Top 10 Best Mic Preamps For Vocals 2020 – Buyer’s Guide

The arrival of social media has widened everything around our daily life circles. Some 5-10 years ago, nobody would have that social media will change the whole dynamics of the world economy. People are now investing in themselves in order to make a long-term and financially sustainable career. 

Video content is perhaps the most popular element when we think of producing your own content on social media. In our earlier articles, we talked about microphones and their importance in order quality content for online streaming platforms such as YouTube, Facebook, and Instagram. 

Today, we’re going a little further from microphones and would talk about something that is coming before the microphones. You must have heard about microphones and their ability to produce quality sound. 

However, a vital role is also played by Microphone ‘Preamps’ and today, we’re going to talk about the best Microphone Preamps for vocals. There are basically two ways of understanding the Preamps. 

It basically comes in two forms. Sometimes it comes as a Preamplifier circuit within the device and sometimes it comes as a dedicated external device to contain such a circuit. The main job of a Preamp is to amplify the low-level signals to line level that is considered as the standard operating level of your microphone. 

Normally, microphone signals are well below the nominal level of operation and a lot more is required, typically about 30-60 dB. Guitars and basses do not need as much gain, but mostly approximately 20-30 dB. Also, line sources such as synthesizers may demand studio-level amplification, as different specifications are available.

For home audio and semi-pro equipment, the old standard is or perhaps it was -10 dBV, whereas technical equipment is running at +4 dBu, which is not a difference of 14 DB but about 12 DB due to different voltage references. Even inexpensive home studio equipment is today usually designed to a nominal level of +4 dBu, but electronic devices also frequently operate at -10 dBV or somewhere around it.  

And for almost every sound source, you need a Preamp. Nevertheless, this must not be an external machine. Most audio interfaces come with Preamps already built-in. And they’re generally great enough, to begin with. However, it should be remembered that much more costly audio interfaces have much better Preamps than lower-ranked and cheap audio interfaces.

Forget about an external preamp if you’re just starting out. Instead, get an audio setup slightly more costly with good preamps. When you deal with low output dynamic microphones or ribbons, an outer Preamp will greatly boost the sound quality. The external preamp makes less of a difference with high-level condenser mics.

An outdoor preamp is a decent second step towards improving your sound quality or having more volume, but before you do the first step, don’t jump to the second step. With the internal preamps and one or two high-quality condenser mics, you can only make decent recordings with your audio app.

Top 7 Best microphone preamps for Vocals 

This was a little introduction about our today’s topic, and now we will move on to shed light on some of the best microphone preamps for vocals that are currently available in the market. 

Dbx 286s Stereo

As a content creator, when you start a proper streaming channel on any of the above-mentioned platforms, then you also start working on the technical aspects of your content. 

The first and topmost priority for any content creator is the video quality, for obvious reasons. However, a professional content creator with long term ambitions would also take care of the sound and audio quality as much as he does for video quality. 

We have been trying many internal and external preamps and the journey started with first generation series of 6 ux2. 

We also spent our money on the Blue Snowball before moving to Blue Yeti for quite some time. As the Yeti was getting old some time ago, we decided to enhance our audio quality even further, and then someone suggested us to take a look at the Dbx 286s stereo preamp.

The most effective and primary reason for recommending the dbx 286s is the Expander gate ability. You can see it as a highly-effective noise gate and it’s going to do a lot of hard work in canceling the background noise for you that isn’t necessary. 

Offices and home labs are full of background noises and if you’re using a good microphone, you’d perhaps enhance your audio quality to a great level. It will also cancel all the unnecessary stuff around you really effectively. 

When you change your speech volume a lot, this will be a significant feature for you. Well, the De-Esser takes that disturbing sound away if you talk about snakes that slither up a hill. The LF / HF detail of the enhancer will add more warmth and clarity to your speech, using it sparingly.

The dbx 286s is an absolute magician in this field. This is an extremely suitable device for all the people that are working in a highly noise-affected area or office. This device has the ability to completely eliminate the background noise and let you produce high-quality content with appealing audio quality.

The dbx 286 has no native device system. There is no standard computer connection such as USB, thunderbolt, etc. You can use different USB audio interface devices to connect it such as the Scarlett USB interface device. 

This is one of the top-rated devices on Amazon and it is surely capable of providing a lot of value for its money.
