CHARACTERISTICS
Major characteristics of this KARAOKE AV AMPLIFIER are as follows.
Powerful Output Force of Amplifier
The master amplifier comprising the big power transistors features
excellent maximum output power and
I.M.D
to get ideal recovery effect
and provide the perfect hearing effect.
Application of STEREO
ECHO
The function of stereo echo makes the user feels he/she is at the site
and the better accompaniment effect will be produced.
Built-in Feedback Reducer
The built-in feedback reducer could effectively solve the problem of
microphone howling in various environments and prevent howling.
Perfect Built-in Protective Circuit
When the overload current in the amplifier is too big or too hot and
the unit of loudspeaker has short circuit, the built-in protective circuit
shall be activated automatically to effectively protect the device and
loudspeaker.
Sound Quality Improvement Design
In order to recover the sound source signal certectlv, by improving
the noise ratio of signal band to shorten the transfer distance of
signal, decrease the intermodulation distortion of left/right track
and reduce the interruption of signals as well as reduce the effect of
power to the signal source to further improve the output sound
Quality.
Convenient Volume Adjustment Function
It could adjust the volume of rrucrohpone independently and adjust the
master volume and the tracks of loudspeaker respectively.
Auto Input Sound Source Selection
It could detect the external equipment automatically and select the sound
source of input automatically.

PRECAUTIONS
FOR
INSTALLATION
Do not install the product at the following places:
- Bad ventilation or airtight environments
- Near the heating equipments or under the direct rays of the sun.
- Unstable fields
- Damp or dusty fields.
Right installation
The product will produce some heat in working, so it should be installed
at the place where has good ventilation.
Please keep the upper side of device 10cm or more away from the wall,
and
Scm
or more for the two sides; 10cm or more for the rear side.

Before
connecting
Precautions
When connecting, please pull off the power cable from the power
socket and then reconnect, the names of terminals could be different
with the device.
At that moment, please refer to the instructions to connect correctly.
It should use these loudspeakers that impedance is higher than 6
Q.
If it's connected wrongly, it might damage the device and produce noise.
After being installed, if the connection cable is mixed with other cables,
or it's too close to other electric products, noise might be produced.
The product has two power output ways including coupled power output
and uncoupled power output; please select the right terminal in using.
Output power of AC output terminal
The output power of used audio equipment couldn't be exceed the
maximum output power. The power output terminal (Ae outlet) could be
used for the connection of audio equipment only. Do not use together with
other electronic products (such as electric heater and other electric products
whose powers are over than the nominal power).

When connecting tile loudspeaker cable
When connecting the loudspeaker connector,
please confirm the right polarities {+ and

and the right track, do not connect reversely.
Please pay attention to the connection of
loudspeaker and avoid touching with other
terminals or the rear panel.
In addition, do connect the cable according
to the correct polarities and avoid the touch

About the impedance of loudspeaker
If a loudspeaker that has lower impedance than the rated impedance
{6-8
ohms}.
for example 4 ohms loudspeaker. is used for a long time, the built-in protective circuit
may be activated automatically.
After the protective circuit is activated, pull off the cable and keep a good ventilation
to reduce the temperature and then reconnect the power.
When connecting the signal cable
When connecting the signal cable, after White (L)
pulling off tile power cable, please confirm
the left track {L: white} and right track
{R:

SETUP OF MOTOR VOLUME OUTPUT ADJUSTMENT
The user may set up the max. output levels of the master volume of music and
microphone, it may effectively protect the loudspeaker and the amplifying circuit.
The method of setting up the max. output level is described as follows:
1. Remove the knob of the master volume
of music and microphone.
*Precautions for removing the knob
Because the knob and the LED is connected by the cable,
so you should pull it out caretuuy.
2. Remove the bolts first and then fix them on
the corresponding positions again.
If the bolts are too tight, it might cause bad effect.
Please keep the consistence height with the original
position or confirm whether the knob is fixed firmly.
3. Please use the same specification bolts.
Improper bolts might cause disconnection and it's easy
to fall into the machine and which would damage the knob hole.
4. Adjust the knob clockwise to decrease the level.
