The Rotel RB-1590 Power Amplifier is at the top of its class as a 2 x 350 Watts stereo amplifier with dual toroidal transformers and special slit foil capacitors.
Class AB Amplification
The Rotel RB-1590 is power – refined, detailed, and plenty of it. Rotelโs new Class AB stereo power amplifier has a 350 Watts per channel into 8 ohms rating, both channels driven. That is a lot of power, but larger listening rooms or less sensitive loudspeaker designs require it to bring out the best possible performance and attain realistic audio dynamics.
Massive Toroidal Transformers
The impressive capabilities of the RB-1590 amplifier begin with a solid foundation consisting of twin massive toroidal transformers custom made by Rotel. These transformers are just part of a rock-solid power supply that includes eight special British made BHC capacitors, known for their low loss and quick response times. These components will continue to supply all the voltage and current requirements needed, even under the most difficult load conditions.
Monoblock Design
But power unrefined has never been a Rotel design goal. Every aspect of circuit design has been carefully considered and each component has been rigorously selected after extensive listening sessions. The RB-1590 amplifier circuit topography ensures maximum signal separation and improved stereo imaging with a true Monoblock design.
Features and Functionality
Features include: XLR Balanced and RCA input connections, two pair of 5-way speaker binding posts, 12-volt trigger control, thermal protection circuitry, overcurrent, over-voltage protection circuitry, dual staged power on relay to reduce surge current and extend longevity, and a detachable IEC power cord all in a 5U chassis with included rack ears.
The RB-1590 Power Amplifier is for the most discerning audio enthusiasts and will provide the highest levels of audio performance.
