User manual ROTEL RP-830

[. . . ] 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. [. . . ] Be sure the Power Switch on the front panel of the RP-830 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. Your RP-830 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 115 volts/60 Hz , Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel. The RP-830 provides three options for manual or automatic power on/off operation. These modes are selectable using a threeposition slide switch on the back panel: · With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. Use this mode if you are using a switched AC outlet to control power to the amplifier. ⷠWith the switch in the SIGNAL SENSING position, the amplifier turns on automatically when a signal is sensed at the inputs. The amplifier will go into standby mode after five minutes with no signal. The front panel power switch overrides this function. 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. To use this feature the adjacent slide switch must be placed to the left position (see previous section). This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. This pair of RCA connections can be used to pass unprocessed input signals to another audio component, for example to "daisychain" an additional amplifier to drive a second set of speakers. the input signals connected to the "A" inputs are always available at SIGNAL OUTPUT LINK connections. These input signals can also be linked to the "B" and/or "C" inputs by playing the INPUT SELECT switch associated with that pair of inputs in the LINK position. It is useful to think of the RP-830 as three stereo amplifiers in a single chassis. Each of the three pair of amplifier channels can be operated in Stereo or Bridged Mono mode. Bridged Mono mode: Bridged Mono mode more than doubles the power into a single speaker. [. . . ] The size and quality of the wire can have an audible effect on the performance of the system. 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. [. . . ]
