| That is the circuit, the component values need to be calculated. Try my high-pass filter designer program on my website in the utilities section. www.readresearch.co.uk note that you will need to keep fiddling F3 to arrive at your desired Fx (which is plain F on my program). |

Ok, thanks. I haven't looked yet, but are any of there active. that is what i would like. I would think it would need to be, to boost the amps output.
Thanks
