1. Introduction
The Universal Digital/Analog Audio Converter is a gadget that can convert
Optical, Coaxial and L/R audio signals. With the ability of audio formates
conversion, this gadget can either convert digital audio into analog L/R audio
or convert analog L/R audio into digital audio . If you find yourself limited by
multiple audio formats, why not consider the Universal Digital/Analog Audio
Converter and find out what pure audio sounds like.
2. Applications
