Measures
The power does
not turn on
The electric plug is not entirely inserted.
Properly insert the electric
plug to the socket outlet.
Properly insert the AC
power cable to the power
inlet of this unit.
In case the equipment does not operate properly, check out the followings.
If it does not operate properly even after checking the advised points, then remove the
electric plug from the socket outlet and contact the dealer.
No sounds come
out
The signal wire is not entirely inserted.
Insert the signal wire properly.
Sounds do not
come out right
after the power
is on.
This unit uses a vacuum tube.
Sounds do not come out right away until
the inner circuit is stable.
Wait for 1 minute after
turning the power on.
Cannot play
sounds at high
bands
An MM cartridge is used.
Directly connect to the
MM INPUT.
Sounds warp
This unit’s output is connected to the
phono amplifier input terminal of the
pre-amplifier.
Connect to the line level input
terminal (such as AUX) of the
pre-amplifier
When the INPUT
switch is operated,
it makes a clicking
noise
Due to the principle of switching,
it makes a clicking noise to a certain level.
Turn the power switch on this
unit off or operate after using
up all the amplifier’s volume
control.
A hum noise is
heard
The signal wire is not entirely inserted.
The analog disc player and earth line are
disconnected.
There is a power transformer or a motor
of another device nearby
Both the XLR and RCA are connected
to the input terminal.
The phono amp and earth line are
disconnected
The RCA cable connected to the output
terminal is a shield floating type.
The input is an unbalanced connection.
Properly insert the signal wire
Properly connect the earth line
Place it away from the power
transformer and/or the motor.
Connect either one to the
input terminal
Properly connect the earth
line. Try GND connecting
between the phono amplifier
and pre-amplifier although it
is not necessary in general.
Cables that are shield floated
may induce noises. For ones
with an earth line, if the earth
line is connected, there are
times when improvements are
made. If there is no earth line,
use another cable and
connect.
Try the phono cable for a
balanced connection.
