Product Description

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.

Features:

- Class A high headroom transformer coupled microphone preamplifier
- 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 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. zZounds is an authorized dealer of PreSonus products.

Customer Reviews
4.5 out of 5 (60 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Easily competes with "high-end" units."
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. Feature: 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, 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. Overall: 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.

"If you want your studio to sound like a real studio...start here!"
Sound: This is my first Pre-amp. I researched before I bought (not a lot of money ya know), and people said this is the best for the money....They are right!!! Feature: The Manual is a great starter for setups. I'm like mid-aged, so the numbers on the knobs could be a little larger for view. I have to put on glasses to see well ( I know other people have trouble with them too!) Ease of Use: Manual helps alot Quality: No problems to date. Thought I had a buzz in it, but found that a mic cable was doing the noise (whew...). I have some very hi-end friends who frequent my studio, and they say that my little bedroom sounds like a REAL ROOM! Well, when I first setup, I knew I needed a preamp cause it sounded like a rookie bedroom room. All my recordings came alive and breathed with the Eureka! Value: Got no money! I only need the best value for my bucks! Thank you Prosonus! I only wished that this was available in a stereo strip! Manufacturer Support: N/A The Wow Factor: Impressive facade. But kinda crappy when you fiddle around cause you can't read the knobs. Overall: This made the difference on the front end of my recording projects! Even if you can't program it, follow the manual pre-sets and you'll be way better that when you started...trust me! I got a good sound on vocals and now I don't touch it. It seems to work for everything! Frigging works like magic!

1. We offer the most flexible payment plans in the biz

zZounds offers a number of different installment payment plans that make it affordable and convenient for you to get the gear you really want today, without racking up risky credit card debt.

Other stores offer house credit cards that require you to fill out an application and pass a credit check--and, if you qualify, leave you vulnerable to exorbitant interest charges once the initial promotional period ends. zZounds payment plans are easy to get and simple to use; plus we'll never charge you interest!
