Reference R-107S

    Compact high performance monaural amplifier approaches ultimate audio quality.

    Created with unlimited channel selection and expandability, the monaural power amplifier is nothing less than the ultimate form of a HiFi amplifier. For a long time in the car audio world, large units that emphasize output relying on subwoofer activation have predominated among monaural power amplifiers, while products for HiFi reproduction suited to driving a main speaker in an assembly of multiple units have barely existed. The R-107S is a compact, high performance power amplifier that moves from “simple, passive, and two-way” to “digital and multi-unit” by taking a reasonable approach to achieving a carefully considered system noted for “one amp per channel” and “one amp per speaker.” Amplifying circuits derived from the Bewith tradition of the Air Circuit concept have achieved a simple design, giving first priority to sound quality, that eliminates the use of heat fins through a low heat generation, low power consumption design in a full-discrete, full-analog layout. Component parts, including a world’s first custom-made power transformer assembled from a low magnetic core and high purity, oxygen-free copper coils, were scrupulously selected. The amp compresses Bewith’s true nature into a compact single unit that approaches ultimate audio quality.
