RB-1582 MKII
Amplification
Delivering 200 watts per channel, the Rotel RB-1582 MKII supplies the substantial current needed to drive large hi-fi systems with effortless authority. Meticulous circuit design and component selection allow it to reveal music’s finest nuances while retaining the strength demanded by highly dynamic passages. Its performance begins with a substantial toroidal transformer and 60,000 µF of energy storage in special slit-foil capacitors, providing a stable supply to the output stage. These capacitors charge and discharge exceptionally quickly, preserving signal fidelity through orchestral crescendos and repeated bass-drum strikes alike. Beyond the toroidal transformer, the left and right channels follow a monoblock-style layout, with star earthing on a copper grounding plate to minimise noise. Each channel features a discrete output stage comprising ten high-current bipolar transistors, while balanced XLR and unbalanced RCA inputs offer a choice of connections. An accomplished expression of Rotel’s Balanced Design Concept, the RB-1582 MKII is designed to form the heart of an impressive stereo or home cinema system for years to come.
