ously variable ducking control that will enable attenuation of
the input signal from a minimum of

0 dB to a maximum of 48
dB relative to the normal unmuted condition and a gradual

tivated. The module shall have a VOX/gating circuit to control
muting of lower priority modules and its internal gating circuit,
with controls for threshold and duration. The module shall

0 dB at
1
00 Hz and
1
0
kHz, respectively. The module’s output shall be assignable to

connector. It shall interface with low-impedance dynamic
microphones. It shall also interface with electret condenser
microphones and shall have an internal 24V DC phantom
power supply to provide the bias supply that is enabled by a
PCB jumper. The module shall have a gain control that will
allow the gain to be adjusted from
1
8 dB to 62 dB. It shall have
the ability to mute lower priority modules and be muted by
higher priority modules. The module shall be able to assume
any of 4 priority levels. The module shall have a VOX/gating cir-
cuit to control muting of lower priority modules and its inter-
nal gating circuit with a threshold control. It shall have a built-
in limiter, with a threshold control, to limit the maximum out-
put level of the module. The module shall have bass and treble
controls with cut only of
1
0 dB at
1
00 Hz and 3 kHz, respec-
tively. The module shall have a voice enhancement control for
improving voice intelligibility. The module’s output shall be
assignable to either or both of two mixing buses.
Microphone Input Module (MIC2X)
The MIC2X module
shall have an electronically-balanced input with XLR connec-
tor. It shall interface with low-impedance dynamic micro-
phones. It shall also interface with electret condenser micro-
phones and shall have an internal 24V DC phantom power
supply to provide the bias supply that is enabled by a PCB
jumper. The module shall have a gain control that will allow the
gain to be adjusted from

8 dB to 62 dB. It shall have the abil-
ity to mute lower priority modules and be muted by higher
priority modules. The module shall be able to assume any of 4
priority levels. The module shall have a VOX/gating circuit to
control muting of lower priority modules and its internal gat-
ing circuit with a threshold control. It shall have a built-in lim-
iter, with a threshold control, to limit the maximum output
