PreSonus Eureka, Channel Strip

"PreSonus has a winner on their hands with Eureka. It’s a well-built, high-performing channel strip at an affordable price. At under $700 retail, Eureka stands out in the crowd. Its specs and feature list are cool — transformer-coupled input, flexible signal path, good processing capabilities, etc. — but its outstanding attribute is its open, detailed sound. It would make a great choice as a front-end for a DAW." - EQ Magazine

"You will not find as many features on a channel strip of this quality for this price anywhere else." - TapeOp Magazine

"Vocals tracked through the Eureka were stunning. The preamp stage is quite transparent, yet natural sounding. When using the Eureka to amplify other sources, the results were consistently impressive." - Stefan, Christian Musician Magazine

"Well, I guess it doesn't pay to judge a pre-amp by its cover/price. The sound was way above what I was expecting. This is really great for vocals, bass tracking or re-amping. The compressor is worth the price of the unit alone." - Sean, CA

 

The Eureka Pro Recording Channel

 

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.
