Re: When setup is important?



Yes I have said that many times.  The people who "dis" combfiltering-are simply nieve.


It is not this big "Ugly twisted" type of sound.  But rather a "dull-not as clear" type of sound.


You mostly don't realize it when it is happening, but you instantly realize how much better it sounds without the combfiltering.


As I used to say-"back in the 'ol days-combfiltering was never an issue.  I didn't know what it was-so it was not a problem"  HA-HA.


It is not like the sound is not listenable-in fact we hear combfiltering with even a single driver speaker all the time. Any reflection introduces combfiltering.


Combfiltering is not only because of 2 different loudspeakers are covering the same area-but also happens within a single cabinet.  If 2 adjacent passbands arrive at the listeners ear at different times (even small parts of a ms apart-depending on freq) you will have combfiltering.


It is kinda like those Clariton commericals in which they pull the "veil" off of the screen and it looks clearer.  It is not that it looked that bad before-just better without it.


HOWEVER-If a single cabinet will not get loud enough-then it doesn't matter how good or better it sounds.  It needs to be loud enough for the situation at hand.


And we as an industry have just "gotten used to it", but that does not mean it is right. 


It is real easy to play with on a digital console that has delay on the inputs.  Just assign a single input jack to 2 channels-and put a little delay on JUST ONE of them-say 1ms.


Now set the gain/trim the same and turn up both channels equally (assigned to a single output) and listen.  Headphones are a good way-that way you eliminate any possible combfiltering in your playback sytem (reflections or combfiltering within your playback speakers)


This is as bad as it can ever be.  If you reduce the level of one channel-you will hear it get clearer-and when one channel is completely off-it is clearest.
