ADVANCED FUNCTIONS

•If you set the front speakers to LARGE, you may select from three possible settings for the subwoofer.

SUB L/R+LFE: This setting sends all low-frequency information to the subwoofer, including both information that would normally be played through the front left and right speakers and the special low-frequency effects (LFE) channel information.

SUB (LFE): This setting plays low-frequency information contained in the left and right program channels to the front speakers, and directs only the LFE channel information to the subwoofer.

NONE: This setting steers all low-frequency information to the front speakers, and no information to the subwoofer output. Use this setting if you have a passive subwoofer, or a powered sub- woofer that you connected to the front speaker outputs.

NOTE: If you are using a Harman Kardon HKTS speaker system, select the SMALL setting for the LEFT/RIGHT, CENTER, SURROUND and SURR BACK lines, and the subwoofer will automatically be set to SUB (LFE).

Move the cursor to the left to select the next submenu.

The speaker sizes may also be configured without using the on-screen menu system. Press the Speaker Setup Button on the remote, and use the ⁄ /¤ Buttons to select the desired speaker group (Front Speakers, Center Speaker, Surround Speakers, Surround Back Speakers, Subwoofer). Press the Set Button to display the current setting for the speaker group, and use the ⁄ /¤ Buttons again to change the setting. Press the Set Button to return to the previous display, or wait a few seconds for the AVR to return to normal operation on its own.

NOTE: The Speaker/Channel Indicators on the front panel of the receiver (see Figure 82) will display the speaker size settings as follows. For each speaker configured as SMALL, a single box will appear in the position for that speaker. For each speaker configured as LARGE, a double box will appear in its position.

If a speaker is configured as NONE, no box will appear. The subwoofer will be indicated by a single box, or no box if no subwoofer has been configured. The letters inside the boxes appear when a digital signal is being received that has that channel discretely encoded. The letters flash when the signal is not present, such as when a DVD is paused. A line will connect the SBL and SBR boxes when a 6.1-channel signal is detected, indicating that the same signal is playing through both speakers.

Speaker Crossover Menu

On the Manual Speaker Setup menu, move the cursor to the Cross- Over line and press the Set Button to display the Speaker Crossover menu. See Figure 85.

Figure 85 – Speaker Crossover Menu Screen

Setting the Speaker Crossover menu correctly ensures that your speakers are properly used so that they sound their best. Although you could skip this step the first time you use the receiver, we recommend that you take the few extra minutes to enter the correct crossover settings.

You may select from seven possible settings: 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz or 200Hz. Depending upon the frequency response of your speakers, which you recorded in Step One – Determine Speaker Size, for each speaker group select the number that matches or is just above the low end of your speaker’s frequency response. You may record the speaker crossover settings in Table A5 in the appendix.

The Subwoofer line sets the frequency for a low-pass filter that deter- mines what information is sent to the subwoofer for playback. Since the subwoofer output combines low-frequency information for all channels, in order to make sure that no information is lost due to different speakers having different capabilities, the subwoofer filter should be matched to the highest crossover frequency used for any speaker group.

Examine each of your speaker-group settings in this menu, and deter- mine which group is set to the highest frequency. Move the cursor to the Subwoofer line, press the Set Button and use the ‹ / › Buttons to select that speaker group. If all speaker groups have the same setting, you may leave the LFE filter at its factory default of the LEFT/RIGHT speaker group.

Move the cursor to the left to select the next submenu.

It is not possible to adjust the speaker crossover settings without using the on-screen menu system.

Delay Adjust Menu

As explained above in Step Two – Measure Speaker Distances, some- times the speakers are placed at different distances from the listening position, which can muddy the sound, as sounds are heard earlier or later than desired.

Even if all of your speakers are placed the same distance from the listening position, you should not skip this menu.

On the Manual Speaker Setup menu, move the cursor to the Delay Adjust line and press the Set Button to display the Delay Adjust menu. See Figure 86.
