7. Output selection switch (OUTPUT)
Switches the output between unbalanced output and bal-
anced output. Both outputs cannot be activated at the
same time.
• Unbalanced output (UNBAL)
Outputs a sound signal from LINE-1 and LINE-2.
• Balanced output (BAL)
Outputs a sound signal from BAL LINE-1 and BAL
LINE-2.
8. Articulator switch (ARTICULATOR)
Articulator means tuning, and this function performs
demagnetization by using an internal oscillator.
Pressing this button starts demagnetization and the articu-
lator indicator is displayed. The demagnetization operation
takes approximately 30 seconds. No sound is outputted
during the period.
The transformer attenuator, LECUTA, is demagnetized, and
accordingly, lush sound expression is resuscitated.
Setting the volume position to 9 to 10 demagnetizes the
output transformer thanks to the articulator function.
CAUTION:
After completion of the articulator, the mute function is
canceled. Therefore, be careful with the playback sound
volume.
9. Articulator indicator
The progress level of the articulator is displayed with the
LED.

10. Balance control (BALANCE)
Adjusts the balance of sound volume between right and left
channels. Rotating the control counterclockwise gradually
cuts the volume of the right channel, rotating the control
clockwise gradually cuts the volume of the left channel. This
knob shall be set to the center position under normal condi-
tions, and rotated to make adjustment if necessary.

11. Mode switch (MODE)
Changes the output mode.
MONO
: Mixes the signals from right and left channels.
STEREO : Provides normal stereophonic playback.
12. Low cut switch (LOW CUT)
Toggles the low-frequency cutoff function on and off.
OFF
: Provides the normal state.
ON
: Cuts low frequencies below 30 Hz at a –6 dB/
octave slope.
* This is useful when the woofers of speakers vibrate due to
the warped record during record playback.
13. Line straight switch (LINE STRAIGHT)
Bypasses the tone control circuit and balance control circuit.
OFF : Enables the low-frequency band and high frequency
band to be adjusted with the tone control (TONE
CONTROL) and enables the balance control
(BALANCE) of the right channel and left channel to
be adjusted.
ON
: Bypasses the tone control circuit and balance con-
trol circuit. When the line straight switch is set to
on, the tone control (TONE CONTROL) and balance
control (BALANCE) cannot be adjusted.
14. Balanced input phase inversion switch
(BAL INPUT PHASE)
Switches the phase when the balance input terminal is
used.
The phase shall be corresponding to the phase of the input
device.
NORMAL : ① GROUND
② COLD (–)
③ HOT (+)
: ① GROUND
INVERT
② HOT (+)
③ COLD (–)
