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

One of the features of Sterling Audio's large capsules is the exclusive Disk Resonator™ system. With it, they have been able to compensate for the 14kHz frequency roll-off that is inherent in large diaphragm mics. This deficiency translates to a lack of sparkle from high-frequency sound sources.

Other manufacturers have typically solved this problem with corrective EQ circuits after the capsule; “boosting” the high frequency which unfortunately results in increased noise and other negative sonic artifacts from this band aid circuit approach.

Disk Resonator™ Technology incorporates a gold-plated brass “umbrella” that protrudes from the center of the diaphragm in Sterling Audio’s ST55 and ST66 mics. 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 a “perfect storm” of audio reproduction: optimal sensitivity, full frequency response, and a low signal-to-noise ratio.

Another piece of audio wizardly 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 Dupont, has produced a highly resilient Mylar that measures a mere 3 microns. This allows the ST55 and ST66 to deliver a degree of sensitivity unparalleled in the industry.

The ST66 uses triode wiring on specially selected miniature 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.

These and many more audio innovations make Sterling Audio a stand out in today’s cutting-edge recording gear marketplace.
