ART MX624 6-Channel Rackmount Zone Mixer

The MX624 is a six-channel mixer with two stereo zone outputs.

Each channel has stereo RCA line inputs, and channel 6 also has an 1/8” stereo input on the front panel. Channels 1, 2, and 3 also have XLR microphone inputs with switchable phantom power and 20 dB pads.

Channel 1 also has a switchable ducking feature that will reduce the volume of the other channels when signal is detected at the microphone input, so announcements can be heard clearly over background music.

All channels have independent level controls and can be assigned to either or both zones. Each zone has a level control, 2-band EQ, and balanced 1/4” outputs.

The MX624 is ideal for sharing multiple mics and playback sources between two spaces.

General Features:

• Six stereo input channels with individual level controls
• Balanced mono microphone XLRs available on the first three channels

• Full +48V low-noise phantom power independently switchable for each mic input
