Overview Specifications Brochure

The RS250 Power Amplifier offers high performance, reliability and excellent value. More than fifteen years of accumulated experience is incorporated in each amplifier. The RS250 continues to satisfy the requirements of broadcasters, recording studios, theaters, sound reinforcement and other professional users in addition to Hi-fi enthusiasts and music lovers in every part of the country.

The performance of the RS250 is ensured by a high speed direct coupled output stage with low distortion achieved through pure complementary topology and carefully selected devices. The relative simplicity and elegance of the design makes the circuitry inherently more reliable.

In addition, rigorous control at every stage of manufacture from the selection of components through to final testing ensures consistent high performance.

Each power amplifier channel is powered from a separate high current toroidal transformer with over 13000 microfarad reservoir capacitors. The power supply capacity is designed for deal with the most awkward dynamic loads usually associated with real life loudspeakers and this contributes to the amplifiers excellent transient handling capability.
