When using the IFB100, this identifier is used to remotely control one specific unit out of the entire group. This
information is also useful in Post to identify the unit since it is recorded in the BWF metadata.

IN
Side chain selection. This parameter selects the audio used to control the
dynamics, specifically it selects the audio feed to the dynamics peak detector.
The options are:
•
HFB
: Input audio to the mic high-passed
•
LP2
: Input audio to the mic low passed more
•
LP1
: Input audio to the mic low passed
•
IN
: Input audio to the mic
Note that this selection does not change the audio that is being processed by the
dynamics, rather it changes the audio signal used to determine the level or
"loudness" of the audio.

3.0:1
Compressor ratio. Sets the compressor ratio i.e. 2.0:1 means for every 1 dB
above the compressor threshold the gain will be reduced 2 dB
