Cyrus Audio
PSU-XR
The PSU-XR is the latest external power supply from Cyrus 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, all of the output voltages from the PSU-XR are all digitally controlled internally, so are extremely stable and virtually noise free. The PSU-XR really is the best performing power supply ever from Cyrus, capable of providing up to 60% more power than the PSX-R2 and due to its revolutionary design, is up to 50% more efficient.
Power Supply Upgrades
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.
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.

Intelligent Configutarion
PSU-XR configuration takes place via the cable from the connected XR component. Each Cyrus design can enable and configure the power supplies in the PSU-XR to meet its circuit requirements exactly.
