Features of This Unit

LECUA1000 — LUXMAN Electric
Controlled Ultimate Attenuator 1000
Application of the system to obtain attenuation by combining
2 fixed resistances connected in series has improved the effi-
ciency of the LECUA1000 attenuator used in C-1000f.
The shortest signaling route has been achieved by the ampli-
fier circuit thanks to the 3D structure of the mounting boards.
Controlling LECUA1000 to the level equal to the volume po-
sition detected by a microprocessor has achieved the oper-
ation 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-wide bandwidth by feeding
back only distortion components generated during amplifica-
tion for the main amplifier to maintain the pure sound quality
that is almost non-feedback.
With ODNF's latest version 4.0, in the amplification circuit,
the first stage is 4-parallelized and the second stage is con-
nected with Darlington. Due to these improvements, the low
impedance and high S/N ratio of the transmission circuit have
become possible.
In addition, the input stages of the error detection circuit are
3-parallelized to improve distortion and noise.

High-inertia power supply
High-inertia power supply circuit that combines a large-ca-
pacity OI-core-type power transformer with customizable ca-
pacitor blocks.
Schottky barrier diode
In the power supply rectifier circuit, schottky barrier diode
manufactured by Nihon Inter Electronics Corporation that has
less switching noises and higher conversion efficiency to the
DC voltage is applied.
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 processing on the
core wire.
Loopless chassis
The independent construction of a loopless chassis structure
eliminates the rise of increased ground impedance caused by
chassis current.
AC inlet
This inlet enables the connection with an external power ca-
ble.
