The heart of any preamplifier is the volume control. If not executed properly, this key circuit element can cause left/right channel imbalances and introduce subtle but tangible distortions at low volume. For this reason, LUXMAN created our acclaimed LECUA attenuator system. Now we’ve refined the concept with LECUTA, the Luxman Electronically Controlled Ultimate Transformer Attenuator.

The front panel volume control is actually a 34-step rotary switch that triggers 34 relays located totally outside the signal path. The relays activate 34 taps on matching left and right transformers. It is these taps that adjust the volume in carefully calibrated steps. Because transformer cores can influence sound quality, we selected FINEMET® core material from Hitachi Metals, Ltd. This has a unique nanocrystal structure for high saturation flux density, high relative permeability and low core loss. So you’ll enjoy rich, detailed, uncompromising sound even at low volume.

In a design reminiscent of our classic C-1000, the front panel uses the latest precision machining to superpose three thick aluminum layers into one massive, anti-resonant assembly. The aluminum provides a graceful counterpoint to the cabinet, which we cover in natural walnut with a rosewood gloss finish.
