Overview
iD4 delivers the audio performance of a large format console in a portable desktop package enabling you to record your vocals and guitar simultaneously. Providing one renowned Audient console mic pre, class-leading converter technology, dual headphone outputs, console style monitor control, JFET D.I and our virtual scroll wheel technology 'ScrollControl', iD4 is a professional but affordable solution for your home studio or for when you’re on the road.
Features
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.
