Meter Calibration
The 0dB gain reduction reading may need to be calibrated using the GR Zero Set pot.
The GR Zero Set pot is located through a small hole on the front panel below the UA
diamond logo.
1) Turn the LA-610 on and warm up for 5 minutes.
2) Set the meter knob to the GR position.
3) With the Compressor section (right side) Peal Reduction control full off (CCW) adjust
the GR Zero Set trim pot so the meter reads 0 dB. Turn pot slowly and watch how meter
settles.
