The DMM 4/2/4
is a digital automatic stereo mixer with four balanced microphone
inputs, two stereo AUX inputs and one stereo recording output and
one stero master output.
A unique and highly effective, intelligent mixing algorithm
automatically allocates gain among the system microphones (NOM
attenuation). A special noise detection function and the
“Noise Sensitive Threshold” algorithm (NST) prevent
accidental activation of input
channels.
The mixing algorithm also includes a “Last Mic On”
function and a “Best Mic On” mode. Each input channel
features low cut as well as LF and HF shelving filters. A dbx®
compressor/limiter is included in the algorithm to provide a
significant improvement in sound quality. Each channel offers
switchable gain (Mic/Line, Mic-Lo/Mic-Hi), switchable phantom
power, and an incremental level control with LED level and peak
hold display. The automixing and ducking functions can be enabled
and disabled for each channel separately.
An expansion connector enables multiple DMM 4/2/4 mixers to be
daisy-chained for larger systems. A rear-panel control I/O port
provides logic in and outputs for controlling external devices.
Also available on the rear side is a RS 232 interface for PC
connectivity.
The DMM 4/2/4 is housed a rugged 19” case with an integrated
power supply.
