The chips were probably moving in relation to the camera's optics - a remote
Pan/Tilt/Zoom system would allow the cameraman to be further away. I value
my hearing too much! 

This reminds me of a fictitious group called Disaster Area whose instruments
were so loud that they were played remotely from a space ship orbiting a
different planet. Legend has it that their concerts were best listened to
from a concrete bunker in a different continent. Apparently they were banned
from several worlds because their PA system exceeded Strategic Arms
Limitation Agreements in place in various galaxies.

More seriously, I was invited recently to a demonstration of some new
speakers by B&W. I was very impressed, then I found out that I was listening
to £ 18,000 worth of speakers and £ 50,000 worth of Naim Amplifiers. With CD
players and turntables and so on there was almost £ 100 K's worth of gear
there. (I'll have two please!) I ended up picking holes in the mix and
recording of the pieces we were listening to. I know of few music studios so
well equipped. Now where did I leave that £100K?
