security cover, come standard on the BMX
digital-
8 and -14. Ten preamps come standard on the
other frame sizes. A second five or ten input Mic
Preamp Module can be field installed.
Mic preamps take balanced input signals (from
-65 dBu to -30 dBu) and output ba4 dBu
outputs for direct connection to a Universal Input
module or to outboard processing equipment.
Universal Input Module
This module features two inputs (A and B), each
can come from an analog or a digital source
(source selection is set via a module DIP switch).
DIP switches also set the analog input level or the
digital attenuation. Each input has a fully inde-
pendent parallel logic circuit for remote control
of the module and/or module control of the source
equipment. Each module has independent mic/
