2. Locate the center of the mounting location and mark it.
Allow
enough clearance to accommodate the AT8474 mount on
the desired surface and make certain there are no physical
obstructions below the desired location.
3. Locate the three mounting screw holes and mark them.
4. Using a 1" hole saw, drill the through-hole for the microphone body.
(Note: although a 1" drill bit will work, a hole saw provides
for a cleaner hole and is less likely to damage the table surface.)
5. Using a
1
/
16
" (1.5 mm) drill bit, drill three pilot holes for the mounting
screws. (If mounting below the table surface, be certain
NOT
to drill
pilot holes through the table.)
6. Place the AT8474 mount over the hole and partially tighten the
three screws. Then place the microphone in the AT8474 so that
the microphone's power module (base) extends through the
AT8474 mount into the hole. Tighten all three screws evenly.
For maximum security, the screws should be tight enough to
ensure that the microphone is held securely in place and can
not be removed without loosening the screws.
7. If mounting the AT8474 mount below the surface of the table,
slide the rubber trim ring over the microphone (above the table
surface) and seat it between the microphone and the sides of
the hole for a finished appearance. (If mounting the AT8474
above the surface of the table, you may also choose to use the
trim ring beneath the surface of the table, for added attenuation
of noise, shock and vibration.)
8. After installing the microphone, assure maximum shock mount
effectiveness by providing some slack in the connecting cable.
The cable can be secured to the table with a standard wire clip
or cable tie (not included).
