Sontronics SIGMA 2 Phantom-Powered Ribbon Microphone Review
The Sontronics SIGMA 2 Phantom-Powered Ribbon Microphone combines classic ribbon character with modern power and sensitivity. It uses a highly responsive ribbon element and requires 48V phantom power, giving you a stronger signal without losing that soft, warm ribbon sound. Its true figure 8 pickup pattern captures sound from the front and back while blocking noise from the sides, making it ideal for studio vocals, acoustic instruments, and detailed performances. Hand built in the UK, the SIGMA 2 offers low self noise, excellent clarity, and a timeless look that fits beautifully in any recording setup.
