PSU-XR

The PSU-XR is our latest external power supply and introduces a brand-new approach to providing clean and stable power for your compatible Cyrus XR host product. Incorporating its own on-board micro-processor, the PSU-XR communicates directly with the host product to consistently provide the best configuration of power from a full range of voltage output levels.

Providing multiple supplies, the PSU-XR outputs all voltages digitally, ensuring extremely stable, virtually noise-free operation. The PSU-XR is our best-performing power supply, delivering up to 60% more power than the PSX-R2 and, thanks to its revolutionary design, up to 50% greater efficiency.

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 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.

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.
