Review on 🔊 Bluetooth Home Power Amplifier - 4-Channel 2000 Watt Stereo Receiver with Speaker Selector, AM/FM Radio, USB/SD Card Reader, Karaoke Microphone Input - Home Entertainment System - Pyle P2203ABTU by Robert Gilbert

I've been working with a set of speakers in the 'A' position for some time. Blue Tooth was patchy and cut off beyond 15 feet. I contacted tech support and asked if a bluetooth booster could be added. The answer was no. Added another set of speakers to the B-side, turned on the unit and it clicked loudly a few times and then nothing. Remote speakers "B" and "A" stopped working. I tested the "A" and "B" speakers with another 2-channel receiver I had lying around and they work fine, so the problem isn't with the speakers, it's the unit. technical support contacted; I'm still waiting for an answer, but I bought a Denon receiver. Avoid this if you want to use "A" and "B" speakers or if you want good "Bluetooth" quality.
