2-5. TONE for WIRED and WIRELESS MICROPHONE and MUSIC
TONE 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 HIGH (MAX) / BASS (MIN)
via frequency-
specific volume knob to improve human voices or make musical instruments’
sound more prominent. According to the scale mark on the panel, clockwise adjustment is to
increase / boost high frequency and decrease / attenuate low frequency, opposite to increase /
boost low frequency and decrease / attenuate high frequency.
Adjust the level of high frequency (MAX) and low frequency (MIN). All signals have been
balanced by the high and low sounds after entering the amplifier so it is not necessary to adjust
the TONE during the output to the speaker. It is recommended to maintain the position of TONE
at just 12 o'clock.

Adjustment reference:
◼
MAX (TREBLE)
: 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.
◼
MIN (BASS)
: 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.
2-6. ECHO for WIRED and WIRELESS MICROPHONE
This function can add extra depth to the sound of
WIRED or WIRELESS MICROPHONE
to
create a realistic acoustic ambience. You can adjust the reverb depth by using the ECHO knob.
The depth range is from MIN through MAX. The MIN level produces no effect, while MAX level
produces maximum reverb depth.
