Harman-Kardon AVR 445 owner manual Speaker Size Menu

SYSTEM CONFIGURATION

Speaker Size Menu

Although most listeners will prefer to take advantage of the accuracy and speed of EzSet/EQ to make all of the necessary speaker adjustments, advanced users may wish to experiment with how different combina- tions of settings sound in their home theater environ- ment or to use settings other than those calculated by EzSet/EQ, to accommodate personal listening preferences.

The menu system used in your AVR 445 differs somewhat from conventional speaker setup menus in that it consolidates the speaker “size” and crossover into one convenient menu. Even if you are familiar with making these adjustments, it is strongly recommended that you read the following section of this manual.

On the SPEAKER SIZE menu (Figure 18) you have the option to change the type of speaker config- ured for each of the four position groups, to change the crossover setting for any one of those speakers, to adjust the setting point for the low-pass filter that determines which frequencies are sent to the sub- woofer for low-frequency effects (LFE) signals, to change the subwoofer bass redirection mode when the Front Left/Right speakers are set to Large and to change the setting for the subwoofer size. If, as rec- ommended, you have first run the EzSet/EQ system, as shown on pages 26–28, the settings established by EzSet/EQ will be displayed as a starting point for any manual adjustments. You may reestablish those settings at any time during an adjustment on this menu by pressing the ⁄/¤ Navigation Button n© until the cursor is on the EZSET SETTINGS line of the menu and then pressing the ‹/› Navigation Button n© so that ON is high- lighted in reverse video. Note, however, that once this is done, any manual adjustments made will be lost and must be reentered.

Speaker Size

At each of the four speaker group positions, you have the ability to select the speaker “size” and, when a “Small” speaker is selected, the frequency below which low-frequency information is sent to the sub- woofer, as opposed to the speakers for the channel being adjusted. For that reason, before making the adjustments on the FRONT L/R, CENTER, SIDE SURR and BACK SURR menu lines, it is important to know the frequency range for the speaker. This information is typically found in the “Specifications” section of the speaker’s owner’s man- ual. If you cannot find the specification for the lowest frequency the speaker can handle, start with the set- tings entered by running EzSet/EQ and then try one setting above or below the existing entry. We do not recommend changing the crossover point more than that due to the possible impact that will have on the speaker’s performance. If you do not have access

to the owner’s manual for a particular speaker, you should be able to obtain the needed information from the Web site or customer service department of the speaker’s manufacturer.

To manually adjust the speaker settings, go to the SPEAKER SIZE menu by pressing the OSD Button U∫ on the remote and when the MASTER MENU (Figure 1) appears, press the ⁄/¤ Navigation Button n© until the cursor is on the EZSET/EQ line and press the Set Button pœ. Navigate to the EZSET/EQ MANUAL SETUP line and press the Set Button pœ. When the EZSET/EQ MANUAL SETUP menu (Figure 17) appears, press the ⁄/¤ Navigation Button n© again until the cursor is on the SPEAKER SIZE line and press the Set Button pœ.

On the SPEAKER SIZE menu (Figure 18) you will see a display of either the settings that were established when EzSet/EQ was run, or the factory default settings if you have not yet run the automated system.

To change the setting for any of the four speaker posi- tions, press the ⁄/¤ Navigation Button n© until the cursor points to the line where you wish to make the change. Press the ‹/› Navigation Button n© to change the setting, but note that when you do this for the first time in the menu, a warning message (Figure 19) will appear in the on-screen dis- play reminding you to rerun EzSet/EQ after you are finished with any speaker configuration changes. This is necessary to make any level output adjustments needed after the setting changes so that the new configuration will be properly integrated.

The warning message will remain for a few seconds and then the SPEAKER SIZE menu will return to the screen. At this point you may change the set- tings to the “size” or crossover for any of the four speaker positions using the Navigation Buttons n© as shown above. The information below details the settings available for each of the speaker configurations.

At each of the four speaker position lines, you have the option to set the speaker size and crossover. Note that the “size” does not refer to the speaker’s actual physical size, but rather to the ability of the speaker to reproduce low-frequency information. If your speakers at any position are traditional full-range models capable of handling the full audio spectrum, select LARGE. These speakers are called “large” since the low-frequency drivers required to play bass without strain or distortion are typically eight to fifteen inches in diameter, in turn making the speaker cabinet larger than those with small (or no) low-frequency drivers. When the speakers at a particular position are smaller frequency-limited speakers that do not have the ability to properly reproduce low-frequency sounds, select

SMALL.

At all speaker positions except for the front left/right speakers, you may also select NONE. This setting tells the system that no speakers are present at that position, allowing the AVR to select the correct sur- round modes that are compatible with the number of speakers installed. For example, in order to use the Dolby Digital EX, Dolby Pro Logic IIx, DTS-ES, Logic 7/7- channel and “7 Stereo” modes, you must have either LARGE or SMALL entered as the setting for the BACK SURR channels.

When LARGE is selected for any channel, a full- range signal will be sent to the speaker outputs for that channel. For all speaker positions except the front left/right, when LARGE is chosen, no derived sound will be sent to the subwoofer output, although in all cases the special low-frequency effects (LFE) signals available on 5.1 or 6.1 digital programs will always be sent to the subwoofer output.

When SMALL is selected for any channel, you may also enter a setting for the crossover frequency at which sound is divided between the frequency above which sound is sent to the channel’s speakers and below which sound is sent to the subwoofer. When configuring a “small” speaker, choose the setting that has the frequency closest to that of the lowest fre- quency the speakers in question are capable of han- dling. If one of the six available crossover points does not match, select the one that is above, but closest to, the speaker’s low-frequency limit.
