The SMH-2 is a shock-mount microphone holder with a standard size shoe mount for camera-top mounting. Two plastic clips firmly hold on to the microphone's case while two rubber spacers isolate and protect the microphone from handling noise and vibration. The SMH-2 works best with shotgun microphones with a diameter of 21 to 22 mm. Compatible Azden models include SGM-1X, SGM-250, SGM-250P, SGM-PII and SGM-PDII.
