© Compatibility between SK-6L and SK-
6 Keyboard
KR-4500 use the new type keyboard SK-6L.
Please note that the SK-6L type and SK-6 type
keyboards use incompatible parts each other.
The explanation of differences (or similarities) between
the SK-6L and SK-6, is organized according to three
categories.
Parts A: parts specially for the SK-6L
Parts B: parts used even for the SK-6 but modified
to use for SK-6L
Parts C: parts used even for the SK-6 and used for
SK-6L as it is too
For details, refer to the below.
Now, the procedure to remove or to assemble the key
of SK-6L and SK-6 are different each other.
About the SK-6L, when remove the white key and black
key that is adjacent each other, it is necessory to remove
the white key before the black.
When mount the white key and the black key that is
adjacent each other, it is necessory to mount the black
key before the white.
it is impossible to do with contrary procedure. But, about
the SK-6, either procedure will do.

2. D/A converter MSB adjustments
The KR4500 is equipped with the D/A converter for R
and L channels, each of them should be adjusted
independently.
CAUTION
The adjustments require connections to OUTPUT jacks after
opening the KR-4500 for accessing the main board for
adjustment.
2-1 Remove plugs from the rear panel jacks, if any(e.g.
PHONES,MID)I).
(Opening the panel with plug inserted will result in
damage to PCBs.)
Remove the Music Rack.
2-2 Open the Top Board and then insert the open plugs to
OUTPUT R and L.
(Connecting to only either one of OUTPUTs will cause
to see mixed R and L signals.)
2-3 Press [TONE SELECT] key [2] and the display will
show:
2.MSB ADJUST
Adjust VR-1,2
Sine waves are being applied to the D/A converters. Set
on the KR-4500:
Volume to max. position and Brilliance to the center of
travel range.
2-4 While observing the scope, adjust VR1(L channel)
and VR2(R channel) so that waveforms like the ones
on Fig.1 are obtained.

The ADC is considered good when it reads 0 to 127 as
the control in topic is set min. and max.; if one of three
readings is not in the range O and 127, the control in
topic may be defective; if three readings are out of this
range, ADC is defective.
