4. Voltage Selector (Rear Panel)
Some
models
are
equipped
with
a
voltage
selector
to
conform
with
local
power
supplies,
Be
sure
to
set
this
switch
to
match
the
voltage
of
the
power
supply
in
your
area
before
turning
the
power
switch
on.
Voltage
is
changed
by
sliding
the
groove
in
the
switch
with
a
screwdriver
to
the
right
or
left.
Confirm
that
the
switch
has
been
moved
all

before
turning
the
power
switch
on.
If
there
is
no

on
the
unit
you
have
purchased,
it
can
only
be
used
in
areas
where

been turned on, adjust the semi-fixed resistor R441
ADJUSTMENT PROCEDURES
1. Preparations
a) Place the unit on a level surface, right side up, leaving
at least 15 mm of space at the ventilation openings.
b) There should be no load or signal and the level should
be at minimum.
c) The air should be calm, as moving air can upset the
stability of the gauges.
. Meter zero point
With the power off, align each needle with the 0 mark
using the adjustment screw underneath each meter.
Caution: Do not perform this adjustment immediately
after turning the power off. Perform after the meter
circuit section has discharged.
. Idling current
Remove the cover and, five minutes after the power has

Caution: Do not plug in the power supply cable until all other
connections have been completed and checked,
ef 30 M-5030 ef 4o
back panel
(R541) so that the voltage between Ver-Iro on printed
circuit board NAMA-1780 is 14 mV.
. Meter offset
About five minutes after turning power on and with no
signal present, adjust the semi-fixed resistor R639
(R640) on the printed circuit board NAME-1717 to
align each meter needle with 0.
. Meter level adjustment
a) Apply a 1 kHz input signal to the left (right) channel
INPUT terminal.
b) Adjust the input so that the voltage at the speaker
output terminal (under no load) is 28.28V (29.03
dBV).
c) Adjust R611 (R612) so that the meter reads OdB.
Caution: Item in parentheses are for the right channel.
