Proceed as follows:
1. Remove the upper of the two mounting brackets
from the rear of the loudspeaker by undoing the
M8 x 16 hex-head screws securing it (see Fig.20).
The four "keyhole"-shaped holes in the rear plate of
the bracket are used to fix the brackets to the wall. Use
of the wall plugs and hexagon head screws supplied
is recommended. If using other types, ensure that the
"across-flats" head size does not exceed 15 mm (0.6").
2. Using the bracket removed in Step 1, mark the wall
for the wall plugs. Refer also to the Mechanical Details
drawing in the datasheet supplied with the loudspeaker.
Check the dimensions given from the reference datum
to each pair of mounting holes, and allow for the offset
of the acoustic centre from the reference to ensure that
the acoustic centre will be at the height defined in the
acoustic design specification. Reference to Fig.17 may
also be helpful. Drill the holes (Ø 10 mm).
3. Insert the plugs and screws into the holes. Tighten the
screws with a spanner, but stop with a few mm of screw
shaft visible between the head and the wall.
4. Check that it is possible to slide a bracket over the
heads.
5. Check that the chosen mounting points will position
the column in the correct vertical angle specified by the
acoustic design (which is usually exactly perpendicular
to the listening area). Use spacers on one or more of the
brackets if necessary.

6. Next, re-attach the bracket to the rear of the Intellivox
enclosure using the screws and washers removed in
Step 1. Ensure that both brackets are oriented correctly,
with the keyhole slots upwards. Tighten with a spanner,
or with a hex socket using the 16 mm dia. holes for
access for the socket driveshaft.
7. Ensure that all connections to the unit have been made
before the unit is lifted into place.
The unit should not be powered during
installation. The connector bay contains live
parts and should only be opened if the
mains power has been disconnected.
8. Lift the Intellivox and slide the brackets over the heads
of the hex-head screws protruding from the wall.
9. Firmly fasten the screws securing the brackets to the
wall. Re-check the verticality (or other angle if specified)
with a spirit level or similar levelling device.
