Compact SPDIF Audio DAC

Measurements: 51 × 41 × 26 mm. Enclosure: Solid black aluminium alloy, precision CNC-machined for tight tolerances, rigidity, and EMI containment. Digital connectivity: Dual SPDIF input — Toslink optical and RCA coaxial — accepting standard stereo PCM streams. Analog outputs: Line-level stereo via RCA L/R pair and 3.5 mm TRS jack. Power: 5 V micro-USB input; included cable; maximum current draw < 100 mA. Labelling: All text and symbols laser-etched directly onto the chassis for permanent readability. Functionality: Fully automatic — no buttons, dip switches, or software dependencies. This DAC targets integrators and audiophiles who value transparency, reliability, and physical resilience over flashy features. Its compact scale and robust build suit retrofitting into existing systems — whether upgrading a decades-old amplifier with digital capability or adding clean audio routing to a hybrid home office/studio. Common applications include extracting audio from HDMI-ARC-equipped TVs (via optical splitter), connecting DAB+ radios with coaxial output to analogue speakers, or serving as a dedicated monitor feed in voiceover booths — all while maintaining galvanic isolation and low-noise performance expected in UK domestic and light commercial environments.
