Review on Pyle Multi Channel Bluetooth Preamplifier Receiver - High-Power 3000 Watt Audio Home Speaker Sound System with Radio, USB, Headphone, AUX, RCA, Dual Microphone with Echo, LED Display, Wireless Streaming P3201BT by Crystal Collins

The remote does not control the input selection and does not control the master volume. The board is useless. No digital surround processing. No sound can be output from the subwoofer and audio out. At the time of writing this article, we have scheduled maintenance to assess the issue. The only EQ we can get working is the treble and bass pots. The master audio output uses a keyed potentiometer instead of a smooth potentiometer. We are considering desoldering and replacing the existing pot. it's either too loud or too quiet with the current mechanical audio volume control. If you have a separate mixer, you're probably fine. THIS DUMB AMP Forces me to add another mixer to the portable rack, adding weight. Bluetooth pairing fails despite showing as connected, forcing us to restart both the amp and the wearable device. Just what you need in the middle of a show. The only thing I think this amp is good for is simply boosting the sound.
