Rotel RB-1552 MKII. High-Performance Stereo Power Amplifier

The RB-1552 MKII is a Class AB stereo power amplifier engineered to deliver the perfect balance of musicality, power, and precision. With a continuous output of 120 watts per channel into 8 ohms, it reflects Rotel’s commitment to the Balanced Design Concept—a philosophy where every component and engineering choice contributes to the amplifier’s overall sonic performance.

Dual Mono Design and High-Capacity Power Supply

Internally, the RB-1552 MKII features a dual monoblock topology, meaning each channel operates with its own rectification and decoupling stages. This minimizes crosstalk, enhances stereo separation, and ensures uncompromised channel independence.

At the core of the amplifier is a massive, low-loss toroidal transformer, custom-built for Rotel. It delivers stable, clean power, even during intense dynamic passages, and forms the foundation of the amp’s high-current capability.

Audiophile Components and Uncompromising Build Quality

The RB-1552 MKII utilizes high-grade slit-foil capacitors, chosen for their generous energy storage and rapid recharge characteristics—vital for maintaining musical integrity during complex, dynamic content.

Its high-current bipolar output transistors ensure controlled, effortless power delivery, making it capable of driving demanding loudspeakers with authority, detail, and finesse.

Flexible Connectivity and System Integration

To ensure broad compatibility, the RB-1552 MKII is equipped with both balanced (XLR) and unbalanced (RCA) inputs. A 12V trigger input allows for remote power-on integration with preamps, AV processors, or home automation systems—perfect for custom installations or multiroom setups.
