audio preamplifiers A preamplifier circuit with a very low noise characteristic can be built by simply combining a FET transistor with a bipolar one. The input impedance of the preamp circuit is almost the same as the gate impedance of the FET transistor (around 1MΩ) The output impedance at the other end is about 1KΩ.

As the name suggests itself, a preamplifier is an audio circuit which is used before a power amplifier, or between a small signal source and a power amplifier. The job of a preamplifier is to raise the level of the small signal to a reasonable level so that it becomes suitable for the power amplifier for further amplification into a loudspeaker.

The NE5532 Preamplifier Circuit. The IC1 is set in non-inverting mode. So, the input and output have in phase the same. And, the output gains at pin 1 depends on R3, R4, R5, R6, and R2. Next, You can choose only one input channel by rotating switch-S1. Which each input channel has a different amplitude.
