User manual ROTEL RD-835

[. . . ] Do not place objects filled with liquids, such as vases, on the unit. Do not allow foreign objects to get into the enclosure. 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. [. . . ] The RD-835 is a high-power, twelve-channel power amplifier, providing the highest level of audio performance. A massive power supply, premium components, and Rotel's Balanced Design ensure superb sound quality. If installed in a cabinet, make sure that there is adequate ventilation. Your RD-835 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel. The RD-835 must be connected to a polarized 3-pin wall outlet. The RD-835 is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Be sure the power switch on the front panel of the RD-835 is turned off. Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. Plug the other end into an appropriate AC outlet. With the switch in the 12V TRIG position, the amplifier is turned on automatically when a 12 volt trigger signal is present at the 12V TRIG input to the left of the switch. The amplifier goes into standby mode if the +12 volt signal is not present. The front panel POWER SWITCH overrides this function. it must be ON for the +12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. Place the RD-835 on a solid, level surface away from sunlight, heat, moisture, or vibration. Don't stack other components or objects on top of the RD-835. Don't let andy liquid fall into the unit. 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. An input jack for connecting the wires carrying a +12 volt trigger signal from a Rotel preamp or surround sound processor to turn the amplifier on and off. [. . . ] All wire is marked so you can identify the two conductors. there may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with different color conductors (copper and silver). Give yourself enough slack so you can move the components to allow access to the speaker connectors. [. . . ]
