It’s time to start laying down those tracks so you can wow the world with your musical prowess, and the talent that started out with just a teeny tiny bud of a desire to play, all those years ago.

Is A Mic Preamp A Must-Have?

As you’re planning everything out, you might be thinking about what you absolutely must have in your studio.

One of the items on that list really ought to be a microphone preamplifier. But what do they do? And better yet – how do you figure out which one you ought to bring home?

How do you determine what the best mic preamp is?

Here’s a handy guide to some of the best preamps we’ve found on the market, and how this technology can improve your studio sound and recordings.

What Does a Mic Preamp Do?

A “preamp” refers to one of two things: either the internal preamp circuit within an amplifying device (like a microphone), or a dedicated external device that does the same thing. There are two types of mic preamps: onboard (built in panel) and outboard (dedicated external).

Your mic is a powerful tool, but microphone signals are generally way below operating level, which means you need to add a preamp for external gain in order to raise the signal and avoid harmonic distortion.

Typical Gains Are Too Low For Quality Audio

A vocal gain is typically 30-60 dB, while instruments like the acoustic guitar or bass might only require 20-30dB of gain. You may think your sound is loud enough, but consider this: your standard home studio kit has a standard nominal level of +4dBu, while electronic instruments have an output around -10 dBv.

So, in order for your one-of-a-kind, super unique sound to be heard, you’ll need a preamp. While many audio interfaces have built-in preamps, and this may be good enough for most users to get started, you’ll want to improve your technology with a dedicated preamp to get that serious sound on your marketable recordings.

What Are the Benefits of a Preamp?

In addition to making sure you can be heard, with clean, crisp sound, preamps also offer a lot of additional benefits to the overall quality of your sound.

• A mic preamp can offer better sound quality.
• An external preamp allows more gain.
• You’ll experience lower studio noise.
• You’ll gain a richer sound character.

When a preamp is not used, it’s possible that users will find their sound quality changing as the gains increase, especially with a lower output microphone. If you’re just starting out, it’s likely that you won’t have the best microphone on the market, and sound above 40-50 dB might start sounding a little blurry.

That’s probably not going to help you sell your single and get you that gold record, so it’s time to clean things up with preamps.

Increased Gain Helps To Lower Noise

A preamp will be capable of giving you more gain, and best of all, with lower noise. If you use low output, ribbon mics, or need to record quieter voices and instruments, you’re going to want to eliminate any internal and external noise.

And as it turns out, an outboard preamp is less noisy than an internal preamp.

Tube Preamps Have An Awesome Vintage Sound

The ‘sound character’ is probably something you’ve already heard about.

A lot of musicians love the unique vintage sound you can get from external preamps. While each type of mic is known for its distinctive “voice,” preamps are actually very similar.

Some even include controls such as phase reverse, low cut, and pad switches.

Some Preamp Sounds Are Actually ‘Signature’ All On Their Own

In fact, you might have heard of some performers using preamps for live shows, to capture that signature sound.

For those who are just starting to perform live and in the studio, know this: A road preamp is going to be one more piece of equipment you’re going to have to explain to your roadies and sound crew, so you might want to hold off until you hit the arenas, and invest in a preamp for the road.

But in the studio, a mic preamp is actually an essential.

How Do I Choose the Best Preamp for My Music?

Unfortunately, there’s no such thing as a universal preamp. Not only are there different styles of preamps, but each one will function a bit differently.

Some are best at capturing spoken performances, such as podcasts and livestreams, while other preamps are fantastic when paired with musical instruments.

Consider Your Budget

First, you’ll want to check your bank account.

Much as Bill and Ted argued over whether Eddie Van Halen would make the Wyld Stallyns, or whether having a clutch band would attract Eddie Van Halen, you may be mulling over the same type of puzzle.

If you buy the fantastic equipment, then your recordings will be phenomenal. But if you haven’t sold the albums, then how can you afford the equipment?

Therefore, beginning professionals ought to pay attention to price point. In this post, we’ll take a look at mic preamps from a variety of price ranges, so you can decide on the very best option for your wallet.

Consider The Number Of Channels

Next, consider how many channels you’ll need. While most mic preamps include one channel, meaning you can use one microphone at a time, you can find preamps with eight or more channels.

So, ask yourself: will you use more than one mic at a time? Depending on how many instruments and voices you’ll have harmonizing at a time, 2-4 channels might be a good investment to start.

Alternately, you might need multiple preamps for more than one mic.

What Type Of Preamp Should You Invest In?

Then there’s the type of preamp. The most popular types of preamps are tube, solid state, or hybrid. Vacuum tubes are typically associated with harmonious sounds, while solid-state preamps have a very clean type of sound, which many feel has a “digital” feel.

Hybrids offer both of these benefits, but they often have a higher price tag.

Consider What You Are Trying To Interface With

Inputs and outputs are also important.

Having a preamp on hand doesn’t help if it can’t communicate with your mic and other equipment.

Make sure you add the preamp into your overall map of equipment, so you know exactly what you need to make sure it works.

One look at this preamp, and it’s easy to tell the difference between it and the others listed above. It doesn’t even seem to compare. First, you’ll notice that it has a lot of controls.

The Avalon 737sp preamp offers three inputs: a high performance mic input transformer with +48v phantom selection, an instrument DI high source input jack located on the front panel, and a balanced line input discrete high-level Class A rating.

In Summary

While we can definitively say what we think the the penultimate preamp amongst all of the preamps on the market is, there are still a lot of wildcard factors at play. First, there’s your mic. If you have a low-quality mic, not even the most exclusive luxury preamp in the world can save you.

You’ll also want to make sure your studio or recording space is set up correctly, from an audio standpoint. You don’t want your preamp rattling against walls or shelving, and you definitely don’t need your mic picking up on your neighbors arguing… unless that’s the kind of recording you’re hoping to sell!

You May Need More Than One Preamp

You may need multiple preamps, if you’ll have more than one mic at a time, which is typical of most studios.

While preamps are great at magnifying sound, most of the models we’ve rated today only offer one channel. Bear this in mind when making your ultimate selection.

Pay Close Attention To The Features!

Preamps also offer a significant variety of functions and capabilities.

Compare the budget preamp to the Avalon, and you’ll see a huge difference in the number of features. Before selecting preamps, consider how much control you want (or need) to create your ideal sound.

In Conclusion

There are plenty of preamps on the market, but as we’ve discovered today, not each preamp is created equally.

As you research preamps, bear in mind all the functionality you need, and how this model will fit into your budget, your studio, and your future plans.

But at the end of the day, the most important thing is to make your choice, order your preamp, and get back to doing what you do best… creating awesome audio and vocals for your projects!

That’s what it’s all about! That is, by far, the most important part of all of this!

So keep on creating!

We’ll see you on the next one.
