The Rotel RB-1552 MkII amplifier operates in class A/B and outputs 120 watts into each of the two channels. Its design is built with high power and reliability, but at the same time, the main focus is on the ability to extract the finest nuances from even the most complex musical compositions. The fanatical attention of Rotel engineers to the smallest details means that the total amount of their efforts becomes more than its components – this is the company's Balanced Design Concept.
