309A
Microphone
Suspension/Shock Mount
General Description:
The Electro-Voice 309A suspension shock mount
was designed specifically for use with the RE20,
RE27N/D, and RE320 dynamic microphones. It provides
near-perfect shock isolation for those already internally
shock mounted microphones. 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, RE27N/D, or RE320 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.
Four (4) molded neoprene shock cords suspend and
support the microphone within an aluminum and steel
frame-work to effectively isolate it from mechanical shock
and vibration.
