Digital delay module for S10 DP and S20 DP subs. Delay time ranging from 1.5 to 99.5 ms. It allows you to align subwoofers to full-range speakers with a calculated delay time and/or create special configurations, such as cardioid and and-fired, with subs not equipped with built-in delay. It comes up with delayed XLR output to connect other subs with the same delay time.
