Click the right mouse button over the processor
display. This brings up a menu allowing you to cut,
copy, or paste the processor settings to another
output.
8-band Parametric EQ
With an output selected, click the 8b button to
view the 8-band Parametric EQ controls.
Click the On button to activate the Parametric
EQ for the selected output. The Reset button
returns all the controls to their center positions.
Each band has adjustable gain (±15 dB),
frequency (20 Hz20 kHz), and bandwidth (0.16.0
octaves).
Click the right mouse button over the processor
display. This brings up a menu allowing you to cut,
copy, or paste the processor settings to another
output.
Compress
Click this button to view the Compressor for a
selected input or output. Click an input SELECT
button to select an input. Click the output letter
buttons (A-J) to select an output.
Click the On button to activate the Compressor
for the selected input or output. The Reset button
returns all the controls to their default positions.
The Compressor has five knobs: Attack,
Release, Output, Threshold, and Ratio. Click and
drag on the individual knobs to adjust each
parameter. An analog-style meter indicates the
amount of compression applied in decibels.
Click the right mouse button over the processor
display. This brings up a menu allowing you to cut,
copy, or paste the processor settings to another
channel.
About Compression:
A compressor is used to reduce or limit transient
peaks in a signal. As the input level to the
compressor increases, the output level increases
linearly until the threshold point is reached. After
that point, the output level no longer increases
linearly. Instead, it increases at a reduced rate
determined by the ratio setting.
This compressor features soft-knee
compression. As the input signal level approaches
and crosses the threshold, the compressor
gradually starts compressing. The compression ratio
gradually increases to the required setting
smoothly.
Threshold: This control determines the level around which the
compressor begins to act on the incoming signal. It is calibrated
in decibels, with a range from 60.0 dBFS to 1.0 dBFS.
Attack: This determines how fast the compressor reacts once the
threshold has been exceeded. It is calibrated in milliseconds,
with a range from 0.1 ms to 2500 ms (2.5 seconds) per 20 dB of
gain change.
Release: This determines how fast the compressor turns off once
the signal falls below the threshold. It is calibrated in milliseconds,
with a range from 10 ms to 2500 ms (2.5 seconds) per 20 dB of
gain change.
Ratio: This determines the change in output level. It is a function
of the change in input level (at full compression), once the
threshold has been fully exceeded. It is calibrated in decibels,
with a range from 1.0:1 (off) to 20:1. Thus, if it is set to 10:1, an
increase in input level of 10 dB results in a 1 dB increase in
output level. This assumes the input is above the threshold
level.
Generally, use ratio settings from 1.5:1 to 5.0:1 for compressor
use. Settings from 10:1 to 20:1 are more useful for limiting
purposes. This is because in that range the output level changes
very little as the input increases.
Output: This determines the overall gain of the compressor from
input to output (as measured with the signal below the
threshold level). You can use this control to compensate for the
loss of gain caused by the action of the compressor. It is
calibrated in decibels, with a range from 0 dB (unity) to +20.0
dB.
