It’s no secret the typical long runs of speaker cable in custom installations present real challenges to amplifiers. The best way to maximize the sound quality of custom speakers is to give them high quality power. Identical in terms of features to their 50 watt per channel cousins but with a full 8 x 100 watts per channel, all channels driven at 8 ohms, the RKB-8100 and RKB-D8100 are Rotel’s most powerful custom installation amplifiers. Yet, they maintain the compact, dual-fan cooled 2U chassis that makes them space efficient in the equipment rack. Either is the perfect solution for higher performance multizone audio systems. Sound quality and reliability have been engineered throughout to make them truly set and forget designs. Dual SMPS power supplies partnered with a high efficiency, low heat, Class D operation and no compromise audio engineering set a new standard for the custom installation amplifier category. Choose either the analog-only input RKB-8100 or the digital + analog input RKB-D8100 as suits the system configuration. In either case, be prepared for an extraordinary audio experience.
