XUELIN IHIFI770 WM8740 8GB Amplifier Portable HiFi Loseless Music Player
The link for Upgrade Version .
IHIFI770 is an enthusiast music player integrating with high-end manufacturing process and high tone quality.The shell adopts high-cost overall aluminium alloy and molded by cnc numaerial contronl machining . The panel adopts hijg-cost tempered glass , keeping the panel new through for many years without pasting .Combining with the aluminium alloy shell. Representing an unparalled .ice-cold and tough texture .
IHIFI770 palyer primarily attempts to internally install dual-mode output of hardware tuning,with earphone jack of dual output of classic/voice.The intermediate frequency of the voice output is very soft and graceful, while the classic output is elegant and intense ,even perform better in piano and other instruments ,It is available to the hardware compensation for earphone of different styles.
CODEE of the IHIFI770 is the WM8740 decoding chip ,which belongs to second-rate flagship decoding chip of Wolfson.It is a high-performance Hi—Fi level decoding chip commonly used in desktop sound and blue-ray palyer.WolfsonWM8740 decoding chip possesses top-level and highest Signal to Noise Ratio and extremely low Total Harmonic Distortion ,it can restore the most full and most mellow tone .
In order to obtain better tone quality,we screened almost 20 kinds of operational amplifier ,and finally selected AD8656 as the LPE of the whole player ,AD8656 is a kind of precision amplifier, with bandwidth of 28 Mhz,and supports input and output capacity of full power supply swing .this amplifier is featured with low nocise,low distortion and high current output capacity,which can reduce the system noise ,guarantee the fidelity of the radio , and further improve the performance of the audio device.
Master tape level WAV format
- Support FLAC ,APE,ALAC,MP3.etc.The original software algorithm of IHIFI770 directly support original 192K . realizing truly high-definition format play.
Max patent level earphone amplifier .
- IHiFi770 is internally installed with 120mw+120mw max patent level earphone amplifier .Easy drive,high-resistance earphone ,free of headphone amplifier .
Zero background noise.
- Although it oriented to the middle-end market .IHIFI engineers design it with highest standard and rigorous attitude without any carelessness,especially in multiple macromolecule capacitor filtering,repeatedly debug the grounding system and arrangement of the components and parts ,electromagnetic shielding ,ets.It completely restrain the noise of turn on,turn off,music select ,etc.thus the background noise of ihifi770 is lower than other palyers with higher prices ,zero background noise black background .
Tempered glass plane.
- Due to its complex process and high cost,it is only applied in partial high-end mobile phone and pad.Only a few demestic plants master this kind of manfacturing process .IHIFI intially adopts this kind of new material , and promoted this enthusiaset experience into a new level .
Gorgeous touch button,automatically open self-breathing background light ,amzaing and luxurious .
- To achieve optimal experience,during the designing process of IHIFI770, designers and engineers adopted high-cost overall metalcutting seamless shell
- 0.5mm thinner than iphone4 high tone quality,beautiful appearance .
