*Secondly, if you need a high-Q compensation, you might not be able to select the frequency at all. I.e. the higher Q you use, the better frequency precision you need.
True, but it's kind of a moot point: Notch filters arenít useful (or appropriate) for equalizing hi-fi speakers.

Yes, generally I do agree. But sometimes they are needed, even on HiFi. One could argue that high Q noches is not for HiFi, but I've seen a few cases where they have their usage.

Take a look at this plot taken for a B&W DM603 S3 speaker. It had a rather pesky mid centered around 320 Hz which sounded pretty intense. I had to use 315Hz, -3dB with a Q as much as 10.8 without affecting too much around.

Re: Feature request: Equalizer profile for Yamaha receivers


Curious, I can’t imagine why it would have taken a filter that tight for a peak that’s nearly a full octave wide. Since typically a filter designated as half the bandwidth of a peak is required to address it, so a filter a bit less than a half-octave should have been adequate for a mere 3 dB adjustment. Even allowing for “overspread,” a filter in the 4-6Q range at worse (1/3-1/4-octave) should have been more than adequate.

But then, different equalizers “calculate” bandwidth differently, as seen in the graphs at this post.

Regards,
Wayne

Re: Feature request: Equalizer profile for Yamaha receivers

It just hit me: Perhaps the REW smoothing is fooling me and disguising a larger dip due to the heavy notch? That certainly needs to be checked!

*edit* And I have been considering making plots for the processor-only part of the receiver. I.e. HDMI source -> DSP -> pre-out and measure that. Then it would be possible to plot the exact response for the Yamaha Qs

Re: Feature request: Equalizer profile for Yamaha receivers

Great topic. Would be interested to know if any progress has been made on a workaround.

I guess I should assume one could best use the generic correction option instead of any specific EQ brand and model in REW in order to get something somewhat useful for the Yamaha PEQ.

Sure would be cool to know how someone smarter than me does the translation of the REW output into choices in the PEQ. My calibrator says it's pretty straightforward, and for that reason he prefers Yamaha over brands that have fixed EQ like Denon etc.

But of course he does this kind of thing every day. People pay him to fly around the country working on their systems. So he has a bit more expertise and practice than me!

+1. It would be great to have Yamaha's peq profile as one of REW equalizer options. I just bought the RXa 1050 and would love to overrule YPAO by using the manual setting and REW. Thank you for such great software!

It’s really impractical for John to profile receivers, there are just too many of them. For any equalizer not supported directly by REW, the pink noise option can be used, which will allow you to tweak the Yamaha’s filters in real time. I did it for my Yamaha and it worked fine.

Wayne
