User manual GENELEC AOW312

[. . . ] 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 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. 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. [. . . ] AOW312 loudspeaker cabinet top view.

The airflow from the port must not be obstructed, and a free space of at least 5 cm (2") is required before the port. Connections Each loudspeaker is delivered with two Speakon cable connectors. There is one Speakon output on the amplifier and two Speakon cable inputs (one on each side) on the cabinet. The inputs may not be used for daisy-chaining several loudspeakers or connecting two amplifiers to a single loudspeaker. Measure the required length of cable and solder the connectors on it. Pins 1- and 1+ carry the signal for the tweeter, pins 2- and 2+ for the mid range driver and pins 3- and 3+ for the woofer. See Table 1 below for recommended cable thicknesses. The whole cable should have an outside diameter of 8 to 20 mm (5/16" to Cable gauge 2, 0 mm2 (14 AWG) 3, 3 mm2 (12 AWG) 5, 3 mm2 (10 AWG) Max. length 30 m (100 ft) 40 m (130 ft) 60 m (200 ft) 13/16") to fit in the Speakon connector. Alternatively, pre-terminated lengths of cable are available from Genelec. Be sure not to mix the amplifier/loudspeaker pairs when installing multiple loudspeakers at the same time. Each amplifier and loudspeaker delivered in the same box are marked with the same identification number and calibrated together for optimal performance. Sufficient cooling for the amplifier must be ensured. Leave at least ten centimeters (4 inches) free space above and below the amplifier to ensure cooling. The space adjacent to the amplifier must either be ventilated or sufficiently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95°F). There are no fans in the amplifier unit so it may be mounted in the listening room near the lodspeaker cabinet using a short cable. Before connecting up, ensure that the mains switch is off. Check that the mains voltage selector is correctly set to your local voltage. Audio input is made via a 10kOhm balanced XLR connector, but unbalanced leads may be used as long as pin 3 is grounded to pin 1 of the XLR. Once connection has been made, the loudspeakers are ready to be powered-up. output of the decoder or other source, by use of the input sensitivity control on the amplifier panel. A small screwdriver is needed for the adjustment. [. . . ] SERVICING AND ADJUSTMENT MUST ONLY BE CARRIED OUT BY QUALIFIED SERVICE PERSONNEL.
