Cyrus PSU XR Power Supply Phantom Black

Cyrus PSU XR

The PSU-XR is a smart external power supply designed for exceptional
uniform and stable DC voltages. In this way, the PSU-XR helps the
components connected to it to reach their full potential.

Features and Benefits

• Microprocessor-controlled power supply with 15 taps on the PSU output and the one up to now
  largest toroidal transformer used by Cyrus.
• The internal microprocessor communicated with the host product to determine the exact
  determine the power requirements of the host product. The PSU-XR with its 6
  separate power supplies three different reference voltages to up to five,
  separate circuitry from each host product with superior, clean performance
  supply, which is perfectly generated by the digitally controlled 256 voltage levels
  can become. This makes it incredibly flexible and future-proof.
  
• As with all XR Series products, relay switched 'ultra stable'
  Power supplies are exceptional even under extreme loads
  tension stability.
  
• The power supplies in the PSU-XR have the best possible isolation from extraneous noise. There is none
  common ground inside the PSU-XR, the grounds only meet inside the
  Host products and even here only in places where current flow is minimal.
  This will prevent the circuits from accidentally picking up the musical signal
  affect. The PSU-XR can - and is - deliver 60% more power than the PSX-R2
  50% more efficient thanks to its clever design.
  
• The new PSU XR is much more environmentally friendly. It uses an extreme
  efficient design with multiple taps from the transformer to reduce energy losses
  minimize. The output voltage is fine-tuned using an 8-bit R2R DAC ladder, which means that the output is extremely precise and stable. This design arrangement offers extreme flexibility and future-proofing as it will be able to further improve products that we haven't even developed yet. The new PSU XR thus has a wide range of options for significantly optimizing the performance of the connected host product.

Integrated amplifier: i9-XR with PSU-XR

• The PSU XR and the internal power supply together supply the power amplifiers!
• Further stabilizes the main power supply of the amplifier. That means that
  amplified signal can follow the input signal more closely.
• The preamp section is fully powered by the PSU XR. Here too
  this means a more stable supply for improved precision.
• Allows the internal power supply to power the DAC. This also leads to a
  more stable power supply, since the power pack is less loaded.

Preamp: Pre-XR with PSU-XR

• The PSU-XR takes over the supply of all analogue preamp stages.
• Allows the internal power supply to power the DAC.
• This combination works particularly well here because the internal transformer
  specially developed for the supply of small signal circuits.
  

CD Player: CDt-XR & CDi-XR with PSU-XR

• The PSU-XR supplies the master clock - this is decoupled from interference and
  improves the freedom from jitter.
• The PSU-XR supplies the CD motors and their controls directly.
• From an electrical point of view, this is a very "noisy" circuit, since the motors are constantly activating
  change speed.
• The externalization of this supply from the housing reduces the disturbances
  inside the case, which contributes to the fact that the player is right the first time
  reads precisely.
• In the CDi-XR, the PSU-XR also takes over the power supply for the analogue ones
  Filter stages of the DAC.
• The DAC's digital circuitry is powered by the internal power supply.
