Product Description: 

The Rotel RB-1582 MkII is a powerful stereo amplifier delivering 200 watts per channel, designed to effortlessly drive even the largest high-fidelity systems. Like its smaller counterpart, it balances the ability to reveal subtle musical details with the strength needed for highly dynamic passages. 

This dual capability is achieved through meticulous circuit design and careful component selection. Its performance is anchored by a large toroidal transformer and a total of 60,000µF of special slit-foil capacitors, which provide stable power to the output stage. These capacitors charge and discharge rapidly, maintaining signal integrity during intense moments such as orchestral crescendos or repetitive drum beats. 

The amplifier employs a mono block layout for each channel beyond the transformer, with all grounds connected in a star configuration on a copper grounding plate to minimize noise. The discrete output stage features ten high-current bipolar transistors per channel. Input options include balanced XLR and unbalanced RCA connectors. The RB-1582 MkII exemplifies Rotel’s Balanced Design Concept and serves as a robust foundation for impressive stereo or home theater systems for years to come.
