ALIGNMENTS
INITIAL
LOWEST VOLUME ADJUSTMENT
Tune the volume pot to lowest state.
Input a high voltage signal such as 5V from CD input.
Connect a oscilloscope to L channel binding posts.
Observing the oscilloscope, adjust VR301,make the output of
speakers become to the lowest level.
Adjusting VR302,make R channel output become to the lowest level
by same way.
IDLING CURRENT
Level power on for a minimum of 5 minutes.
Connect a DC voltmeter toTP1 and TP2, adjust VR22 for 4mV
reading on voltmeter.
Connect a DC voltmeter toTP3 and TP4, adjust VR12 for 4mV
reading on voltmeter.
ISC CIRCUIT ORIGINAL ADJUSTING
Adjust the pot VR3 to make the DC voltage of the point of TP10
to the same as TP11
