Key Features
  • Six Sections of Processing
  • 3x Parametric Bands of EQ
  • 1x High Pass Filter
  • Aggressive Compressor Circuit
The DocDerr EL-RX DUO from Empirical Labs is a horizontal pair of multi-purpose tone enhancement modules preinstalled in the EL500 rack that houses six different sections of digitally controlled analog processing. The DocDerr features a low-noise preamp capable of working with line level or instrument level signals, 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 unparalleled instrument preamp with 16 dB of gain, great for acoustic guitar, bass, synths, exotic plucked instruments, and more.

EMPIRICAL LABS RX DUO Overview

The DocDerr EL-RX DUO from Empirical Labs is a horizontal pair of multi-purpose tone enhancement modules preinstalled in the EL500 rack that houses six different sections of digitally controlled analog processing. The DocDerr features a low-noise preamp capable of working with line level or instrument level signals, 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 unparalleled instrument preamp with 16 dB of gain, great for acoustic guitar, bass, synths, exotic plucked instruments, and more.

The EQ is followed by a dynamics section which offers compression and a musical tape emulation circuit that softens and tames high frequencies and transient spikes. The DocDerr features the Mix knob, which allows the user to blend the uncompressed EQ's signal with the compressed and saturated signal. The DocDerr is great for tracking, fine-tuning tracks during mixing, and studio quality tone control.

The EL500 rack features a quiet power supply and offers both XLR and phone rear panel inputs and outputs. In addition, a 1/4" instrument preamp/direct box input is provided on the front panel, which will automatically switch the left 500 module's input to this front phone jack once something is plugged into it. Switches to link compressors and engage a 48V phantom supply are also provided.

DocDerr Module

Low noise line input, or instrument preamp, with compression and six digitally controlled analog sections of processing
Four sections of equalization including one high pass and three parametric bands
Complex compressor envelope generator that is fast, yet musically saturates at high gain reduction and features a program dependent release
Saturation circuitry that scrunches the highs, allows hotter levels, and uses filtering combined with germanium clip circuitry to soften loud high frequencies
Mix control to allow user to blend an uncompressed equalized signal back in with the compressed saturated signal (when on 0, only the equalized signal is put out)
DC coupled input and outputs
Selectable single ended or differential output (adds 6 dB gain)
Traditional and digitally controlled analog
Hard clip indicator lights illuminate when the sound level is within 1 dB of hard clipping and monitors many sections for internal clipping
All metal film and Roederstein resistors in the audio path
