ARCHITECT & ENGINEER SPECIFICATIONS
Balanced Input Module (BAL2S)
The BAL2S input mod-
ule shall be a stereo, high-impedance, electronically-balanced
input module. It shall be mutable by higher priority modules
and shall feature an internal PCB jumper to enable or disable
muting from the priority bus system. It shall have a continu-
ously variable ducking control that will enable attenuation of
the input signal from a minimum of
1
0 dB to a maximum of 48
dB relative to the normal unmuted condition. The module shall
have a rapid mute when the mute function is activated and a
gradual fade back from mute when the mute control is deac-
tivated. Gain shall be switch selectable per channel and shall
be 0 dB or +
1
8 dB.
Bridging Input Module (BRG
1
R)
The BRG
1
R input mod-
ule shall have a mono-balanced input and a buffered pseudo-
balanced output that will enable the connection of several
amplifiers to each other in a daisy chain configuration without
creating ground loops between units. It shall have an RCA jack
for both the input and the output connections. The module
shall have a gain/trim control that will allow the gain to be
adjusted plus or minus 5 dB relative to 0 dB nominal gain. 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. It shall have a continuously
variable ducking control that will enable attenuation of the
input signal from a minimum of
1
0 dB to a maximum of 48 dB
relative to the normal unmuted condition and a gradual fade
back from mute when the mute control is deactivated. The
buffered output shall not be mutable. The module shall have a
VOX/gating circuit to control muting of lower priority mod-
ules and an internal gating circuit with controls for threshold
and duration. The module’s output shall be assignable to either
or both of two mixing buses.
6
LINE/MIC Input Module (LMM
1
S)
The LMM
1
S module
shall be a LINE/MIC level input module. Input shall be via
front-mounted screw terminals. It shall have an internal, 24V
DC phantom power supply that is enabled by a PCB jumper.
The module shall have a gain control that will allow gain to be
adjusted from
1
8 dB to 60 dB in MIC position, or from -2 dB
to 40 dB in LINE position. It shall have the ability to mute
lower priority modules and be muted by higher priority mod-
ules. The module shall be able to assume any of four priority
levels. The module shall have an internal gating circuit with
controls for threshold and duration. The module shall have
bass and treble controls with cut and boost of
1
0 dB at
1
00
Hz and
1
0 kHz, respectively. The module’s output shall be
assignable to either or both of two mixing buses.
LINE/MIC Remote Input Module (LMR
1
S)
The LMR
1
S
module shall be a LINE/MIC level input module with remote
volume control capability. Input level control shall be by
remote potentiometer or by direct voltage input (0 – 4.5V
DC). Input shall be via front-mounted screw terminals. The
LMR
1
S shall have an internal, 24V DC phantom power supply
that is enabled by a PCB jumper. The module shall have a gain
control that will allow gain to be adjusted from
1
8 dB to 60
dB in MIC position, or from -2 dB to 40 dB in LINE position.
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 four priority levels. The module shall have an
internal gating circuit with controls for threshold and dura-
tion. It shall have a built-in limiter to control the maximum
output level of the module. The module shall have an LED to
indicate limiter activity. The module shall have bass and treble
controls with cut and boost of
1
0 dB at
1
00 Hz and
1
0 kHz,
respectively. The module’s output shall be assignable to either
or both of two mixing buses.
A Remote Volume Control Panel is included with the module.
The panel shall be wall mountable and shall be able to control
input level from a distance of up to 200 feet using a 2-conduc-
tor cable, or up to 2,000 feet using a 3-conductor shielded
cable.
