Automatic Gain Limiting (AGL)

The AGL scheme has two AGL blocks. There is one ganged AGL for the high-band left/right channels and one

AGL for the low-band left/right channels.

The AGL input/output diagram is shown in Figure 45.

Professional-quality dynamic range compression automatically adjusts volume to flatten volume level.

• Each AGL has adjustable threshold levels.

• Programmable attack and release rate

• Transparent compression: compressors can attack fast enough to avoid apparent clipping before engaging,

and decay times can be set slow enough to avoid pumping.
