8.2.7. Compressor/Limiter Adjustments
Compressor/limiter controls are located below the EQ curve display on the main Graphi-Q remote screen.
You may adjust settings by clicking (left button) on a virtual knob or control and moving your mouse, or
by clicking with the right mouse button and typing in a value. In the former instance, a pop-up window
will appear to show the chang-
ing parameter value as you
make adjustments.
In addition, you may click the
Compressor button to the
right of the Curve Display,
choose Compressor/Limiter
from the Main Menu, or press
F3. In each case, the screen
shown at right will appear.
Within the Compressor/Limiter screen, you may change values for any of the seven compressor/limiter
parameters (Ratio, Threshold, Gain, Attack, Release, Knee, and Limiter threshold) by clicking in the field
and typing in a value, or clicking in the field and using the scroll bar at the bottom of the screen. For all
parameters except Limiter threshold, you may also use the knobs at the bottom of the main screen. All
parameter value indicators (knob position, numeric indicator, and scroll bar position) will co-vary. In
addition to these indicators, the Compressor/Limiter screen will graphically display the dynamic
relationship of input and output levels. (The front panel gain metering on the Graphi-Q will also reflect
remote control settings.)
For GRQ3122 and GRQ3122-S models, you may choose to have your compressor operate in either True
Stereo mode, or Dual Mono mode. In Dual Mono mode, the compressor for each channel acts
independently. In True Stereo mode, the two channels interact to preserve stereo imaging, and a signal
peak that exceeds the threshold in only one channel will be compressed in both channels. The more
extreme ratio setting of the two channels will be the ratio applied to both signal paths as well.
Note that stereo compression is distinct from linked compressor settings. See
Section 8.3.2.5.

options and how they affect compressor operation.
8.2.8. Digital Delay Adjustments
Digital delay can be set from the main remote screen by three methods:
1.
Using the up/down arrow keys below the delay readout
2.
Right clicking on the delay read-
out, which will allow you to type
and enter a delay value.
3. For a more detailed look, you can
access the Digital Delay Screen
by either selecting Digital Delay
from the Main Menu, hitting the
F4 key, or selecting the Delay
button. The screen shown at right
will appear.
Inside the Delay Screen you may change the delay length by either using the horizontal scroll bar, or
highlighting a field and typing the desired value. Note that all three scales (time, meters, feet) change
together. Front panel delay displays will update when values are changed using the Remote Software.
Caution:
We do not recommend making large changes in delay settings (or loading presets with large
differences in delay settings) when program is playing through your system. Pitch shifting may temporarily
occur as delay is adjusted. You may bypass the delay section without pitch change occurring, but the time
relationship will change. In addition, to avoid “pops and clicks” in the audio signal, digital delay changes are
implemented in steps rather than all at once, and will take a bit longer to be fully realized.
8.2.8.1. Temperature Gauge for Digital Delay
The speed of sound changes as a function of ambient air temperature. Therefore, the delay compensation

You can always right-
click any control knob
to reveal the keyboard
entry window for any
parameter.
For GRQ3122 and
GRQ3122-S models,
this box on the com-
pressor screen allows
the compressor to be
set to True Stereo or
Dual Mono operation.
This option is not avail-
able for the GRQ3121
or GRQ3121-S models.
