Rear speaker (left surround) Rear speaker (right surround) Delay times - DVD only Your SACD player is set to correctly reproduce synchronized Digital Surround Sound in a listening area where the surround speakers are about 150cm nearer to the listening position than the front speakers and the center speaker is in line with the front speakers. To adjust for other listening-area arrangements, adapt delay times of the center and surround speakers following: Digital Surround Measure the distances in centimeters from the front speaker plane and from the surround speaker plane to the listening positioning plane. Subtract the surround distance from the front distance and divide by 30. The result is the required Surround Channel delay time in milliseconds. If the center speaker is on the front speaker plane, no center speaker delay is needed. You can adjust the delay time in the "User Preference Settings". See Personal preferences - Sound - Speaker Settings. If, however, it is nearer to the listening position, measure the distance in centimeters between the front and center speaker planes and divide by 30. The result is the required Center Channel delay time in milliseconds.
