8. Articulator switch (ARTICULATOR)
This function performs demagnetization by using sound sig-
nals.
When a record is played with the articulator set to ON, the
cartridge and step-up transformer are demagnetized, and
thus the expression of fresh sound is brought back.
When the articulator is set to ON, no sound is generated
or the sound becomes remarkably small during playback.
This is the sign that the cartridge is being demagnetized.
If the articulator is set to OFF at this point, the sound sud-
denly becomes loud. Therefore, do not turn up the sound
volume of the control amplifier or the like. It is recommend-
ed to activate the articulator for approximately 30 seconds
before the end of a track of the record.
• OFF
Deactivates the articulator. Select this position under nor-
mal conditions.
• ON
Activates the articulator.
9. Articulator indicator
Turns on when the articulator is activated.
10. Mode switch (MODE)
• STEREO
Is used for stereo playback. Select this position under nor-
mal conditions.
• MONO
Is used for monaural playback.
11. Low cut switch (LOW CUT)
Toggles the low-frequency cutoff function on and off. The
speaker (woofer) fluctuation is restrained. When a warped
record is played.
• OFF
Provides the normal state.
• ON
Cuts low frequencies of 20 Hz or less. (–6 dB/oct)

12. High cut switch (HIGH CUT)
Toggles the high-frequency cutoff function on and off.
• OFF
Provides the normal state.
• ON
Cuts high frequencies of 8 kHz or more. (–6 dB/oct)
13. Gain selection switch (GAIN)
Selects the gain among 36 dB, 38 dB, and 40 dB. The gain
is selectable according to the output voltage of the car-
tridge.
14. Input impedance control (IMPEDANCE)
Controls the input impedance according to your cartridge.
The variable range is from 30 kΩ through 100 kΩ.
15. Input capacitor selection switch
(CAPACITIY)
Selects the input capacitor according to your cartridge. Se-
lectable capacitors are the following: 0 pF/50 pF/100 pF/
150 pF/200 pF/300 pF
16. Cartridge selection switch
(CARTRIDGE)
Selects the input impedance. The selectable positions are
MM, MC low and MC high. Select a position in accordance
with the input impedance specified in the operating instruc-
tions of the cartridge.
