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 5: Tidy and clamp all cables. Fit
covers to power and audio boxes.
Step 6: Carefully connect power and
audio between loudspeaker unit and
back box. An IEC connector is used
for power; XLR for analogue; DSUB
for digital audio. Be sure to install the
digital cable with the choke on the
end next to the speaker.
See separate sheet for important safety
instructions! Illustrations are not all to the
same scale.
