Overview

The Sterling Audio ST66 is a tube condenser microphone that employs a large capsule with an ultra-thin 3-micron evaporated gold Mylar diaphragm. Optimized to capture the most definition and detail from all acoustic instruments like piano, drums, and guitars, the ST66 mic's low-noise GT6205M tube in a Class-A triode circuit provides warmth and detail, adding new dimension to vocal and especially instrument recording.

The ST66 uses triode wiring on specially selected pentode tubes to yield low noise and a more realistic dynamic response than their competitors. Its power supply is designed with a load-balancing circuitry that allows cable runs of more than 200 feet with no deviation from optimal performance.

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 ST66 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 ST66 to deliver an extraordinary degree of sensitivity.
Requires phantom power.

In recent years, the onslaught of Chinese made condenser microphones has at least given the home/project studio the 'look' if not the 'sound' of pro studios. Many of these imports are excellent values for the money but still aren't quite up to the standards required for professional recording. The Sterling Audio line of microphones changes all that. I purchased the ST66 with the intent of using it primarily as a vocal mic, wanting the traditional 'warmer' sound found in tube microphones. However, the first application I got to use it on was recording an acoustic guitar. Normally I would have used a small diaphragm condenser to capture the transients and give the guitar more bite on the picking. I was awestruck at the results of the ST66! The clarity, transparency, and the dynamic response resulted in one of the best recordings of guitar I've had in 30 years. I immediately tried it on a squareneck Dobro, and the results were just as stunning. Male vocals recorded using the mic were warm and silky smooth.. the proximity effect that cardioid mics are known for sometimes means that the low end blows out the overall sound.. not so with ST66. By using the high-pass filter, the resulting warmth is enhanced and lets the true character of a voice shine. The 3 micron diaphragm obviously results in a superior dynamic response. Coupled with the class-A tube amplifier and very low self-noise, the ST66 compares (and in my opinion) exceeds the quality of some well-known German mics that one would pay 4 or 5 times the cost of the Sterling Audio. Additionally, the mic features an -10db pad and a switchable high-pass filter. The mic is incredibly solid and well-built. The included shock mount is far superior than that found with most Chinese imports and the power supply is rugged and appears to be built to last. Overall, I cannot find any faults in this microphone other than I now want several more. Take the next step up in recording and try out the ST66. You won't be disappointed.

Mic is fine but not the power supply

The mic seemed to work fine but I have had two power supplies and both are dead. New ones list for $99 so just be forewarn the quality is obviously not here.

      bought this mic. If you do Hiphop or Watever You do in your home studio, buy this microphone. I Have the Avalon 737 and this mic together, and i always turn off the avalon and connect the microphone without it. just the 002 interface and this mic. its crazy i love it. young adults come in the studio i turn on the avalon pretending because young adults and adults love it, but they dont know am not recording them with the avalon and they end up loving it. it's just crazy! your vocal will sit on your instrumental like Pro. I do little EQ bosting High and a high mids like not passing 3 db. For now its my official Hiphop Microphone because the price and Quality. againg its crazy.

          I purchased this mic mainly to upgrade for vocals. I A-B ed it against a Blue Bluebird I've been using for a little over a year and was really surprised. The Bluebird sounded harsh in the upper mids by comparrison. If this mic holds up then it will be a great investment. Have not tried yet on instruments.

          great value studio workhorse

          By mike coffman

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          when i bought this microphone there were not alot of reveiws, and NO REVEIWS for this mic based on hip hop usage.....i run this mic thru my APHEX preamp into my ECHO interface.....im able to acheive a great quality vocal recording that requires little to no EQ and COMPRESSION.....using the SONITITUS suite in sonar X1, i just add a little reverb and very little compression, and my recordings are studio grade and radio ready....i bought the RODE LARGE WINDSCREEN, and it fit perfectly....now i record without the bulky pop filter you would expect.....heres the best part, i disconnected the aphex 207d and this mic was wonderful....there wasnt much difference without the 800$ dollar amp with 100$ aftermarket tube....great mic
          its got all the features you would expect in a studio condenser mic....there is absolutely no HISS or ECHO sounds produced by the phantom power supply.....everything works as described
          build solid....all the connectors are tight and snug.....the cable included from microphone to power supply box is excellent....the shockmount is well constructed and durable
          i owned the ST51 from sterling audio and it was a GREAT microphone.....so when i decided to upgrade it was a no brainer to buy another sterling audio mic....this mic has a CRISP and CLEAN sound with EXCELLENT high end on vocals

          Like Singing in the Shower

          By Peter Peloghitis

          from Austin, TX

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          I was looking for a large diaphragm tube condenser microphone but the prices were more than I could afford, I wanted a new one rather than a new one due the 'tube' to make sure I had a warranty. I ran across several great reviews of the ST66 and the price was quite reasonable.at under $400 (including a nice quality mic stand).

          Musician's Friend quickly processed and shipped my order and I recieved it promptly via FedEx (free shipping). The mic comes in a box with all accessories included (phantom power unit with it's cables, and shockmount). The mic itself seems solid and well built. Everything worked and after a quick minute had it setup.

          I immediately fell in love with this mic. Normally, I would run my mic through some effects constantly tweeking them for the best sound. With this mic I found that a minimal bit of hardware compression and reverb was all I needed. The mic is a pleasure to sing through, it's like an instrument for singers like a guitar is to a guitarist. It really pulls the best qualities from your voice and give a pleasant fullness. It must be the tube that gives a natural compression for a gutsy sound when pushed somewhat at higher volume... sweet.

          I hope you get to check this mic out... I give it an A+, esp. for the price. Way to go Sterling Audio... Thank You.

          Can't beat this price!

          Good Vocal Mic

          By Danielle Resende

          from Carrollton, TX

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          I am male baritone country singer and bought this microphone solely for recording vocals. I first recorded using the preamp on the mackie mixer or on the steinberg audio interface. I couldn't seem to get the sound I was after. I felt the sound was kind of muddy and missed the subtleties of my voice. I actually preferred my sm57 using those same preamps. I then purchased a GAP Pre73 preamp and I have to say what a difference! The ST66 is now much better sounding with my voice making it sound more warm than muddy. I can hear the details in my voice a whole lot more. The sound of the sm57 improved also but it wasn't such a startling difference as the st66. I guess the bottom line is if you're going to buy this mic make sure you use a high quality preamp with it or you might be disappointed.

          Warm as Toast

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          I bought this mic blind out of the gate for the price for what it was. I was blown away at how great this mic is for vocals. Warms up any vocalist.As for intruments I've only used it on acoustic guitar and I thought it was decent. It's missing some of that top end jangle that you get from a standard condensor. However if you want to warm up your aoustic it works fine for that. I've been very pleased with this mic would buy another Sterling Audio mic.

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          This is by FAR the best Mic investment I ever made. I have NOTHING to say about this mic in a negative way. It is the best sounding mic you can ask for. Do not let the price fool you, it more than worth it. A whisper or a yell produces the exact same effects and it will serve you 2X back in tone, quality and ambient satisfaction. I use it for recording only, never took it out of the studio, So live recordings may prove to be different. But for a studio, this is one of the best values I seen yet.

          Forget about the RODE NTK!!

          Comments about Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone:

          I was so surprised when I used this mic how warm sounding it is. I was getting ready to buy a RODE NTK and knew and have used it but was told about the ST66 and was blown away. IF you're looking for a nice mic at a great price (which by the way I paid more for) you can't go wrong. It uses a Groove Tubes tube inside and is basically the same model as the Groove Tubes GT66 but much warmer.
