As the name suggests a preamplifier circuit pre-amplifies a very small signal to some specified level that can be further amplified by an attached power amplifier circuit. It basically acts like a buffer stage between the input small signal source and a power amplifier. A preamplifier is used in applications where the input signal is too small and a power amplifier is unable to detect this small signal without a preamplifier stage.
You are wrong. Let's discuss. Email me at PM, we will talk.
