DocDerr 500-Series by Empirical Labs Vocal Demo - AES 2011

Empirical Labs introduces the DocDerr which is an 500-Series multi-purpose channel strip that fits in API style lunch boxes. The unit houses six different sections of digitally controlled analog processing and offers four sections of EQ. A "mix" knob allows the user to blend the uncompressed EQ's signal with the compressed and saturated signal. The equalizer offers one selectable high pass filter and three parametric bands while the dynamics section has tape emulation circuit to soften high frequencies and clips. Call SoundPure for more details on this cool new device from Dave Derr. 888.528.9703. or 919.682.5552.

Manufacturer's Description from Empirical Labs

One of the newer members of the Empirical Labs family is the DocDerr, a 500 series multi-purpose tone enhancement module that houses six different sections of digitally controlled analog processing.  With over two years of meticulous development and testing behind it, the DocDerr provides an unprecedented combination of power and musicality in a compact, easy to use format. Empirical Labs' first compressor in the API 500 format.

An extremely low-noise preamp capable of working with line level or instrument level signals, is followed by four sections of EQ combining a two position high pass filter with three parametric bands, each with its own set of carefully tuned frequency presets.  An internal jumper can turn the DocDerr into an unparralled instrument preamp with 16dB of gain, ideal for acoustic guitar, bass, synths, exotic plucked instruments, etc.

The versatile EQ is followed by a unique dynamics section which offers renowned Empirical Labs compression at an unprecedented price, and an extremely musical tape emulation circuit that softens and tames high frequencies and transient spikes.  We believe it’s the best single knob “knee” compression available in this format.

One of the pivotal features of the DocDerr is the “Mix” knob which allows the user to blend the uncompressed EQ’s signal with the compressed and saturated signal.  This parallel compression technique, used by top recording and mixing engineers for many years unlocks a whole world of sonic possibilities.

Like all ELI 500 series modules, the EL-Rx is available with either horizontal or vertically oriented front panel configurations, and is “Linkable” for using our famous compression on stereo sources.

The DocDerr is ideal for tracking, for fine-tuning tracks during mixing, or as a killer solution for the gigging "acoustic" musician in search of studio quality tone control. It is indeed a Tone Doctor…err… DocDerr.

About Manufacturer

Empirical Labs Inc. (ELI), designs and produces professional audio equipment and software. This includes equipment used in recording studios, live sound, broadcast studios and other audio production facilities etc. We also make software for digital signal processors. Most of you are here because you have heard about or used our Distressor. This product, which is our first hardware product, was designed in 1994, tested and revised for several years, and released in early 1996. The Distressor is the first in a series of audio products from ELI that will offer original features, ease of use, long product life, and a very musical audio path. Empirical Labs was started in 1988 and functioned mainly as a recording studio and electronics consulting firm. The founder, Dave Derr, was also employed at the time by Eventide as an audio engineer. Dave was part of the core design team for the H3000, H3500, and DSP4000. His experience at Eventide proved valuable for his later work. While working alongside Ken Bogdanowicz and Bob Belcher (both now at Wave Mechanics), Dave was exposed to great engineering and the modern world of digital signal processing (DSP).
