8-Channel Microphone Preamp/Mixer

The 8MX2 is an essential companion for any of today's digital multitrack systems. It offers 8 of the proprietary ATI High Voltage mic-preamps in a single rack space, and a stereo mix buss with full monitoring capabilities. Each channel also has a variable threshold limiter as well as full cueing capabilities with metering of level and limiter attenuation.
