1、 Tuning skills:
1: About the microphone howling.
Generally, microphone squealing is caused by excessive volume of the microphone. You should carefully check whether it is caused by excessive total volume of the microphone or by excessive volume of individual microphones. Another reason for microphone squealing is that the sound quality of the microphone is too high. Listen carefully to the frequency of the squealing: the very harsh squealing is caused by MIC TREBLE (microphone tweeter), and the microphone tweeter must be reduced. If it is a very low squeal, the squeal that feels a little vibration is caused by excessive MIC BASS (microphone bass), and the microphone bass must be reduced.
2: In general, that is, during the business period, if the customer requests to adjust the light and heavy reverberation, try not to adjust the REPEAT or DELAY in the reverberation effect, just increase or decrease the ECHO VOL!
3: The volume of computer music accompaniment shall not cover the singing voice of guests. Otherwise, guests will find it hard, laborious and laborious to sing.

1: Total volume of reverberation: ECHO VOL This knob can control the direct sound size of reverberation echo, that is, the amount of the whole reverberation effect!

Note: There are three microphone volume control knobs below the total volume of the microphone, which can control the volume of each microphone separately: MIC1 (volume of microphone 1) MIC2 (volume of microphone 2) MIC3 (volume of microphone 3). Try not to adjust it separately.
