Today, we’ll be reviewing the PreSonus AudioBox iOne audio interface. There’s a lot of competition in this price range, but the PreSonus seems to hold its own. Let’s take a closer look at what it has to offer.

Our verdict on the AudioBox iOne
While there isn’t anything wrong with the iOne, it isn’t the best interface in its price bracket.
Folks on a budget may benefit from having one of these by their side until they’re ready to upgrade, but that’s the best we can say.
Check availability and price: SweetwaterAmazonI/O and controls
The unit has an XLR input, a 1/4″ TRS instrument input, and a 1/4″ headphone output, all of which are located on the front panel. Both inputs have their own designated gain controls and 48 V phantom power for the XLR.

The gain controls are accompanied by small LED lights which flash red when clipping is present. To our dismay, the instrument input has no way to switch to line level.
The device also has a button to engage direct monitoring, a master control, and a headphone volume control.

Turning around to the rear panel, you’ll find two USB ports, a Kensington security slot, and well as two balanced TRS outputs.
Recording quality
The iOne offers an A/D resolution of 24-bit/96 kHz. This is standard for professional recording.
It offers a dynamic range of 105 db, which is rather common for budget-priced interfaces similar to this.
Preamps
The XLR input features PreSonus’s Class-A preamp, which has a fairly flat frequency response.
Unfortunately, there is a 3 dB drop-off around 20 Hz, although this isn’t the worst thing in the world.
The preamps are transparent, and hold their own against most other interfaces in this price range.
At home studio
The iOne is great for beginners, as well as artists with small bedroom studios. It’s rather unimposing, and can accommodate most setups.
Mobile recording
Thankfully, the unit is bus-powered, so you won’t have to worry about forgetting any external power sources.
Its small size is great for travel, making this an ideal interface for recording demos on the road.
Build quality
Overall, the build is respectable. The unit is wrapped in a durable aluminum casing, and can take a couple of drops to the floor.
The knobs are a little bit wiggly, and the buttons feel a bit hollow, but this shouldn’t pose any serious issues.
Software bundle
The AudioBox iOne comes with PreSonus Studio One Artist and the Capture Duo iPad app. That has you covered for DAWs on both platforms.
One of the cool things about the Capture Duo app is that you can wirelessly transfer a session over to Studio One Artist on your computer.
It also comes with a very nice plugin suite that includes emulations of vintage effects and instruments.
Those plugins are all available in VST, AAX, and AU formats, so you can use them in any popular DAW.
