7. Only one auto-calibration attempt may be made for each cycling of AC

power to the unit. Once the Line Level Calibration DIP switch has been

placed in the

CAL position, it is necessary to cycle the power before that

DIP switch will be functional again, even if a calibration attempt

was unsuccessful. If one wishes to calibrate again, turn off the

power to the unit and repeat steps 1 through 6.

Reference Level

DIP switch sections 2 and 3 determine the Reference Level, which

adjusts the level of the input signal and the resultant level displayed on

the LED bargraphs. Factory setting is +4 dB. See Figure 1–8 on page 14

for settings.

Bargraph Display Mode

DIP switch sections 4 and 5 determine how peak levels are displayed

for the associated meters on the front panel. There are four possible

settings:

• VU Only,

• VU-PPM Floating Segment,

• PPM Only, and

• PPM-PPM Floating Segment.

The VU Only selection has a VU floating segment when a Peak Hold

value is selected using the Internal 10-Position DIP Switch Module. The

factory default setting is VU-PPM Floating Segment. See Figure 1–8 on

page 14 for settings.
