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 Condenser/Low Price

By BackdropGuitarist

from Dallas, TX

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

When starting to build my home recording studio, I was looking for something affordable that I could record some vocals and acoustic guitar with and still have a good sound. I was reccomended to the ST55 and I'm loving it. After 6 months of use, it has definately paid for itself. All of my friends are surprised by the awesome recordings I make now. The -10dB switch and the low roll-off are nice touches, and I like the box, although I wish it was a hard case like the ones that come with other condensers.

Well Worth The Money

By Gbluesy

from N.C.

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

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.

Good Value For This Price Range

By Ernest Parker

from Providence, RI

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

I love this mic. Beat my old one without a doubt. This is the best mic in this price range. You get the most bang for your buck. Low noise, considerable sensitivity, and warmth. sounds great with my Tubepre and Firewire Solo. I can't wait to upgrade to an st77!

Good first studio mic

By Joseph J.

from Tulsa, OK

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

I picked this up at my local GC for 2 bills, though I was a little iffy on having only one polar pattern to play with. Got it home, took off my SM-58 (I'm cheap), put this in its place, and fired up the home rig to see how it sounded, after flat-lining my 1604's parametric, and bringing up my DAW software. I'm used to recording in a noisy environment, and with the hi-pass filter and attenuation switches, it's almost like I'm recording in a proper studio. Gonna have to pick up another one of these ASAP.

Most clear mic I've ever had

By William Johnson

from Baltimore, MD

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

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.

Well Worth it

By Gbluesy

from N.C.

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

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.

Great sound for low cost!

By G-Hef

from The Nasty Nati!!

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

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.

Worth Every Red Penny!

By Damion Morse

from Farmington Hill, MI.

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

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.
