The Luxman C-10X Control Amplifier is equipped with Luxman's new LIFES (Luxman Integrated Feedback Engine System) amplifier feedback engine and the latest version of the original electronically controlled attenuator, LECUA-EX (Luxman Electronically Controlled Ultimate Attenuator-Excellent eXperience) technologies developed to lead LUXMAN into the next century.
LECUA-EX — Luxman Electronically Controlled Ultimate Attenuator-Excellent eXperience
Luxman's unique sound volume adjustment mechanism LECUA, that is the integration of a high precision attenuator and an amplifier circuitry, is now integrated with a heavy rotation mechanism which offers excellent control feeling and employed here as LECUA-EX. Electrically controlled fixed resistance switching enables fine sound volume adjustments from 0 dB through –95.5 dB with no deterioration in sound quality over the full range of the volume control.
LIFES — Luxman Integrated Feedback Engine System
ODNF, Luxman’s original amplification feedback circuitry, has been renewed, and LIFES is incorporated right at the heart of this amplifier, developing a richer sound quality.
Adopting a dual FET (Field-Effect Transistor) into the input section of the sub amplifier, which detects any distortion in the audio signal, and dual transistors in the cascade circuit and current mirror circuit, sound quality has been improved throughout the amplification circuit with a transparent sound quality comparable a nonfeedback equipped amplifier and excellent high frequency characteristics.
Highly Stable Power Supply
The unit’s highly stable power supply circuitry features a large capacity CI-core-type power transformer with 7 custom designed 3,300 μF blocking capacitors.
Schottky Barrier Diodes
By using Schottky diodes, manufactured by KYOCERA Corporation, this unit achieves very high DC conversion efficiency in the power rectifier circuitry and much less switching noise.
LUXMAN’s Original OFC Wiring
Our original OFC cable, with non-plated core wire, is used for internal wiring to achieve smooth signal transmission.
Loopless Chassis Structure
This unit features a loop-less chassis, independently constructed to eliminate increases in ground impedance due to chassis current.
