Tie Terminal 2 through C1 (0.47uF) to Ground. Add R3 and C1. Use formulas provided to calculate settings, or contact Knowles for support. Setting Gain Formulas: Gain of non-inverting Op-Amp is determined as: G=1+ {R1 / (R2 + R3)} Gain(dB) = 20 * log(G) High-pass-filter Corner Frequency: C.F. = 1 / {2*p*(R2 + R3) * C1} Knowles Acoustics, a division of Knowles Electronics, LLC.
