A versatile rack mount mixer, the ART MX821S combines eight independent input channels into a stereo line-level output. Each input channel accepts a balanced XLR microphone input or unbalanced 1/4-inch 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-inch 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.
