The job of a preamplifier is to turn a low-voltage, high-impedance signal susceptible to signal degradation, into a higher-voltage, low-impedance signal. This process is often referred to as adding gain, and preamplifier specifications often refer to how much gain the preamp provides without introducing audible noise. The output of the preamplifier can then be safely sent along to a power amplifier that will raise the current to levels that can drive speakers.

How will you locate fault in preamplifier?
To locate a fault in a preamplifier, start by visually inspecting the circuit for any obvious signs of damage, such as burnt components or loose connections. Use a multimeter to check for proper voltage levels at various points in the circuit, comparing them to the expected values. Additionally, you can employ an oscilloscope to analyze the input and output signals for distortion or irregularities. If necessary, isolate sections of the circuit to narrow down the fault further.

What does a preamplifier do?
A pre-amp is a type of amplifier used in sound systems. It usually amplifies the signals coming from microphones or low amplitude signals coming from any other sources. The pre-amplified signals can then be amplified to a greater extent when the signals are sent to the main amplifier. Because some microphones are low voltage or are wireless the signals are weak compared to older style microphones.
