Cyrus PSX-R regulated external power supply


Cyrus PSX-R Features:

  • Provides an extremely smooth and stable DC feed, helping the partnered component to achieve its full potential.
  • 300VA toroidal transformer with an enormous current delivery capability
  • 30,000 microfarad slotted foil reservoir capacitors ensure that very low ESR and wide bandwidth
  • Symmetry: this wide dual bandwidth DC amplifier works as a linear voltage regulator in an identical manner for the positive and negative sides of the PSX-R
  • Current sharing fast double output power transistors ensure quick response in providing the demanded current from the partnering unit
  • Low noise high gain amplifiers in a propriety design provide the remarkable load and line regulation
CYRUS PSX-R separate power supply

What does a PSX-R do for my Cyrus products?

The PSX-R is a separate power supply that may be added to most Cyrus models. It’s connected to the mains and acts like a giant battery. The PSX-R feeds the highly tuned audiophile circuitry in your CD or amp with super smooth ‘regulated’ DC power to allow the advanced circuitry to perform without the ‘noise’ that is present in the public mains supply.We describe a PSX-R as a resolution enhancing upgrade. A system could include a number of PSX-Rs for several components.

In low Power applications such as DACs, Preamplifiers and CD players the PSX-R provides a highly stable external power supply with massive inertia which ensures ideal battery like operation.

In high Power applications the PSX-R establishes a very stiff voltage source behind the power amplifier and successfully inhibits mains related distortions and charging spikes from reaching the signal lines of the amplifier.
