sources on the Digital to Audio Conversion process
Selectable DAC Mode or Digital Pre-Amplifier Mode, allowing direct connection to Power
Amplifiers and Active speakers in Digital only systems
2.7” High contrast OLED display
“Bit Perfect” Digital Data source analyzer
Intelligent real-time Bit Depth analysis engine Displays the “True” Bit depth of the Digital
input source
Digital Data Decorrelation Engine Decorrelates the fixed “LSB's” data pattern within the
Audio data stream when less then 24Bits. Data decorrelation at the DAC substrate level
reduces both Digital and Analogue Second order effects within the DAC at the silicon Die
level
MS Windows LSB Data restoration for “Bit Perfect” reply corrects Windows' LSB rounding
errors. Allows Bit Perfect “Plug and Play” with Windows Media Player
ASYNC USB Buffer level display to insure correct functionality and diagnostics of the USB
HOST device in ASYNC Audio streaming mode
“Actual” or “Nominal” Sampling Frequency display displays the TRUE input sampling
frequency with 1Hz resolution
Digital level meters in dB with Peak hold
CD / DVD SPDIF subcode embedded Track and Time Display
Advanced De-Jittered Optical and Coax SPDIF Output, with USB to SPDIF output.
Selectable Optical or Coax Clock-Lock interface allowing “Jitter Free” Clock-Locked
connection with compatible CD transports etc.
Full Remote C External Remote / BUS I/O loop
26 Internal regulated supply rails
10 Ultra Low Noise, Low Impedance Discrete Regulators
7 User Selectable Digital Filters Fully Software upgradeable via the USB Port
Master Clock Jitter less then 3pS Short Term - Measured directly at DAC “XOut”
Organic Ultra Low ESR capacitors, High Tolerance Polypropylene film / Foil capacitors,
Ultra Stable Very Low VCR 0.1% MELF SMD resistors, 4 Layer PCB
External upgradeable Power supply interface for a future upgrade path
CROSS Current Regulated Output Stage Solution
