Synthax Announces New RME Digiface USB Portable Digital Audio Interface

Compact form factor and bus-powered operation facilitates anywhere operational ease

Ft. Lauderdale, FL – February 2017… Synthax, Inc., the Americas distributor for RME, a leading manufacturer of high quality digital audio solutions, is pleased to announce the RME Digiface USB Portable Digital Audio Interface. Featuring 4 optical ADAT /SPDIF inputs and outputs plus a high-quality analog line/phones output via TRS (tip-ring-sleeve), the new RME Digiface USB is an extremely compact, portable digital audio interface that can also serve as a basic headphone amp for mobile use.

The new RME Digiface USB simplifies the connection with USB 2 devices such as Mac and PC computers. Utilizing bus-powered operation, it does not require an external power supply—making it ideal for portable use. Further, the Digiface USB adds another optical I/O, resulting in 32 channels of input and output when using the ADAT optical interface. The analog output hosts channels 33 and 34, and can be used freely in conjunction with RME’s included TotalMix FX real-time digital mixing software—resulting in a highly capable routing and monitoring solution.

Each single optical port on the Digiface USB can use either ADAT optical (up to 8 channels) or S/PDIF (stereo). While the inputs adapt automatically to the incoming signal format, the outputs can be individually switched between ADAT and S/PDIF operation—resulting in exceptional flexibility. Equally notable, the Digiface USB supports both SMUX and SMUX4, which is used to transmit high bandwidth digital audio using lower bandwidth technology. Hence, with this capability, an 8-channel audio stream at 192 kHz audio can be accommodated via 4 x S/PDIF or ADAT on both the inputs and outputs.

Mathias von Heydekampf, Managing Director at Synthax, commented on the new Digiface USB Portable Digital Audio Interface. “RME’s new Digiface USB is an extremely versatile interface that delivers exceptional audio performance. Featuring both multi-ADAT I/O and multi-S/PDIF I/O capability, the Digiface USB is a comprehensive solution with the most flexible routing and monitoring options available in its class. This interface runs on RME’s MADIface series driver, shares ASIO with several other RME devices, and offers stable operation with the lowest latency for 32 samples with all channels in use. With its compact size and rich feature set, I’m confident this interface will be very popular with a wide range of musicians and audio pros.”

The RME Digiface USB Portable Digital Audio Interface is available now. MSRP pricing is: $599.00.
