Overview

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-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.
