Hi "T"!
We agree again on many things. Most of my experience with RTAs is using
the IVIE test set, which allows some windowing of the sample to allow
for time delay before measuring. A key thing in the measurng is the
calibrated mic, knowing just where and how extensive the errors in the
measuring really is. Even nicer if you could input this and
automatically correct the display.
While I've heard of the Meyer's system, I haven't yet had the chance to
use it or mess with it yet, but would love to try it out sometime. I
have a copy of the Tecron manual around here yet from the original
system when I had a chance to use it on the State Capitol Restoration
project here. Speaking of which, i just got a catalog from them
yesterday about a line of power amps they make (they ARE part of Crown
afterall(and thusly Harmon Intl.)) intended for things like MRI machines
and stuff like that. I presume that it is that much better than the
normal Crown line. On another totally unrelated note, I noticed that
Mackie now makes an 80 Amp power amplifier. Not watts, amps.. not sure
what the power supply rails are like, but I think that it is around 2000
watts. A number of other nice features built in.
There are a few other interesting test sets out there including Audio
Precision (just got a new catalog from them, too). I do prefer using an
Energy Time Frequency type of display.. it makes more sense for most of
what I do, particularly when it comes to finding and correcting room
anomolies.
