TDA7415CB
Description of the audio processor
4. DC-mode: Figure 7 shows the effect of the DC-mode at a filter gain of 15dB. In this
mode the DC-gain is increased by 4.4dB. In addition the programmed center
frequencies and quality factors are decreased by 25%, which realizes alternative
frequency responses.

Mid filter
There are three parameters programmable in the mid-filter stage.
1. Control Range: Figure 8 shows the control range in the frequency domain at 1kHz
center frequency.
