What is a Preamp and What Does It Do?
Although they sound intimidating, microphone preamps technically have one main job: taking the output of a microphone and amplifying it to line-level output. In other words, microphone preamps will help boost the mic signal to a level that can be used and amplified by the rest of your studio equipment to help your vocal recording or overall recording quality produce a better sound.
For this reason, you often don’t find a microphone directly connected to a speaker since the signal will be too weak. The preamp’s job is to boost the signal to a line level that is loud enough for audio production.
How Do I Know If I Need a Preamp?
Microphone preamps are arguably one of the most overlooked and misunderstood recording equipment when it comes to completing a studio. Perhaps it’s the price of technicalities of preamps but allow us to further shed light on this matter.
If you find that your microphone has a low output and signal, then you might need a preamp to help boost its gain and line level. By doing so, you can make your mic level louder without adding much noise, distortion, and tonal coloration. As a result, you can get an audio recording that’s cleaner with a more accurate signal and headroom.
You will also need a preamp if you want your recording to sound more transparent or natural. This equipment will help in making an audio sound quieter as it can lessen the hiss and background noise caused by any signal disruptions from the microphone or instrument.
A preamp will also help in adding more warmth, color, and texture to your recordings. Preamps with transformers and discrete amplifiers in their circuits are great at churning out such results. Consider also looking at tube preamps if you want a vintage sound.
Versatility is also one function that a preamp can offer. Due to its channel strips, inputs, and outputs, a preamp can give a wide range of configurations for vocals, voice-overs, and instruments all in one device.
Lastly, if you are looking for consistency in your recordings, then you will need a preamp. By knowing the features, functions, and characteristics of the preamp, you can set how you would like the quality of your recordings to sound each time.
Frequently Asked Questions
What are the best preamps for vocals?
Aside from the preamps stated in this guide such as the Universal Audio 71- Twin-Finity and the Grade Design m101, some of the best mic preamps for vocals are the Neve 1073 DPX and the Great River ME-1NV.
The Neve 1073 DPX is a preamp with dual channels that has a high impedance, a switchable channel located in the front panel, and a built-in EQ and high pass filter. It’s also useful for vocal recordings because of its direct headphones monitoring feature.
On the other hand, the Great River ME-1NV can handle low frequencies, has adjustable gain stages, and multiple in and out connections. All of which is useful for when you want to record vocals.
Of course, to get the most out of your vocal recordings, a preamp must be paired with the best microphone for vocals so be sure to also check out our guide on that!
The answer to this question will rely on preference and requirement in terms of tonal differences. A tube preamp will give you a warm and smooth sound while a solid-state preamp will give you a crisp sound with a bite.

Most microphone preamps are 48-V phantom powered.
A channel strip is a combination of various signal processing tools including a preamp. In one strip, you will find a compressor, a de-esser, an enhancer/exciter, and for some models an EQ compressor.
Final Note
With different preamps available in the market, it can get quite intimidating to choose which is the best one for your home recording studio and audio requirements. Generally, what you will need to keep in mind are the features, desired sound character, channels, and input you will be requiring for your preamp so you can get the most out of it!
