User manual ROTEL RA-960BX

[. . . ] 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. [. . . ] 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 RA-960BX 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 RA-960BX. Be sure the Power Switch on the front panel of the RA-960BX is turned off. Then, plug one end of the cord into the AC power connector 9 on the back panel of the amplifier. Plug the other end into an appropriate AC outlet. Your RA-960BX 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. This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. See Figure 2 The RA-960BX has a standard unbalanced RCAtype input connector, the type used on nearly all audio equipment. This RCA input accept audio signals from preamplifiers or surround sound processors. 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. Some speakers also have Speakon® connectors which make it easy to connect the speakers by simply plugging in wires that are terminated with Speakon® plugs. Even if your speakers do not have Speakon® connectors you can still use speaker wires that have Speakon® plugs on one end. Having two sets of terminals makes it easy to biwire a speaker. The 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 wire(s) from the RA-960BX to the speakers. [. . . ] Standard speaker wire will work, but can result in lower output or diminished bass response, particularly over longer distances. in general , heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of appropriate cables for your system. [. . . ]
