Safety Cautions
2017.11-HB L-509X

e realisation of a desirable ideal
innovative amplification feedback circuit
ODNF* Version 4.0
Power supply unit featuring
large-capacity components
High stability power supply
The highly stable power supply circuit developed for
the L-509X features a 600 VA EI-core-type power
transformer and independent left and right channel
large capacity blocking capacitors (10,000μFx4 per
channel). This generous custom specification ensures that the power supply unit will not be affected
by any load fluctuation.
the ultimate renement of separates in a single unit.
ODNF Version 4.0 power amplifier block
An integral part of the design of the L-509X is LUXMAN's original ODNF*
amplification feedback circuit, featuring a high-speed primary slew rate,
an ultra-wide bandwidth and a low level of distortion that is achieved by
feeding back only the distorted components of the audio signal from the
output of the amplification circuit. The L-509X is equipped with the latest
Version 4.0 ODNF providing a dramatic enhancement of accuracy in distortion detection due to the triple-paralleled first stage error detection
circuit. Lower impedance and a higher signal to noise ratio have been
achieved due to the paralleled first stage and Darlington equipped second stage amplification circuit. A 3-stage Darlington circuit and a 4-parallel
push-pull structure is used for the output stage, similar to the M-700u
power amplifier. This achieves output at 120W+120W(8Ω) and 220W+
220W(4Ω), enabling the L-509X to drive speakers powerfully with rich
dynamics and full expression.
*ODNF stands for “Only Distortion Negative Feedback”.
Discrete buffer circuit
The L-509X is equipped with a discrete buffer circuit
that is equivalent to the type used in the high-end
LUXMAN C-900u separate amplifier. The clarity of
the audio signal is preserved by this circuit whilst at
the same time the following power amplification stage's driving force is significantly increased.
Prioritizing audio quality in design
The use of crack-resistant peel coat PCBs for the
amplifier boards prevent the quality of audio signals
being adversely affected. This product prioritizes
audio quality in features such as the non-angled,
direct wiring pattern, known as the original LUXMAN’s
Beeline construction, ensuring smooth signal trans-

mission via the optimum shortest route.
Increased damping factor
Large-capacity, low resistance speaker relays are
connected in parallel, enabling loss-less transmission
of the powerful driving force that is generated by the
generous power supply circuit and the amplifier output section of the L-509X. The use of 3.5mm
ling for the amplifier board output and the unit's
damping factor of 370 enables the L-509X to drive
all kinds of speakers accurately.

High quality
e L-509X integrates the features of both a high quality separate amplier
and a high performance integrated amplier into one product.
e goal of creating an ideal integrated amplier, initiated by LUXMAN with the launch of the L-509fSE in 2002,
has now been advanced with the development of the L-509X.
e L-509X integrated amplier is equipped with many desirable features, such as the New LECUA1000
and a discretely congured buer circuit in the output stage of the pre-amplier circuit.
LUXMAN’s ODNF (Only Distortion Negative Feedback) original amplier feedback circuit
and a power supply with independent left and right channel blocking capacitors are intrinsic to this design,
as well as many components used only in high end models, ensuring high-quality audio reproduction.
e design of the L-509X incorporates the cream of LUXMAN's proprietary technologies,
breaking new ground and creating the ultimate expression of “separates in a single unit”.
Chassis structure exemplifies
excellence in function and design
The L-509X features a top panel with a beautiful hairline finish and widened venting to improve heat dissipation. The loop-less chassis structure restricts any
increase in ground impedance. Analog level meters,
illuminated with white LEDs, add to the elegant and

stylish appearance.
An abundance of user-friendly functions
The L-509X is equipped with a high-quality phono
amplifier, compatible with MM and MC cartridges.
This model offers all the functions that a high quality
integrated amplifier should, including bass and treble
tone controls, L /R balance adjustment controlled by
LECUA, pre/power separation function, volume control and headphone output, all integrated into a single unit without compromising sound quality.
Copper alloy terminals
High quality RCA terminals, made of copper alloy,
are used for the LINE-1 inputs of the L-509X, combining the beneficial conductivity of copper and durability of brass. The L-509X features many custommade components befitting a flagship model, such
as the robust power supply and high-grade speaker

terminals that are compatible with Y-connectors.
Gradation cast-iron feet
Thorough vibration countermeasures have been
taken, using cast iron feet with a density gradient
to eliminate resonance. The high grade, aluminium
body remote control is also supplied as standard.

New LECUA*1000 computerized attenuator
New LECUA1000 board
LUXMAN's New LECUA1000 is at the heart of the preamp section and the
volume adjustment control of the L-509X. This computerized attenuator is
integrated with the amplification circuit, a feature integral to the high-end
LUXMAN C-900u control amplifier. LECUA provides an ideal level control
system which allows smooth and fine adjustment of the volume over 88
steps, thereby minimising the deterioration of audio quality at any point of
the volume adjustment range. An advancement of the New LECUA1000 is
the 3D design layout. The attenuator circuit board is directly connected to
the amplification circuit board. Signal routing has been minimized andefficiency has been successfully enhanced. In addition, this design is extremely
resistant to external vibration and eliminates changes in audio quality over
the volume control range. The robust nature of this system ensures longevity
and durability.
*LECUA stands for “Luxman Electronically Controlled Ultimate Attenuator”.
