User manual ROTEL RP-1010

[. . . ] 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. [. . . ] The RP-1010 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 unobstructed. There should be 10 cm (4 inches) of clearance around the chassis, 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 weight. The RP-1010 is supplied with the proper AC power cord. Use only this cord or an exact equivalent. A heavy duty multi-tap power outlet strip may be used, but only if it is rated to handle the current demand of the RP-1010. Be sure the Power Switch on the front panel of the RP-1010 is turned off. Then, plug one end of the cord into the AC power connector 8 on the back panel of the amplifier. When you turn the amplifier back on, the protection circuit will automatically reset and the PROTECTION LED should go out. In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage. To use this feature the adjacent switch 5 must be set in the 12V TRIG position (see previous section). This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The LED indicator above the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position. See Figure 2 The RP-1010 has standard unbalanced RCA-type input connectors, the type used on nearly all audio equipment. There is an RCA input for each of the seven amplifier channels. These RCA inputs accept audio signals from preamplifiers or surround sound processors. [. . . ] The nominal impedance of the loudspeaker(s) connected to each chanel of the RP-1010 in the various operating modes should be no lower than 4 ohms. The RP-1010 has two color coded terminals for each amplifier channel. These speaker terminals accept bare wire, connector lugs, or "banana" type connectors (except in the European Community countries where their use is not permitted). route the wires from the RP-1010 to the speakers.
