Why is NE5532?
The NE5532 is a dual operational amplifier. There is a high-performance low noise. It compares with a most standard operational amplifier like 1458. It shows better low noise performance.
To improved output drive capability, and considerably higher small-signal and power bandwidths.
NE/SA/SE5532/5532A: Internally-compensated dual low noise operational amplifier
They are suitable for application in high-quality and professional audio equipment. For example instrumentation and control circuits, and telephone channel amplifiers.
This op-amp has internally compensated for gains equal to one. If very low noise is important.
We recommended you should use 5532A version. Because it has guaranteed noise voltage specifications.

Why you listen to music is low down. Both everything is normal. But you don’t have a preamplifier. If you have it in your hand, try it now. You can select various input signals. By twisting the selection switch on different expansion rates. For example, Pre mic
NE5532 tone control circuit
The NE5532 is good at making preamplifier with tone control. You can often look at them on a HI-FI sound system. Why should use it? Because they adjust the sound frequency you want.
For example, you love ROCK / Heavy Metal. You want to adjust the bass a lot. And set treble to lower. You can use this its function.
Important! Must be free from any interference. Which the NE5532 is the best choice for you.

Sometimes you need more detailed sound quality. I have two options:
Buy high-quality speakers But very expensive
Use Graphic equalizer to helps us to tune the sound so well. I like the graphic equalizer in 10 channel adjustable. The frequencies of 50Hz, 200HZ,800Hz,3.2kHz and 12kHz.
