The D-1 DAC — Multi-Path High-Dynamic-Range Audio

Welcome to the next evolution in digital conversion. The imersiv D-1 DAC delivers an astonishing 28 bits of ISO-free dynamic range and linearity, thanks to our breakthrough HDR-A® (High Dynamic Range Audio) multi-path architecture.

Why HDR-A® Matters

HDR-A® is like HDR in photography—stacking multiple exposures. In audio, it stacks paths to dramatically extend dynamic range and reduce noise:
Dual DAC paths: one spans 90?dB, the other 100?dB—combined they yield 180?dB total range
Achieves ultra-low 40?nV broadband noise—100× quieter than top DACs
Sustains +22?dBu (10?Vrms) headroom without raising noise, preserving pristine clarity
The result? Unprecedented purity, detail, and depth across the entire musical spectrum.

Pro-Engineered Precision

Trusted and prized by over 40 Grammy-winning engineers and film composers, the D-1 consistently earns acclaim:
"A revelation… I went into shock… the clarity is incredible" – Pro Users
From quiet nuances to dynamic crescendos, enjoy unmatched fidelity, accuracy, and spatial realism.
