• 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.

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

In case AMP INT (INTERRUPT), SYSTEM PROTECT, FAULT or AMP ERROR has occurred, the unit will
automatically enter to stand-by mode ON/Standby LED willl be flashing as below:-
