PreSonus Eureka Pro Recording Channel Strip Microphone Preamp
No longer available at zZounds
The PreSonus Eureka is a recording channel strip featuring a discrete class A preamp, FET compressor, and three-band parametric equalizer.
Overview
Plug a microphone, instrument, or line-level input into the Eureka preamplifier, or insert it 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. The Eureka gives you the sonic performance and control you need in the real world to produce professional-quality audio.
- Variable microphone input impedance
- Variable SATURATE control (simulates tape saturation and tube warmth)
- Fully variable compressor with hi-pass side chain
- 3-band fully parametric equalizer
- EQ pre or post compressor
- High headroom output section
- Very low noise design
- Internal power supply
- Optional 24-Bit/192k digital output card
- Transparent, wide range performance
The 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… read more 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 3-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. read less

"Easily competes with "high-end" units."
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
I've been tracking vocals (with a Neumann TLM103), electric bass, acoustic guitar, and classical guitar through this and am considering getting another one just for convenience.
I would absolutely replace it with another one without even thinking about it.
Sound
I saw a review mentioning the lack of a tube. The Eureka has a "Saturation" knob which provides even harmonics, just like a tube. Sure, you can't yank it out and try other circuitry (as you would be able to try different 12AX7's or 12AU7's on other devices), but this unit is hard to beat, even with more expensive units. I'm not crazy about the eq, so I leave it flat and use my Neve eq's from my UAD-1 Ultra Pak. I recorded my bass at another studio via an Avalon and then recorded at home via the Eureka and found that the Avalon made it more muddy than warm; it could have just been the settings applied by the engineer.
Features
Dual balanced out (great for monitoring with one while recording with the other), impedance matching on XLR input (missing from Focusrite and Avalon), assignable meter (output/reduction), phantom power, phase inversion, low cut - the stuff you would expect (digital is optional).
Ease of Use
You don't need a manual, unless if you've never seen a channel strip before.
Quality
Rugged design, 1U, no wall-wart, metal knobs.
Value
At this price,… read more you can get 4 of them instead of one Avalon. This unit is not *cheap*; it is *inexpensive*.
Manufacturer Support
Never needed it.
The Wow Factor
Visually appealing, although the Mindprint is even prettier.
