Features of the
Luxman L-509X
New LECUA1000 —
LUXMAN Electronically Controlled Attenuator 1000 —
New LECUA1000, which is the integration of an amplifier circuit and
a high-precision attenuator by electronically-controlled fixed resistance
switcheovers is mounted. Further fine sound volume adjustable without
deterioration of sound quality from 0 dB through −87 dB
ODNF — Only
Distortion Negative Feedback —
The output section
features LUXMAN’s original distortion-only negative feedback system which
allows for a high speed primary slew rate and ultra-wide audio bandwidth. Only
distortion generated in the amplification process is fed back for cancellation.
This maintains pure, high quality sound reproduction in the main amplifier
section. The latest version, ODNF 4.0 has achieved low impedance and a high
signal to noise ratio for the transmission circuits thanks to the paralleled
first stage and Darlington equipped second stage amplification circuits. Also
the input stage error detection circuits are triple-paralleled to moderate
frequency characteristics and noise
4 parallel push-pull
output stages
4 parallel push-pull
structure of bipolar transistors. Rated output of 120 W+120 W (8Ω), 220 W+220 W
(4Ω)
Peel coat, PCB
A peel coat PCB is
used for the amplifier board to eliminate the dielectric effect of a resist by
using gold plating instead of applying a resist on copper foil with 100μm in
thickness.
Highly stable power
supply
Highly stable power
supply circuit that combines a large-capacity EI-core-type power transformer
with customizable 10,000μF × 8 capacitor bloc
Parallel speaker
relays
This unit is
equipped with 2 large parallel speaker relays with a low resistance value to
reduce the impedance of the speaker output lines.
Beeline construction
LUXMAN’s “Beeline”
construction ensures that the audio signal path takes the optimum shortest
route from input to speaker output.
Selector switch IC
Selector switch IC
of high sound quality, which is used in the top-end control amplifier, C-900u,
improves the separation and crosstalk performances.
Schottky barrier
diodes
By using Schottky
barrier diodes, manufactured by Nihon Inter Electronics Corporation, this unit
achieves higher DC conversion efficiency in the rectifier circuit and much less
switching noise.
Original LUXMAN’s
OFC wiring
Our original
un-plated OFC wiring with spirally wrapped shielding is used for all internal
connections to ensure smooth, pure signal transmission. Especially 3.5 mm2
heavy wire is used between the amplifier board and speaker output board.
Non-angled circuitry
After careful
consideration of the delicate nature of audio signal flow, non-angled circuit
board tracking has been adopted to achieve smooth signal transmission
Phono amplifier
This unit is
equipped with a phono amplifier that is compatible with the MM/MC cartridge to
achieve analog record reproduction in a high-grade level without adding a
dedicated phono amplifier.
Separate function
This unit is
equipped with a separate switch to separate the pre-amplifier and
power-amplifier each other that enables the bi-amp connection adding a
power-amplifier and the coexis tence with an AV system.
Loopless chassis
structure
This unit features a
loop-less chassis, independently constructed to eliminate increases in ground
impedance caused by chassis current.
Copper alloy RCA
terminals
A copper alloy
terminal that has high conductivity equivalent to copper and hardness
equivalent to brass is used for LINE-1 input terminal.
18 mm pitch RCA
terminal
18 mm pitch RCA
input terminals are used (RCA terminals other than LINE-1) to support high
sound quality cables with large connectors
Ventilation
Large-sized
ventilation mounted on the top panel to enhance the heat radiation efficiency
of this unit. The design follows M-900u/70
Cast-iron insulator
For stability and
support, this product features cast iron feet with vibration reducing density
gradient.
Hairline finish for
the top board
Application of
surface treatments such as blasted white for the main unit and sophisticated
hairline finish for the top board
Large type speaker
terminals
Speaker terminals (A
and B systems) of inline layout (with same characteristics for right and left),
which is compatible with Y lugs to enable easy connection with extra-thick
speaker cables.
Headphone output
terminal
This terminal allows
you to casually enjoy sound with headphones
Needle-type meter
This unit is
equipped with needle-type meters lighted with LED, which improves the
visibility in the listening room. High visibility thanks to white illumination.
Aluminum remote
control
The high-grade
remote control, which is encased in aluminum, can control applicable CD/SACD
players as well
