Description of the audioprocessor

TDA7418

4.6.2

Center frequency

Figure 10 shows the four possible center frequencies 60, 80, 100 and 200Hz.

Figure 10. Bass center Frequencies @ Gain = 15dB, Q = 1

4.6.3

Quality factors

Figure 11 shows the four possible quality factors 1, 1.25, 1.5 and 2.

Figure 11. Bass Quality factors @ Gain = 14dB, fC = 80Hz

4.6.4

DC mode

In this mode the DC-gain is increased by 4.4dB. In addition the programmed center

frequency and quality factor is decreased by 25% which can be used to reach alternative

center frequencies or quality factors.
