Step 1: Use the template (provided
as part of the packaging) to mark wall
for cut-out (far left). Position equally
between battens. Use this alternative
method (left) to mark battens prior to
wall covering.
Step 2: Ensure that 12in (300mm) of
each cable is present in the wall cut-
out.
Step 3: Fix back-box into cut-out.
Thread cables through correct holes
in back box: audio/comms cables
come in from the top; power from the
bottom (seeseparate sheet for power
wiring installation instructions).
Step 4: Tidy and clamp all cables. Fit
covers to power and audio boxes. Step 5: Carefully connect power and
audio between loudspeaker unit and
back box. An IEC connector is used
for power; DSUB
for digital audio. Be sure to install the
digital cable with the choke on the
end next to the speaker.
Step 6: Neatly position power
and comm cables and push the
loudspeaker unit all the way in so
that it locates on the pegs in the
back-box. Secure using the six M5
x 12 button-head socket screws
supplied, Meridian part number
H61513.
See separate sheet for important safety
instructions! Illustrations are not all to the
same scale.
Step 7: Secure frame and fit grille.
Grille can be carefully removed using the
extraction tools supplied.
