acoustic plan



PhonoMaster is an equipment to amplify electrical signals of phonograph pick-ups. These can be moving magnet (MM) or moving coil (MC) systems. The frequency response is equalized for RIAA.

With minimalistic circuit design best sound quality is achieved without any compromise. Only one transistor is responsible for amplification of the low MC signals. Overallfeedback, differential amplification and push-pull circuits are not used. Adjustment of the MC imput impedance to the pick-up is superfluous due to the use of a current control circuit. Tubes are only installed where they are able to develop their whole range of advantages: for prevention of natural harmonic spectrum, fusion of neutrality and liveliness as well as the exceptional dynamics. One output transistor guarantees low output impedance to drive long cables without losses.

Unregulated switching power supplies avoid any kind of humming and noise. PhonoMaster is equiped with double sided printed circuit boards for tight fixing of ceramic bases and all other components.
