1. INTRODUCTION

The Analog to Digital Audio Converter is designed to simultaneously

convert analog audio signals to Coaxial S/PDIF and Toslink Optical with
the added benet of a switchable audio delay of 150 milliseconds.

The digital audio output signal is 2-channel uncompressed LPCM

(Linear Pulse Code Modulation) with a sampling rate of 48 kHz. The
unit supports Optical Fiber and Coaxial cable runs of up to 5 meters

from the device while still providing a reliable and lossless audio signal.
Compact and easy to install, making it incredibly versatile for the

home or ofce use. The unit is the logical choice for Analog to Digital

audio conversion.

2. APPLICATIONS

• Convert an analog audio signal to digital audio

• Integrate an analog audio source into a digital only audio system

• Extend the operating distance of an audio source

3. PACKAGE CONTENTS

• Analog to Digital Audio Converter

• 5V DC Power Adaptor

• Operation Manual

4. SYSTEM REQUIREMENTS

Analog audio source such as a CD player or MP3 Player with RCA
cables and a digital audio device such as a sound bar or AV receiver.

5. FEATURES

• Switchable audio delay function provides a 150 millisecond delay

when outputting audio

• Supports uncompressed 2-channel LPCM (Linear Pulse Code

Modulation) digital audio output

• Supports an output sampling rate of 48 kHz

• Provides electromagnetic noise-free transmission

• Easy installation and operation
