Universal Preamplifiers using – NE5532 – LM382 – 741
You have a good power amplifier and speaker. You are listening to music. But the sound is very light. The problem has many reasons. One reason for the problem is the input signal is too low. You may need a preamplifier using IC. It will make the input signal is higher. Then, You will listen … Read more
