2-6. EQUALIZER for WIRED and WIRELESS MICROPHONE and MUSIC
EQUALIZER adjustment is actually used to increase or reduce the high/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 EQUALIZER during the output to the speaker. It is recommended to
maintain the position of BASS and TREBLE at just 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.
2-7. VOICE PRIORITY
Voice Priority operation is only necessary when CD/USB/MP3 is playing.
When the Voice Priority switch is ON, the ducking function will be activated. While the music is
playing, a voice input from either a
WIRED or WIRELESS MICROPHONE
will temporarily
override and lower the volume of the background music and voice could be heard more clearly.
Background music will return to its original setting when no audio input is entering the
microphone after certain seconds. However, if the microphone is not switch off, the reentering of
music into the microphone will also activate the voice priority function.
