MOUNTING PROCEDURE

The general procedure for mounting the Intellivox ADC
Models V90 or H90 using the standard brackets is described
below. It is assumed that cabling for connection to the
100 V/70 V line system has been run to the loudspeaker
location.
Proceed as follows:
1. 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 11.5
mm (0.45").
2. Mark and drill the holes (8 mm) for the wall plugs. For the
V90 use the two holes with the slots running vertically as
reference. For H-90 use the slotted hole in the centre of
the bracket as reference.
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 (in the case of the Model V90, this
is usually exactly perpendicular to the listening area).
Use spacers on one or both brackets if necessary.
6. Attach the brackets to the rear of the loudspeaker
using the M5 x 12 pan-head screws and shakeproof
washers supplied. The 10 mm diameter holes allow
screwdriver access to the screw heads.

7. Remove the front grill from the loudspeaker by gently
lifting it at the locations of the 'snap-on' fittings which
hold it in place. Remove the protective foam. Unscrew
the four self-tapping screws securing the connector
compartment cover and remove the cover.

8. Lift the loudspeaker and slide the brackets over the
heads of the hex-head screws protruding from the wall,
and at the same time feed the speaker cable through
the cable entry gland at the rear and into the connector
compartment so that it is free and accessible from the
front. Tighten the rear gland, leaving sufficient free
cable to connect to the terminal block.
Ensure that the gland fits tightly around the
cable jacket. The enclosure protection, as
well as the LF SPL response, will deteriorate in case of
a leaky enclosure.
9. Firmly fasten the screws securing the brackets to the
wall with the spanner. Re-check the verticality (or other
angle if specified) with a spirit level or similar levelling
device.
10. The loudspeaker connections should now be made –
