The Optical to L/R Stereo Audio Converter (DAC) with Dolby® Digital
Decoder provides the ideal solution for converting an optical digital audio
signal to analogue stereo audio. With audio sampling rate support up to
48 kHz (Dolby Digital)/96 kHz (LPCM) and I/O data rate support up to 24-
bit, it provides high quality sound conversion. The Dolby Digital Decoder
function guarantees that Dolby digital audio signals are downmixed to
analogue stereo without loss of quality.
This unit is perfect for use in digital recording systems, computer audio
systems or digital mixing consoles and can be powered from any spare
