The mixer shall be an automatic mixer capable of being daisy-chained, with four gated microphone inputs
and three line inputs. The microphone inputs shall provide 24-V phantom power and a compressor/limiter
separately adjustable for each channel. The device shall be fitted with microphone inputs and a line out-
put on 3-pin XLR connectors and line inputs and recording outputs on RCA jacks. A switchable ducking
function shall cause all other channels to be attenuated while there is activity in the MIC 1 channel. The
mixer shall be fitted with a two-band equalizer (bass and treble) affecting only the main output signal.
