1. Introduction
The Universal Digital/Analog Audio Converter with Dolby Digital Decoder is a
gadget that can convert Optical, Coaxial and L/R audio signals with output
sound guarranty. With the ability to convert digital signals into analog and
analog signals into digital, this gadget supports the simultaneous conversion
of audio formats so when you are converting Optical into L/R audio you
can also convert it into Coaxial and enjoy it without pop sound or suddend
disappear. Therefore, if you find yourself limited by multiple audio formats,
why not consider the Universal Digital/Analog Audio Converter with Dolby
Digital Decoder and find out what pure audio sounds like.
