1. INTRODUCTION

The digital audio processor is designed to allow optical or coaxial

LPCM audio source input and convert to different sampling rates

up to 192kHz/24bits. The digital audio processor utilizes DSP engine

instead of software process to prevent distortion. The converted audio

source signal could be output to both optical and coaxial audio

signals simultaneously. The outputs can be connected with amplier

for high quality audio output. Besides, the audio processor support

DSD over PCM (DOP) decodes to PCM in order to further process

the audio signal not only for sampling rate convert but also volume

control. Meanwhile, the pop noise could be reduced when plug in

audio source.

2. APPLICATIONS

• Professional music player

• Amplier producer

• Audio equipment manufacturer

• Studio

3. PACKAGE CONTENTS

• 1×Digital Audio Processor Main Unit

• 1×5 V/2.6 A Power Adaptor

• 1×Operation Manual

4. SYSTEM REQUIREMENTS

Input audio coaxial or optical audio source and output to amplier.

5. FEATURES

• Supports coaxial and optical digital audio input

• Supports Non-LPCM pass through

• Supports coaxial and optical audio output simultaneously

• Supports LPCM input sampling rates up to 192kHz

• Supports to convert sampling rate of input audio source. The

maximum sampling rate up to 192kHz/24 bits

• De-pop function to eliminate pop sound once plug in audio source

• Supports volume control, the minimum volume control could be

reduced to -60dB

• Supports DOP decode to PCM of coaxial and optical audio source

• Supports rmware update via micro USB

• Compact and light weight design

1FUNC: Function key provides modes selections. There are three

modes available.

a. Volume Mode: The default setting sets at volume mode. The

volume could be adjusted once under this mode and the VOL

indicator will illuminate. The mode will automatically switch

back to this mode once switches to input sampling frequency

mode or output sampling frequency mode after four seconds

and not active them.

b. Input Sampling Frequency Detection Mode: The sampling rate

of input audio source will be automatically identied under this

mode. The frequency indicator will ash for input sampling rate

accordingly. If no audio source input, the frequency indicator

will not illuminate.

c. Output Sampling Frequency Adjust Mode: This mode offer input

audio source converts to different output frequencies of 44.1,

48, 88.1, 96,176.4 and 192kHz. If the frequency no needs to

convert, please select “Bypass”.

2IN: The default setting sets at “coaxial in” for input audio source. If

input audio source is optical audio source, please press “IN” key to

switch it.

3MINUS/PLUS (-/+): To adjust output volume from 0~-60dB or select

in different frequencies.
