Sontronics' SIGMA phantom-powered ribbon microphone is one of our most popular products thanks to its incredible performance and value for money.
Ribbon mics are renowned for their smooth, uncoloured audio characteristics but most have a transformer-based output, which makes it difficult to achieve consistency when using different preamps. SIGMA, however, is phantom-powered and operates just like any other Sontronics condenser mic, allowing you to plug and play with practically any preamp.
