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 ettectively 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 cerfectly, 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 microhpone 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. 3

CONNECTION When connecting the 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 of naked loudspeaker cables. \~-- --'~o:=~ ljjm'!'~ About the impedance of loudspeaker 1;f(O)~ LC~u Right SYSTEMS 1 Left 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 pulling off the power cable, please confirm the left track (L: white) and right track (R: red) and then connect them. The names of the terminals could be different with the device. Please read and refer to the operating instructions to ensure correct connection. If the signals of left track and right track are connected reversely, the stereo effect shall be reduced. 12 1 _

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 carefully. 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.

After operating the adjustors inside the door, please close the door. * Note If too big force is made at B direction, it might damage the structure, do operate properry. 13

BASIC OPERATION 1. Press the power button 1on the panel and you will hear tile sound produced by the relay in 2-3 seconds. 2. Use the volume adjustor 2 to adjust tile volume. And use the timbre adjustor 3 to adjust the timbre. 3. Insert the microphone into the position 4. 4. Adjust adjustor 5 to the middle position. 5. Adjust the volume of microphone through the adjustor 6 and adjust the timbre of microphone through the adjustor 7. 6. Adjust the volume of 1/A, 2/B, 3 through the adjustor 5. 7. Adjust the adjustor 8 to the middle position, and adjust the reverberation time through. the DELAY adjustor 9, and adjust the repeat time through the REPT adjustor 10.. 8. Adjust the reverberation through the adjustor 8. About the protective circuit The product has built-in overload current protection and overheat protective device, which could effectively protect the loudspeaker in case of short circuit. After activating the protective circuit, the device shall automatically cut off the output of loudspeaker and the indictors of microphone and master volume shall blink at the same time. At that time, you must pull off the power plug and check the connection of loudspeaker plug and other plugs. If the device is too hot, improve the ventilation and do not connect the power plug until the temperature is decreased.
