PreSonus Eureka Preamp and Compressor is a professional recording channel strip containing a discrete class A transformer-coupled microphone preamplifier, FET compressor, and three-band parametric equalizer. PreSonus Eureka comes with variable input impedance so that the Eureka can be matched and "tuned" for all types of microphones and recording applications. This Class A transformer-coupled Mic Preamp also features "SATURATE" which adjusts the drain current on the input FET amplifier to simulate of the effects of tape saturation and tube "warmth".

PreSonus Eureka sports a compressor with variable threshold, attack, release and gain makeup. It offers a soft knee compression mode, as well as a high-pass filter on the sidechain for frequency dependent compression, which is useful for de-essing and other frequency specific compression applications. The three-band fully parametric EQ gives you variable Q (bandwidth) on each band as well as an EQ pre COMP switch to put the EQ before the Compressor in the signal path. The equalizer has overlapping frequency selection on each band for total tonal control and shaping.

PreSonus Eureka has microphone, instrument and line inputs so you can use it as a front end preamplifier for recording with guitars, keyboards, microphones, synths as well as a compressor/equalizer on a single channel during mixdown. PreSonus Eureka microphone preamplifier gives you the balanced send and return jacks so that you can insert your favorite outboard processor before the compressor/EQ to further enhance and customize your sound.
