8.3. LINKING PARAMETERS AND CONTROL WITH THE GRQ-REMOTE SOFT-
WARE
One of the most powerful features of the Graphi-Q2 Remote Software is its capability to control multiple
units from a single central computer. Up to two sets of eight units can be linked via serial cables and
controlled from a single laptop computer.
Control of so many audio
channels can be greatly sim-
plified by linking channels
together, so that multiple
channels may be controlled
by a single keystroke. For
example, if a sound system
is using sets of identical
speakers in acoustically simi-
lar settings, one graphic EQ
curve may be applicable to
all the audio channels, yet
the different speakers may
require different delay set-
tings.
Linking units is accom-
plished via the Link Table,
which can be opened from
the Options menu, or by
pressing F11. The screen
shown at right will open:
Let’s call each unit/channel
combination (e.g., Graphi-Q2
#1, channel B) a “cell.” You
may link cells independently
for all of the displayed parameters; in other words, you can choose to link graphic EQ settings for one
group of cells, and link delay settings for a completely different grouping. There are three available
conditions for linking cells:
·
NO LINK
Parameter settings are independent of all other channels and units. Changing the value
of a parameter for an unlinked cell will not affect any other cell (default condition).
·
ABSOLUTE LINK
Values of parameters for ABSOLUTELY LINKED cells will be copied to the
identical setting. The first cell you choose for your ABSOLUTE LINK group will be the source value
for copying, and will be highlighted with a red color. Once ABSOLUTE LINK is established, all linked
cell settings will change together when ANY of the linked cells is changed.
·
RELATIVE LINK
Value adjustments made to any REL LINKED cell will affect all REL LINKED cells
up or down by equal amounts. Initial differences among cells will be maintained. Since values are
relative, no one cell will act as a master or source value.
Using a combination of letters and numbers (A1, R2, A8, etc.), you may specify up to eight different linked
combinations of cells for each parameter. For example, if you have 8 two channel Graphi-Q2s in your
serial network, you could configure 8 linked groups, each linking together the two channels of each unit.
Or, you could link all the A channels together for all 8 units, the B channels of the first four Graphi-Q2s,
the B channels of units 5 and 6, etc., or any combination up to eight different groups. All cells in the same
linked group must be either ABS LINKED or REL LINKED (e.g., cells labeled A1 and R1).
The links you program will not actually be applied to your Graphi-Q set up until you click APPLY at the
bottom left of the Link Table Screen.
When any parameters for outputs A and B for any Graphi-Q2 unit are linked (either ABS or REL), this
condition will be indicated on all appropriate software screens. One or two lines — REL and ABS
respectively — will connect the appropriate channel indicators, with the main screen link indication
reflecting linking for graphic EQ controls only. See page 24 (top) for an illustration.
