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 amplifier
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.

1 FUNC: 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 identified under this
mode. The frequency indicator will flash 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”.
2 IN: 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.
3 MINUS/PLUS (-/+): To adjust output volume from 0~-60dB or select
in different frequencies.
