It lets press hook their recorders, cameras, andsystems up to ours so they get high-qulaity sound right from our mics instead of from the crowd.
Be sure to sound check before the conference starts but after the crews are set up, they will need to adjust their equiptment to match our signal levels.
If using a mixer, keep levels consisten using the sound meter lights.

at this press conference 7 cameras plugged into to our box.
