A more affordable way to record high-quality audio.

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.

Great Value

By 

from Boise, Idaho

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

I have owned one ST55 for a couple of years and have used it to record drums overhead, acoustic guitars, harmonica and electric guitar amps to record my rock/blues band. The clarity and frequency response is excellent (great cymbal highs, full/warm voice range, sweat acoustic guitar). I have also used to record my church choir voices with excellent clarity results (people gets amazed at being able to understand the lyrics!) as well as for voice/accoustic guitar solo performances. I'm really pleased at how well both were recorded. I have paired itwith both my Zoom H4n recorder and my Motu 828 Mk3. I think that from begginers to serious amateurs will be very pleased with this mic. I'm looking to buy a second one to record two full stereo channels on my H4n and migtht get the multipattern one for more versatility.

Excellent vocal mic for the price

By 

from Los Angeles, CA

Comments about Sterling Audio ST55 Large Diaphragm FET Condenser Mic:

I use this mic for vocals and acoustic guitar, and it sounds excellent. Great "breath-y" modern vocals are acheivable with it, and it has a warm sound in the mids with crisp highs. Bass is easily controlled through proximity, and the high pass filter really helps with boomy dreadnought acoustic guitars. This is a work horse mic - very adaptable to many recording situations. If you only own one mic for vocals, this would be a great choice. If yo only own one mic period, start with an SM57 and make this your second.
