TAS5753MD Evaluation Module

The AGL crossover configuration has two operating modes that can
be selected on the top of the main plot:
In basic mode, the crossover frequencies are ganged for left and
right channels, and the filters are configured so cutoff frequencies for
lowpass, bandpass, and highpass filter are matched.
In advanced mode, the user can modify these parameters
individually as well as have a different configuration for left and right
channels for the stereo device.

An

Input/Output

chart is available to easily configure the threshold

levels for each band. Drag and select each threshold and fine tune
the desired threshold level by controlling the levels in the lower part
of the window. Modify the

Softening

parameter to configure the

sharpness of the compression knee of the AGL.

Attack and release parameters are available for AGL tuning:

Attack Rate:

This parameter sets the rate of the attack over the

output signal when it is greater than the desired threshold level. This
parameter acts fast enough to avoid apparent clipping before
engaging.

Release Rate:

When the threshold is raised, this parameter reflects

the release rate of the compressed signal.
