XQP 2531 Optical De-esser - Special Edition

The new 2531 special edition Optical De-esser.

In celebrating 25 years since Dane's first de-esser design, a brand new optical de-esser, the 2531, is now available. Borrowing some of the Lima audio design features, this new 500-series module features all rotary switch control, NKK knobs, NKK UB IN switch, and dual thumbscrews.

A range switch associated with the Reduction control allows for 22 level steps by switching the Reduction rotary switch between two halves of the total range of control.

Also included in this new model is a new 3-position Sidechain Feed switch to select either feed-forward (traditional), feed-back, or a blend of the two.

The plan is to build only 25 of these modules.
