Although personal preference is the ultimate guide, you typically increase the delay to speak- ers located closer to the seating area and de- crease the delay to speakers located farther from the seating area.

Start by measuring the distance from your seating position to each speaker. The speaker farthest away should receive no additional delay. Each of the other speakers will receive one millisecond of delay for each foot (30 cm) closer to you than the farthest speaker. For ex- ample, if the left front speaker is farthest away at 13 feet and the left rear speaker is 8 feet away, you should add 5 milliseconds of de- lay to the left rear speaker. Continue setting delays for each speaker until you have com- pensated for each speaker that is closer to you than the farthest speaker.

The delay times for the surround speakers are set longer for Dolby Pro Logic II mode than in Dolby Digital/DTS mode. When you change delay setting for Dolby Digital/DTS, the de- lay time for Dolby Pro Logic II will automati- cally be set for MUSIC or CINEMA/EMULA- TION modes.

The available settings for the CENTER chan- nel (Dolby Digital/DTS only) are 0ms, 1ms, 2ms, 3ms, 4ms, and 5ms. For SURROUND (Dolby Digital/DTS), the settings are 0ms, 5ms, 10ms, and 15ms. For SURROUND (Dolby Pro Logic II), the MUSIC mode settings are the same as the Dolby Digital/DTS settings. For SUR- ROUND (Dolby Pro Logic II), the CINEMA/ EMULATION mode settings are 10ms, 15ms, 20ms, and 25ms. For the CENTER BACK channel (Dolby Digital/DTS only), the settings are 0ms, 5ms, 10ms, and 15ms.

To change a setting, place the highlight on the desired line using the UP/DOWN buttons and use the +/– buttons to increase or decrease the delay setting. To return to the MAIN menu, press the ENTER button. Press the MENU key on the remote to cancel the display and re- turn to normal operation.

The SUBWOOFER SETUP menu allows selec- tion of the subwoofer crossover frequency and independent adjustment of subwoofer level for each surround mode. These settings are memo- rized and engaged automatically each time a music or theater surround mode is selected.

When going to the SUBWOOFER SETUP menu from the MAIN menu, the current surround mode is automatically highlighted. Use the +/– buttons to adjust the subwoofer level (–10dB to +10dB) for the current surround mode.

NOTE: Only the current surround mode can be adjusted on this menu. You will need to change surround modes using the front-panel or remote buttons to adjust a different mode.

We recommend starting with the level settings for all surround modes at the default 0 dB setting during the test tone calibration of the system and for a period of familiarization after that. As you listen to a variety of source material over time, you may notice that certain surround modes consistently produce too much or too little bass from the subwoofer. Use these sub- woofer level settings to adjust the relative bass output of various surround modes.

NOTE: In Dolby Digital and DTS recordings, the LFE channel is used to produce spectacu- lar low bass effects. This LFE channel can generate output 10 dB louder than the other channels, placing considerable demands on your subwoofer system. If you hear distortion or other signs of distress from your subwoofer at loud listening levels, you may consider re- ducing the subwoofer level for the Dolby Digi- tal and/or DTS surround modes. In other surround modes, there is no LFE channel and the subwoofer will only reproduce redirected bass from the other channels, which is not as likely to tax the subwoofer.

The CROSSOVER setting activates a low-pass filter for the subwoofer and a corresponding high-pass filter for all SMALL speakers in the system at the selected frequency. To adjust the crossover frequency, highlight the CROSSOVER line using the UP/DOWN buttons. Then, use the +/– buttons to chose one of the following options: OFF, 40Hz, 60Hz, 80Hz, 100Hz, or 120Hz. The 80Hz or 100Hz crossover points are the most common in home theater systems. However, your best setting depends on the specific speakers in your system.

NOTE: The OFF setting sends a full-range sig- nal to your subwoofer so that you can use its built-in low-pass filter. With the OFF setting, a 100 Hz high-pass filter is activated for all SMALL speakers in the system.

To return to the MAIN menu, press the EN- TER button. Press the MENU key on the remote to cancel the display and return to normal operation.
