Function
Micronas BASS Amplitude Limit
bit[15:8]
bit[7:0]
The Micronas BASS Amplitude Limit defines the maximum allowed amplitude at
the output of the MB relative to 0 dbFS. If the amplitude exceeds MB_LIM, the
gain of the MB is automatically reduced. Note that the Volume Clipping Mode
must be set to “dynamic” (see page 32).
Micronas BASS Harmonic Content
bit[15:8]
bit[7:0]
MB creates harmonics of the frequencies below the MB highpass frequency
(MB_HP). The variable MB_HMC describes the ratio of the harmonics towards
the original signal.
Micronas BASS Low Pass Corner Frequency
bit[15:8]
bit[7:0]
The MB lowpass corner frequency (range 50...300 Hz) defines the upper corner
frequency of the MB bandpass filter. Recommended values are the same as for
the MB highpass corner frequency (MB_HP).
Micronas BASS High Pass Corner Frequency
bit[15:8]
bit[7:0]
The MB highpass corner frequency defines the lower corner frequency of the
MB bandpass filter. The highpass filter avoids loading the loudspeakers with low
frequency components that are below the speakers’ cut off frequency. Recom-
mended values for subwoofer systems are around 5
sets around 10
