Re: reducing vibration

2003-03-02 by liberatusvirus <liberatusvirus@yahoo.com>

Steve,

I sent a reply to your latest post about 10 hour ago, and then an 
hour after that, but neither showed up. Take 3:

Crosstalk is the result of vibration along the rack. The rejection 
parameters in a module or interface don't eliminate vibration; they 
simply mute a pad, for a split second, to protect it from 
sympathetic reaction when another one is hit--provided both triggers 
are connected to the same unit. In other words, crosstalk doesn't 
occur inside the module, even though the remedy for it does. That's 
why crosstalk between pads connected to the dtx and the PM-16 is so 
problematical; the triggers have no electronic common denominator to 
ensure their independence. If you place your cymbal on a separate 
stand, you will thereby solve the problem, at the cost of 
complicating your physical setup a little. For example, many of us 
place our snares on a separate stand, to allow, among other things, 
ultra-sensitive trigger parameters completely oblivious to the 
threat of crosstalk. As I said before, the best, or most economical, 
defense, however, would be to group triggers on the dtx and the PM-
16 according to their crosstalk susceptibility.

something else on the DTX.  If I disconnect the cymbol cable, I get 
a pure sound on the toms.  I also don't get the crosstalk all the 
time, usually when I first strike the pad.  Also, I am not having 
this problem with other toms connected to the PM-16, just the ones 
that are connected to the rack right next to the cymbols, that's why 
I thought it might be a vibration thing going on.  If it truly was 
crosstalk and I connected the cymbols to a floor cymbol stand then I 
should still have the problem, correct?  If the problem went away, 
then it is vibration and not crosstalk, correct?  Unfortunately, I 
just practiced with my band last night, so my drums are not 
currently set up.
