The resisters of R20 (R23), R21 (R24) can be set the HF Elevation.
1. The setting of the HF Elevation.
The resistors of R25, R26, R27 can be set the Bass Compensation.
1. The setting of the Bass Compensation “H”
2. The setting of the Bass Compensation “L”
(Example)
(Example)
R20 + R21 ≈ 10 kΩ
In the case of R20 = 3 kΩ, R21 = 7 kΩ
HF Elevation ≈ 70%
R25 + R26 + R27 ≈ 1 kΩ
In the case of R25 = 200 Ω, R26 = 390 Ω, R27 = 390 Ω
Bass Compensation “H” ≈ 80%
Bass Compensation “L” ≈ 40%
