POWER switch
The power supply can be turned on or off by pressing the POWER switch. -
POWER indicator
The POWER indicator lights up blue when the power supply is supplied. -
DC OUT
The DC power supply is supplied from two connectors to the L and R Phono Equalizer units through two DC power junction cables of accessories. L and R are not specified to the two connectors. -
AC IN
Connect the AC power cable of the accessories to the AC INLET of the power supply unit, and plug it in an outlet.
Phono Equalizer Units

Red: When the power turns on, it lights up red with no sounds coming out until the inner circuit is stable.
Blue: When the inner circuit is stable, it lights up blue and sounds will come out.
Purple: When the inner circuit is stable and the FUNCTION switch is at DEGAUSS, it lights up purple with no sounds coming out. -
INPUT Changing Switch
This switch changes the input terminal -
Input Terminal 1 (INPUT1) is selected RCA (unbalanced) / XLR (balanced)
-
Input Terminal 2 (INPUT2) is selected RCA (unbalanced) / XLR (balanced)
-
Input Terminal 3 (INPUT3) is selected RCA (unbalanced) / XLR (balanced)
-
BAL/UNBAL Switch
You can select either RCA (unbalanced) or XLR (balanced) matching the terminalof the phono cable that is to be connected.
Caution
- When using the RCA connector, set the switch to BAL and if there are no hums or noises with the system being used, it is recommended that you continue to use it with the switch at BAL for high sound quaility.
- RCA and XLR cannot be used connecting both of them at the same time
-
FUNCTION Changing Switch
Change according to the type of cartridge used-
MM
Select this when using an MM cartridge.
Select this when using an external MC stepup transformer. -
MC
Select this when using an MC cartridge. -
DEGAUSS
This can degauss the MC cartridge that contains magnetized iron core. Select the input that is not connected to the MC cartridge with the INPUT switch and let the record play for about 30 seconds. No sounds will come out during this time.
Notice -
Demagnetization of the built-in step-up transformer When the power is turned on, select INPUT1, FUNCTION DEGAUSS, and connect a demagnetizer (DG-100) to the RCA terminal of INPUT1 to demagnetize it. At this time, please turn off the connected preamplifier for safety

INPUT 1,2,3 (RCA) Terminals
Use when the phono cable to be connected is an unbalanced RCA type connector. -
INPUT 1,2,3 (XLR) Terminals
Use when the phono cable to be connected is a balanced (XLR) type connector.
Notice
For a balanced connection of the XLR terminal, an applicable phono cable is necessary.- For the XLR terminals, no.1 is GND, no.2 is HOT, and no.3 is COLD.
- Even if the XLR terminal is a balanced connection, if the function is changed to MM, it becomes an unbalanced connection. Caution
- For INPUT1,2,3 do not connect the RCA terminal and XLR terminal at the same time.
- Do not insert a short pin to the RCA terminal when using the XLR terminal.
-
GND Terminal (2 places)
Connect an earth cable from an analogue disc player to one GND terminal from either GND of Lor R.
OUTPUT 1,2 (RCA) Terminals
This is an equalizer output (RCA) terminal of an unbalance. This connects to the line level’s RCA input terminal (150-250mV) of a pre-amplifier AUXterminal or so forth.
Caution
Do not connect to a phono input terminal of a pre-amplifier having a phono amplifier inside. It will go to maximum input and sounds will distort. -
DC IN Connector
The DC power relay cable (from accessories) connects to the power supply.
Caution
Do not plug or unplug the DC IN connector while the power is ON or immediately after the power is OFF.
This may cause malfunction.
