with all genresYour
first choice!
ARM+CPLD
as the core audio frameworkThe M2 uses
native decodingasynchronous clock technology from independent RD.
The kernel program took over a year. Its all about the sound quality.
Five TI chips to constitute the whole power supply systemCPLD technologyThe M2 uses high precision clock as the master
device, and uses sampling pulse to force synchronizing the WAV data from ARM.
ARM uses ping-pong buffer to process the data, and its guaranteed the I2S data
wont be interfered by operation or the micro SD card reading. Everything is based
on high precision clocks, which leads to the extremely high fidelity!
The M2 pro uses the only customized
ultra-low jitter crystal oscillator 7050 from CRISTEK as the core componentThe M2 uses CRISTEKs crystal
oscillator of which the lowest phase noise can be -170dB. Its extremely low. The M2 chooses the best
clock crystal oscillator, only to pursue the best sound.
Superb
hardware design from experience accumulationThe main board
is rationally quartered - equally divided into the power supply part, the
digital part, the DAC part and the Amp part. The whole circuit uses high level
water flowing type wiring; the analog part is mirror-symmetric; every port is
in the closest position. Creative
design of built-in Amp positive and negative power supply Class AThe Amp part
occupies 1/4 of the PCB, which is quite a lot among all the portable players on
the market. It uses the structure of the ultra-low distortion Op Amp and 10
discrete transistors. The output uses NPN+PNP geminate transistors. The
quiescent current at last stage of each transistor is 15MA. Ultra linear Class
A biasing.
