Please note that noise will happen in these situation:
(1)Hardware problem:
-Power supply is not sufficient or not stable;
-Using switch power supply
-Using transformer as power supply and without shield & isolation; wdo not avoid interference
-Local at the environment with electromagnetic interference
-Audio input has its own problem
(2)Software problem:
-Audio driver setting
-Music Player effects setting
Solution:
(1)Hardware problem-> The power supply should not be placed too close to the amplifier board in order to avoid electromagnetic interference. It is better to use high quality power supply which offers stable power. If you use power transformer, using an iron sheet to cover the transformer is highly recommended.
(2)Software problem-> When you connect the amplifier to telephone or computer, you can turn off the special effects software or sound card driver effects settings. Using the software after making sure they will not take effect on the sound effect.

In Stock & Ready to Ship
Description
This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8 speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic "LM386" amps!
The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin to ground. The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.
Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or greater impedance speaker.
