Mechanics
The DAC204 is housed in a silver anodized aluminum frame.
Power Supply
Supplied with medical grade power supply. Optional power supply from our PSU101 discrete reference power supply.
Synchronization
The USB sampling frequency is generated with an internal master clock generator inside DAC204. This makes sure the transfer between computer and D/A Converter with low jitter. Digital Input A USB type B connector is used a connection to the computer. Toslink and SPDIF inputs are also supported. Extremely efficient Jitter attenuation.
Jitter suppression
Several signal reclocking schemes are combined for a high jitter attenuation.
Analog Output Level
Two switches allow to se 4 different output levels at 10dB steps.
Software features
The DAC204 USB interface can do DSD to PCM conversion at selectable sampling frequencies and word-length (88.2 or 176.4 kHz and 16 or 24 Bit). The DSD input is in the DoP format with a sampling frequency of DSD64 (2.8224 MHz) and DSD128 (5.6MHz).
Main Feature
The DAC204 is Oversampling sigma delta D/A converters are used. Four D/A Converters per audio channel are operated in parallel for enhanced signal to noise performance.
Linearity
At 0dBFS to -120dBFS input level: less than ffl0.4dB deviation from ideal
Total Harmonic Distortion plus Noise (THD+N)
-116dBr (0.00016%)@-3dBFS
-125dBr (0.000056%)@-40dBFS
-125dBr(0.000056%)@-70dBFS
Crosstalk
Better than 120dB, 20Hz-20kHz
