User manual HARMAN KARDON HK6650R

[. . . ] If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product. The power cord of the product should be unplugged from the outlet when left unused for long periods of time. If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. [. . . ] If there are fewer than 30 stations, the tuner will cycle through again, filling up the higher preset slots with the same stations. The scan will stop when all 30 presets have been filled, or after three scans through the FM band. Clear: Press this button to clear a radio station frequency you have started to enter. Control Cover: This cover slides down when you gently press the recessed area down and toward the bottom of the remote, revealing the Numeric Keys and some additional controls.

To make it easier to keep them all straight, the Consumer Electronics Association (CEA®) has established a color-coding standard. Table 1 may be helpful to you as a reference while you set up your system. 1 2 3 Figure 2 ­ Binding-Post Speaker Terminals With Bare Wires Table 1­ Connection Color Guide Audio Connections Left Front (FL/FR) Right Subwoofer The subwoofer is a specialized type of loudspeaker that is usually connected in a different way. The subwoofer is used to play only the low frequencies (bass), which require much more power than the other speaker channels. In order to obtain the best results, most speaker manufacturers offer powered subwoofers, in which the speaker contains its own amplifier on board. Sometimes the subwoofer is connected to the receiver using the front left and right Speaker Outputs, and then the front left and right speakers are connected to terminals on the subwoofer. More often, line-level (nonamplified) connections are made from the receiver's Subwoofer Outputs to corresponding jacks on the subwoofer, as shown in Figure 3. Thus, you have the option of connecting each jack to the line-level input on a separate subwoofer. If you have only one subwoofer with a single line-level input, connect it to the right Subwoofer Output on the HK6650R. Video Connections Composite Types of Connections This section will briefly review different types of cables and connections that you may use to set up your system. Speaker Connections Speaker cables carry an amplified signal from the receiver's speaker terminals to each loudspeaker. Speaker cables contain two wire conductors, or leads, inside plastic insulation. See Figure 5. Composite video cable Figure 5 ­ Composite Video Composite video Antennas The HK6650R uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner. See Figure 6. Figure 6 ­ FM Antenna The AM loop antenna needs to be assembled. See Figure 7. Figure 7 ­ AM Antenna 15 15 SPEAKER PLACEMENT Before you begin to connect cables, it is important to set up your speakers in their correct locations in the room. Optimally, the front left and right speakers are placed the same distance from each other as from the listening position, or about 60 degrees apart, and angled toward the listener. The subwoofer's location is less critical, since low-frequency sounds are omnidirectional. Placing the subwoofer close to a wall or in a corner will reinforce the low frequencies, and may create a "boomy" sound. You may wish to experiment over time by placing the subwoofer where the listener normally sits and then walking around the room until the low frequencies sound best. Place the subwoofer in that spot.

Before beginning, make sure that all components, including the HK6650R, are turned completely off and their power cords are unplugged. Don't plug any of the power cords back in until you have finished making all of your connections. Select a location that leaves several inches of space on all sides of the receiver. [. . . ] In Auto Tuning mode, press and hold the Tuning Buttons (front-panel or remote) to scan in the chosen direction until a station with acceptable signal strength is detected. In Manual Tuning mode, with each press of the Tuning Buttons the HK6650R will tune the next frequency increment (0. 1MHz for FM, or 10kHz for AM) in the selected direction. Scan) Button on the front panel or remote to scan through the previously programmed preset stations. The tuner will pause for five seconds at each frequency before tuning to the next preset. [. . . ]
