4 x 20 bit Fractal-7 matrix, discrete, switch & resistor-based multi-bit power converters
1 x Toslink 16/24 bit: 44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz / 176.4 kHz / 192 kHz
Internal fixed linear power supply
Standard 230V (option: 115V)
Approx. 2 Watts
50 Ohms

2 x RCA output, headphones can be connected through RCA to jack converter cable
RCA35 and a suitable attenuator
Dim = power on, bright = locked
The PowerDAC-BX makes it possible to directly drive many headphones (32 Ohm and up)
without any analogue amplifier or buffer in the signal path. In other words the headphones
are directly driven by a balanced power supply, a number of digital on / off switches and a
resistor array. This eliminates all distortion and degrading that is typically introduced by
conventional headphone amplifiers. With this distortion and degrading completely
removed it is obvious that we end up with a much cleaner signal that lets one listen much
deeper into the recording and offers a more realistic representation of the recorded music.
A suitable passive volume control should be used to set desired output volume to
headphones or directly to an amplifier.
Theoretically 100 MHz (based on switching speed)
< 0.001% (0dB)
