■ How to use microphones properly and
operating precautions
• Keep the microphone approx. 5 to 10 cm away
from your mouth.
• To make the voice sound clearly, leave the
proper space between the microphone head and
holding position on the microphone.
• Do not cover the lower wind screen of the
microphone. As this may muffle the bass sound,
defeating proper vocal reproduction. It may also
cause howling.
2 Connect the required number of microphones.
3 Set the KARAOKE machine to the play mode,
then set the MUSIC VOL knob to the required
level.
4 Turn the MIC VOL knobs and MIC MASTER
VOL knob to balance the level with that of
music source.
(1) Provide a space of approx.
5 to 10 cm.
(2) Leave the proper
space.
Note:
If the PEAK INDICATOR lights, input level is too
high, then reduce the input level by adjusting
MUSIC VOL, or MIC MASTER VOL knobs.
5 Adjust the echo level as required.
6 Adjust the pitch using the key control
buttons.
• When you use the IR microphone system, do not
cover or shade the IR radiation parts (black
plastic window) of microphone at the bottom as
the wireless signal is weakened.
Now that the required setting is finished, you do not
have to operate this unit. All you need to do is to
operate the music source equipment.
• Do not use the microphone toward the speaker
as it may cause the feedback (howling).
