Hifi360 HF-PLA SD APE Quality WAV FLAC Player Music Player
Multiple Audio Sources Selection
Support high-quality mainstream digital audio formats ,such as WAV,WMA,MP3,FLAC and so on ,enjoying your life.
Panel Process and Function
6MM aluminum wire drawing. Sandblasting panel,3 inches (positive screen ) large monochrome dot matrix LCD screen, all keys are pure aluminum car system oxidation treatment, and uses the symmetrical layout, make the operation more convenient.Full discrete circuit with amp circuit, is your headphone firewall .Gold plate 6.5MM headphone output jack, realizing private music space, dual SD card design and tape read and write indicator lamp.
A group of analog audio output,a group of balanced output,a group of optical fiber output,a coaxial output, all output terminals are used 24K gold plating processing, in order to reduce the output contact resistance, making the perfect sound transmission more real.
The Interface and Operation
Use the 3 inch LCD screen, new humanized design of UI interface, the function display:the main interface integrated volume indicator scroll, the card playing state, the song name ( scrolling), playing time, the current volume, the current directory, the current series of general music number, file type informations and so on.
There are dual operations :full function remote control and panel operation mode.It can support for digital direct directory and songs, multitasking model, in the state of playing it can browse songs, setting the related function.
Special Power Supply Filter
The player has built in power filter,that is composed of inductance, capacitance of the low pass filter circuit elements.It allows 50Hz current through,and cuts the high frequency signal interference, that mades a maximum security to provide a more pure power.
Power rectifier filter
Make value conversion part uses the Motorola ceramic rectifier diodes, other than rectifier diode rectified DC voltage waveform is more suitable for audio circuits.Ordinary level two the waveform is rectangular in shape, ceramic rectifier diode can obtain a smooth waveform of DC voltage, at the same time with the ceramic capacitors (main use for the elimination of the diode switch noise ),can help to show the quality details .
The player is not only use parts of digital capacitances, but also use the ELAN and black steel audio series dedicated capacitor.These capacitances can make the voice to rapid and strong,that is suitable for the performance of modern music. Sound feels very smooth, the sound field is relatively large, sound bottom is very clean.Operational power supply filter uses German Weimaraner, showing a small acoustic impedance, fast speed, low loss tangent foot, acoustic performance of natural balance, color gorgeous, high resolution.Coupling capacitor uses Siemens series.
Audio Decoding and DAC
Audio file decoding use 32 pairs of DSP chip decoding mode, is better than currently available embedded software and solution way , can eliminate high frequency noise due to embedded system and nonstable of the system , when it is single thread ,reading the SD card content decoding, significantly reduce JIETTER of source transmission due to interruption of CPU .
DAC in some parts adopt American CIRRUS top DAC chips: CS4398+CS8406+CS8416.The voice of these DAC chips:Warm and fine, very good voice, full of emotion,good performance of details, high dynamic index, gentle impulse.
