"I've been using the XQP 531 for about two months now and I just want to say...It's Awesome!!! It's useful for more than just de-essing a vocal, but when you need a de-esser...it really, really works!!!!!!"
-Tony Shepperd

Based on the Dane Optical De-esser #31, the XQP 531 uses a pair of VACTROL® optoisolators to achieve smooth reduction of sibilance.

The filter in the sidechain is a high-pass design, switchable to three cutoff frequencies. A HPF, rather than a band-pass, allows any sibilant above the chosen frequency to be reduced.

It is our intention to build a smooth, simple, musical device instead of one that is fiddly to operate and difficult to achieve a good sound.
