The PreSonus Eureka is a professional recording channel strip containing a discrete class A transformer-coupled microphone preamplifier, Fet compressor, and three-band parametric equalizer.
The microphone preamplifier features variable input impedance so that the Eureka can be matched and tuned for all types of microphones and recording applications. The Class A transformer-coupled microphone preamplifier also features Saturate which adjusts the drain current on the input Fet amplifier to simulate of the effects of tape saturation and tube warmth.
The Eureka's ultra fast Fet compressor has both soft and hard knee compression as well as a separate make up gain stage and hi-pass side chain compression to deliver hard pumping to ultra transparent compression and everything in between. The Eureka's 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 Recording Channel Strip Mic Preamp
