The MDA-102 is a dual channel mic-pre with five line level
outputs per channel. As with all System 1000TM modules, the
MDA-102 gains significant power with the addition of
daughterboard accessories. The optional MTX-02 may be used to decode the
M-S microphones at the module, or add the RGC-06 and remote pad for
total control of levels at a remote location. The input clip point of
the MDA-102, like the MDA-101, is +29 dBu at minimum gain. This
makes the module ideal for line level distribution applications that
occasionally require significant gain.
The MDA-102-ra module is a MDA-102PA with remotely controlled
attenuator.
