Names and Functions
Front Panel
POWER Switch
This is the switch to turn the power on/off.
POWER Indicator
When the power is turned on, it lights up blue. Right after the power is
turned on, it keeps on blinking until the internal circuit is in a stable
condition and sounds will not come out during that time.
INPUT Changing Switch
The input signal and degauss can be selected by switching the input switch.
- Input Terminal 1 (INPUT1) is selected
- Input Terminal 2 (INPUT2) is selected
- DEGAUSS Let the record play for about 30 seconds. This can degauss the MC cartridge that contains magnetized iron No sounds will come out during this time.
PLAYBACK CURVE Changing Switch
This is the switch that changes the playing equalizer characteristics. The
following three types of playing curves are installed. Switch according to the
type of record you want it to play.
- STEREO: RIAA curve for stereo LP playing
- MONO1: Curve 1 for monaural LP playing (used on a DECCA label and so forth : FFRR)
- MONO2: Curve 2 for monaural LP playing (used on a Columbia label and so forth)
Electric Characteristics of a Playing Equalizer Curve
LOW CUT FILTER Changing Switch
If records with large warps are played, not only the music signals, but
unnecessary ultra-low region signals are inputted into the phono amp and the
vibration board of the low regional speakers will greatly shake back and forth
and this may damage the speakers or distort the sounds. In this case, by
turning this switch on, it can attenuate the ultra-low region signals and
lessen the above phenomenon.
FUNCTION Changing Switch

- MC Select this when using an MC cartridge
Rear Panel
GND Terminal
Connect the earth cable of the analogue disc player with the GND terminal
(Refer to page 9)
INPUT 1,2 Terminals
There are two systems, INPUT1 and INPUT2 for the input terminals. Connect
respective L and R wires from an analogue disc player.
OUTPUT（RCA）Terminal
This connects to the line level’s RCA input terminal (150-250mV) of a pre-
amplifier AUX terminal 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.
AC IN
The power input terminal connects to the power outlet with the attached AC
power cable
