many different program types, with different reference levels, can be encoded with
full dynamic range and then be decoded to give a uniform loudness level.
4.1.8 Audio Bandwidth
Audio Bandwidth displays the current audio bandwidth of the main channels. This is
dependent on the number of channels being encoded and the data rate.
4.1.9 Encoder Control
Pass Through
Pass Through indicates if the unit is in pass through mode. Pass Through mode
allows the encoder to pass pre-encoded inputs to the main digital output either as a
single bitstream or as part of a multiplexed bitstream. A valid clock source must be
present when this mode is enabled.
Bypass
Bypass is typically used to route the output of a secondary (standby) encoder to the
switched audio output of the primary encoder. To enable this function, the Bypass In
connector of the primary encoder must be linked to the Main Out connector of the
secondary (standby) encoder. Bypass Mode routes the Bypass In source directly to
the Switched Output of the primary encoder. When Bypass Mode is disabled, the
Main Output is routed directly to the Switched Output .
Requested Encoder State
Clicking on the Stop button manually disables the encoding process. Clicking the
Encode button enables encoding to take place, if all required inputs are present.
Activating Time Code Ctrl enables and disables the encoding process based on time
code start and stop values.

Time code control can only be entered on the following conditions:
•
Input Format is set to PCM.
•
Multiplex Mode is disabled.
•
Time code controlled preset recalls are not pending.
