RME Digiface USB 66-Channel, 192 kHz, USB Audio Interface with 8 Channels Via 4 SPDIF or ADAT

The latest plug-and-play technology in the RME Digiface USB guarantees a simple installation, even for the inexperienced user. Numerous unique features as well as RME's robust drivers enable a quick, efficient, and comfortable operation of the RME Digiface USB. Its small size, weight, and bus-powered operation make the Digiface USB extremely versatile and useful. It could even serve as a simple headphone amp for mobile use.
Compact, Portable, and Lightweight Audio Interface
The Digiface USB is an extremely compact and portable digital audio interface with 4 optical ADAT SPDIF I/Os, and an analog high-quality line or phones output via a 6.3 mm TRS jack. Continuing the legacy of RME‘s famous HDSP Digiface, a triple ADAT I/O interface with phones and PCI interface, Digiface USB simplifies connection with USB 2, does not need an external power supply, and even adds another optical I/O, resulting in 32 channels input and output each when using ADAT optical. The analog output hosts channels 33/34, and can be used freely thanks to TotalMix FX, RME‘s routing and monitoring solution that knows nearly no limits in routing and mixing the Digiface USB does not include FX. Each single optical port can use either ADAT up to 8 channels or SPDIF stereo. While the inputs adapt automatically to the received signal format, the outputs can be individually switched between ADAT and SPDIF operation. Supported are SMUX and SMUX4. Therefore at 192 kHz either 8 channels via 4 SPDIF or ADAT are possible on both inputs and outputs.
The Interface comes with RME's unique software toolbox for metering, testing, measuring, and analyzing digital audio streams. On Mac OS X provides unique functions and features of the spectral analysis of the data calculated in the hardware level right through to the sophisticated multi-channel level meter. On Windows, an additional multi-track recorder and the display of playback data from audio software are also available.

RME Audio develops its own interface core, it’s not dependent on 3rd parties for upgrades, modifications, or bug fixes, so customers can use the latest operating systems without interruption or delay.
