Description

The Rotel RA-1590 stereo power amplifier embodies power at its core. The RB 1590 is equipped with a 2 x 350 Watts stereo amplifier with dual toroidal transformers and special slit foil capacitors. The RB-1590 has been meticulously designed to provide the best-in-class audio performance. Rotel’s new Class AB stereo power amplifier is rated at 350 watts per channel into 8 ohms, both channels driven. However, a large room or a room whose design is less sensitive requires the speaker to be at peak performance and achieve realistic audio dynamics.

Benefits of Rotel RB-1590 Stereo Power Amplifier

Rotel’s new Class AB stereo power amplifier

 

The RB-1590 has been designed for the most discerning audio enthusiast and will provide the highest levels of audio performance. Rotel’s new Class AB stereo power amplifier is rated at 350 Watts per channel into 8 ohms, 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.

Twin massive toroidal transformers custom-made by Rotel

 

The Rotel RB-1590 Stereo Power Amplifier has two massive toroidal transformers. These transformers are part of a solid power supply that includes eight special British-made BHC capacitors, known for their low loss and quick response times. These components will supply all the voltage and current requirements needed, even under the most difficult load conditions.

Circuit topography

Each component has been carefully selected after several listening sessions. The circuit topography has been laid out in a true monoblock design. It ensures maximum signal separation and improved stereo imaging.
