Harman Kardon AVR 7300 Owners Manual - Page 27

SYSTEM CONFIGURATION When NONE is selected, the system will adjust so that only 5.1-channel modes are available. When this is the case for your system, you may wish to use the surround back amplifier channels to power a second set of speakers whose source is selected by the AVR 7300's multiroom system. See page 39. When SMALL is selected, the system will adjust so that the full complement of 6.1/7.1 modes are available, and low-frequency information below the crossover point will be sent to the subwoofer output. If you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the surround back channels. When LARGE is selected, the system will adjust so that the full complement of 6.1/7.1 surround processing/decoding modes are available, and a full-range signal will be sent to the surround back channels, with no low-frequency information sent to the subwoofer output. When you have completed your selection for the surround back channels, press the ¤ Navigation Button o to move the cursor to SUBWOOFER. Press the ‹/› Navigation Button o to select the option that best describes your system. The choices available for the subwoofer position will depend on the settings for the other speakers, particularly the front left/right positions. If the front left/right speakers are set to SMALL, the subwoofer will automatically be set to SUB, which is the "on" position. If the front left/right speakers are set to LARGE, three options are available: • If no subwoofer is connected to the AVR 7300, press the ‹/› Navigation Button o until NONE appears. With this option, all bass information will be routed to the front left/right "main" speakers. • If a subwoofer is connected to the AVR 7300, you have the option to have the front left/right main speakers reproduce bass frequencies at all times, and have the subwoofer operate only when the AVR 7300 is being used with a digital source that contains a dedicated low-frequency effects, or LFE, soundtrack. This allows you to use both your main and subwoofer speakers to take advantage of the special bass sounds created for some movies. Press ‹/› Navigation Button o until SUB (LFE) appears. • If a subwoofer is connected and you wish to use it for bass reproduction in conjunction with the main front left/right speakers, regardless of the type of program source or Surround mode you are listening to, press the ‹/› Navigation Button o until SUB L/R+LFE appears. When this option is selected, a full-range signal will be sent to the front left/right "main" speakers, and the subwoofer will receive LFE information and the bass frequencies under the selected crossover point. When all initial speaker "size" settings have been made, you now have the option to take advantage of the AVR 7300's Quadruple Crossover system, which allows individual crossover settings to be made for each speaker group. The low-frequency crossover point is the frequency below which the signal will be redirected to the subwoofer and is set by the design of your speakers. Depending on the design and driver complement of your speakers, it is usually the lowest possible frequency the speaker is capable of reproducing. Before making any changes to the settings for the crossover point, we suggest that you find the crossover point for the speakers in each of the four groupings, front left/right, center front, surround and surround back, by looking at the specifications page of each speaker's owner's manual, by getting that information from the manufacturer's Web site, or by contacting your dealer or the manufacturer's customer service department. You will need this figure to accurately configure the next group of settings. Note that when any speaker group other than the front left/right speakers is set to LARGE, the crossover may not be adjusted, as the feed will be full-range, with no sound being derived for the subwoofer from that position. The factory default setting for all speaker positions is 100Hz. If that setting is acceptable for all channels, then no adjustments are needed and you may skip this section. However, should you wish to change one of the settings, please proceed by pressing the ⁄ Navigation Button o so that the cursor moves back up to the MODE line. Press the ‹/› Navigation Button o so that X-OVER appears and the menu data will change to the screen shown in Figure 8. ** SPEAKER SETUP ** → MODE :X-OVER LEFT/RIGHT:100HZ CENTER :100HZ SURROUND :100HZ SURR BACK :100HZ LFE :LEFT/RIGHT BASS MGR :GLOBAL BACK TO AUDIO SETUP Figure 8 To change the setting for any of the four speaker groups, press the ⁄/¤ Navigation Button o until the cursor is next to the speaker group where you wish to make a change and then press the ‹/› Navigation Button o until the desired setting appears. The available choices for low-frequency information to be sent to the subwoofer, rather than to the main speaker channel, are 40Hz, 60Hz, 80Hz, 100Hz, 120Hz and 200Hz. Pick the choice that is identical to the information for the speakers, or if an exact match is not possible, pick the closest choice that is ABOVE the speaker's low-frequency limit to avoid the creation of a low-frequency "hole" where your system will have no bass information. The setting for the crossover point for the LFE channel, which is created to provide specific low-frequency information in many movies with digital soundtracks, may be set to match the crossover for any of the four speaker groups. Since the crossover point commonly used in the creation of the LFE channel is 120Hz, we recommend that you select the speaker group whose crossover point is closest to 120Hz. To do this, press the ⁄/¤ Navigation Button o until the cursor is next to the LFE line, and then press the ‹/› Navigation Button o until the name of the speaker group with the desired crossover frequency appears. Of course, you may also experiment with different settings to find the one that provides the smoothest and most complete bass response in your particular listening environment. When all crossover settings have been made, or in those cases where none are needed, press the ¤ Navigation Button o so that the cursor is next to the BASS MGR line to make the final setting on this menu. This setting allows you to use the same speaker configuration and crossover settings for all inputs, or to have different settings for each input. In most cases, the factory default setting of GLOBAL will be appropriate, as most systems do not need individual speaker settings. However, when full-range front speakers are used for both movies and music, different bass management settings may be used when listening to music through a CD player as opposed to a movie from a DVD player, VCR or cable/satellite set-top. To customize the speaker-size configurations to each input, make certain that the MODE line of the SPEAKER SETUP menu is set to SIZE, and that the cursor is on the BASS MGR line. Press the ‹/› Navigation Button o so that INDEPENDENT appears. When this choice is entered by exiting the menu, the settings just entered will apply to the current input ONLY, and you will need to go back to the IN/OUT menu to select another input, and then return to this menu page to change the settings for the next input. Repeat the procedure for any input where you wish to have a different set of SYSTEM CONFIGURATION 27
