Genelec AOW312 Active On-Wall Loudspeaker

System

The Genelec AOW312 is a three-way active
loudspeaker designed for medium sized,
high quality home theater applications. This
system excels as side or rear channels when
mounted on-wall. It also offers minimum
intrusion into designed spaces while pro­viding high sound pressure levels required
when employing Genelec’s large three-way
systems for left, center, and right positions
and HTS6 series subwoofer in rooms greater
than 260 m3 / 9000 cu. ft.

De signe d a s an active l oudsp eaker
system, it contains multiple driver and power
amplifiers, active crossover filters and protec­tion circuitry.

The unique Directivity Control Waveguide™
(DCW™) technology developed by Genelec
provides extremely stable and accurate imag­ing and frequency balance even in difficult
acoustic environments. Furthermore, versa­tile and precise crossover controls allow for
accurate matching of the loudspeakers sys­tems to different room acoustic conditions.

The AOW312 is fixed to the wall via unique
mounting brackets which isolate and sus­pend the cabinet vertically. The brackets also
allow the cabinets to be mounted with a ±15
degree angle offset to the wall to facilitate
energy focus at desired listening locations.

All electronics are factory calibrated as

a single unit eliminating the effects of com­ponent tolerances and ensuring consistent
quality and long term reliability.

Low frequencies are reproduced by a 305
mm (12”) bass driver with a low frequency
extension to 35 Hz. The 130 mm (5”) mid­range cone and 25 mm (1”) HF driver are
loaded into the proprietary Directivity Con­trol Waveguide as found on the HT312 and
HT315 models.

The ampl ifier unit co ntains an a ctive
crossover, the ideal method for dividing an
input signal between the driver units, allow­ing the overall response of the system to be
optimized to an extent impossible with a pas­sive system. Variable input sensitivity as well
as XLR line level input connectors provide
easy connection and accurate level match­ing to the preamplifier or surround decoder.
The bass, midrange and treble amplifiers of
the AOW312 produce 180 W for the low fre­quency driver and 120 W each for the mid­range and HF drivers.

The amplifiers are designed to operate at
very low THD and IM distortion values and
are capable of driving the AOW312 to peak
output levels in excess of 124 dB SPL at 2 m
with music material.

Like all Genelec HT models, the AOW312
incorporates special circuitry for driver over­load and amplifier ther mal protection, as
well as an “Autostart” function for automatic

switching between “Standby” and “On” power
modes. A 12 V trigger or external switch or
relay type remote control also provides power
mode switching.

The 7U remote amplifier modules are sup­plied with 19” rack-mount metalwork and
Neutrik Speakon connectors are provided
to facilitate wiring and system connection at
customer facilities.

Installation

Once unpacked, place the loudspeaker in
its required listening position, taking note of
the line of the acoustical axis (see Figure 1).
Attach the mounting brackets to the wall with
suitable screws for carrying the loudspeak­er's weight of 43 kgs (95 lbs). The maximum
vertical tilt angle for the loudspeaker cabinet
is ±5 degrees.

The mounting brackets are pre-drilled for
cabinet alignment angles of -15°, 0° and
+15°. If necessary, you can drill new holes to
the brackets for exact loudspeaker alignment.
The rubber isolators provided must be placed
between the brackets and loudspeaker cabi­net. See Figures 3 and 4 for details.

It is recommended that the surroundings
of the loudspeaker are covered with about 10
cms (4") of rockwool or similar damping mate­rial. If the loudspeaker is covered with a cloth,
it must be acoustically transparent and a free
space of at least 2 cm (3/4") left between the
