LECUA (LUXMAN Electric Controlled
Ultimate Attenuator)
An electrically controlled attenuator LECUA, in which at-
tenuation is obtained by combining resistances, is used in
the headphone amplifier unit and analog output unit inde-
pendently to achieve fresh sound.
Built-in headphone amplifier
A high-grade headphone amplifier circuit with discrete cir-
cuit configuration is equipped. The output level can be se-
lected from 2 stages in accordance with the sensitivity of
headphones.
Built-in pre-amplifier circuit
A pre-amplifier circuit equipped with LECUA is embedded
in the analog output.
It is possible to connect the unbalanced or balanced out-
puts to the power amplifier and other directly, so that sound
volume can be controlled.
7-segment LED
The sampling frequency of the digital input and the select-
ed input can be displayed on the monitor with 7-segment
LEDs with a high level of visibility. The attenuation amount
is displayed during sound volume adjustment. The dimmer
function allows the brightness of the LEDs to be selected
from 4 levels.
Original technologies
Our traditional round pattern board, OFC internal wiring, and
original custom-made parts are fully and luxuriously used.
Remote control (RD-24)
Operations can be performed with a compact card-type
remote control.
