RCA 75 Ohm coaxial audio input (0.5VPP @ 75 Ohm) .
External 10MHz clock input (0.3VPP -3VPP @ 50 Ohm)
USB audio input?USB2.0/USB3.0)
UPDATE PORT 10 pins port
To connect the Altera Blaster and proceed with an FPGA firmware update from Windows, using the Altera programming software. These updates are meant for upgrading the functionality and/or sound quality .
AES/EBU output connector?5VPP @ 110 Ohm)
S/PDIF OUT STD
Standard coaxial output connector, with built-in silver wire isolation transformer. (0.5VPP @ 75 Ohm
S/PDIF OUT ACSS
Output using current transmission technology over coaxial 0.5VPP @ 75 Ohm
This output applies the 2nd generation coaxial ACSS technology, which offers even further reduced signal degradation and better sound quality over a coaxial cable .
IIS signal over HDMI output (3.3V LVDS @ 110 Ohm). It only can work with DACs with an HDMI input supporting I2S audio signals HDMI. It can NOT work with mainstream audio/video devices featuring HDMI inputs.
Outputs 256fs main clock or LRCK/WCLK (3.3V LVDS @ 50 Ohm) . User selectable .
REGENERATIVE POWER SUPPLY
Integrated regenerative power supply is a proprietary electric generator built into the unit to eliminate noise from main power and deliver ultra-low noise and clean AC wave to feed the DDC. It will regenerate the main power and block noise from the power line , this will lead to most neutral and analog sound you can imagine.
A discrete balanced regenerative wave generator produces the new ultra-low noise wave form at 400Hz. The 400Hz frequency was chosen because they have better efficiency compared to traditional 50Hz and at this frequency, 400Hz, it will boost the sound to reproduce real and pleasant analog sound. The balanced gain amps with powerful output stages are driving the regenerative transformers to produce the extreme clean AC power. The extreme regenerated clean AC power is send to separate class A PSUs power supplies for both left and right channel.
