Public Address, Tannoy systems for large outdoor areas. With a blend of speakers situated in the most effective manner we can guarantee your whole audience will hear. There will be no feedback, the volume levels will be comfortable and the Key with Demos is we use digital delay units to nullify the echo effect of spaced out speakers. So where ever you are standing you get a coherent Intelligible commentator through the speakers.
This takes a bit of extra work to achieve but well worth the results as you end up with a time aligned Point source structure throughout the venue.
