Delay Settings One aspect of the surround modes is the delay of audio signals between the front speakers and the rear speakers. Each surround mode is factory preset with a specific delay time, but it is possible to individually adjust the delay timing to custom tailor the sound to your individual taste and the acoustic conditions in your listening room or home theater. The factory setting is appropriate for most rooms, but some installations create an uncommon distance between the front and surround speakers that may cause the arrival of front channel sounds to become disconnected from surround channel sounds. To resynchronize the front and surround channels, follow these steps: 1. Measure the distance from the listening/viewing position to the front speakers. 2. Measure the distance from the listening/viewing position to the surround speakers. 3. Subtract the distance to the surround speakers from the distance to the front speakers.

a. When setting the delay time for the Dolby Digital surround mode, the optimal delay time is the resulting figure. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10�5=5. Thus, in this example, the delay should be set at five milliseconds. b. When setting the delay time for the Pro Logic mode, take the result of the subtraction and add 15 to obtain the optimal delay time. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10�5+15=20. Thus, in this example, the delay should be set at twenty milliseconds. The Dolby Digital mode also provides a separate setting for the center-channeldelay mode, since the discrete nature of Dolby Digital signals makes the location of the center-channel speaker more critical. To calculate the delay for the center channel, measure the distance from the preferred listening position in the center of the room to both the centerchannel speaker and either the left or right speaker. NOTE: The Theater, Hall 1 and Hall 2 modes use a fixed, non-adjustable delay time.

If the distances are equal no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker you may wish to reposition the speakers by moving the front left/right speakers closer to the listening position or the center speaker further away from the listening position. If repositioning of the speakers is not possible, adjust the center delay time so that you add one millisecond of centerchannel delay for each foot that the distance to the center speaker lags behind the front speakers. For example, if the front left/right speakers are each 10 feet from the listening position and the center-channel speaker is 8 feet away, the delay is figured as 10�8=2, suggesting an optimal center delay of 2 milliseconds. To set the delay times, follow these steps: 1. Put the AVR35 in the Dolby Pro Logic mode by pressing the Dolby Pro Logic Selector � on the front panel, or by pressing the Surround Mode Selector g on the remote, followed by the � / ¤ buttons h until PRO LOGIC appears in the the PRO LOGIC indicator F lights. 2. Press the Delay button x ı on the remote or front panel. The words S DELAY TIME will appear in the Main Information Display S .
