Re: output impedance of a patch and DI ???

2006-07-07 by bouyakaboy

The problem is not the cable length but the impedance matching !
Have you ever try to plug a bass or a guitar directly into a "line in"
soundcard or a mixing console ??? The song is awful because the output
impedance of these intruments is very hight (Mega Ohm) ! Even with a 2
or 3 meter cable length ! And it drops lot of frequencys :-(
But with a DI witch low down the impedance the sound become cleaner
and beautiful.

So, the output impedance of a A-100 VCA or mixer seem's to be 10Kohm,
and it's pretty hight. I Think so that low down it with a DI can
improve the sound quality of a A-100 patch. That is the question ! 

Best regards
Julien.
