3.7.3
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
3.7.4
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.
Figure 12.
Bass normal and DC Mode @ Gain = 14dB, fC = 80Hz
Note:
The center frequency, Q and DC-mode can be set fully independently.
