PreSonus AudioBox iOne Review

Layout and Controls

The iOne comes with an XLR microphone and ¼ inch instrument input with corresponding gain knobs.

In the center is a button to toggle phantom power and another to enable direct monitoring.

Next, you’ll find a large main output volume knob followed by a headphone input and headphone volume knob.

On the back is a USB-B connector and USB input that’s useful for connecting iPads.

There are also two ¼ inch outputs for studio monitors.

Build Quality 

Grade: A

The iOne, at around 1.35 lbs, is the perfect mobile interface. 

Overall, we’re impressed with its how durable it feels.

It’s housed in a quality metal casing with recessed knobs to protect against damage.

This design takes the stress out of traveling with your interface. 

You can throw it in a bag and carry it wherever you go without worrying about broken knobs.

Design Quality 

Grade: B

The iOne has a clean design, making it easy to use. 

It’s an excellent alternative to the AudioBox 96 if you want a more user-friendly interface.

Some common criticism of the AudioBox 96 is that its front panel feels cluttered and has small knobs. 

However, the iOne address has a simplified layout and a large volume knob.

It would be nice to see recording level meters or indicators to monitor clipping. 

Recording Quality 

Grade: B

This interface has high-resolution 24-bit, 96 kHz audio converters and a mic input with a dynamic range of around 100 dB.

100 dB is a solid dynamic range on par with the M-Audio AIR 192 | 4 and the Behringer UMC202HD.


Grade: B+

The AudioBox iOne features PreSonus’ Class-A mic preamps. 

It offers a solid amount of headroom and relatively low distortion.

However, the similarly priced M-Audio M-Track Solo’s preamp has a lower equivalent noise measurement (less preamp noise). Its lower makes it a better option for dynamic mics.

Grade: B

The iOne comes with all the essential features to record high-quality audio.

It doesn’t have advanced features, as is the case for other interfaces under $100.

Notable features that come with this interface are direct monitoring, phantom power, and mobile compatibility.

Software Bundle

Grade: B

The iOne comes with access to Studio One Artist and 20 Native Effects plug-ins.

Studio One Artist is a DAW that makes it possible to get started recording and producing on a budget.

Audio Interface Comparison

PreSonus AudioBox iOne vs AudioBox iTwo

The main difference between these units is the iTwo has line-level inputs.

With the iOne, the first channel is a mic input, and the second is an instrument input.

Conveniently, the iTwo offers more flexibility with combo inputs. 

Since the iTwo has line inputs, you can connect a mic preamp or other line-level device.

Also, its additional mic input lets you can record two mics simultaneously. 

Generally, we recommend the iOne for mobile recording and the iTwo for home recording.
