The Sontronics STC-1 Silver is a highly versatile, small-diaphragm pencil condenser microphone, expertly designed to deliver breathtaking clarity and precision for acoustic instrument recording. Finished in a classic brushed silver, the STC-1 features Sontronics’ signature smooth high-end roll-off. This deliberate acoustic tailoring guarantees that your recordings remain exceptionally natural and unhyped, perfectly capturing the delicate transients and nuances of acoustic guitars, strings, woodwinds, and percussion without the harsh, fatiguing top-end frequently found in many small-diaphragm condensers in its class.
A defining feature of the Sontronics STC-1 Silver is its incredible modular flexibility, making it a powerful studio investment. Out of the box, the microphone is fitted with a tightly focused cardioid capsule that excels at direct spot-miking and isolating sources. However, this capsule head can be quickly and securely unscrewed and replaced with Sontronics' optional interchangeable OMNI (omnidirectional) or HYPER (hypercardioid) capsules. This brilliant design allows you to instantly adapt a single microphone body to any recording scenario—from capturing expansive orchestral room ambience to hyper-isolating a snare drum on a crowded stage.
Engineered to withstand the rigors of heavy studio sessions and live touring, the microphone features a solid brass chassis. To ensure you maintain absolute dynamic control over your signal at the source, the body houses two highly intuitive switches. A three-stage attenuation pad (0dB, -10dB, -20dB) allows the STC-1 to comfortably handle incredibly loud sound sources up to an impressive 137dB SPL, while a three-stage high-pass filter (Linear, 75Hz, 150Hz) effortlessly tames low-end stage rumble and proximity effect. The microphone is supplied in a premium velvet-lined wooden presentation box, complete with a sturdy mic clip and a high-density foam windshield.
