Cyrus PSU-XR Power Supply

Five Independent Power Supplies

There are five independent power supplies in the PSU-XR. All five power outputs route to a connected XR component through a multi-way umbilical cable:

• A high capacity logic supply to power digital circuitry in a connected XR component.

• Two fixed voltage power supplies that are intended to power sensitive, low voltage analogue circuitry.

• Two variable voltage high capacity power supplies to feed power to low or high consumption analogue circuitry. The variable power supplies also have two unregulated voltage settings that can be applied to boost the power supply in high consumption circuitry such as power amplifiers.

Power Supply Uprades

The sound quality delivered by any audio component, whether an amplifier or a source component such as a CD player, depends heavily upon the quality and capacity of its power supply. The Cyrus PSU-XR power supply upgrade provides a sound upgrade for Cyrus XR components by enhancing both the quality and capacity of their internal power supplies.

Full Isolation For Low Noise

Fifteen separate transformer windings, ground isolated regulation circuitry and separate output power and ground returns in the umbilical cable minimise electrical noise in the multiple power feeds to a connected XR component.
