User manual ROTEL RA-810

[. . . ] If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. Read all the instructions before connecting or operating the component. Keep this manual so you can refer to these safety instructions. [. . . ] Using high quality, shielded cables will also help to prevent noise or interference. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system. It must be unobstructed or the remote control will not work properly. The operation of the remote sensor can also be affected if it is exposed to bright sunlight or certain types of lighting (such as halogen lights) that emit infrared light. In addition remote control functions may not work reliably if the batteries in the RR-AT94 are weak. NOTE: To use the remote, aim it at the remote sensor on the front panel of the RA-810. If only one set of speakers will be used at any given time, the speakers may have an impedance as low as 4 ohms. If there are times when both the A and B speakers will be used, all the speakers should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RA-810. See your authorized Rotel dealer if you have any questions. Turn off all the components in the system before connecting the speakers. the RA-810 has color-coded speaker connectors on the back panel. These connectors accept bare wire, or connector lugs. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using dual banana plugs, connect them to the wires and then plug into the backs of the binding posts. The thumbscrews of the binding posts should be screwed in all the way (clockwise). If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip the insulation from the end of each conductor. Be careful not to cut into the wire strands. NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connectors. The RA-810 has three pair of conventional RCA input connectors for line level components such as CD players, video cassette recorders, tuners, Laser Disc players, or DVD players. [. . . ] If the turntable has a "ground" wire connect it to the screw terminal to the left of the Phono inputs. Several Rotel amplifiers can be turned on and off using a 12 volt signal, provided by the 12V TRIGGER connection. When the RA-810 is activated, a 12 volt DC signal appears at this connector and will turn on an amplifier. When the RA-810 is turned off, the trigger signal is interrupted and the external amplifier will be turned off. [. . . ]
