Description

The RMB-1555 is a remarkable multichannel amplifier with power output conservatively rated at 120 Watts per channel into 8 ohms (all channels driven!). With all but the most demanding speakers located in extraordinarily large rooms, the RMB-1555 exerts the kind of precise control that presents both nuance and bombast correctly from the faintest flute overtones to the subterranean rumble of an approaching apocalypse.

The RMB-1555 employs a high current, toroidal transformer matched to discrete output transistors with their higher thermal stability and freedom from the designed-in compromises that characterize their integrated circuit cousins. The Class AB amplifier configuration assures the best balance between power output and thermal efficiency.

Engineered with care.

RMB-1555 Internal View

As well-received as Rotel’s CD players have been over the decades, the company’s power amplifiers have been perhaps even more admired and critically acclaimed. That’s due to Rotel’s insistence that “less is more” and proof that the company’s renowned Balanced Design Concept, which emphasizes simplicity and precise execution of proven engineering principles, honors its commitment to accurate and enjoyable musical reproduction.

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 theater 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 fulfills the promise of Rotel’s heritage.

Power output is conservatively rated at 120 watts per channel into 8 ohms and this is with all channels driven to full output. With all but the most demanding speakers located in extraordinarily large rooms, the RMB-1555 exerts the kind of precise control that presents both nuance and bombast correctly from the faintest flute overtones to the subterranean rumble of an approaching apocalypse.

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 caliber. They’re 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 designedin compromises that characterize 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.
