If in doubt about your speakers, ask your local Rotel audio dealer for advice. the RB-1510 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. Be sure to keep the power cords and audio signal cables in your installation away from each other. This will minimize the chance of the regular audio signal cables picking up noise or interference from the power cords. Using only high quality, shielded cables will also help to prevent noise or interference from degrading the sound quality of your system. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system AC Power Input Because of its high power rating, the RB-1510 can draw considerable current. Therefore, it should be plugged directly into a 2-pin polarized wall outlet. A heavy duty multi-tap power outlet strip may be used if it (and the wall outlet) is rated to handle the current demanded by the RB-1510 and all the other components connected to it. Be sure the Power Switch 1 on the front panel of the RB-1510 is turned off (in the out position). Then, connect the supplied power cord to the Power Connector - on the back panel of the amplifier and to the AC power outlet.
