Rotel RB-1582 MkII power amplifier


RB-1582 MKII Stereo Class A/B Power Amplifier

The RB-1582 MkII’s high-end performance begins with an extremely large toroidal transformer combined with a total of 60,000µF storage capacity in special “slit foil” capacitors to provide completely stable power to the output stage. The output stage is a discrete design that consists of 10 high-current bipolar transistors per channel. Input options consist of both balanced XLR and unbalanced RCA connectors.

  • Slit foil capacitors have the ability to charge and discharge extremely quickly, thereby ensuring signal fidelity during orchestral crescendos or repetitive kick-drum impacts, for example.
  • Both left and right channel construction are laid out in a mono block design (after the toroidal transformer) and all grounding is terminated in a star pattern on a copper grounding plate to ensure low signal to noise.
  • At 2 x 200 Watts per channel and utilizing Rotel’s Balanced Design Concept for superior performance, the RB-1582 MkII is a compelling stereo amplifier.
  • Class AB amplifier design
  • High-quality slit foil capacitors made in Britain
  • Balanced XLR inputs
