Rotel RB-1590: Amplifier for the most discerning audio enthusiast

The Rotel RB-1590 is a best-in-class stereo amplifier with 2 x 350 watts of power, dual toroidal transformers and custom slot foil capacitors. Rotel’s new stereo power amplifier is Class A/B and delivers 350 watts into 8 ohms with both channels driven simultaneously. That’s a lot of power, and it’s ideal for larger listening rooms and for less sensitive speaker systems that require a fair amount of power to achieve the best sound quality with realistic dynamics.

The impressive capabilities of the Rotel RB-1590 amplifier are based on a solid foundation consisting of a pair of massive toroidal transformers designed and manufactured by Rotel. These transformers are just part of a rock-solid power supply that uses eight UK-made BHC storage capacitors, known for their low loss and fast response times, to improve the transient response of powerful audio signals and dynamic bass. These components will continue to supply current and voltage as required by the amplifier circuit, even under the most challenging load conditions.

However, raw power was never the design goal for Rotel engineers. Every aspect of the Rotel RB-1590 amplifier circuit has been carefully examined and every component meticulously selected after extensive and rigorous listening tests. A true monoblock design was chosen to implement the circuit topology, ensuring maximum channel separation and enhanced stereo imaging.

The full list of features includes: XLR balanced and RCA input connectors, two pairs of speaker terminals, overcurrent, voltage and temperature protection circuits, two-step relay switching circuitry to avoid surge current and extend life, all in a 5U high package. which comes with “ears” for rack mounting. The Rotel RB-1590 is designed for the most discerning audio enthusiast and delivers the highest level of audio quality possible.
