The Gefen GTV-DIGAUD-2-AAUD-CO Digital Audio Decoder is a compact, professional-grade solution designed to bridge modern digital audio sources with legacy analog sound systems. It accepts uncompressed digital audio signals (2-channel Linear Pulse Code Modulation, or LPCM) through either Coaxial (S/PDIF) or Optical (TOSLINK) inputs and converts them into standard analog left/right stereo audio signals via RCA-style jacks. This functionality allows users to connect digital equipment, such as DVD or CD players, to older amplifiers or recording decks that lack digital inputs.

The decoder employs an integrated digital interpolation filter and a high-quality Digital-to-Analog Converter (DAC) to ensure clear, high-fidelity sound output. It supports a range of common digital audio sampling rates, including 32, 44.1, 48, and up to 96 kHz, with a 24-bit bitstream for detailed audio reproduction. A simple selector switch on the unit allows users to choose the active digital input source.

Designed for straightforward, plug-and-play operation, the GTV-DIGAUD-2-AAUD-CO is a simple and cost-effective way to preserve existing analog audio equipment. It is important to note that this specific model is designed for 2-channel LPCM and does not support multi-channel formats like Dolby Digital 5.1; sources must have Dolby Digital turned off or set to PCM output for compatibility.
