Review on Bluetooth 5.0 Stereo Audio Amplifier Receiver - 4 Channel, 440W Peak Power Home Theater USB, 🔊 SD, FM - 2 Mic in Echo, RCA, LED - Speaker Selector for Studio, Home - MAMP5 by James Yarbrough

The device is ideal for decorating areas inside or outside the home. I bought it for an outdoor setup and it works great. We currently have two areas of outdoor foosball speakers, some of which are more than 75 feet from the receiver, and power is not an issue. Bluetooth connection with our iPad was quick and easy. 4 separate volume controls, separate bass and treble controls make it very enjoyable. I haven't used a USB or SD card yet, but don't expect any problems with it. Very reliable compact device with excellent sound.
