Strip 8mm (1/4 inch) of shielding from the end of the speaker cables in preparation
for connection to the spring terminals on the rear of speaker. Check that the
clamping arms are aligned as shown prior to insertion in the wall.
Connect the speaker cable observing the correct wiring polarity. The positive
terminal (marked + and coloured red) should receive the positive cable (usually
marked with a repeated stamped name, line or raised rib) and the negative
terminal (marked – and coloured black) the negative cable.
Insert the baffle into pre-prepared hole in the wall, ensuring that the speaker wire
is located securely away from the driver – contact with the driver cone will cause
annoying buzzes.
Each of the six clamp screws can now be tightened (clockwise). Starting at one
corner then moving to the opposite corner, tightening sufficiently to check for
visual orientation, before proceeding to tighten the other two corners. Finish off
by tightening the two middle clamps.
WARNING
Do not over tighten the screws – this is unnecessary to achieve a strong acoustic
seal to the wall and risks damaging the wall surface
Repeat the installation procedure for the other loudspeakers and complete the
connection process to the amplifier. Once again ensure that correct cable polarity
is observed.
Switch on the amplifier with the volume control at its lowest setting. Select a signal
source and slowly turn up the volume to a low level. Check that bass and treble
information comes from both speakers – if not, switch off the amplifier and recheck
the connections.
Carefully check the area surrounding the installation and ensure that there are
no buzzes or rattles that could potentially impair enjoyment of the system – If
there are then locate and silence the causes using cable ties or suitable packing
material.
Optimum performance will be assisted by the use of silicone sealant, or similar
material, to seal gaps, for instance, between the studs and the wallboard material.
This cavity sealing will help to create a near airtight seal.
GRILLE FITTING AND REMOVAL
The grille should be carefully fitted to the front baffle aperture, by lining up the
edges of the grille carefully with the baffle. To avoid indentation damage do not
press the centre of the grille; apply even pressure to the corner as it is pressed
firmly into position.
To remove the grille loop an opened paper clip, or similar length of firm wire,
through two holes near a corner and pull gently. The grille is intended to be a
tight fit, so insert the wire at each corner in turn pulling carefully to avoid distortion
of the mesh.
