User manual ROTEL RA-810

[. . . ] Heed all warnings and safety information in these instructions and on the product itself. You must allow 10 cm or 4 inches of unobstructed clearance around the unit. Do not place the unit on a bed, sofa, rug, or similar surface that could block the ventilation slots. If the component is placed in a bookcase or cabinet, there must be ventilation of the cabinet to allow proper cooling. [. . . ] we recommend installing the RA-810 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. The RA-810 is supplied with an RR-AT94 remote control and must be placed where the infrared signal from the remote can reach the front panel Remote Sensor. Keep power cords, digital cables, and audio cables away from each other. This will minimize the chance of the audio signal cables picking up noise or interference from the power cords or digital cables. 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. 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 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 attaching bare wires directly to the binding posts, separate the wire conductors and strip the insulation from the end of each conductor. 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. The left and right channels are clearly labeled and should be connected to the corresponding channels of the source component. use high quality RCA cables for connecting input source components to the RA-810. Because of its relatively high power rating, the RA-810 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 RA-810 and all the other components connected to it. Your RA-810 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 115 volts/60Hz AC or CE: 230 volts/50 Hz AC). [. . . ] The RA-810 has a pair of preamp outputs that can send a variable gain signal to an external power amp or signal processor. The preamp outputs are standard RCA-type output connectors, compatible with the inputs of most power amplifiers. Use high quality cables and be sure to connect the left and right channel outputs of the RA-810 to the correct channels of the amplifier. Once the RA-810 has been turned on with the front panel button, it can be switched between normal operating mode and standby mode with the POWER button on the RR-AT94 remote control. [. . . ]
