Luxman L-505uX - Features of This Unit

2
LECUA-WM - LUXMAN Electric Controlled
Ultimate Attenuator - Waiting Matrix
Mounted with Electrically controlled attenuator for gaining
attenuation amount in combination with the resistance.
By u
sing the dedicated solid state IC to control the
attenuator to the sound volume corresponding to the
angle of the volume nob, the operation texture similar
with conventional slide-type volume is realized.
ODNF - Only Distortion Negative Feedback -
The amplication feedback circuit that has acquired
the high-speed primary slew rate and ultra-
high bandwidth by feeding back only distortion
components generated during amplification to
maintain the pure sound quality of the main-amplier
that is almost non-feedback.
T
he
version, 2.3, has achieved the low impedance
and high S/N ratio of the transmission circuit by
parallelization of the first and second stages of the
amplier circuit.
In a
ddition, the input stages of the error detection
circuit are parallelized to moderate the frequency
characteristic and noise.
Parallel push-pull output stages
Bipolar transistor parallel push-pull structure.
100W+100W (8Ω) rated power output.
High-inertia power supply
High-inertia electronic circuit that combines a large-
capacity EI-core-type power transformer with
customizable 10,000μF × 4 capacitor blocks.
Features of This Unit
Parallel speaker relays
This unit is equipped with large type of 2 parallel
speaker relays 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 separation 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 efciency to
the DC voltage for the power supply rectier 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.
