AS-1 (2021 version) feature:
1, USB transmit the IIS signal to the FPGA processor and receive the
clock signal from the FPGA processor, the USB interface without on
board data clocks, the signal transmit is much exact, the
sound quality get the much improve , close to the last
generative AS-1 combine with DI-20 (But not DI-20HE) level.
2, The ESS9028PRO/9038PRO clock has apply the same
clock of the FPGA.
ESS9028 Pro specs:
Who need the AS-1:
AS-1 is not the lowest
distortion DAC in world, but it had the ultra low distortion and
price is not expensive.
AS-1 is not only declare
with the words has low
distortion, we offer the measure diagram for every single unit (It
is normal that the THD has few DB different, the first 20 units
offer AP SYS-2722 measure diagram, after that will offer AP ATS-2 measure
diagram, ATS-2 measure diagram will has around 6DB worst than
SYS-2722¡A but it is not mean the unit performance worse), verify by the professional
instruments is welcome.
We known that the proper
2nd THD makes the sound become smooth and rich, the proper 3rd THD
makes the sound become transparency and lively, how to adjust the level of
2nd and 3rd THD is the secret technology of the designers, that is why some audio
devices have the higher distortion like phono, and some few very
expensive European made audio devices had better musical to most
people than some others low distortion devices .
We had not applied
technology method to adjust the AS-1 THD effect the sound flavor, we just made it has the
very low distortion , and through selected the different parts apply
to keep the sound listening pleasant . It is not the audio-gd house sound
style.
Who need the AS-1?
I guess that is in
below:
1, Who concern the
specs at first .
2, Who want a
monitor sound to test the cable, room, speakers or somethings
of audio.
¡@ Some specs
of the AS-1 (Measured by AP SYS-2722,unit with 300 hrs burn in):
THD . (the same unit measure in
same minute , the peak level result may has few DB different, so I test the
same unit in different time and post the result in below) :
Distortion to Frequency
(This diagram effect has less effect by the different test time):
Frequency band (This diagram effect has less effect by the
different test time):
Jitter test with 12KHz with the stock clocks. (The clock burn in
time and power supply clean can have few DB effect )
