Introduction
The audio source of next generation - a multifunctional digital stream master with
music play, network access,D/A converter and digital music recording integrated all
together.
The HDM stream player adopts the specialized 32-bit high-performance multimedia
processor and DSP solution.The reference clock system is the industrial grade
digital phase-locked loop(DPLL)system,which effectively reduces clock jitter in
transmission of digital audio signals and achieves an ultra-low Jitter.In addition,by
proprietary technology the audio coding and decoding software can process
32bit/384Khz high bit rate digital master tape audio stream at a high speed and
support the decoding of all kinds of digital audio formats(WAV/WMA/
APE/FLAC/ALAC/ACC).In the future,through firmware upgrading,the device can
support more audio formats.
The audio D/A decoding part adopt the flagship-level decoding chip -WM8741 with
digital filter from Wolfson of the UK.Known as a D/A chip with the best hearing
impression,this chip can produce "simulated feel"sounds more natural than those
produced with traditional digital simulated converters.What's more,the reference
circuit has been specially optimized and calibrated by engineers from the plant of
Wolfson,as well as passing the factory test made by Wolfson.As a result it can
provide SNR of 128dB(monophony) which guarantees a high quality of digital
audio rendering.
The device can be easily adopted into the DAC modes by the screen operation;it
can be used as a high-performance DAC.Connect with your CD device or other
machine which has coaxial cable,optical fiber or even balance digital output directly
it also can be used as high-performance external decoder.
As a device of a relatively perfect function,the HDM Player can also be used as
a network music server.With powerful network processing function,it can support
NAS and can share network resources through WI-FI/LAN.Besides,it can also
be used as an Internet radio.With the built-in channel list,it receives signals from
more than 10,000 digital Internet radio stations from all over the world.
