XQP 531A Optical De-esser
$498

XQP 531A Optical De-esser.

The XQP 531A Optical De-esser is the newly designed upgrade to the 531 optical de-esser, which was the original 500-series version of the Dane #31, developed in the mid-90's. Selectable VACTROL or Silonex opto-isolators (Soft and Clean modes) provide sibilance reduction in either the classic style or the more subtle, cleaner style.

The side chain now adds a fourth, lower frequency (W) to the improved high pass filters for isolating sibilant content. This HPF design allows the user to select the bottom of the frequency range of potential sibilance resulting in any sibilant above that point being affected.

Design changes of the 531A also include the new, smaller knobs in a revised color scheme, illuminated In switch, and removable stainless side panel for easier servicing.

Availability subject to availability of VTL5C1 optos.

"Best de-esser ever!...These work so well; musical and elegant - since we're talking de-essers, that says a lot!"

User Comments (531)

"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

"It's fantastic. Far and away the best de-esser I've ever used and I've tried a bunch, both hardware and software. I was able to set it up very easily and quickly to remove just the right amount of sibilance without overdoing it or still fearing distortion down the line."
David Boothe

"De-essers are subtle things (until all of a sudden they're painfully obvious) but the XQP 531 is a wonderfully effective & useful tool...simple to operate and surprisingly intelligent in its filtering. Bottom line - it works."
Neil Pike

"Wow, it is really fantastic. Very elegant sounding. Very natural...Reminds me of how much I hate in the box de-essing. And I didn't want to be reminded."
