User manual ROTEL RA-820

[. . . ] 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 unit. Keep this manual so you can refer to these safety instructions. [. . . ] The Power Indicator light above the Standby button is always illuminated when the RA-820 is connected to a "live" AC outlet. When the Power/Standby is pressed the RA-820 is turned on and the Volume Control LED is illuminated. Pressing the Standby switch again will put the RA-820 in "standby" mode and the Volume Control LED is turned off. Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections. all the inputs of the RA-820 are "line level' inputs. These are appropriate for connecting components such as CD players, Hi Fi or NICAM Stereo video cassette recorders, tuners for audio or video, Laser Disc players or the analog output from a CD ROM drive. If you want to use a phonograph with the RA-820, an external phono equalizer, such as the Rotel RQ-970BX must be used. The Left and Right channels are clearly labeled and should be connected to the corresponding channels of the source component. The Left RCA connectors are white, the Right connectors are red. use high quality RCA cables for connecting input source components to the RA-820. Ask your authorized Rotel dealer for advice about cables. The other outputs from the signal processor are connected to other power amplifiers and speakers. Some Rotel cassette decks can be operated by the RR-927 remote control that come with the RA-820. To use this feature connect a standard 8-pin DIN type cable between the Cassette Remote connector on the back of the RA-820 and the connector on the back of the cassette deck. Control signals from the RR-927 remote control are pick up by the Remote Sensor on the front of the RA985BX and passed to the cassette deck via the cable. These connectors, when used in conjunction with XantechTM brand Video LinkTM IR signal pick ups and repeaters (sold separately by custom system installers), enable the RA-820 to pick up IR remote control signals and distribute them to other components. Contact your authorized Rotel dealer for more information. The Speaker Selector 5 on the front panel controls which set(s) of speakers are operating. If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. If only one set of speakers will be played at any one time, the speakers may have an impedance as low as 4 ohms. [. . . ] Press it again to restore normal sound output. The Volume control LED blinks when the sound is muted. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RA-820, refer to the suggestions for the following conditions: The RA-820 has both thermal and over-current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions.
