In speech mode (not recommended for use in music), an additional gain of up to 12 dB can be
achieved compared to bypass mode before sound feedback occurs. Speech mode (5 Hz frequency
shift) is faster and more effective than music mode in terms of feedback.
1.3.2 Four input voice tracking (Auto Mix mode)
Dual input automatic mixing mode
In this mode, the automatic mixing function is enabled(refer to 1.1).
1.3.3 Process with bass lift/Process flat
Due to the natural reverberation of the room, for example, the voice of the speaker usually
sounds full. As feedback suppression, the use of de-reverberation algorithms can filter and reduce the
room's reverberation, which may cause the room's low-frequency response to be less obvious,
especially in larger halls. Provides a "bass lift" option to correct this phenomenon.
1.3.4 Accurate mode/Fast mode
The adaptive filter can be switched between fast filter mode and accurate filter mode. The
accurate filter mode is suitable for the situation where the microphone position is fixed. For example,
the acoustic environment on the stage will be more stable, and the convergence speed of the adaptive
filter will become slower, thereby further suppressing the reverberation component.
In the fast filter mode, the system converges faster. Therefore, this mode is suitable for
situations where the microphone position changes over time, such as when a handheld microphone is
used or in a discussion system with multiple switching microphones.
