Input you want to optimize on the Tree View Tab. With the line source connected, monitor the Post Gain Meter
and adjust the gain level.
NOTE: Line sources, including video codecs, consumer grade CD players, DVD players and
VCRs, commonly require 10-12 dB of gain to bring their levels up to 0 dBu.
Optimizing Gain for Telco Rx Channels
Optimize telco rx inputs using the same procedure as mic inputs, with the following exceptions. Select Telco Rx on
the Tree View Tab. With someone talking on the phone, monitor the Post-Gain Meter and adjust the gain level.
Optimizing Gain for Telco Tx Channels

Tx on the Tree View Tab. With someone speaking into the microphones routed to the telco tx, monitor the Post
