Precautions
Installation place
Install this unit in a location where good ventilation and heat
radiation are assured.
Especially, installation of this unit where direct sunlight is
present, where the temperature rises excessively high such
as close to a heater, or where it is humid or dusty may cause
a malfunction even if heat is efficiently released.
Therefore, do not install this unit in such places.
Ventilation holes
The ventilation holes of this product must not be blocked be-
cause this unit is a vacuum tube amplifier and generates con-
siderable heat. If the amplifier is installed on a rack or the like,
secure ample space for cooling and leave the door open. Do
not pile up other things on the amplifier and never put articles
on it. Failure to observe this may cause a malfunction.
Note:
For heat dispersal, do not install this equipment in a confined
space such as a book shelf or similar unit.
* Note
The sound is not generated shortly after
the power supply is turned on.
This amplifier is equipped with a time muting circuit in order
to separate the output circuit. Therefore, no sound will be
generated shortly after the power supply is turned on.
If the volume control is set to a high sound level before the
time muting circuit is canceled, a large sound is suddenly
generated. Please be advised that the volume control shall be
set to a low level at first and adjusted after the sound comes
out of the speakers.
Repair and adjustment
When repairs and adjustments are needed, please consult
with the dealer where you bought the unit.
Cleaning
For cleaning, use a piece of soft cloth to wipe the unit such as
cleaning cloth. When the dirt is hard to remove, use a small
amount of neutral detergent to wipe, and then wipe the unit
with dry cloth. Do not use a solvent like benzine or thinner
because such a substance can damage the exterior.

Precautions in connecting with other
components
When connecting this unit to input devices such as a CD
player, an SACD player, a tuner, and an analog record player,
be sure to turn off the power of this unit and all other con-
nected devices. Failure to observe this may generate a strong
noise resulting in speaker damage or cause a malfunction.
The pin-plug to be inserted in each input terminal of this unit
shall be pushed in firmly. If the grounding terminal is inade-
quately connected, noises including hum may be generated,
resulting in an adverse S/N ratio.

Features of This Unit
LECUTA
LUXMAN Electronically Controlled
Ultimate Transformer Attenuator
The 34-contact transformer type attenuator in which
FINEMET® core is used is switched with paired 34 pieces
of relays. The transformer type attenuator can suppress the
DC resistance generated in series with the signal transmis-
sion line.
FINEMET® manufactured by Hitachi Metals, Ltd. is used
for the core material of the transformer type attenuator like
MQ-300, and therefore, this attenuator features excellence
in the audible frequency characteristic and little change in
sound quality because of low permeability and low core loss
in a wide band.
Minimization and the same length of the connection wires
between the attenuator and relays at all the 34 contacts can
make changes in sound quality due to sound levels minimize.
Vacuum tube amplification circuit
The attenuator driver circuit, tone control circuit, and flat am-
plifier circuit contain a vacuum tube manufactured by JJ Elec-
tronic (Slovakia) (E88CC x 6).
Vacuum tube, E88CC-JJ
E88CC is an SQ (abbreviation of Special Quality) tube whose
characteristics are the same as those of the reliable tube and
features low noise.
Phono equalizer circuit equipped in EXT-IN
The phono equalizer circuit that contains FET and an op-
erational amplifier is used. MM, MC, or impedance can be
selected in accordance with the cartridge to be used. The
capacitor that we recommend can be also selected.
Balanced input circuit
A dedicated super permalloy transformer is equipped in the
input circuit.
PHASE INVERT function
The phase can be switched in accordance with the polarity
of the balanced input or output device to be connected to
this unit.
The phase of the unbalanced output of this unit can also be
switched.
ARTICULATOR function
Clear sound can be reproduced thanks to demagnetization
and tuning of the attenuator transformer.
After the power is turned on, the attenuator transformer is au-
tomatically demagnetized during the mute function activated.
This operation can be conducted even manually with the use
of the ARTICULATOR switch.
A signal is generated by the internal oscillator, this signal is
gradually decreased, and then the attenuator transformer is
demagnetized. If the internal oscillator is not in use, the power
of it is turned off. Therefore, the oscillator does not interfere
with the audio circuit at the normal use.
Eliminating resistance of audio signal line
Elimination of the resistance generated in series with the au-
dio signal line from input to output allows sound quality deg-
radation to be reduced and superior sound reproduction to
be realized. (Resistance is present when phono equalizer is
activated and the LINE STRAIGHT switch is set to off)
Tone control
LUX type tone control circuit is used, which is a classic style.
This unit is also equipped with the bass/treble tone control
function that can select the turnover frequency from three po-
sitions to allow the tone quality to be finely adjusted.
Wooden top cover
A U-shaped wooden top cover is used, which matches with
classic design.
Gloss coating finish with rosewood color is applied on walnut
veneer.
Balance output circuit
A dedicated super permalloy transformer is equipped in the
output circuit.

Operations
Before operation
1. Ensure that the connections are correctly performed.
(Normal playback cannot be achieved with wrong con-
nections of R and L.)
2. When the power is toggled between on and off or the in-
put selector is changed over, set the volume control to the
minimum position in advance.
Playback procedure
1. Press the operation switch to turn on the switch after
ensuring that the volume control is set to the minimum
position.
2. Select a source to be reproduced with the input selector.
3. Adjust the sound level with the volume control.
4. Operate the line straight switch, balance control, tone
control, and the like according to the source to be played
back.
How to operate line straight switch
(LINE STRAIGHT)
The line straight switch is used to play sound with the shortest
signaling route for enhancing the purity of the source selected
with the input selector. When this switch is set to on, the
tone control and balance control are bypassed. When the line
straight switch is set to on, the tone control (BASS, TREBLE)
and balance control (BALANCE) cannot be adjusted.
How to operate tone control
(BASS, TREBLE)
This unit has the tone control function for the low-frequency
and high frequency ranges.
The low-frequency tone control (BASS) is a function to adjust
the tone range lower than the selected one with the selector
switch (FREQUENCY/Hz for low-frequency).
The tone control is set to flat frequency characteristics at
the center position. Rotating the control clockwise makes
the low-frequency range enhanced, and rotating the control
counterclockwise makes the low-frequency range attenuated.
The high-frequency tone control (TREBLE) is a function to
adjust the tone range higher than the selected one with the
selector switch (FREQUENCY/Hz for high-frequency).
The tone control is set to flat frequency characteristics at
the center position. Rotating the control clockwise makes
the high–frequency range enhanced, and rotating the
control counterclockwise makes the high-frequency range
attenuated.
For both the low-frequency and high-frequency ranges, the
right and left channels interlockingly function.
When the line straight switch (LINE STRAIGHT) is set to on,
the bass and treble levels are not changed even if the tone
control is operated.
How to operate balance control
(BALANCE)
The balance control allows users to adjust the balance of
sound volume between right and left channels.
When the balance adjustment is not required, the balance
control is set to the center position.
When the line straight switch (LINE STRAIGHT) is set to on,
the right and left sound volumes cannot be changed even if
the balance control (BALANCE) is operated.
