AGC Metering (Summary Tab)
The 5 gain reduction meters show AGC activity
from the top down in dB and the AGC crossover
frequencies in use are shown just above the gain
reduction meters. Gating is indicated by bright
yellow outlines around the blue gain-reduction
meters.

AGC (Basic Tab)
There are 5 variable controls here and switches to
set the master band for the sync function and to
bypass the 5-Band AGC section if desired. The
variable controls here are all “global”. That is, they
affect all 5 bands of the AGC simultaneously and
equally. There are also 2 submenu buttons to access
the controls for the low-latency DJ monitor feature.
Multi-Band AGC Menu (Basic Tab)
The first global control is an overall Drive control. It sets the input level to the AGC section, allowing you to adjust
the amount of gain reduction in the entire 5-Band AGC section at once. Increase this control for more compression
and dynamic EQ effect.
Next are overall controls for Gate Master, Attack Offset, Release Offset and Sync. These are described in detail
below. These parameters (except for Sync) can also be individually adjusted for each band in the Advanced tab.
Attack Offset (Attack Time Offset): This global control “trims” the overall attack time of all 5 AGC bands relative
to the individual Attack settings in the Advanced tab. Higher settings (above 0.0) scale the attack of all 5 bands
faster while lower settings (below 0.0) scale them slower.
Faster attack times reduce the transient nature of the input audio, while slower attack times improve it. Extremely
slow attack times must be used with caution because the following limiter stage may be forced to work too hard or
be overloaded. Extremely fast attack times must also be used with caution because they may make the audio sound
too compressed and lifeless, losing too much of its natural dynamic character.
