3xSlew

pcb & panel $20 | kit $85 | built & tested $125

3xSlew provides three slew limiters in just 6hp. One slew limiter has independent controls for rise and fall time, while the other two each have one control for bidirectional slew time. Each slew limiter can be switched between linear and logarithmic response. Inputs are normalled so the module can also be used as a buffered multiple. 3xSlew accepts all signals.

Available as a built module or a beginner-friendly DIY project. All components are through hole and easy to source.
