Genelec AOW312B Active On-Wall Loudspeaker
System
The Genelec AOW312B is a
Designed as an active loudspeaker system, each AOW312B system contains an individually matched RAM4 amplifier unit with multiple 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 AOW312B is fixed to the wall via unique mounting brackets which isolate and
suspend the enclosure vertically. The brackets 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 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”) 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
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 external switch or relay type remote control facilitates central power mode switching.
The 3U RAM4 remote amplifier module is ready to be installed into a 19” equipment 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 loudspeaker enclosure upright in its required position, taking note of the line of the acoustical axis (see Figure 2). Attach the mounting brackets
