Coding Mode Option
This option sets the audio coding mode. If the current audio bit-rate is
outside the bit-rate range supported by the new coding mode, the bit-rate
is automatically changed to the lowest value within the supported range.

Selected Option Description
Dual Mono
Dual channel mono audio. Both mono channels are transmitted in the same PID.

This option controls whether the Encoder automatically adjusts the audio
delay to maintain lip sync with the video. If the Encoder is being controlled
via SNMP by a control system that has auto lip sync functionality, then this
should be set to off.

Lip Sync Offset Option
This option is only available if the Auto Lip Sync option is set to On. It
allows a fixed delay to be applied to the audio in addition to the auto lip
sync delay.
