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.
