Description

The imersiv D-1 is a revolutionary stereo digital-to-analog converter that delivers 28 bits of usable dynamic range, 168 dB of linearity, and an ultra-low -146 dBu (40 nV) self-noise floor. Representing a true paradigm shift in audio design, the D-1 is 100x (40 dB) quieter and more accurate than today's finest DACs, setting a new benchmark in professional conversion.

At the heart of the D-1 is HDR-A (High Dynamic Range Audio) - a multi-path architecture inspired by HDR photography. Just as stacked exposures expand photographic detail, HDR-A stacks multiple audio paths to unlock unprecedented clarity, resolution, and headroom. The result is astonishing purity at the quietest levels and effortless realism across the full spectrum, preserving the spatial cues and timbral detail that define lifelike sound.

Perfected over more than a decade of R&D and validated by Grammy-winning engineers and film composers, the D-1 has been hailed as "a revelation," "like switching from 35mm to IMAX," and "the new industry standard." With +22 dBu of headroom, vanishingly low distortion, and aerospace-grade design, the D-1 is built to serve the most demanding applications in mastering, classical and film scoring, immersive music, and high-fidelity playback.
