EQUALISER for WIRED / WIRELESS MICROPHONE and MUSIC

EQUALISER adjustment is actually used to increase or reduce the high/medium/low frequency component of the 
speaker’s restored sound. It is so-called raising or attenuating TREBLE/BASS via frequency-specific volume knobs to 
improve human voices or make musical instruments’ sound more prominent. According to the scale marks on the panel, 
clockwise adjustment is to increase and boost and opposite direction to decrease and attenuate.

Adjust the level of high frequency (TREBLE) and low frequency (BASS) respectively. All signals have been balanced by the 
high and low sounds after entering the amplifier so it is not necessary to adjust the EQUALISER during the output to the 
speaker. It is recommended to maintain the position of BASS and TREBLE at 12 o’clock.

Adjustment Reference:

BASS:

 It is the basic part of the sound. It accounts for 70% of the entire audio energy and is an 

important component to display the music style. When appropriate, the BASS is relaxed and the sound 
is full and soft. If you feel the sound is thin, you can moderately increase the BASS. If you feel the sound 
is muffled, not clear, or too nasal, you can moderately reduce the BASS.

TREBLE:

 It’s the frequency that affects the sound layering. If you feel that the sounds of instruments 

such as Piccolo and Flute are too prominent, or the tooth sound of the voice is too heavy and the tone 
is sharp, you can moderately reduce the TREBLE.
