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.
