We recently held an outdoor event at a football field with an in house audio system. How the event worked was that there was a stage on the football field with some vocal mics. On the opposite side of the field, (short way across) and at the top of the bleachers was where the in house mixer and PA system was located. In order to send some of the inputs for the event announcements to the PA system, we used a Wireless SLX4 body pack with a 1/4inch connector patched into one of the AUX outputs on the stage mixer. We had the mic receiver on the other side of the field plugged into the in-house PA system. We had some speakers that we brought in for the event, but the organizers wanted all of the announcements to go through the main PA system, while the vocals went through the speakers we brought in. There was a significant lag between when the speaker spoke and when it went through the PA system due to the long distance between the mic and the receiver. When we do this event again, I wanted to get an idea on the best way to transmit the audio from the board on one side of the field to the other, either via wireless or something that could help reduce the lag time between the mic and the speakers. (It was very distracting for the people making the announcements to hear their voice coming back at them with a delay.) Thanks in advance.
