Description

Rotel’s largest stereo amplifier at 200 watts per channel provides the massive current to drive the very largest hi-fi systems effortlessly. And like its smaller brother, the RB-1582 MKII has been designed to excel at resolving the subtle details in music as well as supplying the brawn required for extremely dynamic passages. It is able to achieve this difficult dual requirement because of the meticulous attention paid to circuit design and parts selection.

Features:

  • 2 x 200 Watts of robust power
  • Class AB amplifier design
  • High quality slit foil capacitors made in Britain
  • Balanced XLR inputs
  • Rack ears included

The RB-1582 MKII ‘s high-end performance begins with an extremely large toroidal transformer combined with a total of 60,000uF storage capacity in special “slit foil” capacitors to provide completely stable power to the output stage. 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. 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.
