2X50W Dual Sound Digital Amplifier Board 4-24V

Features 1 Finger size suitable for small space embedded output more than 30W need to add heat sink 2 Boot popular sound 3 Amplifier work no current sound Try to enter the wire is not clear If there is a noise current sound signal input the noise signal will be amplified 4 CS control shutdown current is only 0 4mA Power on quiescent current 28mA 5 High gain amplification 36DB Very suitable for weak signal amplification eliminating the need to increase pre amplifier reduce costs Computer audio input amplifier must be changed to 20DB gain use 6 With output short circuit protection Troubleshooting immediately resume normal work 7 A variety of product pins and size is fully compatible Benefits of using 36dB of power amplifier gain Because the sound source signal of some audio equipment is too weak the amplified sound with 36dB power amplifier will be very loud and the amplified sound with 20dB power amplifier on the market will be very small For example the output audio signal of a mobile phone is weaker than the audio signal of a computer Amplifying the sound with a 36dB amplifier is very large If you use a computer audio signal use a 36dD amplifier to amplify the sound too much and the sound is distorted You should lower the volume of the computer If the computer is not easy to adjust you can reduce the volume by inputting a series resistor on the amplifier board the input resistance of the amplifier board is 1K Use the resistor divider to cha
