AV Discipline: Audio, Sound

AV Category: AV Equipment

AV Jargon: EQ, GEQ, Equaliser, or Graphic

Description: 

The Graphic Equaliser is a signal processing device that is primarily used to “equalise” or “tune” the acoustic response of an audio system. If you have any number of microphones on your event, chances are there will be a graphic equaliser processing the signal to ensure it sounds clean and balanced. It is most commonly positioned at the AV Technician’s control desk for ease of access and connectivity with other audio equipment.

The Graphic Equaliser typically features 31 filters that are able to cut or boost selected frequencies. The filters are adjusted by the AV technician according to the acoustic response of the event space. Maybe you have heard “Test test 1-2” coming over the audio system, that’s the AV Technician listening to the effect of the graphic equaliser on their voice.

Too much of one frequency can sound harsh and cause irritating feedback. Too little of one frequency can sound hollow and cause intelligibility issues! It requires a good ear to get it sounding right. Whilst graphic equalisers are rarely requested, all good AV technicians will ensure one is specified, due to the critical role they play in sound reinforcement. Next time you hire an audio system for your event, ask the AV Technician if a Graphic Equaliser is being used!
