Hey there folks,
I had a problem with the LM386 amplifiers I bought. Hooked it to a polyphonic microcontroller-based music generator which has two-channels inside, and I get very bad, static and also hissing noise. Worse, the two channels couldn't mix properly, resulting in the other channel being more louder than the other. The speaker, which has two wires connected on it, when I lifted the speaker some more, the sound went away, and something else overpower the sound output.
I wired the LM386 as shown in the datasheet, the low component count, 20 Gain only. What could be the problem?
