GRQ3122 model. In addition, switch positions 8 through 20 will default to front panel settings, until they
are assigned other stored presets. All switch assignments for positions 2 through 7, and any new
assignments for positions 8 and above, will render the front panel controls inoperative, until switch
position #1 is chosen again. For GRQ3121-S and GRQ3122-S models, which do not have front panel
controls, switch position #1 will be disallowed, and switch positions 8 through 20 will remain unassigned
until they are reprogrammed.
Note that initial contact closure switch assignments require the Remote Control software, but once
assigned, presets and memories can be loaded into the Graphi-Q2 simply by choosing the appropriate
switch position. Momentary contact is all that is needed to load a new memory into the Graphi-Q2.
8.6.2.3. Contact closure changes with multiple units
In conditions where multiple Graphi-Qs are wired in parallel from a single contact-closure switch, ground
loop problems can easily arise. To maximize your chances for problem-free operation, make sure all your
audio connections are balanced (including downstream amplifier connections), and that your Graphi-Qs
are placed in the same equipment rack and derive power from the same circuit.
Instead of using a switch wired in parallel, you might consider linking multiple Graphi-Qs with the Link
Table (see section 8.3). Links for all parameters can be made relative or absolute, and you can change
all units that are linked simply by using a contact closure switch wired to one of the units. NOTE: When
using contact closure switching to control multiple units, be sure to allow sufficient time to lapse after
a switch change to allow all affected units to update. Multiple rapid switching may result in only partial
loading of changing parameter values in linked units.
8.6.3. Off Line Editing
From the Graphi-Q2 Welcome Screen (
Section 8.1
) that appears upon launching the program, you may
click on the “Off-Line Edit/Demo” button instead of connecting to actual Graphi-Q. This will open the
software and all of its features, and will look exactly the same as during connected operation, with one
exception: the default mode of the Off-Line setup will display simulated signal levels on the on-screen
metering. You can turn this simulated meter activity off by choosing Option/Turn off meter display from
the top of the Main Remote screen.
Aside from demonstrating the look, feel, and control options of the Remote Software, this feature also
allows you to program and/or edit a Graphi-Q preset off-line. You can create a complete setup, save
it to a hard drive or disk, and load the preset into a Graphi-Q in another location or audio setup. To do
this, simply choose “Save the current preset to a disk file” from the File menu at the top of the screen.
You will be able to name the file and choose its storage location. Single files are designated with a “.grq”
suffix, and are identical to files saved from an on-line Graphi-Q (see
Section 8.6.1.3
). Of course this
means you may also load a file saved externally into the Off-Line Mode, edit the file, save under a
different name, and load into another Graphi-Q.
Note that all Graphi-Q files created Off-Line are treated as a GRQ3122 (or GRQ3122-S) created file, and
will obey the rules described in Section 8.6.1.3 when loaded into a GRQ3121 (or GRQ3121-S) unit.
8.7. ASSIGNING NAMES TO GRAPHI-Q2S
You can assign any 8-character name to all of the Graphi-Qs connected to your computer. You can do
this from either the Network Chain screen (see
Section 8.1
), or by choosing Reference Name Edit at
the bottom of the Options Menu. This latter action will open up a screen that will also display units, serial
numbers, and names, which can be edited.
All assigned unit names will be displayed at the top of the Curve Display field on the Remote Software
main screen. If no name has been chosen, the unit’s serial number will be displayed.
