COMPATIBILITY:

iD4 supports the following operating systems:

macOS 10.7.5 and later
Windows 7 and later
iOS 6 and later

* To use iD4 with an iOS device a camera adapter kit and a powered USB 2.0 hub is required.

POWER SUPPLY:

USB2.0 Powered (2.5 Watts Maximum)*

* iD4 features our class leading converters and class-A mic pre. We've optimised all circuitry so that we can supply true 48v phantom power to a single Audient mic pre without compromise. Your microphones will thank you when they get enough voltage.
