FRONT PANEL CALIBRATION POINTS (continued)

VU ADJ

VU ADJUST is for calibration of VU only. It does not affect GAIN REDUCTION readings.

VU ADJ - CALIBRATION PROCEDURE:

•

Set PEAK REDUCTION & LIMITER RESPONSE fully-counterclockwise.

•

Set OUTPUT LEVEL, LIMITER FEEDBACK & STEREO LEVEL RIDE to UNITY.

•

Set IN/BYPASS to BYPASS

•

Allow 10 minutes system warm-up time and 1 minute rest from any peak reduction activity.

•

Inject a +10dBu (2.45V) 1-kHz tone (both channels). Verify level using an external DMM or

suitable meter. If your DMM has a dB function, select that. If not, set to A/C and read

2.45VAC across pins 2&3 of the OUTPUT XLR.

•

Set IN/BYPASS to IN

•

Select +10 on the METER SELECT and observe if the VU METER reads 0dB.

•

Adjust as necessary.

•

+4dBu is factory set to follow the +10dBu calibration. After the above calibration is com-

pleted, the VU METER should read 0dBu when METER SELECT is set to +4 and a 1-kHz tone

of .775v is applied to the input.

STEREO ADJ

STEREO ADJUST (2 each) - In order to achieve proper stereo or multi-channel gain re-

duction action, each channel should be adjusted to be equal. Carefully read the STE-

REO ADJUST calibration procedure to be sure you have a thorough understanding be-

fore attempting calibration. The L2M is fully calibrated for stereo operation before leav-

ing our shop.
