Astrotube Power Supply

Every Astrotube microphone deserves a power source as refined as its sound. The PS-AS25 Power Supply is engineered to deliver the precise operating voltages required for unparalleled performance.

Reliable and Noise-Free Performance

The PS-AS25 is built for stability, featuring a high-quality mains transformer and advanced design elements:

  • Medical-Grade IEC Connection: Mains power connects via a robust, medical-grade IEC 320 C14 socket, ensuring safe and reliable power delivery.
  • Regulated DC Filament: The unit features a regulated DC filament supply, which minimizes noise and guarantees the tube operates at its absolute peak, ensuring clarity in every recording.

Seamless Connectivity

We designed the PS-AS25 for integration, not interruption:

  • The microphone connects effortlessly via a Neutrik XLR 5 cable.
  • Crucially, the pure microphone signal is fed directly to an XLR 3 M connector on the microphone body, not on the power supply. This deliberate choice ensures the cleanest possible path to your mic preamp.
