really stupid.

The media could not be loaded. This wall amplifier is awesome. Easy to use volume controls, Bluetooth connectivity, on/off switch and more. My concern was using the 12V power option as I didn’t want to see the AC power cord. My solution was ordering a $12 *transformer (see photo). I ran AC 110V power from a CGFI outlet to the transformer. I then ran a 20g wire from the transformer to the wall amplifier. I also used 14g protected speaker wire to the amplifier and they easily fit. Now with all wires hidden, it was time to enjoy the music. Bluetooth connected with a confirmation tone. Works with any brand of speaker.*Universal switch mode power supply. Input. AC 110V~220V, 50 / 60Hz; Output. DC 12V, 5A 60W. Make sure you get 5 amps minimum as that’s what this amplifier uses.

We replaced our volume controller, removed our receiver input and left it by itself behind the wall, connected the 2 speaker output to the new in wall receiver. It only took less than 15 minutes! Wow, great sound! There could have been a better way for powering, the adapter wire is not long enough to reach the nearest power outlet. We will figure that out. Glad we could bring our ceiling speakers to life! GO FOR IT!

This produces pretty good audio. It powers a set of old bookshelf speakers I have and it sounds really clear. I'm impressed that so few watts gives a pretty loud and clear output from the speakersA few things:1. There is no manual and the instructions in the box are light and sometimes wrong. Example, "Press and Hold the Volume Knob for more than 3 Seconds" The knob is a 'turn to switch on' and it does not depress.It doesn't answer things like which set of screws are right or left to attach the speakers and the board and connectors are labeled + and - but not R or L.2 You can charge a device connected to the USB but only when the switch is on3. The bluetooth can connect to one device at a time. If my wife and I both have a phone with bluetooth, if mine auto connects, she is locked out. She couldn't pair until I realized that even though my phone was in my pocket, it apparently auto paired.4. There is a 1.5KHz hum in my unit when it is connected but not playing anything. It is not loud but it's there. It is a pure tone on my frequency analyzer.5. There were no screws to connect the unit to the box. There were screws for the cover but not to attach the unit to the wall box.For the price, it can be made to work and work acceptably. It will require more than average skills to connect it.
