Best Microphone Pre Amp Buying Guide

What is a mic pre amp?

In case you didn’t already know, a microphone preamp is an electronic device that is used for sound engineering. You can use them for various things such as in recording or home studios, in concerts and shows to mix live output, radio and news broadcasts, in TV or by musicians that want to make a bigger, more clear sound.

The preamp essentially prepares signals from a microphone in such a way that it as able to be processed when you use sound engineering gear. The preamp boosts the signal and clarifies the sound. It also projects a number of individual layers of output to make sure that it is possible to hear them in the overall mix. It aids in minimizing the amount of hum, hiss and noise. 

With a mic preamp you are able to manipulate sound as necessary. Of course, some products have more manipulation available than others.

Choosing the Right Pre amp

There are a number of considerations that you should make when you are trying to purchase a mic preamp. Different things like durability, quality and price are all considerations, but there are also some others that you may not have already considered.

Channels

One of the most important things to consider is how many channels the preamp has. Some of the most popular microphone preamps only come with a single channel that you can use for one microphone at a time. Others can come with 2 channels, 4, 8 and some come with even more than that.

In a nutshell, you will need one preamp for every mic you intend to use at one time. If you are performing live with a huge band and you have to pick up a number of dynamic mics you are going to need a lot of channels. You may not need that many though if you are recording in a studio with minimal instruments and microphones, as this is something you will be able to do separately. 

Types of Pre amp

There are a few different types of preamp on the market and they all differ in some way. Some of the most popular and indeed, some of the best quality audio originates from a solid state, tube or a hybrid type design.

All of these preamps carry their own unique sound. A tube will give you a warm and harmonious sound, solid states on the other hand sound more digital, with a very clear and crisp sound. Hybrids have both of these qualities, though they can cost a little bit more money. 

Price

Of course price is going to be a big factor. They can get pretty expensive. There are so many options on the market and so if you are on a budget you either need to save for a bit longer or you need to assess what features are deal breakers for you. Some preamps can be quite inexpensive whereas others can be upwards of a thousand dollars. 

Transparency and Coloration

A lot of audio interfaces today tend to have preamps built in and a lot of them are more on the transparency side. This is all well and good but you may desire more than this. A lot of Solid State Mic Preamps are designed to give you even more quality, and provide more control over the sound that you get. 

If you are looking for something with a warmer sound with coloration, it’s worth opting for a Tube Preamp as this tends to replicate that old style of audio recording. It’s worth considering what kind of sound you want to achieve before you buy your preamp and then purchase something that will give you the best sound for your music. 

Should you get a transformer?

This is a widely debated topic when it comes to mic preamps. To put it into technical terms, a transformer is used in audio circuits for a range of different purposes. Some of these purposes include decreasing or increasing signal voltage or the impedance of a circuit.

To put it more simply though, a transformer gives a little bit more character to a sound. A lot of audiophiles refer to this as a ‘warm vintage’ kind of sound. These make a more transparent and uncolored sound. Of course, whether you get a transformer depends on what sound you want.

With that being said, some mic preamps actually let you switch the transformer in or out, which means you can make the decision about whether you would like to record using a colored sound or with a sound that’s a little more transparent and clear.

Source of Sound

The whole purpose of a mic preamp is to give more quality to a vocal recording but some of them work very well at adding a better sound to instruments too. Usually transparent preamps have a little more versatility, and vintage voiced versions have more limitations but they work well when you are trying to mimic old school recording styles.

Quality Matters

When you have extra amplification, it’s very important that the mic pre amp you get is made and built with good quality. Badly made and cheap models aren’t going to give a very full sound and are likely to sound quite poor as a whole, with a great deal of noise.

It’s worth considering how the device is constructed and what it includes because the chances are if you cut on price and you get hundreds of features for an obscenely low cost, the quality will have been cut somewhere.

Inputs

The majority use normal XLR jacks so that they can be connected to professional microphones. If this is not the case, they tend to have a line level ¼ “ input that allows you to connect instruments such as bass and guitar.

This kind of input is usually referred to as a direct input. These kind of jacks will allow you to be able to record straight into your DAW so they are particularly helpful for modern track production. 

You may also find a DSub connector on multi channel mic preamps, and this allows you to be able to join together a number of channels to the device by using a snake or breakout cable such as a  D-Sub to XLR or D-Sub to ¼” snake.

Outputs

The majority of professional audio interfaces will use a normal XLR jack for every mic pre channel, but if yours doesn’t you may instead find ¼” TRS jacks. Some of them even have both. On multi channel mic preamps you may also have a D Sub connector so you can connect a number of channels to your device by using a snake or a breakout cable.

Additional Features

There are a couple of extra features that are worth considering too. Some things you should look for include phantom power, an input pad and some practical features such as EQ or high pass/low pass filters. You could also consider a noise gate and a power switch too.

Channel Strips

Channel strips are essentially a microphone preamp that is then combined with other signal processing circuitry in the same area. Some very common additions are things such as EQ and compression/limiting. Some other features such as a de esser or an aural excited are also sometimes added. 

Channel strips are made to give you all that you could possibly need to be able to record, all in one place. It means you don’t need to buy any more patching cables too so you save a little money. It can be quite affordable, especially if you plan on recording from a home studio. 

General Guidance

So what mic preamp you choose can largely depend on the sound you want to achieve, so there are some guidelines worth considering.

To start with, if you have quite a thin sounding instrument or vocalist, then having a tube mic pre amp means that you are able to bulk the sound up a little. You can also get a lot of warmth with a tube pre amp when you use it with an acoustic guitar for example, though many sound technicians tend to prefer the natural sound instead, which can be better achieved with a solid state preamp.

With drums, you can get a thicker sound by using a tube mic pre amp as this will compress the sound. With solid state the attack sounds will be more prominent.

Finally if you are doing a classical music recording, a solid state pre amp may be better for a purer sound.
