Top 5 Best Best Mic Preamp Under 300 

What is a mic preamp and what does it do?

Before we go into selecting and choosing a preamp, we need to know exactly what one is and whether you need it in your home studio.

A microphone preamp is simply an equipment that enhnces and increases the audio quality of your microphone when reocrding.

Now this is the layman’s definition.

It certainly has some technical twists and turns to it which you can read all about here.

I get really upset when I see most people recording vocals without using any preamps


Simply because spending a few extra dollars to get a preamp will definitely make your vocals sound so much better.

Also because unlike other musical equipments like the guitar or keyboard which produces its own line level signal, your microphone produces its own signal by converting acoustic energy into a low voltage output.

This output can be anywhere between 50dB to 80dB quieter than most signals.

This makes it so much harder to deal with than when you get a preamp.

Here are some ways that a preamp affects your sounds

  • It makes your audio vocals sound louder
  • It helps to “color” the audio that passes through it
  • Depending on the type of preamp used, it can add some harmonic distortion to your signal

Things to consider before you buy a microphone preamp

1. What is the coloration?

This is probably the most important thing you need to consider before buy a cheap mic preamp.

Coloration simply means a type of harmonic distortion that can be very desirable for vocals.

As such you want to make sure that any preamp that you buy has some form of coloration associated with it.


This is because it enhances and brightens your audio signal as it passes through it.

Basically there are two type of mic preamps that you need to look out for when considering coloration.

  • Tube preamps
  • Solid state preamps with transformers

2. What is the form factor?

This simply has to do with the physical design of the casing that comes with it.

A good form factor will ensure that your product lasts for a very long time and survives all the wear and tear that comes withmost studio equipment

There are three choices you need to make when considering form factor

  • Desktop
  • Rackmount
  • 500 series

Whichever one you choose depends on your future plans and the type of studio gear and equipments you wish to purchase in the next 5 years.

3. How many channels does it have

Finally you want to consider the number of channels that your preamp has

The more the number of channels, the more options you have when recording

Basically you want to go for a preamp that has at least 4 channels

This will make your life so much easier and ensure that you can connect as many equipments as you need.
