Overview

The Sterling Audio ST55 is an FET condenser microphone that employs a large capsule with an ultra-thin 3-micron evaporated gold Mylar diaphragm. The ST55 mic is built with an exclusive process that extends high frequencies and improves details and depth on both vocal and instrument recordings. The FET Class-A electronics provide smooth, warm sound.

Sterling Audio microphones employ several advanced technologies that separate their large-diaphragm condenser mics from the rest of the pack.

One of the more important advancements is their Disk Resonator system. With it, Sterling Audio is uniquely able to compensate for the 14kHz frequency roll-off that is inherent in large diaphragm mics. As any good audio engineer knows, this deficiency translates to a lack of sparkle from high-frequency sound sources.

Other manufacturers have typically solved this problem by cutting other frequencies and then increasing the entire signal to help even out the frequency range. Unfortunately, this results in increased noise.

Disk Resonator Technology incorporates a brass umbrella that protrudes from the center of the diaphragm in Sterling Audio's ST55 microphone. It gently boosts the diaphragm sensitivity to shorter sound waves, allowing it to respond more accurately to those all-important higher frequencies. The result is optimal sensitivity, full frequency response, and a low signal-to-noise ratio.

Another piece of audio wizardry comes in the form of the ultra-thin diaphragm membrane made of Mylar. While most modern condenser diaphragms are 6 to 12 microns in thickness, Sterling Audio, in association with 3M, has produced a highly resilient Mylar that measures a mere 3 microns. This allows the ST55 to deliver an extraordinary degree of sensitivity.
Requires phantom power.

The ST55 is a top performing microphone at a humble price. I bought a used one during a recent stay in the United States. Out of curiosity, not because I needed another mike. First thing you do when you buy a microphone is unscrew it to ascertain it's Chinese allright. Then of course you set it up and perform a listening/recording test. You decide if you like what you hear when listening to the mike alone and in comparison to other microphones, in (their) various applications. Surprisingly, considering its affordability, the ST55 represents an immediate advance over conventional condenser mics in its price range. It is quiet and clear, while the highs are not overpronounced and in balance with the rather warm midrange and very convincing low end. And it doesn't stop there. I have gone as far as putting it alongside the best multi-purpose microphone I have got, regarded by many the king of condensers, which is my Neumann u47. Leaving the technical differences what they are, the ST55 holds up more than nicely, compared to top-end. I rate it excellent.

I was recently surprised to see this mic as it is obviously a a renamed Groove Tube GT55 right down to the case. A decent Mic for the price, with accurate reproduction, but I find it a little bland for vocals, no sizzle. The bass roll-of and 10 db attenuation are nice features at this price. Think the RODE NT1A provides better sound for the same price

Great microphone

By john summers

from Houston, TX

Picked up this microphone to use to record a group of 8 men singing our National Anthem acappela. It worked fantastic. We are looking forward to trying it live on other acappela songs. AND the price was right. I do not think you will find another microphone at this price that will perform like this one. If you are looking - don't miss out.

Very Dope Mic!

By Justin Jean

from Atlanta, GA

I bought this mic about a week ago and I'm running it through mogami wire into an art tube pre amp. I don't know a whole lot about mics and stuff but I can say that this mic sounds great. I use it for rap done a little singing into it. It has a nice smooth natural sound and has made mixing a THOUSAND times easier for me. Plus its a very sexy mic in person.

Like Listening to the Future!!

By Lee Louisville

from Jackson MS.

A real good price for home studio. I've owned it for about two years now and no defects recording is crisp even without the studio foaming. If you are looking for really good mic Sterling Audio is the way to go...I just can imagine how the expensive ones sound...Great buy.

Most clear mic I've ever had

By William Johnson

from Baltimore, MD

I cannot speak for all genres of musicians, but for Hip-Hop vocalists (singers, rappers, etc) this mic definitely gets the job done. The vocals the are recorded through this mic come out crystal clear depending on your (Audio Interface/Preamp of course) One the be best purchases I've made for making music.

Worth Every Red Penny!

By Damion Morse

from Farmington Hill, MI.

I can tell you how many home studios I've been to where they have everything but a good mic. So when I decided to build my own studio, the mic was of utmost importance. The only issue was, I had at the time a "shoe string budget". I went to Guitar Center in Southfield, MI. and got introduced to this mic. Best money I ever spent! Now keep in mind that this is by know means the best mic inthe world, but at the price point, it is awsome. It delivers crystal clear vocals and it's rugged enough to last over the years. I've used a few mics to record vocals, but this mic is outstanding in the booth. Get One, you won't be dissapointed.

Well Worth it

By Gbluesy

from N.C.

For starters, it sounds great. Vocals and/or Instruments. I used it for about a month now in many recording tests just to see how well it did and how easy it was to work with as per its sound quality. It works very well. It is warm but not boomy. Although it does have a deep low end it does not overpower the rest of the frequencies. It is just there. Recording a Bass cabinet was surprisingly well. It was maybe a little too clear- LOL. Hear everything that the speaker had to offer. Vocals, it is smooth. You have to respect the distance but that is not the mics fault. The singer should understand where he is and how to sing in a studio. It will give you what you put in front of it. The body is built extremely well and looks great! All in all, it is worth more than I paid for it. Get it! I recommend it.

Well Worth The Money

By Gbluesy

from N.C.

I have been recording live or in my small studio for years now. When I make any efforts to improve my system, I always seem to have the most success when moving up with the mics. Here is one of those successful add stories. This mic has what it takes to be a smooth yet pleasing sound while being an everything mic. It holds it's own all over. It does have that Groove Tube/Sterling way about it so it has earned it's way into my favorite mic list. The fact it does not need the Tube box like the other mics from Grove Tube makes it easier to use. It does not do the siblin or boom thing or favor the source as to what is around it. it just records smooth and you get a very good reproduction of the source as is sounded when it recorded. I like it and I am sure you will be pleased with it also. If you want me to put it on a scale from 1 to 10 ( 1 being best ) I have to say it's a 4 and sometime a 3. Hope that all helps.

Great sound for low cost!

By G-Hef

from The Nasty Nati!!

I dig this mic. I'm very happy with it. I mostly record vocals with it and a little guitar. The ST55 has a warm sound ,and is also very detailed. I'm using it with an ART MP Studio pre that I bought. If you know what your doing you can pull off that pro sound your looking for with this mic, it just takes a little tweaking.

Perfect for podcasting in various locations

By ITRadio

from Twin Cities,MN

I picked this microphone up because I was about to do a live show/podcast recording at a tattoo studio, and needed a decent microphone to pick the client and tattoo artist up. I didn't get a chance to have a test run at it, but I didn't need to. The sound was amazing. I've used this at the tattoo studio, my spare bedroom/studio, and my co-host's duplex and a office building inside a warehouse and it picks up just what it needs to. I have yet to have any major problems with it, and I love it.
