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.
