(1) Phono Input Terminal
There are the RCA terminal (unbalanced) and the XLR terminal (balanced) and if they
are connected at the same time, it will be the cause of noises and lossing the sound
quality.
Connect each signal line from your analog disc player to L and R.
* A supported phono cable is needed for a balanced connection of an XLR terminal.
* For the XLR terimal, no.1 is GND, no.2 is HOT, and no.3 is COLD
(2) Phono Output Terminal
Connect to the MM input terminal of the phono amplifier EA-2000EQ

Do not apply testers to the input/output terminals. The transformer’s
performance will deteriorate.
(3) GND Terminal
Connect either the L or R of the earth line coming from the analog disc player to the
GND terminal. Follow the connections diagram for wiring the GND connection cable
(from accessories).
Do not connect the RCA and XLR terminals at the same time to the input.
This unit is designed for a balanced connection due to a 2-core shield line.
Therefore when doing an unbalanced connection due to a 1-core shield line,
it is susceptible to noise effects. Caution is needed especially for high
impedance cartridges.

When the inner circuit is stable, it lights up blue and sounds will come out.
When the inner circuit is stable and the input switch is at MUTE, it lights up purple
with no sounds coming out.
This switch is for changing the played equalizer characteristic. The following three types
of playing curves are contained. Change according to the type of audio record.
STEREO: RIAA curve for stereo LP playing

(7) MM INPUT 1, 2, 3 (RCA) Terminal
Input terminal (RCA) for EA-2000T (MC step-up transformer) and MM cartridge.
(9) OUTPUT (RCA) Terminal
This is an unbalanced equalizer output (RCA) terminal. It connects to the RCA input
terminal of the line level (150-250mＶ) such as AUX terminals of a preamplifier.
(10) OUTPUT (XLR) Terminal
This is a balanced equalizer output (XLR) terminal. It connects to the XLR input
terminal of the line level (150-250mＶ) such as AUX terminals of a preamplifier.
Rear Panel（Left） Rear Panel（Right）
Do not connect to a phono input terminal of a preamplifier that has a phono
amplifier inside. It may go to maximum input and distort the sounds.
Caution
(8) GND Terminal
Follow the connections diagram for wiring the attached GND cable.
An XLR connector is adopted on the OUTPUT for this unit (balanced connection)
The pins are set as shown in the diagram pin = GND pin = HOT pin = COLD.
Some pre-amplifiers are set as pin = GND pin = COLD pin = HOT
and in this case the input signal and output signal are played as an anti-phase.
In order to correct the phase, change the connection so that the wiring of the
XLR connector pin and pin at one side of the balanced cable are inverted.

Trouble Shooting Guide
Trouble Causes 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.
