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.

Features

• 500 Series multi-purpose tone module

• Six digitally controlled sections of analog processing

• Frequency response - 3 Hz to 180 kHz on eq section (-3 dB points)

• Dynamic range - 120 dB from maximum output (.5%THD soft clipping) to minimum output; noise floor with Mix on 0 is typically – 91 dBu

• Distortion range - between .0006% and 10% at 1 kHz, depending on mode and settings
