Rotel RB-1590 stereo power amplifier silver

The ROTEL RB-1590 is a Class AB stereo amplifier rated at 350 watts per channel into 8 ohms with both channels driven. That's a lot of power, but large rooms or less sensitive speakers require it to achieve maximum performance and lifelike audio dynamics.

The ROTEL RB-1590's impressive capabilities begin with a solid foundation of Rotel's rugged dual toroidal transformers. These transformers are part of a rugged power supply comprising eight special British-made BHC capacitors, renowned for their low losses and fast response times. These components will continue to supply all the voltage and current needed, even under the most demanding load conditions.

But unrefined power has never been a design goal at Rotel. Every aspect of the circuit design has been carefully considered and every component has been rigorously selected after extensive listening sessions. The circuit topography is a true monoblock design that ensures maximum signal separation and improved stereo imaging.

Features of the ROTEL RB-1590 include: balanced XLR and RCA input connectors, two pairs of 5-way speaker binding posts, 12-volt triggering, thermal protection circuitry, over-current and over-voltage protection circuitry, dual-stage power relaying to reduce current spikes and increase life, and a detachable IEC power cord, all in a 5U chassis with included rack ears.

The ROTEL RB-1590 is designed with the serious enthusiast in mind and is capable of delivering the highest levels of audio performance.
