The DSP50x uses a stainless steel chassis with a solid 10 mm aluminium front plate.
A powerful non-switching power supply is used. All sensitive voltages have their own regulators for best jitter performance at the digital outputs. The power switch activates a semiconductor relay which only switches on or off at zero crossings of the mains voltage. This assures a glitch free power switching. The two mains transformers are toroidal types. Mains voltage selection is done automatically by measuring the mains voltage before power is applied to the rest of the electronics.
An internal high precision / low jitter clock generator is responsible for clocking the digital output section. The sampling frequency of that generator can be user selected between the values of 88.2kHz, 96kHz, 176.4kHz, 192kHz. The input signals are converted to the sampling frequency selected.
There are a total of five inputs:
- AES/EBU or S/PDIF via XLR, Toslink and RCA sockets
- UPnP / DLNA via Ethernet
Accepted formats: PCM 44.1kHz up to 384 kHz, DSD 64x / 128x.
Future formats can be accommodated for via software updates.
Roon compatibility is currently in the works.
