VU Meter calibration
• Route a calibrated 0 VU source to the left Mix insert return. Alternatively, connect a level meter to the console's Mix
bus output, route a tone to the Mix bus and set the master fader to give a reading of 0 VU on the output.
• Deselect the Mix insert sum function.
• Deselect the VU meter –10dB function.
• Locate the VU meter trim pot at the rear of the console. Using a trim tool, or small flat blade screwdriver, adjust the trim
pot to align the left VU meter needle with the 0 VU legend.
• Repeat for the procedure for the right meter.
