Agc (Advanced Tab) - Omnia .11 Installation And Operation Manual

AGC (Advanced Tab)

6 Sub-Group controls for each AGC band become available in the Advanced tab.
Multi-Band AGC Menu (Advanced Tab)
The Gate_Thresh control allows you to adjust the gate threshold of each band individually.
RTP Level, RTP Speed and Makeup Gain controls do not appear in the Basic tab and must be set individually for
each band.
RTP Level: RTP stands for Return to Platform. What RTP does is return the gain of the AGC to the selected
amount of gain reduction or "platform level" in the absence of audio. This control adjusts the "resting" or "platform"
gain reduction level the AGC will return to when audio pauses or stops (while gated).
The primary purpose of RTP is to prevent the AGC gate from increasing the gain unnecessarily or holding the gain
too low during pauses in audio, which could result in an increase in noise level or unexpected sudden increase in
level when the audio returns.
RTP Speed controls how fast the adjustment to the platform level (set with the RTP Level control above) takes
place – i.e., how long it takes the AGC to move to the target RTP gain reduction level. Range is from "0" (slow) to
11 (fast).
Makeup Gain: Sets the amount of gain to be "filled in" during quieter, softer program passages. The range is "0.0"
(off) to "11" (maximum). This function is also program dependent, and it interacts somewhat with the main Attack
and Release time constants. As the attack/release times are modified, the system also scales the Make-Up Gain time
constants. Use less makeup gain for processing more faithful to the source material; use more makeup gain for
greater loudness and "density" (a more "compressed sound).
The Attack and Release controls in each band sub-group are allow you to set the timing parameters individually
for any desired band.
