Empirical Labs DocDerr

The Empirical Labs DocDerr is a brand new API 500 series multi-purpose channel strip. This breakthrough tone enhancement module houses six different sections of digitally controlled analog processing at an extremely affordable price point.

A super low-noise preamp capable of line or 16 dB of “instrument” gain is followed by four sections of EQ offering one selectable high pass and three parametric bands. The dynamics section provides renowned Empirical Labs compression at an unprecedented price, as well as a tape emulation circuit to soften high frequencies and clips.  A “Mix” knob allows the user to blend the uncompressed EQ’s signal with the compressed and saturated signal. Inputs and outputs are DC coupled, and the output can be switched between single ended or differential, yielding + 6dB of gain.  A “Bad!” hard clip indicator monitors most every section for internal clipping.

“I couldn’t be more delighted with this piece,” says ELI founder and designer Dave Derr. “It has an interface and feature set unlike anything else on the market.”

The DocDerr model EL-Rx is available with either horizontal or vertically oriented front panel configurations.
