C-1000f control amplifier

 Since 1925, Luxman are not about mass produced products designed in Japan, then assembled in China from generic parts. Rather Luxman are designed in Japan, then each part is carefully tested & evaluated. Many parts are custom made for them which really does make these designs special. Apart from the shared Power Supply, the amplifier designs are usually dual mono. Even the transformers are made in Japan to their specification. Luxman select the color paint used on the resistors (to identify value & tolerance) based on extensive listening tests. The chassis are carefully tuned, both vibration and resonance are carefully controlled; they perform like a musical instrument. Finally assembly & testing is all carried out in Japan. The Japanese attention to detail is fantastic, the amplifiers come wrapped in a cloth shroud with elastic underneath, all of the RCA & XLR sockets are protected from oxidation with individual plastic sleeves. Even the power cord is a cut above the normal give-away and actually sounds good. No wonder Luxman achieve a superior sound..

Startling musical clarity is achieved through meticulous engineering and countless hours of fine tuning.

Over thirteen years in design, Luxman’s flagship control amplifier, the C-1000f has a custom attenuator, the LECUA 1000, to maintain a pure musical signal, for any one of its  72 volume settings, only two resistors are in the signal path, for any one channel. The custom made resistors are fine tuned, one by one to maintain purity. Luxman’s most advanced ODNF circuit is employed, release 2.4.

The LECUA 1000* is located next to the amplifier section to achieve a short signal path, minimizing RFI or EMI interferences.

* LECUA is the abbreviation of Luxman Electric Controled Ultimate Attenuator.

To reduce mechanical vibration, all of the components are suspended from the exquisitely machined top-plate. Hence you are looking at the underneath of the chassis.

RJ11 connectors are used for the remote 12 volt DC trigger to power up or down the attached amplifiers.
