PowerDAC-SX
PAGE 1
DAC type
2 x 28 bit Fractal-15 bridge matrix, discrete, switch & resistor-based multi-bit high power
bridge converters
Digital input
1 x Toslink 16/24 bit: 44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz / 176.4 kHz / 192 kHz
Power Supply
Programmable
i
nternal linear
Standard 230V (option: 115V)
Power Consumption
Approx. 120 Watt peak power, approx. 7W with low signal
Output impedance
2 Ohms for balanced output, regardless of volume setting
Volume control
Volume is controlled by a combination of supply voltage programming (1.5 dB steps) and
bit shifting (6dB steps). This way we can realise
lossless
volume control with no extra
components in the signal path and with 36dB range.
This integrated volume control enables us to directly drive Speakers
Output voltage
179 mV rms ... 11.35 V rms
Output
2 x balanced speaker output
LED display
Volume
0 … 24

PowerDAC-SX and
headphones
The PowerDAC-SX can directly drive balanced headphones or headphones with common
ground using suitable balanced to single-ended transformers
Bandwidth
Theoretically 100 MHz (based on switching speed)
Distortion
< 0.001% (0dB)
