New Media Technology Omnia ONE Multicast manual Mid Band AGC, Pres Band AGC Presence Band AGC

The release control adjusts how fast the AGC recovers from periods of more gain reduction when the input audio levels fall. Faster release times (higher numbers) result in a more dense sound. Even though the Omnia uses program controlled release algorithms, setting the control for extremely fast release times can result in ‘pumping’.

Gt Thresh (Gate Threshold)

When the input audio falls below a certain level, the gain control action of the AGC stage is “frozen” by the gate. The level at which this freeze, or hold takes place is controlled by the setting of the Gate Threshold control. Higher numbers cause the gate to activate at higher audio levels. In most applications this control should be adjusted to cause gating action to occur when the input audio falls about 20dB below nominal. The action of gate also prevents noise rush up during periods of no audio or during pauses in speech.

RTZ Speed (Return To Zero Speed)

RTZ stands for Return To Zero. What RTZ does is return the gain of the AGC band to the selected amount of gain reduction (See RTZ Level below) in the absence of audio. RTZ speed controls how fast this adjustment takes place – i.e., how long it takes the AGC to move to the target RTZ level.

RTZ Lvl (Return To Zero Level)

This control adjusts the gain level to be achieved by the AGC section during lapses in audio. The primary purpose of RTZ is to prevent the AGC from increasing the gain unnecessarily during lapses in audio, which would result in an increase in noise level.

Low Band Limiter

LFLim Drv (Low Frequency Limiter Drive)

Adjusts the drive level to the individual Limiter band. Used when you desire more or less density in a specific band. These Limiter Drive controls can also be used as secondary dynamic EQ controls after the Drive controls in the AGC Xover.
