Cyrus X power Stereo power amp



X Power - Power Amplifier - available in Quartz Silver and Brushed black.

This is currently the first power amplifier in the Cyrus range.

Cyrus' best stereo power amplifier!

This amplifier is the perfect partner for the Cyrus X series preamplifiers such as the Pre Xvs and the DAC XP where the system does not demand the driving power of the mighty Mono X. In true Cyrus style the X Power is packed with a long line of features to enable total system flexibility and the possibility of progressive upgrade routes to double the system power up to a full 140W 8Ω when switched to mono with a PSX-R connected.

•Conservatively rated at 70W, the X Power design includes a vastly over-specified power supply bringing considerable dynamic power in excess of the rated RMS figure, essential when driving difficult loads. Technically competent, the X Power ranks highly amongst its peers for technical specifications such as noise, distortion, damping factor and current delivery.

•With the X Power working with its partner the Pre Xvs, there are many different system configurations that can be arranged for the pair. From a single X Power in a high quality pre/power system through 2-amp systems (either bi-amped stereo for quality, or configured as mono for high power) to the ultimate 4-box bi-amp mono system. Further upgrades are possible at any stage by connecting PSX-R power supplies, taking the ultimate X Power system to a full 8 boxes!

•The X Power is also an excellent upgrade for a Cyrus integrated amplifier, such as the Cyrus 8vs, either to upgrade the performance of the internal power amplifier, or to use both the internal power amp and the X Power in a bi-amped configuration. The fixed gain structure of the Cyrus range enables any Cyrus power amplifier, such as the X Power, to be matched for bi-amping to any Cyrus integrated amplifier with a pre-out connection.

•The X Power includes a port for connection of the PSX-R power supply. The PSX-R is a high capacity, fully regulated power supply with even more capacity than the internal power supply of the X Power. The benefits of the super-quiet DC power from the PSX-R will be primarily experienced as an upgrade in the sound of the system, although the power output of the X Power will also be increased, particularly when operating as a mono amplifier.

•The X Power features a sophisticated music-sense circuit with microprocessor control. When the unit is set to low-consumption Standby a high-sensitivity circuit will detect an incoming music signal and switch on the amplifier noiselessly ready for use. A precision timer in the control system will then hold the amplifier on for 4 minutes before resetting to a semi-Standby state. From this state the amplifier can be wakened instantly so that even subtle low-level background music or effects signals will not be lost as the amplifier exits standby. If music is not present for an extended period then the X Power will revert back to its true low-consumption standby state.

•As an alternative means of power control when used in a Cyrus system, the X Power includes connection for the Cyrus MC-Bus system. In this case the intelligence in the control system will detect that the user has chosen to use MC-Bus control and will de-activate the music sensing control system.

•For applications with systems where music-sense is not required and MC-Bus is not connected, the music-sensing system may be disabled, temporarily by holding the standby key down when first switching on the X Power mains power, or permanently by moving a small jumper connector internally on the PCB.

•The computer control system of the X Power also monitors the general status of the amplifier and can react quickly enough to protect it from accidental short-circuits, even when running at full power.

•The quality lightweight die-cast enclosure of the X Power has a myriad of advantages both electrically and mechanically.  The integrated heatsink design enhances the thermal efficiency allowing higher performance to size ratio. Additionally, the non-resonant nature of the alloy minimises microphonic effects, while its non-ferrous composition provides an effective shield from external electro-magnetic disturbances. This also eliminates coupling of the power transformer stray magnetic fields to the sensitive audio circuitry.
