  • Overview

Rotel : RB-1552MKII (BLACK) Classic Stereo Power Amplifier

• 2 x 120 watts @ 8 Ohms
• low magnetic field toroidal transformer
• high-current bipolar output transistors
• balanced XLR or unbalanced RCA connectors

Rotel's RB-1552 has been enhanced and improved in the form of an even more capable class A/B 'MKII' power amplifier, featuring 120 watts per channel. It's been carefully and intricately designed to be durable and robust, while taking care to delicately extract every last element of even the most complex musical recordings. Rotel's highly attentive engineers are able to arrange, align and construct components to form a product that performs with such ability that rival manufacturer's could be given the same resources and struggle to achieve the same result. Rotel claim this is down to their unique 'Balanced Design Concept', and to many listeners - this care and attention to detail is what sets Rotel out from other manufacturers of a similar product. Each stage of the design process is precisely considered to result in the best possible audio performance, from the selection of an over-sized power supply, complete with a highly efficient, low magnetic field toroidal transformer - right down to the multiple, high-current bipolar output transistors. Circuit topology within the RB-1552MKII has been planned, implemented, evaluated and adjusted to offer the best possible results. Featuring left, and right power rectification stages and decoupling, this unit is effectively a mono-block design. The amplifier utilises Rotel 'slit-foil' capacitors;- these provide plenty of reserve energy for extremely dynamic audio passages, and are quick to replenish themselves, thanks to the nature of their unique design. Input options include a balanced XLR or unbalanced RCA connections. This stereo amplifier has been engineered to provide the optimum sound quality, at an affordable price; retaining the same philosophy Rotel have expressed for over 50 years.
