RME DPS-2 – linear super low noise dual audio power supply with µFilter and sensor technology, in a compact half-rack 19” width housing. Based on the ADI-2 series front panel, it offers two differently filtered DC outputs for exceptional performance, ensuring hum-free operation. Ideal for powering the ADI-2 series and other 12V HiFi components. Features a 60 VA audio toroidal transformer with isolation and magnetic tape shielding, GND lift switch to eliminate ground loop noise, and multicolor status LEDs with AutoDark mode.
The device excels with extremely low noise levels, galvanic isolation, and overload protection, making it perfect for audio environments requiring clean power without interference.
MAIN FEATURES
- Two outputs: Traditional DC with multi-stage passive/active filtering (Linear) and RME's µFilter with sensor technology for ultra-clean DC
- Hum-free operation via 2-stage HF filter, DC filter on AC mains side, and 60 VA toroidal transformer with isolation winding
- GND lift switch to eliminate ground loop noise while maintaining safety, plus ground terminal screw for additional earthing
- Multicolor front LEDs with AutoDark mode, indicating operating modes and errors (power, thermal, overload, undervoltage, short, active output)
- Two 1m DC Sensor connection cables with lockable and non-lockable 2.1 x 5.5 mm DC plugs
- 24-page manual with technical data, measurements, and info on linear and switching power supplies
