Guide to Audio Interfaces with PreSonus

Audio interfaces turn your computer into a studio. Whether you're podcasting, recording instruments, producing music, or streaming online, they are an essential piece of kit. This guide will show you why, and help you find the perfect PreSonus interface for you.

A Guide to Audio Interfaces with PreSonus

By Daniel Collins | Published 10.11.20

Computers are incredibly powerful tools, but on their own, they're not quite geared-up for making music. An audio interface unlocks the full potential of your computer by allowing you to connect microphones, instruments, monitors, and other essential studio equipment.

At the advent of digital recording in 1975, music production required a serious studio with expensive equipment and a pro engineer - but technology has moved on greatly since then.

Since 1995 PreSonus has paved the way for home recordists and artists, freeing them from the need to hire a pro studio. With a PreSonus interface and your computer, you can get truly professional results at home and in your own studio - from capturing intial ideas to working on a complete project.

Here’s our guide on how to find the perfect audio interface.

How important is an interface?

If you want to capture audio, perform, podcast, or produce music with your computer - an audio interface is essential! 

In its simplest form, an interface acts as the bridge between the computer and your microphones, monitors, instruments, and other studio gear. The interface essentially turns your computer into a fully-fledged recording studio.

What does an interface actually do?

Audio interfaces expand the number of inputs and outputs of your computer. Depending on the device, you'll be able to connect microphones, instruments, monitors, and other studio gear.

Audio interfaces also improve the quality of your computer's sound by dealing with the analog-to-digital conversion - such as converting the analog signal of a microphone to a digital signal inside your computer.

One key benefit of an audio interface is that you could record multiple sound sources at once - perhaps a complete band, or an interview with several people. You could also route audio in more complex ways than a simple "in-out" configuration - perhaps creating a monitor mix for the control room as well as a headphone mix for a musician.

Connectivity - how will it connect to your computer?

USB – commonly available. USB is a fast and reliable connection (especially USB 3). USB interfaces are often able to operate on Bus power alone, taking power from your computer without the need for an external power source. Grab a laptop and record anywhere!

Thunderbolt – perfect for ultra low-latency recording and the highest of A/D conversion quality. Thanks to their super-fast transfer speeds, Thunderbolt interfaces are quickly becoming the new gold standard.

Inputs and Outputs

What studio gear would you like to connect to your computer?


  • Microphone – Microphone inputs consist of a female XLR socket. These allow you to connect your microphones directly to the interface via XLR cable, without the need for additional equipment. Microphone inputs feature a built-in preamp which amplifies the signal and brings out the best sound of your microphone.
  • Line-level – Line-level inputs eliminate the need for external DI (direct injection) boxes. They enable you to easily capture DI signals from your guitar, bass, keyboards and synthesisers by plugging your instrument cable straight into the interface.
  • Combi-Jack – Combi-jack inputs provide the best of both worlds, accommodating either XLR or ¼”  jack cables in the same socket. Incredibly versatile, you can use these inputs to record either microphone or line-level signals.
  • MIDI – Often situated on the rear of the device. MIDI inputs allow you to connect hardware synths, sequencers and drum machines.
  • Optical – Often featured in high-end interfaces. This “ADAT” connection point enables you to daisy chain your interface with another to expand its connectivity and provide enough power to take on any task.


  • Headphones – Headphone outputs are incredibly handy. They allow both you and the musician to monitor the master channel of your DAW in real-time whilst you’re recording, without introducing feedback or bleed from speakers. The greater the number of these outputs, the more flexibility you’ll have when determining individual headphone levels.
  • Monitor – Just like headphones, monitor outputs are a standard feature on nearly all interfaces. Most consist of ¼” outputs that are designed to directly connect to studio monitors, or to an amplifier which then feeds passive studio monitors.
  • MIDI – MIDI outputs serve to transfer data directly into the Digital Audio Workstation
  • Line Outputs – Line outputs are useful for a variety of reasons. You can use them to create individual headphone mixes, re-amp, as well as send your signal to outboard equipment and even send mixes to alternate speakers!
  • Word Clock – When you’ve mastered the basics and want to turn pro, expanding your setup, the word clock will be a lifesaver. This handy function allows you to set one piece of equipment as a “master” and the rest as “slaves” which keeps everything in sync for trouble-free recording.

Interfaces often feature a mixture of physical controls and software parameters. "Real" controls allow you to make adjustments "on-the-fly", whilst software provides remote access to parameters if you're away from your interface.

  • Gain – Like a volume control for the incoming sound source. The more gain that's applied, the more sensitivity you'll have. But don't run the gain too high, or you'll overdrive the input and create distortion.
  • Clipping Indicator – If your incoming sound source has its gain set too high, you may overdrive the input and record irreparable distortion. You may not know you've done that until after the recording has taken place. That’s why clipping indicators are incredibly valuable. If you see a red light, you'll know your gain is set too high!
  • Phantom power – Engaging phantom power supplies a positive voltage through the XLR cable which is used to power condenser microphones.
  • Phase – When you’re handling stereo/multi-mic’d sources, the phase control is incredibly important. Engaging this control flips the polarity of the channels’ signal by 180 degrees. This is commonly used when a direct and amplified signal are recorded simultaneously.  If you find your recording sounds bigger and fuller when this control is engaged, then your signal is out of phase. If pressing the phase button “thins” your signal, then it is in phase and does not need a polarity flip.
  • Filter – The filter control enables you to get the sound right at the source. When applying the filter, it automatically reduces the low-frequency content that your microphone or instrument has recorded. Applying the filter is perfect for minimising “proximity effect” which can occur when close-micing a source. The gradual roll-off also prevents the risk of “muddy” mixes. However, it’s important to check the frequency and slope of your interfaces’ filter before applying as this will differ greatly from brand to brand.
  • Pad – If a pad switch isn’t available on your microphone and you’re recording a source with a high SPL (sound pressure level) then this can be a real blessing. Depending on its specifications, engaging the pad switch on your interface can reduce the level of your preamp by up to 20dB. This decreases the risk of distortion ruining those all-important takes.
