System Configuration ~ Telco Transmit and Receive
Telco Transmit
To open the Telco Transmit configuration window, click the Telco Transmit button on
the Flow Screen. The T button on the Matrix Screen will also open this window.
Mute
Mute mutes the audio being sent down the telephone line to the distant location. The
light on the button illuminates red when Mute is activated. Default is off (unmuted).
NOM
NOM (constant gain) maintains a constant gain level as inputs routed to the output
are gated on and off. The XAP 400 reduces the output level for mics based on the
number of mics gated on and routed to that output. When using NOM over the
expansion bus, only the first four audio channels (O, P, Q, and R) support passing
NOM information.
Enable
NOM
if you want to place this output in a constant gain mode. Default
is on. The green button light illuminates when NOM is enabled.
Gain
Gain establishes the gain level for the Telco output. Select a level between -65 and
20dB. If you select any level below -60dB, the signal will be muted.
Meters
Adjust the gain level using the Meters display as a guide. The
Post Gain
meter, when
enabled, shows the signal level after gain adjustments when a signal is present. The
Tx Output meter, when enabled, shows the signal level after it passes through the
Limiter.
