LUXMAN C-10X Control Amplifier The LUXMAN C-10X is a flagship control amplifier engineered to make high-end systems feel effortlessly lifelike—delivering a deep, spacious soundstage, exceptionally low noise, and the kind of micro-detail that brings recordings to life. At its core is LUXMAN’s latest LIFES amplifier feedback engine paired with the newest LECUA-EX electronically controlled attenuator, creating a fully balanced, three-dimensionally laid out signal path designed for purity, speed, and realism. Beyond its reference-grade preamp performance, the C-10X is built to serve as the command center of serious audio systems, with flexible output mode selection (unbalanced, balanced, or bi-amp), precise channel/balance tools, and input level offset to keep every source perfectly matched. Add in refined tone controls, a volume-linked loudness function, an external pre-input for AV integration, and a premium aluminum RA-20 remote, and the C-10X becomes a no-compromise preamplifier for listeners who want maximum musical immersion with maximum system control. The LUXMAN C-10X is part of ListenUp's LUXMAN Preamplifier Collection.

The C-10X is a flagship control amplifier (preamplifier) that manages source selection, volume, and system control while providing an extremely low-noise, high-resolution signal to your power amplifier. Does the C-10X support balanced XLR connections? Yes. It provides three balanced XLR input pairs and two balanced XLR output pairs, along with balanced phase switching for system compatibility. How many analog inputs and outputs does the C-10X have? It includes three RCA line input pairs, three XLR balanced input pairs, an external pre-input (RCA L/R), two RCA line output pairs, and two XLR balanced output pairs. What is LECUA-EX, and why does it matter? LECUA-EX is LUXMAN’s electronically controlled attenuator that switches precision resistors rather than using a traditional variable pot, helping preserve clarity and channel balance across the volume range. Can the C-10X be used in a bi-amp system? Yes. It offers an output mode for bi-amp operation and provides per-system level adjustment so you can fine-tune balance between amplifier channels. Does it have tone controls, and can they be bypassed? Yes. It includes bass and treble controls (±8dB) and a Line Straight mode that bypasses tone shaping when you want the most direct signal path. Can I integrate the C-10X with a home theater setup? Yes. The external pre-amplifier input allows direct connection to an AV amplifier’s pre-out for smoother system integration. Does it include trigger connections for powering other gear on/off? Yes. It includes a 12V trigger input and two trigger outputs (12V/0.1A max total) for coordinated power control with compatible components. LUXMAN C-10X Downloads: LUXMAN C-10X Catalog
