The Sontronics Sigma 2's circuitry incorporates RFI (radio frequency interference) filters that ensure that Sigma 2's signal remains interference-free and makes the microphone even more suited to live use than before. The only ribbon mics in the world to boast this feature!

Sigma 2 has extremely high sensitivity and incredibly low self-noisemaking it ideal for capturing vocals, speech, solo woodwind, stringed instruments and guitar amps, presenting an exceptionally detailed, accurate, natural sound.

Utilising the same super-sensitive ribbon motor as the original, SIGMA 2 offers stunning clarity and definition in the top end but now also boasts richer mid and low tones.

A pair of Sigma 2 (either spaced separately or in X-Y configuration) can be used for extremely effective overhead and room miking, upright or grand piano, string quartet and other ensembles. 

Sigma 2 as with any ribbon microphone, should be used with care as its ribbon element is very delicate. However, with sensible placement and careful handling, Sigma 2 will give you incredible results time and time again. 

This microphone is supplied with its unique-style shockmount in a sturdy, foam-padded ABS flightcase, which will keep your mic safely stored between sessions or when transported from one venue to another.
