Parameter description

1.Input gain: the input gain compensates for the level difference between different audio sources, thus effectively increasing the level of the lower audio source to maintain consistency.

2.Mixer: a mixer can feed a microphone, music signal, or a mix of the two into the output.

3.High-pass filter: filter out the low frequency part and reserve the high frequency part.

4. Low-pass filter: filter out the high part and retain the low part.

5. Microphone feedback suppression: microphone feedback suppression prevents the microphone from squeaking when the sound is amplified at a high volume.

6.PEQ (quantity filter) : a parametric equalizer adjusts the tone of an audio signal and adjusts any frequency band by centering the set frequency point. "Q" can be used to adjust the bandwidth.

7.HSEOILSEO (second order high/low pass slope filter) : this filter can be effectively used for large-scale timbre control by increasing or decreasing the high and low end of the audio signal. The second-order filter has a slope of 12dB per octave, and all filters have an increase/decrease range of + 12/ -24b.

8.Q (bandwidth) : sets the bandwidth of the parameter equalizer. The smaller the value is, the wider the equalizer curve is (covering a wider frequency range) : the larger the value is, the narrower the equalizer curve is (covering a very narrow rate range for more accurate parameter equalization).This parameter is only valid for frequencies set to the type of "parameter equalizer" as described above.

9.Gain: increase or attenuate the output audio signal, such as: -6db refers to the output audio signal minus 6 db, and + 12dB refers to the output audio signal increased by 12 db.

10.EQ PASS: when "EQ PASS" is selected, the frequency band of the current channel will be flattened and the equalizer will be closed.

11.Voltage limiter: voltage limit is a process to process the dynamic range. When the output signal

reaches the "voltage limit starting level", the voltage limiter starts to control the signal level, which is usually used to prevent the speaker from being damaged by the excesive audio signal peak.

12.Time delay; In time, it synchronizes the signals of different speakers, so that the signals from all speakers can reach the audience almost at the same time, thus reducing the phase problem

13.Echo: an echo consists of several delayed artificial echoes, which are mixed with untreated signals to make the singer's voice more attractive. Flexible setting of echo timing, feedback, and levels can produce the desired karaoke effect.

14.Reverberation: reverberation is similar to echo effect. It enhances the singer's voice and makes him sound more present.

15.Start volume; Set the default volume of the device each time it is turned on.

16. Maximum volume: set the maximum volume that the device can adjust.
