High power performance

Rotel’s new Class A/B power amp is a real powerhouse, delivering 350 watts into 8 ohms (both channels in use). Ideally suited for larger listening rooms and speakers that require more power to achieve the best possible audio performance.

The RB-1590

In the best Rotel tradition, the RB-1590 is equipped with a single, incredibly generously sized toroidal transformer, manufactured by Rotel itself, with separate windings. However, this transformer is only one part of the ultra-stable power supply. In addition, 8 custom-made BHC slit-foil capacitors (Made in England) are integrated, which are known for their low-loss and fast response time. These components provide a constant voltage under high current demand and the most difficult load conditions.

Every detail of the circuit design has been carefully considered and every component selected after intensive listening sessions. With the exception of the toroidal transformer, the power amplifier has a dual-mono design. The circuit layout ensures maximum signal separation and improved stereo sound image.
