iRig Pro I/O: first look at IK’s latest cross platform audio interface

IK Multimedia has added 3.5 mm monitoring to its original iRig Pro I/O cross platform audio interface.

Today IK Multimedia launched its latest cross platform audio interface, the <US$150 iRig Pro I/O. An apparent successor to the original iRig Pro (which I reviewed in 2014), the new iRig Pro I/O adds a 3.5 mm TRS output for headphone monitoring, as well as optional simultaneous charging of an iOS device. However, the iRig Pro I/O is fortunately not limited to iOS. When I say “multi-platform”, I mean direct connection for Apple’s Lightning connector (used on all current iOS devices, including the iPhone/iPad/iPad Touch) and USB for Android, Chromebook, Mac and Windows devices. I just received a review unit, and I am preparing a detailed comparison to its closest competitor on the market, the <US$150 i-XLR from RØDE (which is Lightning-only), including test recordings to hear the preamp and A-to-D quality, specs and practical pros/cons. In the meantime, ahead are specs and photos.

Flexible power options

The new <US$150 iRig Pro I/O (Amazon linkB&H link) has multiple power options depending upon your recording situation. When used as a standalone interface for an iPhone, iPad or Android device, you can power iRig Pro I/O with 2 – AA batteries that also provide switchable 48V phantom power for condenser mics.

When use with iRig PSU 3A, the optional DC PSU, iRig Pro I/O will charge your iPhone/iPad/iPod Touch while plugged in for endless or extended recording and playing sessions.

When used with a Chromebook/Mac/Windows computer, iRig Pro I/O gets its power from the USB port and the connected laptop.
