Rotel RB-1590


Rotel’s new Class AB stereo power amplifier is rated at 350 Watts per channel into 8 ohms both channels driven.

The impressive capabilities of this 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 of the voltage and current requirements needed, even under the most difficult load conditions.

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.
