Unlock shelves powerfull full-blown 12dB filters with the Xpander. Output: 2xHP/2xBP/2xLP.
Shelves’ two parametric sections are, behind the scenes, full-blown 12-dB multimode filters. The expander panel gives you access to their low-pass, band-pass, and high-pass outputs. Adjust the parametric section’s frequency to control the cutoff of the filter, and the Q factor to control its resonance.
