Functional Introduction:
1.Uses advanced effective power amplifier circuit;
2.Each input has independent volume controller, with treble & bass volume controller;
3. 1 channel MIC input, 2 channels line inputs;
4.Has constant voltage & resistance modes, constant voltage output is 100V/70V while constant resistance output is 4~16Ω;
5.Built-in MP3 & FM radio players, can shift play modes freely;
6.Supports U disk and SD card, convenient to change a song, remote controller makes it easy to operate.
Advantages:
1. +5V or +12V power supply optional, common model;
2. Electronic volume function;
3. FM tuning is optional;
4. MP3 audio format play;
5. With AUX input, supports LED display control;
6. Small volume, easy to install.
Note:
1. The volume should not be too loud, or the tone will be distorted;
2. Please low MIC volume to minimum when insert it;
3. Please power off when connect a speaker cable, insert or pluck signal cable;
4. Can’t short-circuit when connect a speaker cable;
5. Don’t block up the air vent;
6. Stop to use the machine if power cable is torn;
7. Don’t put the amplifier under places below:
Bad airy; dusty and wet; direct sunlight; high temperature or near to heat; quake-affected places
8. Case must safely connect to earth;
9. Keep it’s airy. If the protect led keeps light after power on and signal input, it means that there’s short circuit on output cable; please turn off the power at once, power on it again after malfunction removed.
