Installation NOTICE! Possible property damage by magnetic fields Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate distance to devices that can be adversely affected or damaged by an external magnetic field. Use the speaker always having a high-pass filter with a cut-off frequency of at least 70 Hz at a slope of at least 18 dB/oct.
Installation 4.1 Tips on handling speakers We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐ ence unobstructedly. It will often be helpful to mount the speakers on tripods. Thus, the sound will be evenly spread with maximum range throughout the audience area.
