• Do not operate the AVAA in a confined environment: The AVAA is designed to be positioned in a corner of a room with its rear side panels against the walls. However it is important that the rear panel is left with sufficient circulation and ventilation of air for cooling purposes. Make sure there are a few centimetres free behind the AVAA such as in a right angle corner. • The AVAA is designed to work in rooms of minimum 10 m2. It is designed to be positioned in a corner.
3 General Overview 3.1 Description The AVAA is designed to absorb the standing modes between 15 and 120 Hz in a room. Above these frequencies, passive systems are effective. For best results, the AVAA should be installed in a room where medium and high frequencies have already been treated with passive systems. With frequencies below 120 Hz, each operating AVAA will have the same effect as a hole in the wall much larger than the dimensions of the AVAA.
