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 (waveform drawing

Fig.16-2 EFBL)

(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

• 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.

Notes:
1: Description of the "FM IF Adjustment" is not carried on this

Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.

2: The parts in the FM front end section are prepared in a

complete unit, so you can't obtain each part individually.
