HE-7 MK3

For who got love on PCM1704UK to order


(Regenerative power supply)

Apply 8 pcs the most real like sound DA chip PCM1704UK

Fully discrete real balanced  current transmition design.

2 pc ultra high frequency 90/98 MHz Accusilicon 318B femtosecond clocks provide synchronous clock for whole unit without PLL up-frequency .

32bit / PCM384K asynchronous transfer Amanero 384 apply the FPGA synchronous clock.

Both USB / HDMI have built in separate isolator and pure class A isolate power supply.

The whole digital circuit built with 1 pc FPGA and 3 pc CPLD programmable chipsets to separate the different configured circuits for avoid interrupt, data process in parallel mode.

Support firmware update to improve on sound quality.

Input signal sampling display.

Support external 10MHz clock input (Default is 50 ohm, 75 ohm can be custom order).

All digital process mode settings accessible by buttons on front  (No need  to open the chassis).
Firmware update port accessible on rear (Update  firmware no need  to open the chassis).
