This menu, which is reached from the MAIN menu, allows you to set the delay for individual speakers. This ensures that the sound from each speaker arrives simultaneously at the listening position, even when the speakers not all placed at equal distances from the listener.

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 mode than in Dolby Digital mode. When you change de- lay setting for Dolby Digital, the delay time for Dolby Pro Logic will automatically be set 15ms longer.

The available settings for the CENTER chan- nel (Dolby Digital only) are 0ms, 1ms, 2ms, 3ms, 4ms, and 5ms. For SURROUND (Dolby Digital), the settings are 0ms, 5ms, 10ms, and 15ms. For SURROUND (Dolby Pro Logic), the settings are 15ms, 20ms, 25ms, and 30ms.

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.

SUBWOOFER LEVEL Menu

SUB LEVEL

DOLBY: +1

DTS: -2

STEREO: +5

MUSIC: +3

ENT KEY=MAIN MENU

+/– KEY=change

The SUBWOOFER LEVEL menu provides in- dependent 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 LEVEL menu from the MAIN menu, the current surround mode is automatically highlighted.

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.

Use the +/– buttons to adjust the subwoofer level for the current surround mode. To return to the MAIN menu, press the ENTER button. Press the MENU key on the remote to cancel the display and return to normal operation.

TEST TONE Menu

TEST TONE

LEFT: +1dB

CENTER: -1dB

R SURROUND: +5dB

L SURROUND: +4dB

	SUBWOOFER: +9dB
ENT	KEY=MAIN MENU	UP KEY=up
+/–	KEY=change	DWN KEY=down

This menu uses test tones to set equal volume levels for all speakers (left front, center, right front, right surround, left surround, and subwoofer) to ensure proper surround sound reproduction. Setting the output levels using the test procedure provides the most accurate adjustment so that digital surround sound material will be reproduced as it was intended.

To access this menu and perform the test tone calibration, you must be in one of the surround modes. To do this, press any of the MODE buttons except 2CH. Then, enter the ON- SCREEN DISPLAY menu system and select TEST TONE from the MAIN menu to reach this screen.

When you enter the TEST TONE menu, you will hear a test tone coming from the highlighted speaker. Highlight different speakers by moving the cursor to the desired line using the UP/ DOWN buttons. The test tone will shift accord- ingly to the selected speaker.

While seated in the normal listening location, switch the test tone to the various speakers. Using the loudest speaker as a fixed reference, listen to hear if any other speakers are notice- ably louder or quieter. If so, adjust that speaker’s volume levels up or down (in 1dB increments) to match using the +/– buttons. Continue switch- ing among the speakers and adjusting until all speakers are the same volume.

NOTE: This calibration will be more accurate using a sound pressure level (SPL) meter in- stead of relying on your ear. Set the meter to its SLOW response time with C-weighting and hold it away from your body. Adjust the lev- els until the meter provides the same reading for each of the speakers in your system.

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