R.A. Meuser claims a good analog board will cost over 10K
Nonsense! Not for radio use. Our Wheatstone RE55 12 channel was in
the 6k range 2 years ago; has more than enough features for what we
use it for--production. We have 14 channels in our control room
board--an Auditronics 2500, we could probably replace that new with
the same features for around 7500--List. I don't think I could find
anything over 10K I would need. Indeed, a quick look at the BSW
website shows only one 18 channel analog board over 10k (and that by
only a 100 dollars). Plenty of fancy digital consoles up into the high
twenties, though.
We don't need six dedicated channels anymore for two three stacks. I
have three mike channels in the control room--use them all only in the
fall for one live scoreboard show Friday evenings. Perhaps TV or a
recording studio would be able to make use of the large custom
mixers--but even in live TV once you get past 5 or 6 mikes, you don't
have the 5 VTR's and two film chains like the old days. Spots and
actualities are coming from a hard drive.
I will certainly agree that there are advantages to digital systems in
multi-studio complexes. Digital systems--not consoles--you just need
control services with 3 or 4 local analog inputs (mikes, phone, 360
system or similar device for drop-ins) with everything else sent back
from the racks. But for simple installations of three or four studios
in a core area analog consoles are far cheaper and just as good.
Getting back to the original topic--grounding:
1. Go with a good system that will work with your physical plant's
limitations.
2. Don't ignore lightning and surge protection; we have a third world
electrical system in many areas of the country.
3. Ignore any schemes that call for cutting off or floating ground
(third wire) plugs. Some manufacturers run the electronics off a
transformer or other scheme isolating the neutral--then sink current
into the third wire & chassis. Can get interesting if the device is
not properly (electrically) grounded.
