Luxman LX-380, Owner'S Manual

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.
