7 band equalizer

**broken link removed**

Anyone can help me make that 10 band equalizer to 7 band equalizer?

What are the things i will remove?

Also,can anyone give me the corresponding values of the resistors in that equalizer?

Thanks lot!

you'll have to recompute for the bands...also your circuit seems to be so complicated, using too many op-amps...to have a better output just cascade a high pass and low pass filter and you'll adjust them to your prescribed frequency...just remember that your 5th band should attain a 1kHz frequency...

Like I said on the other website, you need simple Multiple-Feedback-Bandpass filters, not a highpass filter followed by a lowpass filter, millions of buffer opamps and two opamps without any negative feedback.

I will be using an NE5532 for the op amps with single supply, will it work if I will ground the -Vcc or do I need to follow your sticky?

No, you generally can't just ground -ve, you need to follow those examples.

would the configuration not affect the performance and computation of the equalizer?

No, as long as it's correctly done - however, this is a pretty naff equaliser anyway - the normal (and better) way uses gyrators.
