1. The setting of the HF Elevation.

R21

R20 + R21

Note: please keep the following formula.

R20 + R21 ≈ 10 kΩ

(Example)

In the case of R20 = 3 kΩ, R21 = 7 kΩ

HF Elevation ≈ 70%

• R25, R26, R27

The resistors of R25, R26, R27 can be set the Bass Compensation.

R25 + R26 + R27

Note: please keep the following formula.

R25 + R26 + R27 ≈ 1 kΩ

(Example)

In the case of R25 = 200 Ω, R26 = 390 Ω, R27 = 390 Ω

Bass Compensation “H” ≈ 80%

Bass Compensation “L” ≈ 40%
