for the second channel, or exiting to normal operation.
8.2.5.3. Two Cautions When Using Setup Mode
1.
Do not use turbo during a performance.
It is a setup tool only. If you play audio through the Graphi-
Q while it is in Setup Mode (Manual or Auto), the audio may sound distorted, and FBX filters will set
inappropriately.
2.
Setup works best in a quiet environment.
Because it relaxes its analysis of what constitutes
feedback, Setup mode may cause the Graphi-Q2 to set filters for any sound picked up by a
microphone.
When in doubt, exit
Setup
Mode
and ring out feedback by raising system gain. The results should be
identical, but feedback during setup will be louder.
8.2.5.4. Normal FBX Operation
After resetting FBX filters, if you close the Setup screen, your Graphi-Q will still place FBX filters when
feedback occurs. You can place filters without Setup Mode simply by raising system gain until feedback
occurs.
8.2.6. Crossover Adjustments
The new Graphi-Q2 crossover allows you to divide the input signal of any Graphi-Q2 by frequency range
and send it to the two outputs. Here are a few important protocols when using the crossover:
Input/Output
—GRQ3121 or GRQ3121-S: These are 1x2 units. The A output is for the low frequency band, and the
B output is for the high frequency band.
—GRQ3122 or GRQ3122-S: These are 2x2 units. When using the crossover use only the A channel
input. Engaging the crossover will remove the B channel input from signal processing path. The A output
is for the low frequency band, and the B output is for the high frequency band.
Other processing
—GRQ3121 or GRQ3121-S: These are 1x2 units. All other processing (except the delay) occurs before
the crossover.
—GRQ3122 or GRQ3122-S: These are 2x2 units. When using the crossover the active independent
processing for each channel is maintained.
Using the crossover
Selecting the Crossover button from the main screen of the GRQ2 Remote Software opens the window
shown below. Choose your high and low shoulder frequencies, filter slopes, and filter types as shown.
You may also control gain for each of the low (channel A) and high (channel B). This is the same gain
control found on the Main Screen and the Compressor Screen.
