Painting the Loudspeakers
The visible parts of the loudspeaker (grill and its surround) can be spray painted to match the wall
colour and interior decorations.
Environmental Requirements for the RAM1 and RAM2 Amplifier modules
The dual power amplifiers of the amplifiers generate some heat when used at full power. To avoid
overheating, ensure that there is good airflow around the amplifier and no other heat sources close to
it. We recommend installing the amplifiers into a well ventilated equipment rack using their dedicated
RM1 and RM2 rack mount kits. Sufficient cooling for the amplifier must be arranged at all times. As
a general rule, the ambient temperature around the amplifier must not exceed 35 degrees Celsius
(95°F). See the Operating Manuals of these systems for more detailed information.
Connecting the Amplifier
The RAM1 and RAM2 amplifiers are designed to be connected to a line level output of a
preamplifier, surround sound processor or other low level source. The amplifiers have a balanced
XLR input and an unbalanced RCA input. If cable connection lengths are greater than >10 m or
>30 ft a balanced line connection is recommended as it offers better immunity to external interfer-
ence. However, the more common RCA connection method is also available for short connection
lengths in less electrically noisy environments. Do not use both RCA and XLR inputs at the same
time.
3.8.2 Installing the AIW26 Loudspeaker Enclosure
Use the cardboard wall cut-out template that also shows the loudspeaker drivers to find the best location for
the AIW26. The loudspeaker enclosure requires a minimum of 88 millimeters (3
sheetrock. The mounting brackets need a clearance inside the wall of at least 125 millimeters (5") above the
top edge of the hole and 65 mm (2
than the hole and requires about 30 millimeters (1
Lift the AIW26 into the hole top end
(cable binding posts) first and push
the lower end of the loudspeaker
onto the edge of the hole. Push both
mounting brackets fully up and hold
them there as you push the lower
half of the loudspeaker into the wall.
When the loudspeaker is in the cor-
rect position, pull the mounting brack-
ets down. The grill cover holds onto
the loudspeaker's frame with mag-
nets. All this takes about one minute
per enclosure once the hole is cut in
the wall!
3.8.3 Installing the AIW25 and AIC25 Loudspeaker Enclosures
Use the cardboard wall cut-out template that also shows the loudspeaker drivers to find the best location
for the loudspeaker. Examine the wall or ceiling structure carefully to find a clearly unobstructed location
for the loudspeaker. The loudspeaker enclosure requires a minimum of 98 millimeters (3
or 160 millimeters (6
note that the enclosure flange is wider and taller than the hole and requires about 20 millimeters (3/4") of
smooth wall surface around all sides of the hole. When you have found a good location, check that the
template is level and trace the hole onto the sheetrock with a pencil along the outline of the template and
make the cut along the marked lines.
