DESIGN HIGHLIGHT
2.1
All New USB Audio Solution
The Ares II is equipped with the proprietary USB Audio Solution via STM32F446 Advanced
AMR Based MCU, with DENAFRIPS redesigned and optimized circuitry, allow the Ares II to
be used as high-end DAC with computers / streamers. It supports 24bit/1536kHz PCM data
stream, and native decoding of DSD up to DSD1024. It comes with licensed Thesycon USB
Driver for Windows Platform.
NOTE:
The USB Module is designed to trigger on only when USB Input is selected. This is
intended design to reduce inputs cross interference for best sound reproduction.
2.2
Proprietary SPDIF DIGITAL AUDIO RECEIVER
The SPDIF Coaxial, TOSLink input support up to 24bit/192kHz digital audio format. The Ares
II abandon the use of Digital Audio Receiver chip. The digital data is decoded by the on-
board FPGA (Field Programmable Gate Array), shorten the signal path and eliminated the
undesired coloration.
2.3
ADAPTIVE FIFO MEMORY CACHE ARCHITECTURE
Adaptive FIFO technology is used to transfer the audio data input to the high-speed RAM
buffer, and, by using the high stability active crystal clock signals generated from within,
extract the audio data from the high-speed to the R2R DAC for DA conversion.
2.4
NOS/OS
Fancy of NOS/OS selection to change the sound signature of the DAC? The Ares II allow the
user to change the sampling mode on the fly. NOS, as the name suggested, does not do
Over Sampling of the digital input stream. The sampling rate of the digital input signal
remain untouched, and it is converted to analogue output signal right away.
2.5
PROPRIETARY R-2R AND DSD DECODING ARCHITECTURE
The Ares II is equipped with 20Bit R-2R DAC to decode PCM data stream and 32 steps FIR
analogue filters hardware decoder to decode DSD data stream. These designs guaranteed
the PCM format can be perfectly decoded, at the same time, the DSD format can be
perfectly decoded as well. It is rare in the currently market that a R-2R DAC can hardware
decode both the PCM and DSD formats.
