Inputs/Outputs:2 x MADI I/O, optical and coaxial (BNC) MIDI input and output: via virtual MIDI port Clock modes: master (internal) and slave (MADI input) Sample rates: 44.1, 48, 88.2, 96, 176.4, 192 kHz, variable (Sync/DDS) Jitter: < 1 ns, internal and all inputs Jitter sensitivity: PLL operates even at 100 ns Jitter Seamless Redundancy operation with both inputs TotalMix: 2048 channel mixer with 48-bit internal resolution TotalMix: latency-free submixes and perfect ASIO Direct Monitoring Interface: USB 2.0, bus-powered Comes with DIGICheck, RME's ultimate measurement, analysis and test tool A perfect companion Mixer, router, format converter, stream splitter, signal repeater - the MADIface USB is a perfect addition to any MADI system. Clock sources can be selected via MADI, AES or Word Clock. You can use it to create redundancy, for automatic failover, and even for creating mixes with extremely low latency between the optical, coaxial and USB 2.0 audio inputs altogether! The MADIface USB can be easily integrated into a broad range of applications. MADI portability at its best! The compact MADIface USB provides MADI I/O over USB 2.0 while supporting the format's full 64 channels for recording and playback, under Mac and Windows. Both inputs can be used for full redundancy operation. Optionally both MADI I/Os can be operated simultaneously for full 128 channel input and output access, mixed and routed by TotalMix. Even without computer the small box delivers extraordinary bi-directional format converter and active repeater functionality. Its sturdy and bus-powered design makes it as easy to use as reliable in operation. MADIface USB is both MADI portability at its best as also a perfect desktop solution to connect MADI equipment to any Mac and PC. A real gem in flexibility, usefullness and trouble-free operation - as you expect it from RME. Features and Operation Modes MADIface USB offers several operation modes when used with a Mac or Windows computer: 64 Channel Mix, Redundancy mode, 128 Channel Mix and a straight routing mode. The option Disable TotalMix completely disables TotalMix, the unit's flexible internal mixer and routing matrix. All input and output data is going straight to record/coming from playback, with no mixing or routing involved. In this mode the outputs are mirrored, carrying the same signal. In 64 Channel Mix mode TotalMix shows 64 input, playback and output channels. All settings in TotalMix use the data from one MADI input port, and send identical data to both MADI output ports. The currently active MADI input port can be configured in the Settings dialog. The option AutoSelect activates an automatic input selection. Using both inputs at the same time, AutoSelect puts the device into Seamless Redundancy mode. The MADIface USB will switch to the other input in real-time if the current one fails. In 128 Channel Mix mode record and playback is still limited to 64 channels, with the current input selected in the Settings dialog. But the other input is also available through TotalMix, and the output signal is not mirrored, but separated, with TotalMix having 128 output channels. Applications like independent mix output, monitoring and serial pass-through of the second source are just a few clicks away. SteadyClock as well as RME's well known MADI compatibility ensure hassle-free operation with other devices. MIDI over MADI technology may be used to remote-control other MADI devices. DIGICheck, an included complete audio analyzing suite, supports the user under Mac OS X and Windows. DIGICheck - Test, Measurement and Analysis Tool for Mac & Windows The Interface comes with RME's unique software tool box 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 hardware level right through to sophisticated multi-channel level meter. On Windows, an additional multi-track recorder and the display of playback data from an audio software are also available.
