The SH100 from AKG is a Spider Suspension for Perception microphones. The SH100 suspends the microphone in an elastic mount, giving it isolation from the stand itself, meaning it protects your recordings from vibration, rumbles and noise. The mount works with AKG's Perception 200, 220 and 400 but will also fit similar sized microphones, such as the AKG Perception 120.
The main features of the SH100 include:
It has the incovinient of not being included with the AKG Perception 120, however, its worth the money since it fits perfect to the microfone. Very resistant, and makes the microphone be very steady, which is exactly what you need.
