Treble Band Circuit
The shelving characteristics for the treble band can be obtained.
The equivalent circuit and the calculation formula during boost are shown below.
• Calculation example
Specification Setting frequency: f = 26000 Hz
Gain during maximum boost: G = 12 dB
Let us use R1 = 12.840 kΩ and R2 = 38.861 kΩ
The above constants are inserted in the following formula.
