MECHANISM TO PREVENT EXCESSIVE VOLUME
LEVELS OF MIC MASTER VOL CONTROL AND
MUSIC VOL CONTROL
Although usually the volume level can be varied from level
0 to a maximum level of 10, this feature allows you to
change the maximum volume level to the required setting
(such as up to 7, 8, 9, etc.).
Setting procedure
·
1. Remove the volume knob.
2. Remove the screw behind the knob, then reinstall it to
the required maximum level.
U
The MIC MASTER VOL control knob and MUSIC VOL
control knob cannot turn more than the position where
the screw fixed.
Please set the maximum volume level to prevent over
leveled driven and to protect speakers.
CAUTION:
Please connect higher power handling speakers when
you use this amplifier DAR-800II.
The maximum power of DAR-800II is over 360W/CH
peak.
Please adjust each volume to obtain proper sound level
by confirming the Input peak indicator and the Peak level
indicators to prevent over load level and distortion. It
should be avoided handling the highest power and over
distortion since it would cause the trouble of the system.
Never listen the sound near the speakers because the
high sound pressure level will lead to ear problems.
DOOR LOCKING
The front door is available to lock from door opening for
holding each setting adjust.
To release the door lock, slide the lock lever on the
bottom of the front panel.
Push near the markin
g

BASIC OPERATION
1Depress the power switch (˘) of this unit and other
equipment.
2Connect the required number of microphones.
3Set the karaoke music machine to the play mode, then
set the MUSIC VOL control to the required level, by
checking the Peak level indicator of music input level.
4Turn the MIC VOL controls and MIC MASTER VOL
control to balance the level with that of music source,
by checking the Peak level indicator of mic input level
(MIC 1/A, 2/B, 3.MC).
Notes: 3and 4
If the peak level indicator blinks with red, input level is too
high, then reduce the input level by adjusting MUSIC VOL,
or MIC MASTER VOL controls.
5Adjust the echo level as required.
6Adjust the pitch using the key control buttons.
Now that the required setting is over, you do not have
to operate this unit. All you need to do is to operate the
music source equipment.
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.
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.
Provide a space of
approx. 5 to 10 cm.
Leave the proper space.
Do not use the microphone toward the speaker as it
•
may cause the feedback (howling).
