Preamplifier

A preamplifier is a circuit designed to specifically boost [mic level] to [line level] with maximal preservation of [signal] integrity.

USB mics have a preamp and an analog-digital converter built in
preamplifiers (and many other audio definitions) are generalizations
- implementations vary widely
preamps can be standalone units, but are often built into other hardware ([mixer]s, audio interfaces, handheld recorders)
labels on [audio hardware] specify expected I/O level standards
