8.3.2.5. Compressor Linking Options for GRQ3122 and GRQ3122-S Models
Just as with any other parameter setting, you may link compressor channels, left or right, within the same
unit, or between multiple units, in either ABS or REL linked networks. The procedure for this is identical
as it is for other parameters.
However, for stereo programs, simply linking compressor settings of the left and right channels to be
identical may not be appropriate. For example, if both channel A and channel B begin to compress when
a peak level exceeds a certain threshold, and the sound engineer intentionally designs his audio
program to have more sound in the left channel, that channel’s sound will be compressed more readily
than the right channel program. Since compression affects sound levels, such a setup will result in a
difference in the balance of left-right channel output levels -- the stereo image will shift.
To preserve channel balance yet still allow compression, Sabine offers another method of linking left and
right channels of GRQ3102 and GRQ3102-S models: True Stereo compression. In True Stereo mode,
both channels are compressed equally if the threshold is exceeded in either channel. There are two
methods by which True Stereo compression can be selected (note that changing compressor link status
by either method will automatically update the status report in the other screen):
1. In the Link Table, enter the letter “S” in the appropriate channel boxes, and click “Apply.”
2. In the Compressor/Limiter screen, you may toggle the box below the CLOSE button to engage either
True Stereo or Dual Mono compressor modes.
True Stereo linking is subject to the following two conditions:
1. It may not be applied to GRQ3121 and GRQ3121-S models. Because these models do not offer two
discrete channel signal paths, True Stereo linking will not apply to such units.
2. In a multiple unit Graphi-Q network, you may NOT apply a True Stereo link from one unit to another,
but only between the left and right channels of a single unit. All the units in a network may have their
L-R channels linked, but each link will be independent of other units.
A GRQ3122 or GRQ3122-S unit with channels linked in True Stereo may not also be part of an ABS or
REL link for compressor values. Of course other parameters may be linked (ABS or REL) independently
of compressor relationships.
8.3.2.6. Crossover Settings
Because crossover settings are unique to a specific set of speakers and their environment, these settings
are not available in the link table. When a crossover is in effect, be careful about linking other filters -
- you may attempt to control a filter that is not appropriate for the frequency response of a given output.
8.3.2.7. Relative Linking and Scale Values
All changes made to cells that are REL LINKED will increment or decrement by an identical number of
steps in the scale of the parameter. This may not always be a linear relationship. For example, changing
the compressor ratio in one REL LINKED cell from 1:1 to 1.4:1 will result in a change in another REL
LINKED cell from 10:1 to 16:1. Both will move up one notch on the scale for compression ratio scale.
8.3.2.8. Loading Memory Presets to Linked Units
If you try to recall and load a stored memory (see Section 8.6) to a unit with cells linked to any other unit,
the screen shown at below will appear.
