Calculating the delay time
The DVD player is set by the manufacturer to play back correctly synchronised Digital Surround Sound. The listening range is defined so that the Surround loudspeakers are located approximately 150 cm closer to the listener than the front loudspeakers, and that the middle loudspeaker is on a line with the front loudspeakers. If you change the position of the loudspeakers you must also adjust the delay time. Choose the setting closest to the calculated value.

SOUND SETTINGS _____________________________________________________________________
Delay time for Digital Surround The distances are calculated in centimetres. Measure the distance from the front loudspeakers and the Surround loudspeakers to the listener�s central position. Subtract the distance to the Surround loudspeakers from the distance to the front loudspeakers and divide the result by 30. This gives you the necessary delay time in milliseconds for the Surround channel. Example: Distance to front loudspeakers � Distance to Surround loudspeakers = 60 cm : 30 = 2 milliseconds 180 cm 120 cm 060 cm

If the middle loudspeaker is on a line with the front loudspeaker, then no further setting is necessary. If the middle loudspeaker is nearer to the listener�s central position, then measure the distance from the front loudspeakers to the middle loudspeaker and divide the result by 30. This gives you the necessary delay time in milliseconds for the middle channel. Delay time for Dolby Surround With Dolby Surround 15 milliseconds are added to the delay time for the Surround channel. If the centre channel is also switched on, then 15 milliseconds are also added to the delay time for the centre channel.
