Note: This has been superseded by the Audient iD4 MKII.

This was a well-loved interface and received acclaim from users with different experience levels, including musicians, voice-over artists, home studio owners and more.

The ID4 packs Audient's class A mic preamp and JFET DI circuit into a compact and lightweight metal enclosure.

It is designed to be class-compliant, so it works with the iPad and other iOS devices, just as it does with Mac and Windows-based computers.

Since this unit is bus-powered, you'll need a powered USB Hub to get it working with the iPad. Thankfully, this slight inconvenience is minor compared to the benefits of utilizing Audient quality recordings on the go.

Other features include zero-latency monitoring, mix and pan controls, 2 separate headphone outputs, and a console-like interface.

The Audient ID4 MkI is also great portable audio interface for those who want to take advantage of the iPad's mobility, without compromising sound quality.
