Getting Started

Thank you for purchasing the Rotel RB-1080 Stereo Power Amplifier. When used in a high- quality music or home theater system, your Rotel amplifier will provide years of musical enjoyment.

The RB-1080 is a high-power, two-channel power amplifier, providing the highest level of audio performance. Discrete output devices, a massive power supply, premium components, and Rotel’s Balanced Design ensure superb sound quality. High current capability allows the RB-991 to drive the most demanding loud- speakers.

Be aware that the RB-1080 is capable of high power levels, in excess of 200 watts per chan- nel. Make sure that your speakers can handle the power of the RB-1080. If in doubt about your speakers, ask your local Rotel audio retailer for advice.

The RB-1080 is straightforward in its instal- lation and operation. If you have experience with other stereo power amplifiers, you shouldn’t find anything perplexing. Plug in a pair of high-quality RCA cables from your preamp into the amplifier inputs, wire up your speakers, and enjoy. Alternatively, the RB-1080 provides an optional pair of balanced inputs for use with preamps or processors that of- fer these low-noise XLR-connections. If you choose this option, you will need to reset a back panel switch selecting the balanced in- puts. Again, nothing very confusing.

A Few Precautions

Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RB-1080 system configurations as well as gen- eral information that will help you get opti- mum performance from your system. Please contact your authorized Rotel audio retailer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments.

Save the RB-1080 shipping carton and all en- closed packing material for future use. Ship- ping or moving the RB-1080 in anything other than the original packing material may re- sult in severe damage to your amplifier.

Fill out and send in the owner’s registration card packed with the RB-1080. Also be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required.
