The aluminium plate and cooling fins of the amplifier at the rear of the active subwoofer serve to cool the built-in amplifier; for this reason, they must also be at least 5 cm away from all objects and must not be covered (e.g. by a curtain). The bass reflex opening(s) on the active subwoofer must not be covered (e. g. by curtains, etc.) in order to guarantee adequate ventilation of the amplifier.

THE ACTIVE SUBWOOFER HECO ALEVA GT SUB 322A This subwoofer has been adapted to provide the best visual and acoustic match to the HECO ALEVA GT range of loudspeakers. However, it goes without saying that it may be combined with other loudspeakers. POSITIONING The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That‘s why positioning generally doesn‘t present any problems. However, it is preferable to place the speaker close to the front loudspeaker in front of the listening position. You should also make sure that the distance from the sides and from the rear to items and walls is at least 20 centimetres as otherwise bass reproduction may be impaired. THE SUBWOOFER‘S OPERATING ELEMENTS (FIG. 1) Mains connection (9) The subwoofer is equipped with an integrated amplifier and needs to be connected to a mains outlet by means of the supplied mains cable.
