Adjustment Procedures
1. Alignment of Idling Current
a.
Remove
the
load,
and
connect
a
DC
volt
meter
between
the
check
terminals
A201-1
and
A201-2.
(€
b.
Turn
on
the
power,
and
after
1
minte
preadjust
the
VR201
to
obtain
100mV
on
the
voit
meter.
c.
Then
after
4
minutes
(5
minutes
after
the
power
is
turned
on),
adjust
the
VR201
again
to
obtain
110mV.
2.
Alignment
of
DC
Offset
a.
Connect
a
high
sensitivity
DC
volt
meter
to
the
speaker
terminal.
b.
Adjust
the
VR202
so
that
the
meter
needle
should
show
O+5mV.
3. Alignment of Regulator Voltage
a.
Connect
a
DC
volt
meter
between
the
check
terminals
A202-1
and
A202-2,
and
then
between
the
A202-2
and
A202-3.
b.
Adjust
the
VR203
to
obtain
—56.2+0.1V
between
the
A202-1
and
A202-2.
c.
Adjust
the
VR204
to
obtain
+56.20.1V
between
the
A202-2
and
A202-3.
4.
Alignment
of
BTL
Amp
Voltage
(Fig.
2)
a.
Remove
the
connector
A311
on
the
PB1427-1.
b.
Connect
a
DC
volt
meter
between
the
terminals
A311-1
and
A311-2,
and
then
between
the
A311-2
and
A311-3.
c.
Adjust
the
VR302
to
obtain
—12V+0.5V
between
the
A311-1
and
A311-2.
d.
Adjust
the
VR301
to
obtain
+12V+0.5V
between
the
A311-2
and
A311-3.
5.
Alignment
of
DC
Offset
on
BTL
Connection
é
a.
Set
the
BTL
selector
switch
to
the
“ON”
position
(upper
side)
and
the
input
selector
switch
to
the
‘‘Att-In’’
position
(lower
side).
Also
put
the
input
attenuator
at
the
endmost
counter-clockwise
position
(no
input
ts
i
:
available).
b.
Connect
a
high
sensitivity
DC
volt
meter
to
the
“direct”
input
terminal
of
R-ch.
c.
Adjust
the
VR101
to
obtain
the
OV+5mV
reading
on
the
meter.
Attention
:
Before
alignment,
confirm
that
the
BTL
loads
measuring
instruments
are
not
grounded
to
the
M-OS
itself.
6.
Alignment
of
meters
a.
Put
on
8Q
load
on
the
speaker
terminal.
b.
feed
the
1KHz
signal
to
the
“Att-In”
input,
and
adjust
the
power
output
at
100W
(28.3V)
with
the
volume
€
at
the
max.
position.
Adjust
the
VR402
to
obtain
the
OdB
reading
on
the
meter.
.
Reduce
the
output
by
30dB.
Adjust
the
VR401
to
obtain
~30dB
on
the
meter.
Repeat
the
steps
b~e
to
obtain
the
accurate
indications
on
both
of
the
OdB
and
—30dB
output
levels.
