It is powered by a 5V DC power adapter, which is included. You won't believe how compact this package is! The converter has a digital sampling rate of 48 kHz and produces a digital LPCM stereo audio output signal.

It'll take regular stereo audio (from L&R RCA or use the included 3.5mm adapter) and convert it to TOSLINK and Digital Coaxial output, allowing you to run old TVs on new amplifier systems. Youngsters these days! They introduce all these new-fangled customs and vocabularies and whatnot, leaving the older generation unable to communicate with them on any level! Fortunately, Avencore have brought us this Analog to Digital Audio Converter which can get your new and old audio devices working harmoniously. For 4-pole TRRS headphone support please see AVC-C5812. PLEASE NOTE: Adapter only supports 3-pole TRS stereo headphones. Via the included 2RCA Stereo (male) to 3.5mm Stereo (female) adapter cable, this converter accepts either 3.5mm stereo, or 2RCA stereo audio input, with simultaneous TOSLINk and Digital Coaxial (SPDIF) output.

Avencore's A2D Audio Converter converts from a Stereo Analog Audio source to SPDIF Digital Audio outputs.
