PreSonus Audio Professional Channel Strip

PreSonus Audio Professional Channel Strip

The Eureka is a professional recording channel strip containing a discrete class A transformer-coupled microphone preamplifier, 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 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.

The Eureka is loaded with microphone, line and instrument input so you can use it as a front end preamplifier for recording with microphones, guitars, keyboards, synths as well as a compressor/equalizer on a single channel during mixdown. The Eureka also has 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.

An optional 24 Bit/192kHz digital output card (AD192) is available for the Eureka to further optimize sonic performance. The Eureka's AD192 digital output card is loaded with both SPDIF and AES/EBU outputs, word clock I/O as well as a balanced TRS line input so that only one output card is nessesary when using two Eureka's in stereo or dual mono situations.
