RME Digiface AES

Digiface AES is a professional USB 2.0 bus-powered audio interface that offers 14 input channels and 16 output channels.

It includes 2 universal input channels for microphones/line and 4 analogue output channels (2 XLR, 1 TRS jack for headphones), completing its digital I/O section.

With an excellent range of digital connectivity options, SteadyClock FS technology, standalone operation capability, and an integrated parametric equaliser, the Digiface AES is the perfect all-in-one solution for recording and playback of both digital and analogue sources, also providing flexible playback and monitoring options through TotalMix FX.
