Designed for supreme tonal quality
LUXMAN's pursuit of the uppermost standards of tonal quality has lead to the creation of the C-900u. Four independent modules in the balanced amplification circuit enable the hot and cold components of the left and right audio signals to be handled independently to suppress unnecessary noise generation. Combining an evolved version 4.0 of our traditional ODNF circuit and a robust power supply has achieved high signal-to-noise performance and improved sound quality without distortion. LUXMAN's original LECUA 1000, a stepped fixed resistance attenuator, is used for the volume adjustment system, a major feature of this new control amplifier. The 88 step range allows for more precise volume adjustment. This product is an appropriate centerpiece for any modern hifi system due to its elegant design, user friendly features, refined tone controls, premium tactile operation, and more.
Multifunctional and user friendly
The multifunctional C-900u has been equipped with user-friendliness, flexibility, and expandability to fully integrate with the listening environment. The clearly visible fluorescent display shows current input source and sound volume. A zoom function on the remote control can expand this 4 times larger. This unit is equipped with a bi-amplifier output mode, in which a balanced output circuit can be used as a 2-channel unbalanced output. An external pre-amplifier input is useful for connection to an AV system and the tone controls are electronically tuned for added tonal quality.
