3.4.4. Basic MDB Configuration
With the parameters described in Table 3
12, the Mic-
ronas Dynamic Bass system (MDB) can be custom-
ized to create different bass effects as well as to fit the
MDB to various loudspeaker characteristics. The easi-
est way to find a good set of parameter is by selecting
one of the settings below, listening to music with strong
bass content and adjusting the MDB parameters:
MDB_STR: Increase/decrease the strength of the
MDB effect
MDB_HAR: Increase/decrease the content of low
frequency harmonics
MDB_FC: Shift the MDB effect to lower/higher fre-
quencies
MDB_SHAPE: Widen/narrow MDB frequency range
(which results in a softer/harder bass sound), turn
on/off the MDB
