User manual ROTEL RP-830

[. . . ] Immediately stop using the component and have it inspected and/or serviced by a qualified service agency if: · The unit has been dropped or damaged in any way Place the unit on a fixed, level surface strong enough to support its weight. Three pair of amplifier channels, any of which can be bridged for mono operation (back panel switchable). ⷠFront panel LEDs indicate Bridged Mono mode for each pair of amplifier channels. A family whose passionate interest in music led them to manufacture high fidelity components of uncompromising quality founded Rotel over 40 years ago. [. . . ] Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. 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 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. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a signal is present. Position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3. The amplifier will go into standby mode after 5 minutes with no signal if the +12 volt signal is not present. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. 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 two modes are selected by three rear panel switches, one for each pair of channels. stereo or Bridged Mono configuration is independent for each pair of channels. You can configure some pairs of channels in Stereo mode and others in Bridged Mono mode. The RP-830 provides standard conventional input connections -- unbalanced RCA type connections as found on nearly all audio equipment. There is also a pair of SIGNAL OUTPUT LINK connections for passing the input signal connected to the "A" pair of channels on to another audio component. Additionally, the input signal to the "A" pair of channels can be automatically linked to the inputs for the "B" and/or "C" channels, so that a separate input signal cable is not required for those channels, for example in large systems where the RP-830 is being used to drive multiple pairs of speakers in stereo mode. The RP-830 has three groups of speaker connectors, one for each pair of amplifier channels. These can be used to connect two loudspeakers in Stereo mode, or to connect one loudspeaker in Bridged Mono mode. [. . . ] These allow you to adjust the gain of the amplifiers to match other components in an elaborate system. Use a small flat blade screwdriver to turn the control clockwise to increase gain. The polarity ­ the positive/negative orientation of the connections ­ for every speaker and amplifier connection must be consistent so all the speakers will be in phase. if the polarity of one connection is mistakenly reversed , bass output will be very weak and stereo imaging degraded.
