Re: Whelen WPS-2907 controller

Wed May 31, 2023 4:53 pm

A Whelen controller would be harsh on the Federal Signal drivers, they aren't made for that. However, it *has, been done. If you really wanted to go at it(which I just wouldn't recommend), you'd have to wire 4 100W FS drivers in parallel to the output to one of the Whelen controller's 400W amps.
I own: One complete SiraTone, another SiraTone control module, a 1600W MC, 2 old ATI controllers, 2 round ATI horns with drivers, a ATI-DSA 4 thing, a Federal Signal FC, AR timer and Siratrol, and a small CD&F.
