Adjustment
Since this CD system incorporates the following automatic adjustment
functions, readjustment is not needed when replacing the pickup. Therefore,
different PWBs and pickups can be combined freely.
Each time a disc is changed, these adjustments are performed automatically.
Therefore, playback of each disc can be performed under optimum conditions.
Items adjusted automatically
1) Offset adjustment (The offset voltage between the head amplifier output and
the VREF reference voltage is compensated inside the IC.)
Focus offset adjustment
Tracking offset adjustment
2) Tracking balance adjustment
3) Gain adjustment (The gain is compensated inside the IC so that the loop
gain at the gain crossover frequency will be 0 dB.)
