Cyrus Classic Power - Power Amplifier

Cyrus Classic Power - Power Amplifier

The Classic POWER is the latest power amplifier within the familiar Classic range. The objective was to create a
significant step up in performance from previous versions by using everything that we learnt when developing the
fantastic XR Series, but retaining the familiar design of the Classic series. The circuit topology has been completely redesigned and the majority of the internal components have been upgraded by the Cyrus R&D team, which has resulted in sound improvements that will help the Classic series retain a loyal fan base for years to come.

Key Features

• Power Output - 2 x 144W into 4 Ω
• Power Output - 2 x 110W into 6 Ω
• Power Output - 2 x 87W into 8 Ω
• THD+N (1kHz, 2/3 power) - <0.002% 6 Ω
• Input sensitivity (110W/6Ω) - 450mV RCA / 900mV XLR
• Input Impedance - 28kΩ
• Frequency response (-3dB) - 48kHz
• S/N ratio (unwtd) - >100dB

The Classic POWER is the latest power amplifier from Cyrus, designed for the new Classic series. The objective was to create a significant step up in performance from previous Classic amplifiers by using everything that we learnt when developing the fantastic XR Series. When combining this knowledge with the overall design of the Classic series, we believe that we have created a stereo power amplifier that offers spectacular quality to price ratio.

The bandwidth is slightly narrower on the Classic POWER, than the Power-XR (the upper -3dB point is 50 kHz), so is best suited to less expensive speakers, providing an ideal solution for people looking for a very advanced yet affordable system.

Due to its high current efficiency, it will drive any speaker with relative ease. Listeners will immediately observe that the amp is much faster, offers an extremely low noise floor and accurately follows the musical signal fed into it. This results in the in a musical experience that is far more faithful and yet remains a true Cyrus experience.

Connectivity

• Unbalanced (RCA) inputs (with daisy-chain out)
  
• Balanced (XLR) inputs
  
• 12V trigger input
  
• MC-BUS connection (control integration with Cyrus system)
  
• PSX-R2 upgrade connection
• Firmware upgrade port

Power Amplifier

The wideband power amplifier of the Classic POWER responds from D.C. to beyond 50kHz ensuring ruler flat frequency response and keeping any undesirable phase shifts out of the audio band.
With a generous, over-specified power supply the Classic POWER power amplifier is very capable of reproducing the scale and drama of the musical performance.

High capacity power supply

The power supply includes a massive 408VA toroidal power transformer delivering power to a high capacity power supply.

PSX-R2 port

The Classic Power includes a port for the PSX-R2 power supply. Power from the PSX-R2 is routed internally to the voltage amplifier stage of the Classic POWER to provide a more stable, low-noise power supply to this key part of the amplifier.

Low power standby consumption

The Classic POWER can be remotely switched to and from a low consumption standby mode via MC-BUS or using the 12V trigger input.
