Rotel RMB-1555 Multichannel Surround Power Amplifier

Rotel's power amplifiers have been renowned for decades, garnering critical acclaim. This is due to the venerated Balanced Design Concept, which is rooted in simplicity and exemplary engineering. This ensures accurate, pleasant sound reproduction, proving Rotel's commitment to their "less is more" motto.

Now this same attention to detail – and the same vitality in sonic reproduction – is available for multichannel music aficionados as well as videophiles searching for the best in movie soundtrack recreation.

Case in point: the remarkable RMB-1555 multichannel power amplifier. Whether used in a powerhouse home theatre system, as a distribution amplifier for several independent zones in your home, or as the foundation of a remarkably flexible multichannel music system, the RMB-1555 fulfils the promise of Rotel’s heritage.

Power output is optimistically rated at 120 watts per channel into 8 ohms with every channel driven to peak performance. The RMB-1555 utilises precise control to accurately and authentically reproduce both subtle and intense soundscapes; from the faintest flute tones to the powerful rumblings of a catastrophic event.

Its capability comes from a remarkably stable power supply based on a Rotel-designed and Rotel-built toroidal transformer that provide precise voltages at high current to subsequent circuit stages. In addition, the toroid shape itself reduces stray emissions that might otherwise interfere with signal transfer.

Other internal components are of equally high calibre, sourced from Rotel’s global supply network only after detailed examination and exhaustive listening tests that separate “good enough” from the truly superlative.

The RMB-1555 uses only discrete output transistors with their higher thermal stability and freedom from the designed in compromises that characterise their integrated circuit cousins.

The Class AB amplifier configuration assures the best balance between power output and thermal efficiency. Heavy duty speaker terminals complement the RMB-1555’s 12-volt remote control trigger, single-ended RCA inputs, and detachable IEC-type AC cord. Truly an amplifier for all uses, the RMB-1555 combines superb execution with maximum reliability to demonstrate Rotel’s long devotion to satisfying consumer needs.
