A PRACTICAL GUIDE  FOR  USE ON 5.1 OUTSIDE  BROADCASTS

Only now have the true benefits of SoundField microphones become apparent to the sound mixers 
in the live television community who are now being asked to deliver 5.1 audio and more, to 
accompany live High Definition Broadcasts. Many such HDTV Broadcasts are for sporting events 
where there is no rehearsal and a limited amount of set-up time.

 

 

Where should the microphone go in the stadium? The microphone is simplicity itself to rig and is 
very tolerant of positioning. It has been said that as long as the microphone is in the same stadium 
as the event, the ambience captured will be very enjoyable! However, there are some basic rules 
that should be followed...

 

 

The microphone must be placed at least five metres from any individual crowd members, and in 
such a position so as not to be physically disturbed. Individual claps or voices that are too close to 
the microphone will result in making the rest of the ambience difficult to control. The microphone 
must be securely mounted, generally clamped to a stadium structure, protected from the elements 
(direct wind and rain) with suitable wind and rumble isolation. Generally, the higher and more 
centrally-placed above the main crowd or audience, the better the overall sound experience will be.
