Rotel RB-06 Power Amplifier for Cinema or HiFi, Fully Working, Great Condition. The RB-06 is a full featured, high performance component. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The RB-06 has a highly regulated power supply incorporating a Rotel custom-designed toroidal power transformer. This low impedance power supply has ample power reserves, which enables the RB-06 to easily reproduce the most demanding audio signals. This type of design is more expensive to manufacture, but it is better for the music. The printed circuit boards (PCB) are designed with Symmetrical Circuit Traces. This insures that the precise timing of the music is maintained and faithfully recreated. The RB-06 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been examined to ensure the most faithful music reproduction. The main functions of the RB-06 are easy to install and use. If you have experience with other stereo systems, you shouldn’t find anything perplexing. Simply plug in the associated components and enjoy.
