BCS53 Telephone modules
An analogue subscriber line can be directly connected to a BCS53 module. This module has
a built-in analogue hybrid. When more than two BCS53 modules are on air simultaneously
the program-signal will get coloured. It is possible to have more than two lines off-hook when
they are not on-air. When more than two phone-lines must be on-air simultaneously the
BCS53T modules in combination with a digital hybrid should be used.
GAIN Input-sensitivity control. When the gain is turned CW the
incoming signal will be amplified and the return signal will be
attenuated.
RINGER The LED flashes on an incoming call.
ADJUST R-balance adjust for tuning the internal hybrid for minimal return
signal. This control has to be adjusted so that a minimum of sound
coloration will occur during the telephone conversation.
TEL. ON By pressing the button the phone-line will go on,- or off-hook.
AUX Routes the signal to the AUX-buss.
AUD Routes the signal to the AUD-buss.
PGM Routes the signal to the PGM-buss.
PAN Panorama control. Places the mono-sound in the stereo image.
OVERL. This LED illuminates when the signal in the module is too high,
and in danger of becoming distorted.
PFL Pre-Fader Listening. By pressing this switch the signal will be
audible on the head-phones. The hybrid will automatically go off-
hook.
ON Switch to activate the module. When the ON-lamp lights up the
signal can be heard on the selected busses (AUX, AUD, PGM).
When faderstart is configured the lamp will automatically light up
when the fader is opened.
When the module is activated the PFL function will reset.
FADER With the fader the signal-level can be controlled. The nominal level
is 0dB.
