The Ladder 500-Series Ladder Filter from Moog is a 500-series compatible dynamic ladder filter. It features a selectable high- or low-pass filter with adjustable cutoff and a 2- or 4-pole slope, equivalent to 12 or 24dB respectively.
Designed to provide creative EQ and filtering options, the Ladder has variable attack and release times, which allow you to control how fast or slow the envelope opens and closes. The resonance control can accentuate certain frequencies, and is capable of being pushed to self-oscillation for intense effects. The filter's amount control gives you both positive and negative modes, which give you a range from subtle filtering to compression-like behavior. The unit has a hard-wired true bypass for A/B comparison.
Note! This unit requires a 500-series power supply for operation
