ESI AUDIO U24 XL - USB audio interface

Tax included

A simple USB audio interface to use. It is self powered by USB and has two channel inputs and outputs as analog. Digital inputs and outputs work at the same time with optical (Toslink) and coaxial (RCA) connectors.

Thanks to the analog connections ESI U24 XL can be used for 2ch measurements with UMIK-1 or EARS headphone jig. EARS is adviced to be used for measuring delays in car audio.

ASIO4ALL drivers are required for 2ch measuring and there is discussion about it at support forum of miniDSP.
