The RB-1552 MKII is a stereo power amplifier that delivers 120 continuous watts per channel in Class AB into 8 ohms. The obsessive attention to detail that characterizes Rotel engineering means that the whole always exceeds the sum of the parts, an idea called the Balanced Design Concept.
Thus, every aspect of the RB-1552MKII design (from the selection of an oversized power supply equipped with a highly efficient, low magnetic loss toroidal transformer, to the use of multiple bipolar transistors with high current delivery capacity) is carefully considered from a holistic point of view in order to maximize sonic performance.
The RB-1552 MKII includes independent rectification and decoupling stages for the left and right channels, essentially being a dual monophonic design. Another demonstration of the level of demand in the design specifications is found in the selection of thin film capacitors of the highest quality that provide a generous energy reserve to reproduce without limitations the most extreme dynamic passages and at the same time are capable of being recharged quickly thanks to to the unique nature of its design.
The result is a stereo power amplifier designed to provide top-level sound performance while, in keeping with Rotel 's tradition for more than 60 years, being exceptionally affordable.
