reposition the flange and loudspeaker to the
correct position shown in Figure 16.
Next place the grille on the mounting
flange. The grille is held in place by magnets.
Choosing and installing
the loudspeaker cables
The RAM1 amplifier unit has separate
power amplifiers for the tweeter and woofer.
Accordingly, there are two pairs of binding
posts, white (-) and red (+) for the tweeter
and black (-) and grey (+) for the woofer.
Be sure to maintain correct polarity when
connecting the loudspeaker cables and
be extra careful not to mix the tweeter and
woofer cables
Use a good quality 4-conductor cable and
make the cable runs as short as possible.
See Table 1 for recommended cable gauges.
The binding posts accept a cable up to 6
mm
2
(9 gauge).
If you are installing the AIW26B system
to an existing wall, examine the walls
thoroughly for the shortest and least
obstructed cable route. Be careful to avoid
cutting or drilling into electrical wires,
ventilation or water pipes. These are often
visible in the attic, basement or crawl space
below the floor. It is a good idea to route the
loudspeaker cables away from electric or
video cables, which might induce hum into
the loudspeaker system.
Connecting the RAM1
amplifier
The RAM1 amplifier is designed to be
connected to a line level output of a
preamplifier, Surround Sound processor
or other low level source. NOTE! Never
connect the RAM1 to a loudspeaker level
output of a power amplifier! Before making
the connections, check that the voltage
selector on the amplifier’s back panel is set
to the correct voltage and the power on all
components is turned off.
Start by connecting the loudspeaker
cables to the amplifier’s binding posts
(see Fig. 22). Check that the amplifier’s
serial number matches that of the AIW26B
loudspeaker enclosure which it will power.
The number can be found on a sticker on
the loudspeaker’s reflex port and on the
amplifier’s top cover. If the loudspeakers
are not yet installed, make a note of
which amplifier is connected to each
channel. Check the cable polarity and use
the provided cable binding post tool to
tighten the binding posts. Be careful not to
overtighten the binding posts as they may
be damaged.
The RAM1 has two parallel 10 kOhm
input connectors: a balanced XLR and
an unbalanced RCA. For longer cable
connection lengths (>10m or >30ft) a
balanced line connection is recommended
as it offers better immunity to external
interference. The RCA connection
method usually works as well for shorter
connection lengths in less electrically noisy
environments. Do not use both inputs at the
same time. Consult your Genelec dealer for
the choice of signal cables.
The RAM1 has a provision for remote
controlled switching between “ON” and
“STANDBY” modes (not available in units
sold in the EU). The “REMOTE CONTROL”
connector block has two connector pairs:
1-2 for a 12 V DC trigger remote control
and 3-4 for an external switch or relay type
(contact closure) remote control (see Table
2). Do not connect two remote controls to
the amplifier at the same time.
Space requirement for the
RAM1 amplifier
The dual 120 W power amplifiers of a RAM1
unit generate a large amount of heat when
used at full power. To avoid overheating,
ensure that there is good airflow around
the amplifier and no external heat sources
close to it. We recommend installing the
RAM1 into a well ventilated equipment rack
using its dedicated RM1 rack mount kit.
If the RAM1 amplifier is placed in a
cabinet, on a shelf or into an equipment
rack without its dedicated RM1 rack mount
kit, there must be at least 100 mm (4 in)
of free space behind, 150 mm (6 in) above
and 50 mm (2 in) on both sides of the
amplifier to ensure adequate cooling (see
figure 23).
Mounting the RAM1 amplifier
to an equipment rack
We recommend that you use the Genelec
RM1 rack mount kit when installing the
RAM1 amplifier in an equipment rack. Make

have no Autostart and Remote Control functions.
