CHAPTER 2. ADJUSTMENTS
[1] CD Section
•
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.)
* Focus gain adjustment
* Tracking gain adjustment
