Tone Circuit Constant Calculation Examples
Treble Band Circuit: The shelving characteristics can be obtained for the treble band.
The equivalent circuit and calculation formula during boost are indicated below.
Calculation example 1
Specification
Set frequency: f = 10000Hz
Gain during maximum boost: G+18dB = 17.5dB
Let us use R1 = 6.51k and R2 = 45.19k
Ω
The above constants are inserted in the following formula
G = 20 × Log10 1+
C =
=
≈6500 (pF)
Bass Band Circuit: The equivalent circuit and the formula for calculating the external RC with a mean frequency of
100Hz are shown below.
Calculation example 1
specification
Mean frequency: f0 = 100Hz
Gain during maximum boost: G+20dB = 20dB
Let us use R1 = 0k
Ω and R2 = 66.7kΩ, and C1 = C2 = C.
We obtain R3 from G = 20dB
R2
G = 20 × Log10 1+
2R3
R3 =
=
≈3.6kΩ
We obtain C from mean frequency f0 = 100Hz
f0 =
C =
=
≈0.1μF
We obtain Q
Q =
×
≈2.15
Note item when using
(1) When turning on the power, the setting inside is unsettled.
Before setting control data, it does a mute.
(2) To prevent the digital noise of the high frequency influence a terminal. (SCL, SDA)
It can be protected by a signal line in the ground pattern or by the shielding cable.
(3) To prevent the noise in changing a mode, please set the mute ON.
