Genelec AIC25 Active In-Ceiling Loudspeaker
The Genelec AIC25 Active In-Ceiling loud-
speaker system consists of a two-way
loudspeaker enclosure and a matched
remote amplifier module, RAM2. It has been
designed to the same rigorous standards
as Genelec’s high-performance HT series
active Home Theater loudspeakers. No other
In-Ceiling loudspeaker in this size class can
match the low distortion, neutrality and high
sound pressure capability of Genelec AIC25.

Installation
Genelec recommends that you use the serv-
ices of an authorized installation specialist or
other competent and experienced installa-
tion company for the installation of the AIC25
system. Ask your local Genelec dealer for
recommended installation companies in your
region.
Matching loudspeakers and
amplifiers
Each AIC25 loudspeaker has been factory
calibrated for optimum performance with the
RAM2 amplifier it is shipped with. Never mix
these matched amplifier-loudspeaker sys-
tems in the installation process. The matching
units are marked with the same ID number.
Cabling
The RAM2 amplifier unit has separate power
amplifiers for the tweeter and woofer. Accord-
ingly, a 4-conductor cable needs to be run
between the amplifier and the loudspeaker
enclosure. Two cable connectors are sup-
plied with the loudspeaker system, a six-pole
connector to fit the connector on the amplifier
and a four-pole connector to fit the respective
input on the top of the loudspeaker enclo-
sure.
Attach the cables to the green connectors
provided with the kit. Be sure to maintain cor-
rect polarity when connecting the cables and
be extra careful not to mix the tweeter and
woofer cables. The correct pin sequences
are marked on the amplifier and loudspeaker
enclosure. Starting from the top, the first two
poles on the amplifier connector are for the 12
V remote control voltage, pole 3 for tweeter -,
pole 4 for t, pole 5 for woofer - and
pole 6 for . Respectively, the pole
sequence on the loudspeaker connector is
1 tweeter -, 2 t, 3 woofer - and 4
. Secure the cable to the strain relief
tie next to the loudspeaker connector.
Use a good quality 4-conductor cable and
make the cable runs as short as possible.
See Table 1 for recommended cable gauges.
The connectors accept a cable up to 6 mm
2
(9 gauge) thick.
If you are installing the AIC25 enclosure
to an existing construction, examine the
ceiling thoroughly for the shortest and least
obstructed cable route. Be careful to avoid
cutting or drilling into electrical wires, venti-
lation or water pipes. All of this is of course
much easier when the installation takes place
in an unfinished building where the ceiling
structure is still open. In both cases it is a
good idea to route the loudspeaker cables
away from electric, video or phone cables,
which might induce hum into the loudspeaker
system.
