I guess I haven't encountered that issue as it's "my" pa system
Running both the PA system and the recording system together eliminates
90% of the problems out there. Most of them are political ones anyway,
like whether we use the mike that the PA guy wants or the mike the recording
guy wants.
In fact, if you are running both, there's no reason you can't just use
a PA board with direct outputs to feed the recording rack and save yourself
a whole lot of complexity.
You will encounter PA guys who just plain won't put a passive-Y in front
of their system. It doesn't matter if it is going to cause a problem or
not, they won't even try it.
I guess you would need a way to know this in advanceor put up yur own mics,
the level of PA your talking about (where the operator even knows a passive
from a Iso split) is well beyond the "average pa" I feel the op was
addressing.
Could be.
I invested heavily in iso's and broadcast splits andhave never found the
investment was worth it
with Jensens at around 60$ each it got real expensive real fast
If you decide you want to sell some of those, let me know.
50 channels at 12$ per channel for ground lifts= 600$ for teh ground lifts,
a single 15$ gl adapter would have done the job just fine, or I would simply
cut the ground at the split, my point is it was alot of money for something
that is rarely needed and when needed there are many work arounds that are
under 20$ or even free
This is absolutely true.
On a lot of this stuff I like to build it in 8-channel blocks, that way
you can mix and match. The advantages of having all the grounding stuff
switchable is that it's very quick to flip switches around and change the
grounding configuration when you're in a rush. You pay for that speed.
I also have encountered some really, really scary PA rigs and some scary
backline stuff plugged into PA rigs, and it makes me want as much isolation
as I could possibly get sometimes. I'm talking about measuring 60V ground
fault currents on a cable shield. That goes beyond hum and into potential
injury.
I even bought the scanner that searches for the signature noise of a ground
problem and lights a led on thechannel that is giving trouble, before line
check
a 1200$ option I used maybe 6 times
That seems a little bit over the top, yeah. But you might have noticed that
I am not a fan of automation anyway.
