I was very curious about this interface, so I wanted to give it a try, unless it's a Behringer with a very low price for a 8-channel AD interface. I spent two days to get the drivers working (Windows 7 64bit). The drivers on the website didn't work and after adiscussion with the Behringer helpdesk they offered me an (beta?) 3.34 version. Which worked (after trying again for a few hours). On my laptop (also W7 64 bit), the new driver didn't work, however, the most ancient version did (!). The sound of the interface is very good, also the dynamics and without any audible noise. But during a two-track recording suddenly the connection fell off between interface and computer, which stopped the recording suddenly. I am sure this was because of the drivers. After an endurance test of two days in which the interface was switched on constantly, the connection stopped suddenly. After that, the PC didn't 'see' the interface anymore, not even after a complete reinstall of the drivers ! The offered driver software is very bad. I failed to get the device working through ASIO4All. Unstable drivers are lethal to a recording, because a sudden breakdown isn't desirable. Therefore, So I have to send back the device unfortunately. The interface itself is fine (but rather primitive in terms of mixing, metering and routing). This quality is not enough if it has to operate without proper driver software.
