ARCHITECT & ENGINEER SPECIFICATIONS (cont.)
Transformer-Balanced Input Module (TBL
1
S)
The
TBL
1
S input module shall be a transformer-isolated, line-level,
balanced input module. The module shall have a pluggable 3-
pin screw terminal input barrier strip connector to make the
input connection. The module shall have a jumper selectable
input impedance of 600 ohms or
1
0k ohms. The module shall
have a gain/trim control that will allow the gain to be adjusted
from -
11
dB to +
1
9 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 circuit to control muting
of lower priority modules and its internal gating circuit with
controls for threshold and duration. It shall have a continuous-
ly variable ducking control that will enable attenuation of the
input signal from a minimum of -
1
0 dB to a maximum of -72
dB relative to the normal unmuted condition and a gradual
fade back from mute when the mute or gate control is deac-
tivated. The module’s output shall be assignable to either or
both of two mixing buses.
Telephone Input Module (TEL
1
S)
The TEL
1
S module
shall have a transformer-isolated, balanced input and configu-
ration jumpers that will allow it to interface with both wet and
dry loop telephone systems. In the dry loop mode, this mod-
ule shall allow connections to page port systems. In the wet
mode of operation, it shall allow connections to both ground
start and loop start telephone systems. The module shall have
a 6-pin screw terminal input barrier strip connector to make
the input connection. The module shall provide for the con-
nection of an external talk-battery power supply of 48V DC.
The module shall have a gain control that will allow the gain
to be adjusted from 0 dB to 30 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 priori-
ty levels. 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. It shall have a built-
in limiter, with a threshold control, to limit the maximum out-
put level of the module. The module’s output shall be assigna-
ble to either or both of two mixing buses.
Tone Generator Input Module (TNG
1
S)
The TNG
1
S
input module shall be a multiple tone generator input module.
The module shall have a 5-pin screw terminal input barrier
strip connector to make the trigger connections. The module
shall include 8 tones: 5
1
2 Hz burst/steady, slow whoop, siren,
mechanical bell, Klaxon, night ringer, double chime, and door-
bell tones. The module shall permit 4 of the 8 tones to be trig-
gered. Momentary and continuous playback modes shall be
available. The module shall have a level control. It shall have the
ability to mute lower priority modules and be muted by high-
er priority modules. The module shall be able to assume any
of 4 priority levels. The module shall have a gradual fade back
from mute when the mute control is deactivated. The mod-
ule’s output shall be assignable to either or both of two mix-
ing buses.
