What is the name of the device pro-stage audio tech's use to send noise through the PA upon initial set up in a room(venue) to do the initial setting of the system? How does that work? Does anybody here use this?
It is called a Real Time Analyzer. It uses "
Pink Noise" to set a rooms EQ flat. Pink Noise is a sound that carries equal amounts of noise power in each octave. A special calibrated mic can then "listen" to that noise and detect differences. Since the noise is equal across the spectrum, if the mic pick up inequalities you know it is the room causing them and you can adjust an EQ to compensate.
