25、witching 12 volt trigger connections for remote turn on/off by Rotel preamplifiers and surround processors. Full-function wireless remote control Unpacking Remove the unit from its packing. Look for the handheld remote control and other ac- cessories. Install the supplied batteries in the remote con

26、trol. Save the packing and box as it will protect the RT-02 if you move or need to return it for maintenance. Placement Place the RT-02 on a solid, dry, level surface away from direct sunlight, excessive heat, high humidity, or strong vibrations. The RT-02 can generate some heat during normal operat

27、ion. If installed in a cabinet, make sure that there is adequate ventilation. Make sure there is enough room behind the RT-02 for easy hookup. Place the unit close to the other components in your audio/video system and, if possible, place it on its own shelf. This will make initial cable routing, ho

28、okup, and any subsequent system changes easier. It also minimizes potential interference or heat buildup from other components. Dont stack heavy objects on top of the RT-02. Do not expose the unit to moisture; this could damage the circuitry and cause a safety hazard. English Contents Numbers refer

32、 10 Specifi cations .10 6 Rear Panel Connections The RT-02 provides rear panel connections for audio line level output, an FM antenna, an AM antenna, a 12V Trigger, a remote IR sensor, and AC power input. NOTE: Do not plug any system component into an AC source until system hookup is complete and yo

33、u are confi dent that all com- ponent-to-component connections have been properly made. RCA Outputs w Line level RCA audio outputs send a fi xed-level stereo signal from the RT-02 to your preampli- fi er, system controller, or integrated amplifi er. Use a standard RCA audio cable to connect the LEFT

34、 OUTPUT jack to the left channel tuner input on your system controller and the RIGHT OUTPUT jack to the right channel tuner input on your system controller. AM Loop Antenna q The RT-02 includes a loop antenna to receive AM radio signals. Remove this antenna from the box and locate it near the RT-02.

35、 Connect the 300 ohm twin-conductor wire from the loop antenna to the pair of screw terminals labeled AM LOOP, attaching one wire to each terminal. It does not matter which wire attaches to which terminal, but make sure that the connections are solid and that the two wires do not touch. You may need

36、 to rotate or otherwise reorient the antenna to fi nd the best position. NOTE: To use an outdoor antenna, con- nect its 300 ohm twin-conductor wire to the G and AM terminals in place of the loop antenna, only after a professional contractor has installed the antenna system in accor- dance with local

37、 electrical codes. FM Antenna = The RT-02 is supplied with a T-shaped indoor FM antenna. Remove this antenna from the box and connect its attached coax F-type plug to the FM antenna connector on the RT-02. For best reception, unfold the T-shaped antenna. Eyelets at both ends of the T allow tacking t

38、he antenna to a wall, if desired. Experiment with positioning for best reception. NOTE: To use an outdoor antenna, connect its 75 ohm coax lead wire to the FM connec- tor in place of the indoor wire antenna, only after a professional contractor has installed the antenna system in accordance with loc

39、al electrical codes. In the USA, you will need to use the supplied F-type converter to connect the 75 ohm coax cable to the antenna input. AC Input t Your RT-02 is confi gured at the factory for the proper AC line voltage in the country where you purchased it (115 volts AC at 60Hz in the USA and 230

40、 volts AC at 50Hz in Europe). The AC line confi guration is noted on a de- cal on the back of your unit. Make sure that your unit is confi gured properly for your AC line voltage. Plug the supplied cord into the AC INPUT re- ceptacle on the back of the unit. Once all other rear panel connections are

41、 completed, plug the power cord into an AC wall outlet or switched AC outlet on another system component. 12V TRIGGER Connection e The RT-02 can be activated by a 12 volt trigger signal from a Rotel preamplifi er. The trigger input accepts any control signal (AC or DC) ranging from 3 volts to 30 vol

42、ts. When a cable is connected to the input and a trigger signal is present, the tuner is activated. When the trigger signal is interrupted, the tuner goes into standby mode. The front panel indicator light remains lit, but the display goes dark and the unit will not operate. NOTE: When using the 12V

43、 Trigger fea- ture, leave the POWER button in the ON position. EXT REMOTE IN Jack r This 3.5mm mini-jack receives command codes from industry-standard infrared receivers (Xantech, etc.) via hard-wired connections. This feature could prove useful when the unit is installed in a cabinet and the front-

44、panel sensor is blocked. Consult your authorized Rotel dealer for information on these external repeaters and the proper wiring of a jack to fi t the mini-jack receptacle. Basic Operating Controls The following explanations will help you get familiar with the features and controls. When a function i

45、s available on both the front panel and the remote, a number (see front panel illustration) and a letter (see remote control illustration) are shown in the instructions. For example, to change from the AM to FM band, you can either press the front panel button or use the button on the remote. When o

46、nly one identifi er appears, that control is available only on the front panel or the remote, but not both. NOTE: Controls used for tuning the AM/ FM receiver are described in the next sec- tions of this manual. Power Button 1 and Power LED 2 The POWER button is located on the front panel of the RT-

47、02 and is not duplicated on the remote control. Push the button IN to turn the unit on. The LED above the switch and the front panel display will light up. Push the but- ton again (returning it to the OUT position), to turn the unit off. NOTE: If you are using a switched outlet on another component

48、to power the RT-02 or if you are using the 12 volt trigger feature, leave the POWER switch in the ON position. Remote Sensor 3 This front panel sensor receives infrared signals from the remote control. Make sure you do not accidentally block this sensor with cables or accessories. RT-02 AM/FM Stereo Tuner 7 Front Panel Display 4 The large fl uorescent display in the center por- tion of the RT-02 provides status information used in operating the AM/FM receiver (such as station frequency display, band, preset memory, RDS information, etc.).
