    Pre-amps are used for amplifying small amplitude audio signals up to the normal range that's input to a large audio amp, known as "line-level", whose reference level is 1V RMS into a 1K Ohm load.

    Turntables and microphones are two common small amplitude audio sources that can require (depending on the turntable and microphone) a preamp.

    Hope that helps.

    • Can I use a preamp to amplify the signal from a simple ($20) Memorex DVD/CD player before it enters the mixer? Or do I need an amp? The mics on the mixer have their own preamp built in. The mixer is a Behringer 1202FX. I'm using the DVD/CD player as a karaoke player (less graphics)in conjunction with the microphone plugged into the mixer.
