DOUK AUDIO D2-PRO Linear Power Supply

The Douk Audio D2 PRO is a 12V linear power supply designed to provide a stable DC voltage to compatible Hi-Fi and digital devices. Its toroidal transformer, LM1085IT regulation and multi-stage filtering allow a maximum power of 35W to be reached, with a ripple noise below 30μV at no load.

Thanks to its two parallel DC outputs, the D2 PRO can simultaneously power two components such as a DAC, a preamplifier, a headphone amplifier or a network device. This architecture combines current capacity, interference reduction and passive dissipation, in order to integrate into an audio setup without adding noisy ventilation.

Douk Audio D2 PRO: Filtering and interference reduction

The power supply integrates several filtering stages intended to reduce disturbances present on the mains and on the DC voltage. The EMI suppression circuit attenuates high-frequency interference before conversion and regulation, while the high-capacity matrix filter acts on high- and low-frequency noise. This architecture allows a ripple noise level below 30 μV at no load to be achieved, with a stated reduction down to 28μV thanks to advanced filtering, in order to provide a cleaner DC power supply to audio and digital circuits.
