8.2.5.1. Setting FBX Filters with GRAPHI-Q Remote Software. The Remote Software offers an additional
method for setting FBX filters, as well as both Manual Turbo Mode and normal (non-Turbo) FBX setups,
similar to front panel control options. The new software option is called Auto Turbo Mode. See section 6.3.1
for more information about feedback filter and terminology. Also please read Section 6.4 for a more
complete discussion of Turbo Mode.
For Remote Control op-
eration, Manual or Auto
Turbo Modes can only be
accessed by resetting all
FBX filters in one or both
channels (for two channel
units). If you have a 2-
channel unit, and have re-
set filters in both chan-
nels, you will be asked to
select the channel for set-
ting FBX filters in Turbo
Mode. After FBX filters
are reset, the screen at
right will appear:
Once you are familiar with Turbo options, you may move forward by clicking the appropriate selection.
If you are unfamiliar with Turbo Mode operation, click Turbo Help. The following screen will appear:
USING AUTO TURBO: Before selecting AUTO mode, make sure all your microphones are positioned, and
turned up to the approximate correct gain setting for each input, while the master gain on your mixer is turned
down. Raise the master gain slowly (only for the appropriate channel for a 2-channel system) until you hear
the first hint of feedback, then click on AUTO. At this point, the GRAPHI-Q will take over, and slowly raise
its output gain, setting FBX filters sequentially as the gain increases. You will see the filters being set in
the FBX/Parametrics screen (the response curve will change and the actual frequency value of the feedback
will be displayed) and a display of the amount of gain increase. Feedback will occur at a very low volume.
Turbo mode will exit, and the gain will be dropped slightly (for a safety margin), when all fixed filters and the
first dynamic FBX filter have been set, or when Turbo is turned off by clicking on the Cancel Turbo button.
