## Description

The SIGMA is a fusion of modern technology and vintage style. The SIGMA s speciality is to recreate the silky, rich tones that we heard from those old recordings, but without the pops and crackles . Punchy low and mid frequency responses, combined with an ultra-smooth high frequency roll-off, produce a very natural image, almost making the instrument or vocal sound like it is in the room with you. The SIGMA is phantom powered and its output is actively balanced which means, unlike most transformer-based ribbon microphones, it does not suffer from impedance mismatching problems and low output sensitivity. In fact, it is as easy to use as any other Sontronics condenser microphone just plug it into your preamp and play! The circuit design delivers some of the lowest self-noise figures of any ribbon microphone on the market and the aluminium ribbon element itself is less than 2 microns thick, all of which goes to make a very accurate and responsive microphone. Apart from its good looks, the unique shockmount system is extremely effective and allows the microphone to be placed close to the source with complete isolation from noise transmitted through the mic stand. The applications for SIGMA are truly varied, but Broadcast, Vocal, Acoustic and Orchestral Instruments and Drums and Percussion are a few options you should consider.
