1. Introduction

This comprehensive audio converter device allows users to make a wide usewith audio format and interfaces. With three different types of bidirectional
connectors of optical, Coaxial and L/R, this device can convert all three signals
into the desire format. Analog audio signal can be converts into digital output
and digital audio signal can be converts into analog output. Not only so, it
can be perform simultaneously without any signal loss. The audio converter iscompact and elegant, it is easy to set up and friendly use.

2. Applications
 Analog audio signal convert into digital output
 Digital audio signal convert into analog output
 Simultaneously digital and analog audio output
 Digital coaxial to Toslink and Toslink to coaxial conversion
3. Package Contents
 Universal Digital / Analog Audio Converter Power Adaptor
 Operational Manual
4. System Requirements

Input audio source(s) equipments with connection cable(s) and output signal
with connection cables.

5. Features
 Intergrated digital interpolator ﬁlter and Digital-to-Analog Converter (DAC) Integrated Analog –to-Digital Converter (ADC)
 Supports sampling frequencies from 16 to 100kHz
 Provides elelctromagnetic-noise-free transmission
 Easy to install and to operate Compact size with elegant design1
