The Mic section has 11 customizable EQ bands, helping to customize signal cut off for microphones, 

used to cut feedback or compensate for lower signals.

EQ 1 -> EQ 2: 

adjusts bass frequencies from 63Hz -> 125Hz

EQ 3 -> EQ 8:

EQ 8 -> EQ 11:

Depending on the type of music, different types of speakers, different room spaces, different adjustments 

will be required suit your karaoke set

Depending on each person’s voice and depending on the type of microphone, you can use the following 

basic adjustments:

• For people with a deeper voice, you should reduce the intensity of bass (in the frequency range of 125Hz 

and 250Hz) to avoid the sound being Um.

• For those who have a thinner voice, you should increase the level of bass (in the frequency range of 60hz 

and 125Hz) to thicken and add warmth to their voice

• If your speakers have mid frequencies that are more pronounced than bass and treble, you can reduce 

the mid frequencies (250-Hz-1000Hz) to get a more even sound. Conversely, if the speaker has bass and 

treble that over power mid frequencies, you lower these 2 frequencies so that vocals do not “boom” and 

are less harsh. This helps cut feedback on microphones, enhance singing voices.
