Description
The heart of the system: control, transparency and absolute refinement
The Classé Delta PRE is the Delta series' reference preamplifier, designed to offer an extremely pure signal path and comprehensive system management. Its fully balanced topology, oversized power supply, and precision relay volume control section ensure exceptional transparency, dynamics, and background silence. Designed for high-end stereo and premium audio-video systems, the Delta PRE combines elegant construction, precision engineering, and an intuitive interface with a high-resolution central display.
Advanced audio architecture and reference-level digital conversion
The digital section integrates a high-performance 32-bit/384 kHz DAC with DSD support up to 11.2 MHz , ensuring precise and natural conversion. The analog circuit operates in fully balanced mode, with selected components and optimized signal paths to reduce noise and distortion. The asynchronous USB-B input, coaxial and optical inputs, as well as XLR and RCA analog inputs, allow complete management of modern and traditional sources, maintaining tonal coherence and detail across the entire frequency range.
Professional integration and total system control
The Delta PRE is designed to integrate seamlessly into advanced installations thanks to Ethernet , RS-232 , IR , DC Trigger and CAN-Bus ports, ideal for home automation systems and professional racks. The mechanical construction with a solid aluminum chassis and passive thermal management ensure operational stability and long life. The graphical interface and dedicated remote control allow simple and precise control of all functions, making the Delta PRE the perfect nerve center for systems with Delta STEREO or Delta MONO power amplifiers.
