The Cyrus 40 PSU External Power Supply is consistent with any high quality audio system. It is a perfect addition to the already high performance Cyrus product line. The power supply units are continuous, regulated, and noiseless.
Cyrus 40 PSU External Power Supply
Allowing your equipment to operate much higher than it would in noisy and fluctuating power. The Cyrus 40 improves the mains supply and enhances clarity.
Audio Stabilization
As a high end audio application, even slight power/voltage fluctuations can severely distort audio quality. The unit’s well-thought-out circuitry ensures that both electromotive force dropouts (e.g., power line noise) and voltage spikes (e.g., abnormal power supply operation) are virtually non-existent. Thus, the resultant clear power allows crystal-clear sound reproduction through the audio system.
Five Self-Contained Power Supplies
The Cyrus 40 PSU External Power Supply has five self-contained power supplies. All five power outputs are directed to a 40-series component connected using a multi-way umbilical cable. A high-capacity logic supply to power digital circuitry in a connected 40-series component. Two fixed voltage power supplies are intended to be power sensitive.
Low-voltage analogue circuitry and two variable-voltage high-capacity power supplies feed power to low- or high-consuming 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.
MQA decoding
At its core, the 40 ST incorporates a groundbreaking end-to-end (studio speaker) technology called Master Quality Authenticated (MQA) that records and replicates audio of the highest fidelity directly from the artists’ recording sessions to any room in your home.
The 40 ST features an advanced decoder and audio renderer dedicated to the MQA system. Thus enabling you to experience the artist’s sound exactly as it was recorded and approved in the studio.
Airplay2
With Airplay2, you are able to link several players at home to form a network through AirPlay that will enable them to communicate with each other. While you are walking from one room to another. Your music will remain perfectly synchronized or you may want to play something different in each room. In either case, you can control everything from your iOS device.
Well Regulated Power Supply
The array of audio equipment connected to the Cyrus 40 PSU, just being there, is also a shield against power variations, which may cause it to deteriorate. A constant and well-regulated power supply helps prevent stress on internal circuits and early failure on electronic and mechanical audio equipment devices, mainly amplifiers.
The increased efficiency of equipment combined with the advancement in performance enables it to face no or little downtime. Hence, it protects users’ investment in high-quality audio equipment by reducing the need for frequent replacements and repairs.
Features and Benefits
- Ultra-Stable Power Output: The power is sent to the audio devices steadily and free of interference.
- Advanced Filtering Mechanism: The filter technology to this end is aided by a unique design with a comprehensive filtration system. Eliminating all types of power-line noise leads to a clean power delivery.
- Enhanced Audio Clarity: Constantly providing the required power source. It results in precise sound dissemination and definite audio playback.
- Design Consistency: It matches the look of other Cyrus products. Which enables you to create uniform and undisturbed audio systems.
- The lifespan of Components: The effect of products is longer due to less wear and tear use through stable power output.
- Space-Efficient Design: The compact form factor only requires minimal space. Making it the perfect pick for audio setups.
Summary of the Cyrus 40 PSU External Power Supply
The 40 Series manifests a novel style for Cyrus. The 40 PSU continues the ‘half size’ chassis which has been a Cyrus design hallmark since the 80s but at the same time. It is brought up-to-date with a very sleek and modern look. It is as if the brushed and anodised aluminium finish is what gives it that premium appearance and touch.
finish is in perfect harmony with other Cyrus 40 series components. Ssince they are half-sized, they can fit side by side on a single hi-fi shelf
Outstanding Sound Reproduction
With its robust and aesthetic design, the Cyrus 40 PSU External Power Supply is essentially two birds with one stone in the audio setting. On the one hand, it upgrades the device based on the look criteria. Besides concentrating on sound, it also deals with problems related to the safety and usability of the entire system.
Connectivity
The 40 ST comes with a couple of digital inputs – one optical and one coaxial. Which allow for the hookup of external devices like a CD player or TV in order to enjoy the sound quality benefits that come from using Cyrus-engineered DAC circuitry.
