Just curious - were the manufacturer-specified parameters specifically for the DR480?  If not, differences in calculation and terminology can make different processors sound different.

I agree with the general consensus though - it's usually pretty tough to improve on the manufacturer's processing parameters, and many installations where that is tried end up worse off than just sticking with the recommendation.

The speaker cabinet and the processing are developed as a system, to be used together.

After the manufacturer's preset is applied further eq should be one either with an external eq, or with the input eq of the processor. Individual passband eq should be left alone, as should passband delay.

That was what I as a novice would have assumed and was surprised when I looked at the actual settings in our processors that it wasn't the case.  Perhaps I'll get some help from someone with some skills/experience and see if applying the EAW presets to each passband and then just using the DR480 input EQ to try to "tune" the system to the room makes a noticeable improvement.

I guess I don't know but I would assume the EAW settings were optimized for their processors (MX8750, UX8800) but I don't know for sure.  I guess it wouldn't be for the UX8800 because anyone with these boxes and a UX8800 would use the Gunness processing.

Thanks for confirming my thoughts on the general consensus approach to this guys.

Rob Spence:
I just scanned over the thread and didn't see a statement of a problem needing to be fixed (I may have missed it)?
Why mess with it if it is working?

Loren Jones:
Rob,

You are right, nothing specific is really wrong.  I've just been curious if we are getting the best we can out of our system or if there is any room for improvement by fine tuning system EQ, delays if any etc.  Also, there are no limiters implemented in the system processing.  I would think it would be wise to put that in place just to prevent system damage due to runaway feedback etc.  Nothing really that wrong just wondering if it could be better.

Thanks,
Loren Jones
