Product Overview

The Pinnacle of Smooth Analog Character

The Sontronics SIGMA 2 represents a massive leap forward in ribbon microphone design. While traditional passive ribbon microphones are notorious for low output levels, impedance mismatches, and fragile handling, the SIGMA 2 utilizes phantom-powered active circuitry. Hand-built and individually tuned in the United Kingdom, this microphone delivers a robust, reliable output signal that pairs beautifully with any standard studio audio interface or mixer preamp, all while preserving the highly coveted, velvet-smooth high frequencies that ribbon elements are legendary for.

Product Description

Premium Active Electronics and Custom British Transformer:

At the heart of the SIGMA 2 is an ultra-thin, hand-tensioned ribbon motor element working in perfect harmony with Sontronics’ proprietary active preamp circuitry. By incorporating 48V phantom power into the design, the microphone maintains a highly consistent impedance and a significantly higher output sensitivity than vintage ribbons. This means you get dead-silent tracking with absolutely zero electronic hiss. The circuit is tied together by a bespoke, custom-wound British transformer, which adds an extra layer of harmonic complexity, weight, and subtle analog saturation to your tracks.

True Figure-of-Eight Polar Pattern and Natural Voicing:

The SIGMA 2 features a highly accurate, symmetrical Figure-of-Eight polar pattern. This design allows the microphone to capture the direct instrument tone perfectly from the front, while simultaneously catching natural, three-dimensional room reflections from the rear with extreme phase consistency. The frequency response is intentionally crafted to mimic human hearing, offering a completely flat, non-hyped mid-range, a full-bodied low-end bloom, and a gentle high-frequency roll-off that tames the "fizz" and harshness often found in modern condenser microphones.

Unique Shockmounted Frame and High-Durability Build:

Ribbon microphones are historically fragile, but the SIGMA 2 is built to endure the rigorous demands of professional commercial studios and live touring stages. The microphone body features an integrated internal shock-absorption system alongside a unique, heavy-duty cylindrical outer frame that isolates the ribbon element from structural floor vibrations. Its rugged all-metal construction is designed to protect the internal motor while looking exceptionally elegant on camera. For maximum protection, it comes beautifully packed in a luxury velvet-lined wooden presentation case inside a tough aluminum flight box.

Key Features
