Genelec AOW312B Active On-Wall Loudspeaker

System

The Genelec AOW312B is a three-way active

loudspeaker system designed for medium

sized, high quality home theater applications.

This system excels as side or rear channels

when mounted on-wall. It also offers mini-

mum 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.

Designed as an active loudspeaker system,

each AOW312B system contains an individu-

ally matched RAM4 amplifier unit with multi-

ple power amplifiers, active crossover filters

and protection circuitry.

The unique Directivity Control Waveguide™

(DCW™) technology developed by Genelec

provides extremely stable and accurate imag-

ing and frequency balance even in difficult

acoustic environments. Furthermore, versa-

tile and precise crossover controls allow for

accurate matching of the loudspeakers sys-

tems to different room acoustic conditions.

The AOW312B is fixed to the wall via

unique mounting brackets which isolate and

suspend the enclosure vertically. The brack-

ets also allow the enclosure 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, thus eliminating the effects of

component tolerances and ensuring consist-

ent 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”) mid-

range cone and 25 mm (1”) HF driver are

loaded into the proprietary Directivity Control

Waveguide™.

The RAM4 amplifier unit contains an active

crossover, the ideal method for dividing an

input signal between the driver units, allow-

ing the overall response of the system to

be optimized to an extent impossible with a

passive system. Variable input sensitivity as

well as a balanced XLR line level input con-

nector 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

system incorporates special circuitry for driver

overload and amplifier thermal protection, as

well as an “Autostart” function for automatic

switching between “Standby” and “On” power

modes. A connector for 12 V trigger or exter-

nal switch or relay type remote control facili-

tates central power mode switching.

The 3U RAM4 remote amplifier module

is ready to be installed into a 19” equip-

ment rack. Neutrik Speakon connectors are

included to facilitate wiring and system con-

nection. Signal cables are not provided with

the system. See section "Connections" below

for selecting signal cables.

Installation

Once unpacked, place the lo udspeaker

enclosure upright in its required position,

taking note of the line of the acoustical axis

(see Figure 2). Attach the mounting brackets
