Description
When your rig needs a compact, no-nonsense way to combine microphones and stereo sources into a single stereo bus, the ART MX622 earns its 1U of rack space. It accepts three balanced XLR inputs (switchable between mic and line level) alongside three stereo RCA pairs, giving you enough flexibility to handle a small FOH setup, a broadcast feed, or a recording sub-mix without dragging out a full console.
Each mic/line channel gets its own level control and clip LED so you can dial in gain with confidence, and switchable 15V phantom power keeps condenser mics running clean. On the output side, balanced 1/4-inch TRS mains with master level control pair with dedicated stereo record outputs, so you can send a mix to the PA while tapping a separate feed for archiving or broadcast. A two-band master EQ (±12dB at 100Hz and 10kHz) lets you shape tone across the whole mix, and the mono-send/stereo-return effects loop adds outboard processing without disrupting signal flow.
Internally powered and housing everything in a single rack space, the MX622 is built for install jobs, submixing tasks, and touring racks where reliability and a small footprint matter more than channel count.
