1. INTRODUCTION
The Stereo Analog to Dual Outputs Digital Converter (ADC) is
designed to convert analog stereo audio to Coaxial and TOSLINK
Optical digital outputs. The digital output is 2 channels uncompressed
LPCM with a sampling rate of 48 kHz. Both Optical and Coaxial cables
connected to the output ports of the unit can run up to 5 meters whilestill providing a reliable and lossless audio signal transmission. The unit
is both compact and easy to install, which makes it a very handy
device, perfect for converting audio signals in the home or workplace.

2. APPLICATIONS• Convert analog audio to digital to connect to optical or coaxial
digital AV receiver input• Convert and distribute an analog audio signal to 2 digital outputs (1Coaxial and 1 Optical)

3. PACKAGE CONTENTS• Stereo Analog to Dual Outputs Digital Converter (ADC)• 5 V DC Power Adaptor• Operation Manual

4. SYSTEM REQUIREMENTS
Analog audio source device such as DVD or CD player and audio
output device such as an amplifier or AV receiver with digital audio
input (Coaxial/Optical).

5. FEATURES• Supports uncompressed output of 2 channels LPCM digital audiosignals• Supports an output sampling rate of 48 kHz• Provides electromagnetic-noise-free transmission• Easy to install and operate16. OPERATION CONTROLS AND FUNCTIONS
