Review: Great quality, great sound, a professional preamp you will absolutley love! - I am very thrilled to have received this product, after the bitter disappointment of the DBX. There is no comparison. The price you pay corresponds to the quality. Presonus is an American brand, recently acquired by Fender. So it's no joke. In the package there is a manual, a guide for musicians about the production of records and marketing (I really appreciate !) and the power cord with a small transformer, which has a handy switcher like the one of the bedroom lamps. As I said the build quality of the material used is high, the color is a nice matte blue, it has a fan for the reaction above, which is very useful to avoid overheating. Rack or desk placement. It's not bulky: I have a very narrow desk and it fits beautifully. Furthemore, the knobs are elegant but very solid, and turn easily. We find: instrument input on the front, TRS output and microphone input on the back. The switch off button is on the back too, but it is not a problem for me, as there is the switcher on the power cable which is very handy. The effects are, as advertised, compressor, saturation, equalizer, phase inversion and there is a knob for output gain and preamp gain. Since there is also a guide with standard parameters for EQ and compression in the manual, it is easy to play even for a novice. Tried with a Yamaha AG06 audio interface/mixer, quite old and cheap. The difference in terms of sound, and gain, is huge. Never heard my voice like this before, maybe just once in the record studio (but they charge.. ) Finally, I have not encountered any kind of problem or imperfection. More importantly, the unit is completely, but I mean completely silent! For those looking for a faithful and clean sound, but which can also be manipulated towards a warmer and more full-bodied sound, and have professional studio quality at an affordable price. Highly recommended.
Review: The best sound from my SM7B Mic to date! - I previously had a Behringer Ultrapro preamp run through a Alesis Compressor / Gate and Behringer Mini EQ. There was a hiss which I thought was normal and it turns out it wasn't the Behringer causing it. Aiming to rid of all that gear, I bought a 'channel strip' (Pre, Compressor, EQ in one unit) which is the 'Presonus Studio Channel'. My audio interface is a Steinberg UR242. Not only did The Studio Channel rid of the hiss, it took the sound of my already good sounding SM7B to another level. The EQ section comprising of a total of eight knobs for low, mid and high frequencies, allowed me to increase the bass in my voice and add an element of brightness - might like the typical 'radio voice sound' which was the goal! The compressor does it's job for me for my voiceover work and as mentioned the pre is quiet. Notable hiss doesnt come into play until you turn the gain right up. I also bought a Cloudlifter and later a Soyuz Launcher which helped me increase my mic signal whilst allowing me to turn down the gain even further. My sound quality has increased a lot as a result buying the Studio Channel alone. What's more, I just sold me old gear to pay for it. If you're looking for a simple, effective solution for an all in one pre, compressor and EQ, this seemingly represents one of the best choices you can make!
