ROTEL RB-1552 MK II Stereo Power Amplifier

Rotel RB-1552 MKII stereo power amplifier has been engineered to provide high-resolution audio performance with power up to 120 Watts per channel, yet it is very affordable, as has been the tradition with Rotel electronics for over 50 years.

Rotel engineering’s fanatical attention to detail means the sum is greater than the parts; this is what we call our Balanced Design Concept. Each aspect of the design is carefully considered holistically to result in maximum audio performance, from the selection of an over-sized power supply featuring a highly efficient, low magnetic field toroidal transformer to multiple, high-current bipolar output transistors. The circuit topology is planned, implemented, evaluated, and adjusted to achieve optimum results. The RB-1552 MKII 120 watt Class A/B amplifier features independent left and right power rectification stages and decoupling, and is essentially a mono block design. Further evidence of design over-spec is in the selection of premium “slit-foil” capacitors, which provide plenty of reserve energy for extremely dynamic audio passages and are able to quickly replenish themselves due to the nature of their unique design. Input options are balanced XLR or unbalanced RCA connectors.
