The ESI U24 XL continues the tradition of offering extremely small and portable audio devices that are excellent high quality. With the legacy of our famous Waveterminal U24 in mind, U24 XL has been released just in time for the 10th anniversary of ESI product sales. U24 XL is not only stylish, but with dimensions of around 10 cm x 9 cm it is a device that can go with you anywhere.

Offering total flexibility of an external USB device and pure digital quality, coupled with true high quality 24-bit support on the 2 analog input and 2 analog output channels provided via TRS connectors, U24 XL will easily qualify as the most useful device in your studio, wherever that may be. Even better, U24 XL also provides digital S/PDIF connections in both optical and coaxial format. U24 XL ships with Cubase LE 4.0 from Steinberg for both Mac and PC. If you are looking for a really powerful USB audio device that is small and that gives you maximum performance under Mac OS X as well as under any current Windows environment including Windows Vista, then U24 XL is for you.
