Re: Advice For Measurements


Couldn’t hurt to tame the broad peak at 2.5 kHz some more.

BTW, don’t know if this was mentioned, but above 300 Hz filters for both channels should be matching, not individual.

Wayne

Re: Advice For Measurements

Wayne,
I am curious as to why above 300hz both channels should be the same? What if your two channels differ above 300hz would you still use the same adjustments for both?

It’s because it whacks out the imaging. Any equalizer introduces phase changes at the frequencies affected by the filter – that’s how equalization is accomplished. So if you introduce a change in phase in a certain frequency range in one speaker, but the other, you’ll notice that the imaging is affected.

I typically use pink noise in both channels above 300Hz, and EQ both speakers with a single set of filters.

Regards,
Wayne

Probably should have mentioned, you can use the RTA feature with pink noise and adjust the equalizer and see the results instantly on the screen in real time. It’s faster than “measure – EQ – measure – EQ” over and over, but it’s continual noise instead of a quick sweep. So you’ll probably want ear plugs and send the wife to the mall.

Wayne

Re: Advice For Measurements

Wayne,
Are you meaning for above 300hz using the RTA?

Re: Advice For Measurements

Not necessarily above 300 Hz, just an alternative in general to using the sine wave sweep.

Wayne

Wayne,
I did some adjusting today and wanted to ask you, what does it mean when after measuring the left and right channels independently they both line up perfectly on top each other??? From about 100hz to 10,000hz they are one??? Is this correct or even possible???
