Using trickle down technology from the award winning C-1000f control amplifier. The C-900u is a fully balanced design. Three single-ended, plus one dedicated external processor {Home Theater Bypass} and three balanced inputs. Two single-ended and two balanced outputs. A fully balanced design with tone controls is extremely difficult to implement but the Luxman engineers have achieved this to allow music lovers to enjoy all of their music collection. Luxman's latest compact version of the LECUA 1000-WM volume control (LUXMAN Electric Controlled Ultimate Attenuator with Weighting Matrix Technology). as well as the electronic input selector. Luxman’s most advanced ODNF circuit is employed, release 4.0. delivers state-of-the art musical performance.

Simple circuit configuration

LECUA 1000WM unifies the amplifier, volume control functions and power supply in a three dimensional module, resulting in a circuit that is electrically very simple. Long-term reliability is excellent, with performance and sound quality that will remain unchanged also after prolonged use.

LECUA 1000WM uses analog processing

The LECUA 1000WM circuit converts the music signal from a voltage into a current, switches gain by means of switching on the attentuaes, and then reconverts the current into a voltage. The entire process is carried out in the analog domain.

Same ergonomic feel as a conventional high-quality volume control

The counter balanced volume control knob position is detected by a dedicated CPU which in turn selects the current switches for LECUA 1000WM operation. Operating the knob therefore feels exactly the same as with a conventional control, and operation via the remote control is also possible.

Mute and Balance control are also implemented by LECUA 1000WM

The functions of the attenuator and the left/right balance control are covered by the LECUA 1000WM circuit as well, eliminating the need for additional circuit stages. Keeping the configuration simple helps to maintain high performance and sonic purity.

LECUA 1000WM is a radically different volume control principle that eliminates all variable resistors from the signal path and provides top-notch performance and sound quality. Because the music signal is not affected by changes in impedance, high signal-to-noise ratio and low distortion are maintained at any volume control setting.

LECUA 1000WM ensures high S/N ratio and uniform frequency response

Unlike conventional volume controls, LECUA 1000WM does not introduce a change in impedance at any volume setting. Consequently, there is no deterioration of S/N ratio and frequency response remains totally uniform. The benefits are especially apparent at settings that correspond to normal listening levels, because the sound remains perfectly transparent and the tonal quality is not altered in any way.

No more left/right tracking differences or crosstalk

Because LECUA 1000WM is an electronic circuit employing fixed-value resistors, there is virtually no left/right tracking error also at low volume levels. Since channels can be kept separate, crosstalk also does not present a problem

The tone controls might seem like an anachronism in this day and age of minimalism, but they can be remarkably effective in bring to life a less than perfect music collection. We all have music gems in our collection that are sonicly challenging. A lot of the 1980's CDs are quite harsh sounding and the digital glare can be quite fatiguing. Reduce the treble slightly and while the harsh CD is not going to suddenly sound like a reference recording, at least it will now be perfectly listenable. Sit back relax, enjoy the music & forgot about the HiFi. When you want to bypass the tone controls, just engage the Line Straight switch, either from the remote control or from the front panel.

A feature new to Luxman's preamp is the "Pre In" or a Home Theater Bypass for connection to an external Processor.
