Description
The MM 623 is a versatile, high quality mixer
designed with the professional in mind. Offering six
microphone inputs, two selectable stereo inputs,
and such features as bus assignment, phantom
power, remote master, Left, Right, and Aux out-
puts, this compact unit is perfectly suited to mod-
ern diverse applications. All inputs and outputs are
electronically balanced. Equalization is performed
by an active, four-band, fixed frequency stereo EQ.
There are three five-segment LED meters moni-
toring each of the main outputs.
Each of the microphone inputs has switchable
phantom power and a 20 dB pad for line level sig-
nals. Channel one has a variable threshold for
ducking all other inputs. The unit offers remote
select of the two stereo inputs. The unit can also
be set as master or slave and all audio and control
buses are linkable. All connections are offered on
pluggable Euro connectors. The MM 623 offers a
multitude of features in one EIA rack space.
