MIX843
DESCRIPTION
The MIX843 is an automatic mixer with four gated microphone inputs XLR and three line inputs, a balanced line output XLR and an
unbalanced output for connecting an audio recording device. Each microphone input provides switchable 24-V phantom power for
condenser microphones a separate gate and compressor/limiter. A switchable ducking ("priority") mode reduces the gain of all inputs
for as long as signal is present in MIC channel 1. An attenuation function reduces the output level by approx. 2 dB every time the
number of open microphones doubles. Special rear panel expansion connectors allow you to "daisy-chain" up to ten MIX843 mixers
providing up to forty microphone inputs. The MIX843 automatic mixer features a trhee band eq on the main output and an headphone
output for monitoring.
