User manual HARMAN KARDON HK40

[. . . ] Use only with the cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. Unplug this apparatus during lightning storms or when unused for long periods of time. Refer all servicing to qualified service personnel. [. . . ] In most cases, the Phase Switch ¢ should be left in the NORMAL position. However, it does no harm to experiment with the Phase Switch ¢, and you may leave it in the position that maximizes bass response. Line-Level Subwoofer (SUB) Input: Connect the subwoofer output of a receiver with digital surround sound decoding, such as Dolby* Digital or DTS® to this input. This , input bypasses the SUB-TS7's internal crossover circuitry, and should only be used with a filtered signal. If your receiver does not have digital decoding, you should use the Line-Level Full-Range Inputs § instead. § Line-Level Full-Range Inputs: Connect the line-level subwoofer output or preamp output(s) of your receiver or amplifier to these inputs. If your receiver does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver's preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the SUB-TS7. If your receiver has only a single subwoofer output, you may connect it to either the left or right line-level input on the SUB-TS7, and no Y-adapter is needed. ¶ Speaker-Level Outputs: If you are using the Speaker-Level Inputs · on the SUB-TS7, you should connect these bindingpost terminals to your front left and right speakers, remembering to maintain polarity by connecting the (+) terminal on the SUBTS7 subwoofer to the (+) terminal on the speaker, and the (­) terminal on the SUBTS7 subwoofer to the (­) terminal on the speaker. If you are not using the SpeakerLevel Inputs ·, then connect your front left and right speakers directly to your receiver or amplifier. See pages 9 through 12 for further information on speaker connections. Most manufacturers of speakers and electronics, including Harman Kardon, use red to denote the (+) terminal and black for the (­) terminal. connected to the correct terminals on your receiver or amplifier. The (+) lead of the speaker wire is indicated with a stripe and has the colored band corresponding to the speaker's position. It is important to connect all speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. To connect the supplied speaker wires to the satellite and center speaker terminals located on the bottom of each speaker, press the red or black tab, insert the bare end of the wire into the hole, and release the tab. Gently tug on the wire to make sure that it is fully inserted. For the best performance, Harman Kardon recommends that the subwoofer be connected using either the Line-Level Subwoofer (SUB) Input or the LineLevel Full-Range Inputs §. However, if the application requires the use of the speaker-level connections for the subwoofer, unscrew the binding-post collar until the pass-through hole in the center post is visible under the collar. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. [. . . ] · Check that the powered subwoofer is plugged in and its Master Power Switch ª is switched on to the "·" position. · Check all wires and connections between receiver/amplifier and speakers. Make sure none of the speaker wires are frayed, cut, punctured, or touching other wires. · Review proper operation of your receiver/amplifier. If there is no sound coming · Check the "Balance" control on your receiver/amplifier. [. . . ]
