Burmester 077 Owner's Manual page 33

Level adjust Some pickups show a pretty high level tolerance between the left and right channel. In this
case the preamp 077 is equipped with an automatic level adjust function. This function
measures the channel differences and automatically adjusts them. This requires that your
record player is configured correctly.
How to approach:
Select a moderate volume, household noise level at max.
With the left rotary switch or the navigation buttons ¡ on your remote control select the
menu option PH-A-ADJ.
To activate the adjustment, turn the right rotary switch or use the navigation buttons ¡
on your remote control until the displays shows PH-A-ADJ ON. Now turn the left rotary
switch or use the navigation buttons . The display will show PH-A-ADJ OK?.
¡
Put a standard test record on your record player. The preamp requires a 1kHz-sine-wave
stereo signal. Now lower the pickup on the record. As soon as you hear the measurement-
signal, activate the measurement by pressing the OK button on your remote control.
During the measurement-process the display will show MEASURE... .
If both channel levels are equal, the display will show LEFT = RIGHT, and adjustment is not
necessary.
If the channel levels are different the display will show ADJUST..., and the 077 adjusts the
channel difference. After correctly finishing the adjust-process the display will show ADJ-
COMPLETE.
If the difference between the channels is more than 5dB, the display will show OVERFLOW!
and the adjust-process will abort. In this case you should check your record player and the
connectors for any errors.
If the measured signal is too low, or there is no signal at all, the display will show LOW
SIGNAL. In this case check all connectors. If those are all connected correctly, then slowly
increase the volume.
At any time you can abort the adjust-process with pressing OK on your remote control. The
display will then show ADJUST OFF!.
