ART MX821 - Eight Channel Mono Microphone/Line Mixer


The ART MX821 is a versatile rack mount mixer combining eight independent input channels into a single mono line level mixed output.

Essential features include: XLR mic and 1/4-inch line inputs, individual level and tone controls, switch-selectable +48 Volt phantom power on each channel. Main output is balanced low impedance. An additional pre-fade output and auxiliary buss input jacks allow patching multiple MX821''s together when more channels are needed.

Built in power supply and single high 19-inch rack mount format allows for easy installation and reliable long term operation.
