Wat is the difference betwee an amplifier and a pre-amplifier? VerifiedAn amplifier is often an integrated amplifier, with pre-amplifier and power amplifier in one device. A pre-amplifier regulates volume and sometimes balance and tone and lets you choose what source is used (cd, tape, turntable, etc). A pre-amplifier often provides a little amplification, just enough for the power amplifier. This is an active pre-amplifier. Sometimes a pre-amplifier does not amplify, making it a passive pre-amplifier.
