Rotel RMB-1555 Multichannel Power Amplifier

Rotel just announced the RMB-1555 five-channel power amplifier which uses the their proprietary Balanced Design Concept for accurate and enjoyable music production. The amp is designed for a powerhouse home theater system or as a distribution amplifier for several independent zones in your home.

Power output is conservatively rated at 120 watts per channel x 5 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 provides 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 designed-in compromises that characterize their integrated circuit cousins. The Class AB amplifier configuration assures the best balance between power output and thermal efficiency for exceptional MTBF (mean time between failure).

Heavy-duty speaker terminals complement the RMB-1555’s 12-volt remote control trigger, single-ended RCA inputs, and detachable IEC-type AC cord. The RM-1555 also self protects from over current, over temperature and DC voltage.
