VACUUM TUBE INTEGRATED AMPLIFIER LX-380
5
6. Subsonic switch (SUBSONIC)
Toggles the ultra-low frequency cutoff function on and off.
OFF: Provides the normal state.
ON: Cuts ultra-low frequencies out of audible range to
prevent ultra-low range noise from adversely affect-
ing audible range. This function is significantly effec-
tive especially when an analog record is warped or a
woofer is shaking owing to ultra-low range vibration.
* When the line straight switch is on, this function will be
“off” and does not function.
7. Mode switch (MODE)
Changes the output mode.
MONO:
Mixes the signals from right and left channels to
provide monaural playback.
STEREO: Provides normal stereophonic playback.
* When the line straight switch is on, this function will be
“stereo” and does not function.
8. Cartridge selection switch
(CARTRIDGE)
Changes the gain level of the equalizer amplifier (amplifier
circuit required to play an analog record).
MC: Selects the MC (moving coil) type cartridge of low
output voltage.
Be aware that the sound volume becomes higher
and unbalanced sound without high frequencies is
generated owing to the impedance when “MC” is
selected during use of the MM type cartridge.
MM: Selects the MM (moving magnet) type cartridge of
high output voltage.
9. Pilot light
Blinks in the time of muting mode when the operation
switch is turned on and lights up when the operation state
is activated afterward. This indicator blinks when the unit is
in the muting mode or when the volume is adjusted with the
remote control.
10. Input selector (INPUT)
Selects an input device from the devices such as a CD/
SACD player and a tuner connected to each input terminal.
This selector has 5 positions consisting of PHONO, LINE-1,
LINE-2, LINE-3, and LINE-4 that correspond to each input
terminal on the rear panel. To select an input source, set
the selector to the position of the source to be played back.
11. Monitor switch (MONITOR)
Selects the monitor input terminal (MONITOR) on the rear
panel.
ON: Enables to play back the data from the recorder.
OFF: Enables to play back the data from the source se-
lected with the input selector.
12. Separate switch (SEPARATE)
Separates the pre-amplifier and main-amplifier each other.
OFF: Uses this unit as a normal integrated amplifier.
ON: Feeds external signals from the MAIN IN terminal on
the rear panel to the main-amplifier section.
When the separate switch is set to ON, the volume control
of this unit cannot adjust the volume of the speakers con-
nected to this unit. Volume adjustment shall be performed
at the input device side such as the control amplifier con-
nected to the MAIN IN terminal.
Entry of direct output into the MAIN IN terminal from a CD
player or other devices that cannot adjust sound volume
constantly provides a full power state and accordingly re-
sults in the risk of speaker damage.
For such input devices, be sure to use a control amplifier
equipped with the sound volume adjustment function as a
relay, generate sound through the speakers with volume
lowered, and adjust the volume to your favorite level. When
arranging the wiring, be sure to turn off the power of this
unit.
* Pre-out terminal (PRE OUT) is kept output regardless of
on/off state of the separate switch.
