GENERAL
The A89SM shock mount reduces mechanical noise
transmission by more than 20 dB. Designed for the Shure
SM89 shotgun microphone, it also fits any 3/4” diameter mi-
crophone.
FEATURES
S Three integrated thread sizes allow you to attach the
mount to stands or booms with 3/8–16, 5/8–27, or
5/16–18 threads.
S A cable securing mechanism prevents the transmis-
sion of mechanical noise through the cable and con-
nector.
S Locking, pivoting design provides maximum aiming
capabilities.
MOUNTING
Attach the A89SM to a stand or boom. If necessary, install
the 5/16” adapter socket, or use the 3/8” or 5/8” threads in
the reversible swivel.
To reverse the orientation of the swivel adapter, remove
the swivel by unscrewing the swivel lock nut, then reinstall
it with the desired orientation.
When not using the 5/16” socket, store it by screwing it into
the threaded hole on the side of the A98SM, next to the cable
loop slot.
