DriveRack Section 5 ® Detailed Parameters a level that is lower than -10dBu is left at the same signal level. Light compression is where only the loudest parts of the signal go over the threshold. Very heavy compression can be achieved by setting the threshold low enough that almost the entire signal content is over the threshold. - Page 27 DriveRack Section 5 ® Detailed Parameters Units - Seconds, Feet or Meters Selects the unit of measurement for the delay. Length Sets the amount of Speaker Alignment delay time. Delay times include: Seconds- 0.00-10.00 ms, Feet- 0.00-11.3 and Meters - 0.00-3.43. Fine adjustments are made in .02 ms increments. Coarse adjustments are made in .21 ms increments.
