  • Page 14: Tips On Handling Speakers

    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.
