The Ruby P-1 is a two-channel phono preamplifier module with very accurate RIAA equalization and many features. The circuit is designed to accept both moving coil (MC) and moving magnet (MM) transducers/cartridges directly without the need for a step-up transformer. Gain and input loading are easy to select via high resolution DIP switches.
It is ideally suited for the most demanding of applications with accurate RIAA equalization to within 0.05db Automated precision assembly of the analog module using surface mounted components with tolerances to 0.1% accuracy reduces the size to the minimum possible allowing for very low noise, extremely low distortion and superior sonic performance.
The power supply is enclosed in its own aluminium chassis and contains separate and completely independent dual power supplies for each channel.
