About the DAC1

The B.M.C. Audio DAC1 is a sophisticated digital-to-analog converter (DAC) that integrates advanced proprietary technologies such as DIGM (Discrete Intelligent Gain Management), CI (Current Injection), LEF (Load Effect Free), and SUPERLINK. It features a unique Superlink interface that transmits master clock, bit clock, left-right clock, and audio data separately via four BNC cables, minimizing jitter and signal degradation by avoiding the usual decode-recode process. The DAC1 includes a global-feedback-free analog section with a CI input for optimal DAC chip interfacing and a LEF output driver that delivers a stable, high-purity output signal without a global feedback loop. It supports multiple digital inputs including coaxial RCA, BNC, Toslink S/PDIF, AES/EBU, USB (up to 32/384 resolution), and four BNC Superlink inputs, as well as analog inputs and outputs (balanced XLR and unbalanced RCA). The volume control is lossless, adjusting amplifier gain directly via DIGM, allowing the DAC1 to function as a full preamplifier in high-end digital systems. It offers switchable digital filters (Flat and Pulse) and oversampling options, with extremely low distortion (THD+N 0.006% digital, 0.0008% preamp) and high signal-to-noise ratios (-110dB digital, -130dB preamp). Dimensions are approximately 43.5 x 7.8 x 32 cm, weighing 8.5 kg. The DAC1 is designed to be modular, with an optional preamplifier module included in some versions, and is optimized to work best within the B.M.C. system ecosystem.
