Classic Ribbon Performance

The Sontronics SIGMA 2 is a phantom-powered ribbon microphone engineered for rich, natural sound with modern reliability. Featuring a true figure-of-eight polar pattern, it captures audio equally from the front and rear while rejecting unwanted side noise. With a wide frequency response of 20Hz–15kHz, high sensitivity, and ultra-low self-noise, SIGMA 2 delivers smooth, warm recordings full of detail and character. Its ribbon design excels at reproducing vocals, strings, brass, and woodwind instruments with remarkable realism, making it a trusted choice for professional studio recording and critical listening environments.

Warm Vintage Tone

Designed to preserve the classic ribbon microphone sound, SIGMA 2 offers an intimate, smooth, and naturally balanced tonal character. It gently tames harsh high frequencies while maintaining clarity and depth, resulting in recordings that feel musical and organic. Whether capturing vocals, acoustic instruments, or orchestral performances, the microphone responds beautifully to subtle dynamics. The phantom-powered ribbon element ensures a strong output signal without sacrificing tonal warmth, allowing effortless plug-and-play use with audio interfaces, preamps, and mixers while maintaining the timeless sonic charm ribbon microphones are known for.

Precision Figure Eight

The true figure-of-eight polar pattern makes SIGMA 2 exceptionally versatile in studio environments. By capturing sound from both the front and rear while rejecting side noise, it is ideal for stereo techniques, room recordings, and creative mic placements. This design allows engineers to achieve natural spatial depth and accurate imaging, especially when used in matched pairs. With a high maximum SPL of 125dB, SIGMA 2 can handle louder sources when used carefully, delivering controlled, distortion-free recordings across a wide range of professional applications.
