Technical Specifications:
The Electro-Voice 309A suspension shock mount was
designed specifically for use with the RE20 and RE27N/D
dynamic microphones. It provides near-perfect shock isolation
for the already internally shock mounted RE20 or RE27N/D.
For most applications, the Model 309A may be attached
directly to the recording boom or to a floor stand. A stand
adapter with 5/8" -27 thread is provided.
The 309A mount design allows quick installation of the RE20
or RE27N/D microphone without tools. A double safety factor
is provided to ensure that the microphone will remain attached
to the shock mount under any conditions. First a “bayonet”
locking action assures that the microphone will not fall out of
the shock mount under its own weight. Additionally, a set
screw (wing type) can be tightened to lock the microphone in
place after it has been properly positioned.
