INITIAL SETUP

Setting the Speaker Crossover menu correctly ensures that your speakers 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 LFE line sets the frequency for a low-pass filter that determines 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 determine which group is set to the highest frequency. Move the cursor to the LFE line, and use the /Buttons to select that speaker group. If all three 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 BACK TO MANUAL SETUP line and press the Set Button to return to the Manual Setup menu.

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, sometimes 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 Setup menu, move the cursor to the DELAY ADJUST line and press the Set Button to display the Delay Adjust menu.

See Figure 43.

Figure 43 – Delay Adjust Menu Screen

This menu requires you to enter the distance from each speaker to the listening position, which you measured in Step Two – Measure Speaker Distances and noted in Table A3 in the appendix.

The default unit of measurement is in feet. If you wish to change the unit to meters, move the cursor down to the UNIT line, and use the /Buttons to change the unit to METER.

Use the /¤ Buttons to move the cursor to the FL (front left) line; then use the /Buttons to change the measurement as needed. Use the /¤ Buttons to move to each speaker in turn – CEN (center), FR (front right), SR (surround right), SL (surround left) and SUB (subwoofer).

DELAY RESET: This line is used if you wish to reset all of the speaker delay settings to the factory default of 10 feet (3.0 meters) at once. Use the /Buttons to change the setting of OFF to ON. If you change any speaker’s setting, this line will automatically revert to OFF.

A/V SYNC DELAY: This line allows you to compensate for a situation in which one of your source devices, or your video display, introduces a significant amount of video processing that causes the audio and video parts of the signal to lose synchronization. This is known as a “lip sync” problem. You may delay the audio for all channels by up to 80 milliseconds to compensate.

NOTE: We recommend that you adjust the A/V Sync Delay using the Delay Button on the remote, rather than in this menu, so that you can view the picture while adjusting the audio delay. With the program playing, press the Delay Button, and the A/V SYNC DELAY message will appear on the front panel and in the semi-OSD display. Press the Set Button to display the current delay setting, and use the /¤ Buttons to adjust the setting until the picture and sound are back in sync.

Move the cursor to the BACK TO MANUAL SETUP line and press the Set Button to return to the Manual Setup menu, or press the OSD Button to exit the menu system.

You may adjust the delay settings without using the on-screen menu system. Select a surround mode that uses all of the speakers in your system. Press the Delay Button on the remote to display the A/V SYNC DELAY message. If you wish to adjust A/V Sync Delay as described in the above note, press the Set Button to select it. Otherwise, use the /¤ Buttons to scroll through the list of all loudspeakers in your system. Press the Set Button when the speaker you wish to adjust is displayed, 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.

Step Four – Output Level Calibration

This is an important step in the configuration process, and should not be skipped.

Many people assume that during a presentation, such as a movie, the surround channels will sound as loud as the front channels. However, this is usually not the case, as directors often steer only ambient of background sounds to the surround channels. For example, during a
