The Sontronics Sigma 2 is a professional large-diaphragm condenser microphone designed for studio recording applications, offering a versatile solution for vocalists, instrumentalists, and podcasters. This successor model features a 25.4 mm (1 inch) gold-sputtered diaphragm with a cardioid polar pattern, providing focused sound capture while minimizing background noise. With a frequency response of 20 Hz to 20 kHz and a maximum sound pressure level of 140 dB, the microphone handles both subtle acoustic performances and powerful vocal delivery. The Sigma 2 includes a three-position high-pass filter (flat, 80 Hz, 160 Hz) and a three-position pad (-10 dB, -20 dB, flat) for flexible signal control. Constructed with a durable all-metal body measuring 200 mm in height and 60 mm in diameter, the microphone weighs 650 g and includes a shock mount and protective carrying case. The microphone operates with standard 48V phantom power and features a low self-noise of 12 dB(A), making it suitable for professional recording environments where clarity and reliability are essential. The included shock mount effectively reduces handling noise and mechanical vibrations, while the cardioid pattern provides natural off-axis rejection for clean recordings in treated spaces. The microphone's extended frequency response captures detailed highs and full lows, with the high-pass filters helping to control proximity effect and room rumble. The adjustable pad settings prevent distortion when recording loud sound sources, ensuring optimal signal levels for various applications. The robust construction and included accessories make the Sigma 2 a practical choice for home studios, project studios, and professional recording facilities seeking a versatile condenser microphone for vocal recording, acoustic instruments, and spoken word applications.
