If we want good quality sound system,the first thing to consider is that a good pre-amp.
Some people say that’s not necessary. But when the low-level audio source.
We may need to adjust the sound too high will cause distortion.
so should have the preamplifier to amplify a signal up before to the our power amplifier.
And I use transistors to build as small pre-amps because.
1. I am familiar with it than other devices. Even though the quality is good.
2. There are many to choose from build circuits.
3. Lower noise. Compared with ICs.
4. Cheap, easy to find accessories.
Seeing these advantages. Let’s consider circuits different example, I would suggest the following. […]
