If you’re a videographer, consider a standalone, minimal mic preamp. The Focusrite Scarlett Audio Interface is particularly well-known for its preamp’s headroom as it boosts mic levels for use in your computer’s digital audio workshop (DAW).ĭAW audio interfaces are not the only devices that feature mic preamps.

That’s the ability to crank up gain without deteriorating the signal into distortion. The gold standard for mic preamps is ample “headroom”. And not the good kind of guitar distortion. If you turn the gain up too much on a condenser mic, you’ll wind up with distortion. Dynamic and condenser mics may need a bit less gain than weaker ribbon mics. Most performers do the tweaks with the “gain” control on a preamp, audio interface, or equalizer. Getting a good, clean line-level from your microphone takes some tweaking. But mic users typically want sound quality with more transparent clarity and cleanliness. They’re able to adjust highs, mids, and lows, and boost classic rock-style harmonic distortion. Guitarists love different preamps for how they shape tone coloration. Either one can make your small amp sound like a booming Marshall stack. Guitar preamps are so essential for tone that many guitarists prefer to have additional external preamps in pedal form, like the Boss Acoustic Preamp or a high-end tube-driven model by Koch. Those add-ons prepare the signal for subsequent effects like reverb and compression before it hits the power amp and speakers. also shape the tone of the line-level signal, adding a bit of gritty overdrive or distortion. Good preamps built into guitar amplifiers, like this tube-driven Vox 15W model. As we’ve explained, your guitar’s signal goes straight to a preamp, which amplifies its weak magnetic signals to line-level.īut this is only the beginning for the magic of guitar preamps. Yet there’s usually a preamp already built into whatever amplifier you’re using. The preamp occupies a specific role in the signal chain of instruments, like electric guitars. Without getting into the electronics and circuitry that differentiates preamps, we can lump them into three broad categories: microphone preamps, instrument preamps, and phono preamps.

Now that we know what a preamp is, we can briefly discuss the different types. So whether you were fully aware or not, you may already own a preamp. The good news is they’re already baked into basic digital recording equipment, like audio interfaces. Well, if you own an XLR microphone and want to record with it or use it to amplify your voice for live streaming, you’ll need a preamp. For live PA systems, you’ll need to add a power amplifier to your signal chain, too. Even line-level signals are not enough to drive loudspeakers. If you’ve ever tried to plug an electric guitar or microphone directly into your laptop, even with the right cable adapters and converters, you’ll realize the need for a line-level signal immediately.Ī preamp uses transistors, or less commonly old-school vacuum tubes, to boost these analog low level signals up to line-level. None of these low-output signals are “line-level,” which is the bare minimum needed for a computer’s sound card, an equalizer, or a video camera. Phonographs use tiny needles reading grooves on records. Guitar pickups are simply passive electromagnets, and microphones produce their signals by way of tiny vibrating diaphragms. Line level indicates the strength of an audio signal as it passes from component to component in a signal chain. It’s much too quiet to be recorded or heard in any significant way, so what a preamp does is boost low-output signals up to line level. The initial signal generated by a microphone or the pickups in a guitar is low-output. They can be fairly pristine sounding or have a lot of character for colorful recordings. If you’ve ever plugged a microphone into an audio interface, or an electric guitar or bass into an amplifier, then you’ve already used one. What is a preamp?Ī preamp is an important part of the signal path for microphones and certain instruments, like the electric guitar. In this article, we’ll take a look at exactly what a preamp does and whether or not you actually need one. Most audio interfaces, equalizers, and mixers include some sort of built-in preamp, which does the job of most preamps you would purchase separately.

While a preamp is essential for anyone who wants to get full use out of their electric guitar, microphone, or even phono turntable, chances are you may already have one. “Preamp,” short for “preamplifier,” can be a nebulous term, whether your goal is recording/production or live performance.
