After I helped out at the 2017 regatta the committee asked me whether I would supply and operate all the audio for the event and of course, I said yes…
There are 3 PA systems needed for this event, a PA system in the marque for the race briefings and awards, the Fireworks PA system for the firework display and the Main PA for throughout the day for the race announcements and commentary.
With the Main PA System, I used my 100V Line stock to put a couple of horns on the barge that I was using as a base for everything. this is pretty much the centre point of the event and means I can get sound too pretty much everywhere if I set up on here. but just to be safe that I had enough coverage I set up some small 8″ speakers on the pontoon just to provide some extra reinforcement.
The fireworks PA system was based on the pontoon and was set up after the main races had finished. On Friday myself and my team set up the system and created a loom of cable that we could run out when it was time to set it up again this made it really quick and easy. I had 4x EV ZLX12p’s and 2x 18″ Subwoofers that just about did it! I used my Behringer X1832USB desk to control it all with 1 mic input, 2 channels of fireworks music and another 2 channels of playback from my mac for generic music and the torchlight music.
The Marque PA is just two speakers and a microphone.
I managed to link all 3 systems together via cat5e cable and some software called ‘Dante VIA’ this allowed me to put a laptop at each PA system and connect them all to the same network, attach an audio interface and transmit and receive audio from each PA system. This meant that I could transmit all the announcements though every PA system at the same time with pretty much no latency.
Overall the event went well and had no major issues at all.
