Getting Started

Thank you for purchasing the Rotel RB-1050 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-1050 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-1050 to drive the most demanding loud- speakers.

Be aware that the RB-1050 is capable of high power levels, in excess of 70 watts per channel. Make sure that your speakers can handle the power of the RB-1050. If in doubt about your speakers, ask your local Rotel audio dealer for advice.

The RB-1050 is straightforward in its installation 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.

A Few Precautions

Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RB-1050 system configurations as well as general information that will help you get optimum performance from your system. Please contact your authorized Rotel dealer for answers to any questions you might have. In ad- dition, all of us at Rotel welcome your questions and comments.

Save the RB-1050 shipping carton and all enclosed packing material for future use. Shipping or moving the RB-1050 in anything other than the original packing material may result in severe damage to your amplifier.

Fill out and send in the owner’s registration card packed with the RB-1050. 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.

Placement

The RB-1050 generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be open. There should be 10 cm (4 inches) of clearance around the chas- sis, and reasonable airflow through the installation location, to prevent the amplifier from overheating.

Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk. Again, use common sense.
