Rotel 's Class AB stereo power amplifier delivers a nominal output of 350 watts per channel into 8 ohms with both channels driven. The impressive possibilities of this amplifier begin with a very solid foundation embodied in an impressive toroidal transformer custom made by Rotel . This transformer is just one part of a generous power supply that includes eight special capacitors manufactured by the British company BHC, known for their low losses and extremely fast response times. These components will continue to supply all the voltage and current required even under the most difficult working and loading conditions. But strength without refinement has never been a design goal at Rotel , so every aspect of the RB-1590's circuit design has been carefully considered and every component has been rigorously selected through intensive listening sessions. The circuit topology used is double monophonic in order to ensure maximum separation between channels and improve the stereophonic image. Among the features that deserve to be highlighted are also the following: balanced (XLR connectors) and unbalanced (RCA connectors) input connections, connection terminals to boxes with pentagonal nuts, control by 12 volt trigger signal, protection circuitry against overvoltage and current protection, two-stage start-up relay to reduce current surges and extend longevity, and a removable power cable, all in a standardized 5U chassis with included rack-mount lugs.
