The MX622 is a versatile mixer combining three balanced microphone or line level inputs with three stereo line inputs into a single stereo line level mix. Each mono balanced XLR input includes fully variable Input gain, Mic/Line switch, Clip indicator, and selectable 15 Volt Phantom power. An external effects loop section provides a mono Send from the three Mic/Line channels to external equipment and stereo Returns with Effects Level and In/Out switch. Three stereo line level inputs are also provided via RCA type jacks with separate Level controls for each stereo pair. Stereo Record output RCA jacks provide full-level signal of the entire mix at all times. Main outputs are stereo balanced ¼” TRS with Master Level and full range Bass/Treble equalization. The built in power supply and single high 19” rack mount format allows for easy installation and reliable operation.
