ART MX821S 1RU 8 Channel Mic/Line Mixer

The ART MX821S is a versatile rack mount mixer combining eight independent input channels into a stereo line-level output. Each input channel accepts a balanced XLR microphone input or unbalanced 1/4” TS line-level signal and provides independent level and pan controls. +48 Volt phantom power may be independently selected on each microphone input. A master level control adjusts the signal output to the low-impedance balanced 1/4” TRS jacks. Prefade output (not affected by the master level control) and Aux Bus input RCA jacks allow patching of multiple units when more channels are needed The ART MX821S may be used on stage, in the studio, or for permanent install applications including conference rooms, corporate boardrooms, churches, restaurants, small clubs, health clubs and more. A built-in power supply and single high 19-inch rack mount format allows for easy installation and reliable long-term operation.
