R2 provides up to 12-dB boost or cut at center frequency determined by values of C1 and C2 as given in table.Uses Precision Monolithics OP-08 opamp. Low input bias current of opamp permits scaling resistors up by factor of 10, to reduce values of C1 and C2 at low-frequency end. Same circuit is used for all 10 sections of equalizer, which together draw only 6 mA maximum from supply.- Precision Low Input Current Op Amp, Precision Monolithics, Santa Clara, CA, 1978, OP-08, p 1.
