PureTools Digital to Analog Audio Converter – S/PDIF or Toslink to Analogue L/R and 3.5mm Audio
The PureTools Digital to Analog Audio Converter is engineered for professional AV environments requiring reliable conversion of digital audio signals to analogue outputs. Designed with dual digital input topology, the unit accepts either coaxial (S/PDIF) or optical (Toslink) sources, outputting uncompressed two-channel analogue audio via RCA L/R and 3.5mm stereo connections. The converter’s architecture supports integration into meeting rooms or control rooms where analogue audio equipment must interface with digital sources. A compact plastic enclosure and micro-USB power input facilitate discreet installation within AV racks or behind displays.

• Digital-to-Analogue Audio Conversion: The converter processes incoming S/PDIF or Toslink digital audio signals, outputting analogue stereo audio through both RCA L/R and 3.5mm connectors for compatibility with a wide range of AV amplifiers and speakers.

• Dual Digital Input Selection: Two selectable digital audio inputs – coaxial (Cinch) and optical (Toslink) – allow flexible integration with various source devices, supporting seamless switching in multi-source AV systems.

• S/PDIF Pass-Through Functionality: The coaxial input features a direct S/PDIF pass-through output, enabling simultaneous digital signal routing to downstream devices without signal degradation or conversion delay.

• High-Resolution Audio Support: The converter supports uncompressed two-channel LPCM or PCM digital audio at sample rates up to 96kHz and 24bit depth, maintaining audio fidelity for professional AV playback requirements.

• Compact Enclosure and Power Input: A lightweight plastic housing and 5V micro-USB power supply enable flexible placement in space-constrained installations, including behind displays or within equipment racks.

Technical Integration for Mixed-Signal AV Systems
The PureTools Digital to Analog Audio Converter addresses the challenge of interfacing digital audio sources with analogue playback equipment in professional AV installations. By supporting both coaxial and optical digital inputs, pass-through functionality, and high-resolution audio formats, the unit enables seamless signal adaptation within hybrid digital-analogue environments.
