Genelec AOW312B

Active On-Wall Loudspeaker

Being a three-way active loudspeaker

designed for medium sized, high quality

home theater applications, the AOW312B

excels as side or rear channels when

mounted on-wall with Genelec’s large

three-way systems for left, center, and

right positions and HTS6 series subwoofer

3

in rooms greater than 260 m

However, the AOW312B is also capable of

a commanding performance in the L-C-R

main loudspeaker array of smaller rooms,

where its minimal intrusion into the room

saves space and gives additional freedom

for the front wall design.

Designed as an active loudspeaker

system, the AOW312B contains multiple

driver and power amplifiers, active cross-

over filters and protection circuitry.

The RAM4 3 U remote amplifier module

(9000 cu. ft.).

is supplied with 19” rack-mount metalwork

and Neutrik Speakon connectors are

provided to facilitate wiring and system

connection at customer facilities. Every

amplifier is calibrated for optimal per-

formance with the loudspeaker unit it is

shipped with. This eliminates the effects

of component tolerances and ensures

consistent quality and long term reliability.

The unique Directivity Control Wave-

guide™ (DCW™) technology developed

by Genelec provides extremely stable and

accurate imaging and frequency balance

even in difficult acoustic environments.

Furthermore, versatile and precise cross-

over controls allow for accurate matching

of the loudspeakers systems to different

room acoustic conditions.

The AOW312B is fixed to the wall by

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.

Low frequencies are reproduced by a

305 mm (12”) bass driver with a low fre-

quency extension down 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 HT312B and HT315B models.

The RAM4 amplifier unit contains an

active 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. Vari-

able 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 RAM4 produce 180 W for the low

frequency driver and 120 W each for the

mid-range and HF drivers.

The amplifiers are designed to operate

at very low THD and IM distortion values

and are capable of driving the AOW312B

to peak output levels in excess of 124 dB

SPL at 2 m with music material.

Like all Genelec HT models, the

AOW312B incorporates special circuitry for

driver overload and amplifier thermal pro-

tection, 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.

Where high quality and high output are

essential the AOW312B will bring a new

level of delivery and application to the

custom home theater as well as the com-

mercial installer.
