Bidirectional Active Ribbon Microphone
Description
The Sigma is a phantom-powered ribbon microphone.
It ships in a padded ABS (plastic) carrying case with the microphone’s visually-distinctive shockmount.
SoundOnSound
A spoken-word vocal test showed the tonality to be extremely warm and silky. Those with indistinct voices might find it a disadvantage, but where there is harshness that needs to be polished over, this mic is definitely up for it. There seems to be a subtle tonal difference between the front and rear of the microphone, but on voice it is barely noticeable and both sides pour on the warmth like double cream.

The mic was released in 2006.
