TDA7377 2.1ch Amplifier Single Power Computer Super Bass 2.1 Amplifier Board 3 Channel Sound Amplifier DIY Kit
Tax included.
Description:
Operating voltage: AC 9-12V Or DC 12-18V
Current: 1A(better than 2A)
Please assemble it refer to the PCB mark.
Impartant Notice:
1. We recommend sufficient power supply, electric current the bigger the better. Suitable speaker&box is equally important, should not be forgotten.
2. Please attention phase of each channel, otherwise potentially reducing efficiency.
3. It is a traditional amplifier, it will heat at work, you can install a fan to cool down.
4. DC out terminal is from the master power, have to be careful to use.
5. How do you judge the sourse of hiss(noise): short circuit the signal input, then monitor the speaker output, if it have no noise, the amplifier is normal; in other word, if the board is connected to PC or mobilephone have some noise, then the noise were from the PC or mobilephone.
