response curve be desired. A combination of internal

resistors and external capacitors determine the

response of the circuit.

Use the following equations to calculate the external

capacitor values for the desired 3dB frequencies:

where R

BPOT

, nominally 116kΩ, is the bass poten-

tiometer (see Figure 7).

where R

is nominally 3.5kΩ (see Figure 7).
