Understanding a Mic Preamp

A Mic Preamp, full name microphone preamplifier, is a device used in sound engineering and recording to capture and process high-quality sound signals. These could be vocal sounds or sounds from instruments like guitars and drums.

A microphone as you know it, on its own, without any additional devices has a low output voltage or signal, usually around 30-60 dB. This signal strength is way below the standard operating levels for recording purposes.

What a Mic Preamp essentially does is to take the signal that comes from a microphone and boost it for processing by other devices like an audio mixer or speakers. Most preamps can boost sound signals by up to 70 dB.

Generally, a mic preamp can exist in two types, one type is a preamplifier circuit that is integrated into a sound recording device and the other is a dedicated external device containing the same circuits.

In this guide we will review the dedicated external mic preamp, in the simplest of terms, this is the device that you plug your mic into before relaying to the audio mixing device.

So What Exactly Do You Gain from Using Mic Preamps?

  • Better sound quality
  • More gain
  • Lower noise
  • Special sound character, for example, you can make the sound smooth, dirty, vintage etc.

Things To Consider When Buying a Microphone Preamp

Most people focus on the price when buying a mic preamp, this is ok, especially if the product fulfills its basic purpose of boosting a low-level signal up to line level.

But there are other things that you should consider to get the best mic preamp that suits your objectives at cost-effective prices.

It is also important to keep in mind that an external preamp has to be linked to the rest of the studio equipment and as such, you should consider the different ways that the rest of your equipment will connect to the preamp.

With that said, here are some important things to consider when buying a microphone preamp:

Inputs and Outputs

It goes without saying that you need to connect a microphone to a preamp and be able to connect the preamp itself to the rest of your gear. In this regard, any mic preamp will have at the very minimum, one input, and output connecting channel.

The input to connect to your sound source and the output to connect to the audio interface or mixer. This enough for most basic users but some people need more functionality from the preamp. If this is the case you can look for a preamp that has a hi-Z direct signal input, this allows you to connect other musical instruments like a guitar and other electrical instruments.

If you intend to connect the preamp to multiple output devices, then you will need to purchase a mic preamp with multiple output channels.

Unique, Duo or Multiple Channel Preamp

One very important thing you have to ask yourself before buying a preamp is how many microphones will you be using to record at a given time. Will you be using just one microphone at a time or you will be using multiple microphones simultaneously?

There are preamps with a unique microphone channel, dual channels, and multiple channels. The pricing differs for each type with the multiple channel system priced higher than the rest. Depending on your needs currently and in the future, you may find the multiple channels to be cost-effective even though it is priced slightly higher than the rest.

Always keep in mind that even though you may not be recording with multiple mics simultaneously at the moment but that can easily change in the future as your project grows and develops.

The Tube Saturation Preamp or the Solid State Preamp

You have to consider your intended sound sonic signatures when buying a preamp. Sonic signatures define the “character” of your sound.

To make it simple, a tube saturation microphone preamp will give your recording a lush-like euphonic sound while a solid state microphone preamp will add crispness and clarity to the recorded sound. Only you can decide which character you want for your recordings.

TIP: There are hybrid preamps that contain both tube saturation and solid state circuit at a slightly high price.

Form

The form factor will depend on how your recording studio is configured but there are basically three form packages: the standard 19’’ rack mount, the 500 series module and the desktop unit. Some preamps are available in multiple form factors.

Additional Features to Consider

Other features to consider basically depend on your needs. Depending on your objectives you can consider features like low-cut filter, switchable transformer, stereo recording and balancing etc.
