The DuaFire is the world's first FireWire audio interface that perfectly supports EWDM technology.

ESI finally adopted the famous EWDM technology to a FireWire Audio interface. Now you can use driver interfaces like ASIO 2.0, GSIF 2.0, MME and WDM simultaneously with the same features that made ESI's PCI audio interfaces famous. Of course, EWDM for FireWire also provides the DirectWIRE technology the virtual digital patchbay and support for very low latency values (as low as 1.5ms or even less).

DuaFire is an ideal mobile recording interface for both laptops and desktop computers. It's flexible inputs allow you to record from a variety of different sources. You can directly connect devices with line level, turntables via the built-in phono preamp, microphones (+48V phantom power support) and Hi-Z signals (e.g. a guitar).
