The Thronmax S3 Zoom is a boom arm designed for Thronmax microphones. It offers a 360° rotatable boom, with a rotary knob that allows you to shift the microphone and make angle adjustments with ease. Dual suspension springs on each section of the boom arm help isolate your mic from structurally born vibrations, so you won't hear rumble and shaking noises. Also, the springs help secure your mic in place.
