Permanent Installation
Mount the microphone using one of the following methods.
Shock Mount
1. Drill a 44mm(1-3/4 in.) diameter hole in
desired mounting surface.
2. Mark and drill starter holes for screws,
using shock mount as a template.
3. Secure shock mount to mounting surface
with screws.
4. Thread the supplied adapter onto the
MX400SE microphphone before inserting
it into the shock mount.
Specifications
Flange
1. Drill a 22 mm (7/8 in.) diameter hole in the
desired location.
2. Trace and drill three starter holes for the
supplied screws using the flange as a template.
3. Insert the preamplifier through the mounting
flange.
4. Slip the mounting flange retaining ring over the
bottom of the preamplifier and slide it up until it
is flush to the bottom of the flange. Then press
the ring firmly into place.
5. Secure the flange to the mounting surface with
three screws.
