User manual HARMAN KARDON HD7600

[. . . ] If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. 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. [. . . ] For your subwoofer, the important figure is the highest frequency it is capable of handling. For example, if the subwoofer has a frequency response of 25Hz ­ 150Hz, then 150Hz is the highest frequency it can handle. Some subwoofers allow you to adjust the frequency crossover. Consult the subwoofer's owner's manual for instructions on setting its crossover, and use the approximate number you selected. Measure the distance from each speaker to the listening position. This is used for setting the delay. Step Three ­ Audio Adjustments This menu allows you to adjust bass management settings that control the audio output of the 6-Channel Audio Outputs for speaker size, output level and delay times. The proper adjustment of these settings is key to optimal reproduction of DVD-Audio discs, when the HD7600 is used with a receiver or processor that does not have audio adjustment capabilities for the direct inputs. These settings are only effective when the Bass Management line of the AUDIO SETUP submenu is set to On. IMPORTANT NOTE: In order to avoid audio problems, when the HD7600 is connected to a receiver that does have the capability to adjust bass management parameters for its multichannel inputs, it is preferable to use the receiver for these adjustments. In that case, remember to set the Bass Management setting in the AUDIO SETUP menu to Bypass. If you make the adjustments using the HD7600's settings, it is important that the receiver's settings for the multichannel direct inputs be disabled, or set to "Large" for the speaker sizes and "0" for the level adjustments and delay times, unless these settings are also used for the receiver's other source inputs, in which case they should be left the way you set them when you configured your receiver. Usually the director reduces the loudness, or even the presence, of information in the surround channels so as not to distract the viewer from the main action taking place on screen. If the test tones on your test disc sound as loud in the rear speakers as they do coming from the other speakers, the HD7600 is performing correctly. In many cases the factory default setting of 0dB should accomplish that. However, in some cases the specifics of your listening room may require some adjustments. 28 To adjust the output levels, first insert a disc with test tones or content you are familiar with, and that has a reasonably even level without many dynamic changes. If you are using an SPL meter with a disc containing test tones, adjust the level of each channel so that the meter reads 75dB. If you don't have a meter or a test disc, adjust the levels until all channels sound equally loud. Make sure not to use a surround sound-encoded disc for this process, or the surround channels will be set too high. Use the Navigation Buttons to highlight the level setting for the front left channel. Press the Enter Button to display the available settings, which range from ­6 dB to +6dB, and use the // ¤ Buttons to scroll through them until you are satisfied with the level setting for that channel. Press the Enter button to select the setting, and use the Navigation Buttons to select the next channel. Repeat the procedure to enter the output level offset, if needed, that brings all of the channels to the same output volume. [. . . ] In addition, the HD7600's angle indicator will remain lit in the front-panel display for the duration of multi-angle availability. Progressive Scan: Progressive-scan playback takes the original video signal on the disc and formats it as a high-scan-rate output with twice the scan lines of conventional video images. Progressive-scan outputs must be connected to "digital-ready" or high-definition video displays, regardless of the technology of the specific display (e. g. , conventional direct-view television, front or rear projector, plasma display panel or LCD). In some cases, the displays may have special inputs for use with high-scan-rate inputs, and in others you may need to make adjustments to the display's setup menus to make certain that the inputs used are configured for an "HD" signal.
