Presonus Eureka Channel Strip
Product Description for the Presonus Eureka Channel Strip
The Eureka channel strip features a Class A transformer-coupled mic preamp with variable impedance as well as a saturation knob for tube saturation emulation.
The Eureka sports a compressor with variable threshold, attack, release and gain makeup. It offers a soft knee compression mode, as well as a high-pass filter on the sidechain for frequency dependent compression, which is useful for de-essing and other frequency specific compression applications.
The Eureka, complete with an audio transformer on the input stage, offers a fully-parametric three-band EQ with overlapping bands and switchable staging for the EQ and compressor, enabling you to swap the order of the EQ and compression.
The Eureka has instrument, line and microphone inputs as well as switchable gain reduction for the VU meter, dual outputs (TRS and XLR) that can be used simultaneously and an optional digital output card capable of up to 24-bit 96khz output on AES/EBU or S/PDIF. In addition, the unit has a 48-volt phantom power unit with an 80Hz rumble filter, a -20dB pad, a phase inversion button and balanced send and return jacks for inserting outboard gear.

Does the job well
Review by Dogstarr1
The impedance selection is a nice feature and actually pretty fun to play with, it has a number of settings, which can really make a difference, particularly with dynamics and ribbons ( worth a try on tube mics also) , sonically, it can increase the output level of your mic and it\'s sort of like pre-EQing the input.
I found the saturation less inspiring, just sort of gives it that \"dragged a blanket over the speaker sound\", you know that sound that usually you rave about it going away with some piece of gear, or another...well Presonus gave it to you on demand!
Though in all fairness, set at around around 25% (or less) seemed to slightly smooth things, though I found the extra \"haze\" added up quickly while tracking and you\'re probably better off running through a real tube in another device in the loop.
The compressor was a real surprise, actually a good one, sounds and works like your typical DBX VCA-type, clean, quick and very versatile, while not as intuitive as a 160A ( it has way more controls), the end-product is comparable.
The EQ section is 3 band, parametric, and it is clean, but the highs can get a touch too \"crisp\", bordering on the dreaded \"harsh\", of course, this is typical of SS gear (until you spend 4, or 5 times as much), so just be careful that when you mess with the EQ you don\'t overemphasize that tendency too much trying to catch \"air\" and you should be fine.
