DATEQ BCS50 user manual
EN
To a BCS53T module an external digital (Telos) hybrid can be connected. A digital hybrid has
a superior trans-hybrid loss than an analogue hybrid. The advantages are a better sound-
quality and the fact that more than two lines can be active at the same time. The exact
amount of possible active lines depend on the quality of the subscriber lines and the trans-
hybrid loss per module.
GAIN
Input sensitivity control. When the gain is turned clockwise the
incoming signal will be amplified and the return signal will be
attenuated.
TEL.
On and off switches to remote control the Telos hybrid.
ON/ OFF
The lamps alternately blink on an incoming call.
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.
