Features of This Unit
LECUA-WM - LUXMAN Electric Controlled
Ultimate Attenuator - Waiting Matrix
Application of the system to obtain attenuation by combin-
ing 2 fixed resistances connected to this product series has
improved efficiency of the LECUA1000 attenuator used in our
flagship model, C-1000f.
The shortest signaling route has been achieved by the in-
tegrated amplifier circuit thanks to the 3D structure of the
mounting boards.
Controlling LECUA-WM to the level equal to the volume po-
sition detected by a microprocessor has achieved the op-
eration feeling similar to our conventional sliding-type volume
controls.
ODNF - Only Distortion Negative Feedback -
The amplification feedback circuit that has acquired the high-
speed primary slew rate and ultra-high bandwidth by feeding
back only distortion components generated during amplifica-
tion to maintain the pure sound quality of the main-amplifier
that is almost non-feedback.
The newest version, 3.0A, has achieved the low impedance
and high S/N ratio of the transmission circuit by parallelization
of the first and second stages of the amplifier circuit.
In addition, the input stages of the error detection circuit are
parallelized to moderate the frequency characteristic and
noise.
3 parallel push-pull output stages
3 parallel push-pull structure of bipolar transistor.
Pure class A rated output 30W+30W (8).
High-inertia power supply
High-inertia electronic circuit that combines a large-capacity
EI-core-type power transformer with customizable 10,000F
× 4 capacitor blocks.
Parallel speaker relays
This unit is equipped with large type of 2 parallel speaker re-
lays with a low resistance value to reduce the impedance of
the speaker output lines.
Beeline construction
Newly designed beeline construction composes the audio
input signal via the optimally shortest route to the speaker
output.
Selector switch IC
Selector switch IC with high sound quality, which is used in
the top-end control amplifier, C-1000f, improves the separa-
tion and crosstalk performances.
Schottky barrier diode
Application of schottky barrier diode manufactured by Nihon
Inter Electronics Corporation that has less switching noises
and higher conversion efficiency to the DC voltage for the
power supply rectifier circuit.
LUXMAN’s original OFC wires
Our original OFC wires are used in the internal wiring to
achieve smooth signal transmission thanks to the spiral wrap
shielding on each core and the non-plating process on the
core wire.
Round pattern board
After careful consideration of delicate audio signal flow, a
round pattern board has been applied to achieve smooth sig-
nal transmission.
