7555 HD/SD, 9550 3G/HD/SD, and 9550-XA 3G/HD/SD Video Processing Frame Synchronizers
Spread
0 to 50, factory set to 1 LKFS.
Set the Spread from x to x. The Spread indicates how far above and below the Target Level you want
to allow the AGC to go. A typical setting is 1. If, for example, the Target Level is set at -24 LKFS, and the
Spread is set at 1, the AGC will aim to keep the output signal between -25 and -23 LKFS.
Transition Time
0.5 sec to 30 sec, factory set to 3 seconds.
This setting controls how rapidly LevelTrack Loudness Control will make adjustments once it
determines that a change is needed.
Max Atten
0 dB to -12 dB, factory set to -12 bB.
This control sets the maximum amount of attenuation that LevelTrack Loudness Control can use to
reduce audio levels.
Max Gain
0 dB to +12 dB, factory set to 12 bB.
This control sets the maximum amount of gain that LevelTrack Loudness Control can apply to the
input in order to raise audio levels.
Taken as a whole, these controls provide tremendous flexibility in both how LevelTrack Loudness
Control AGC is configured and in how audio is perceived by the listener.
