Readily retrofitted for S10 and S20 subwoofers, the Subwoofer Digital Delay compensates for timing differences between flown arrays and stacked subwoofers, particularly when subwoofers are sited in front of the array. Three countersunk knobs adjust delay time.
The SDD module comes with a Bypass switch that disables the delay function, and an XLR output that connects further subwoofers to the SDD module.
Combining the SDD module with S10 subwoofers also lets you set up a cardioid bass system that attenuates rearward directed sound waves and bundles low-frequency sound waves radiated forward.
