Product Information

Recognized by thirty years of awards and accolades, Cyrus consistently pushes the boundaries of audio technology.

The new Phono Signature is arguably the most advanced phono preamplifier available anywhere in the world today. Designed to exceed the expectations of the most serious vinyl audiophiles, particularly in areas such as outright musical performance, accurate cartridge matching, and flexibility of use.

Phono Signature has been designed to allow up to four turntables to be permanently connected because many vinyl enthusiasts enjoy multiple turntables, arms, or cartridges for different records. Each of the four inputs can be accurately matched to the exact specification of the cartridge and the acoustic preference of the user. Adjustment is provided for MC cartridges in gain, resistance, and capacitance. In addition, a switchable warp filter is provided to maximize amplifier performance.

Four Turntable Connections

Four turntables may be permanently connected, allowing the listening to easily switch between turntables, arms, or cartridges as desired.

Each input may be adjusted between MM or MC, gain, resistance, and capacitance. Settings are conveniently saved to memory for future reference.

Remote Controllable

Remote control of all the main adjustment options from the convenience of the listener's chair.

PSX-R2 Upgradability

Additional performance will be gained by connecting the optional external PSX-R2 power supply. This provides highly regulated DC power for signal amplification.

Level Display

Stereo output level meters working in real-time allow clear and accurate gain adjustment to optimize the headroom available from your system for each MC cartridge.

Advanced Circuit Design

Phono Signature enjoys a high capacity and very low noise DC power supply that enables the preamplifier to provide an extremely wide dynamic range ensuring extended signal levels long before clipping. Attention to circuit layout and component placement ensures a very low noise floor to further expand musical dynamics.

No-compromise Signal Path Components

The passive RIAA filtering uses very high-performance metalized polyester capacitors for ultimate accuracy and performance.
