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. 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.
