[BC] RE: Studio Grounding Info

[Martin Sims*]

Hi Mike,

That was a fantastically useful response to my post, thanks so much. I
appreciate you reminding me of the importance of specifying the difference
between "audio common" and "ground". Mostly you confirmed that I'm on the
right track.

In answer to your valid question about why "analog"? The specific answer is
that the current had already limited itself to analog before I was called
in. They had already ordered equipment so it's a bit late to turn back. More
broadly, here in South Africa for many small and medium size installations
digital is perceived as (and often is) to expensive. The skills base amongst
users is limited so the benefits of a more flexible and future-proof system
are often not understood or appreciated whereas the costs implications are.
Skills versus cost is also a real factor upon installation and operation. A
single Axia line node locally costs the equivalent of a wireman's monthly
salary and he can solder a lot of analog wire in a month, whereas the more
"advanced" skills required to set up and run digital systems are hard to
find and expensive locally.

I'm going to get a copy of the NAB handbook now.

Regards

Martin
