20 Channel Professional Bluetooth Studio Audio Mixer - DJ Sound Controller, USB MP3 Player, 16 Microphone Jack, 7 Band EQ, 16 BIT Digital FX, 48V Phantom Power, Unpowered (BR-200MX)

Received timely. Large bang for buck if you need a simple mixer and only one monitor mix.Spent hours testing each channel feature; checked every input/output, gain, EQ, monitor out, mute, etc. EVERYTHING worked GREAT and surprisingly clean sound across the board (no pun intended) without any noise issues. Did not test the built-in effects (as I don't need those). I did test the bluetooth/thumb drive USB features, which all worked well and a nice plus to have those options mapped to a single channel for playing any soundtracks.
