Deciding on the recording equipment you need is quite confusing when you’re first starting out. Producing a clear, good-quality voice over for your eLearning course isn’t as complicated as you may think when you’ve got a little knowledge on your side.

Before you look into anything else, you’ll need a good voice over microphone to capture your voice. You don’t want to compromise on the quality of your mic because it will have a huge impact on the overall quality of your voice overs. Another important piece of equipment in your recording toolkit may be a preamplifier for your microphone.

What Is a Microphone Preamp?

A microphone preamp is a tool that amplifies the electrical signal emitted by your microphone and converts it to a language that’s understandable for your computer and recording software. It also works as an interface between your microphone and your computer to supply power to the mic.

Do You Need One?

In a word, YES!

Without a preamp, the quality of your recordings may be compromised to a significant extent. Conventional microphones have an output standard too low to be plugged into the recorder directly. A good-quality preamp will amplify the low-level signals of the microphone, ensuring louder and clearer mic signals.

That being said, most audio interfaces have a built-in preamplifier so many voice over artists don’t bother buying a preamp. However, if you’re recording voice overs for your eLearning course, you would want the quality to be as good as possible. Therefore, buying a preamplifier for your microphone is a good investment.

I’ve got one even though my audio interface also has one. Having a stand-alone microphone preamplifier results in better sound. The nice thing is, most of this equipment only requires one-time investment and it’ll last for years.

I’ll go through the best microphone preamps for you next, including the one I’ve got …

Best Microphone Preamps for Voice Overs

When it comes to music producers and recorders, they often look for brightly colored and stylish preamps. In the voice over world, that’s really not something you’ll care about. Go with quality and efficiency over color and excitement.

Because I realize keeping within a budget is important, the list starts out with the lower end mic preamps and ends up at the more expensive preamps.

Efficient Mic Preamps

The following are the most popular and efficient preamps that fall into the affordable category …

1. ART Tube MP Studio Mic Preamp

ART Tube MP Studio Mic PreampThis is the one I use and yep, I admit it, at $59, the microphone preamplifier I use is the cheapest one on this list.

At the time I just didn’t understand why I even needed one of these. I get it now and wish I would have invested in something a little more robust. Even with the low price, I think my recordings sound pretty good. I had been using much less expensive equipment (I had the all-time cheapest equipment when I started out) so what I’ve got now is much better.

This piece is easy to use. I like to plug everything in and then just go so this works for me. It works great with microphones and for a very inexpensive price, will add some warmth to your voice overs.


  • Inexpensive, but still helps give your voice a boost.
  • Smooth and warm sound quality.
  • Provides over 70dB of gain.


  • Have to plug it in and out each time you use it because there’s no power button.
  • It’s not going to get you as much of a noticeable difference as some of the more expensive mic preamps.
