Calibrating the GRAPHI-Q Front Panel Controls after flashing new Firmware
NOTE: Graphi-Q firmware can be updated without losing any of your presets! And it's FREE!
Your Sabine GRAPHI-Q ships from the factory with all front panel controls precisely calibrated for maximum accuracy. However, each time you flash new firmware into your Graphi-Q, it is very important to recalibrate the front panel controls. You may also want to periodically recalibrate to assure the highest degree of front panel control precision.

Calibration is a simple process.
  1. Set all equalizer faders (both channels on a GRQ-3102) to the center detent position.
  2. Rotate the Hi Cut and Threshold knobs (both channels on a GRQ-3102) to the fully clockwise position.
  3. Rotate the Lo Cut, Ratio, and Gain knobs (both channels on GRQ-3102) fully counterclockwise.
  4. Hold down both the Fifth Octave and Set Fixed buttons (use channel B on a GRQ-3102) as you power the unit on. Release the Fifth Octave and Set Fixed buttons when all of the LEDs begin to flash on and off.
  5. TURN THE GRAPHI-Q OFF AND THEN BACK ON (very important).
Note: Holding the buttons in Step 4 too long may reset all FBX filters.
