Thank you for purchasing the Rotel RB-1090 Stereo Power Amplifier. When used in a high- quality music or home theater system, your Rotel amplifier will provide years of musi- cal enjoyment.

There is nothing understated about the RB-1090. It is a massive two-channel power amplifier, capable of providing extremely high power output in the most demanding applications. In fact, the limiting factor in the RB-1090’s output levels will often be the capacity of your home’s electrical supply. Discrete output devices, a massive power supply with dual toroidal transformers, pre- mium components, and Rotel’s Balanced De- sign ensure superb sound quality. High cur- rent capability allows the RB-1090 to drive difficult speaker loads with ease, including 2 ohm speakers.

Be aware that the RB-1090 is capable of high power levels, in excess of 400 watts per chan- nel into 8 ohms and 700 watts into 4 ohms. Make sure that your speakers can handle the power of the RB-1090. If in doubt about your speakers, ask your authorized Rotel dealer for advice.

The RB-1090 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

apair of high-quality RCA cables from your preamp into the amplifier inputs, wire up your speakers, and enjoy.

Alternatively, the RB-1090 provides an op- tional pair of balanced inputs for use with preamps or processors that offer these low- noise XLR-connections. If you choose this op- tion, you will need to reset a back panel switch selecting the balanced inputs. Again, nothing very confusing.
