[. . . ] Therefore, when selecting Emphasis all analog outputs will be processed by a treble filter based on 50/15µs, which sounds like a high cut. The Fireface's new output header is optimized for largest compatibility with other digital devices: · 32 kHz, 44. 1 kHz, 48 kHz, 88. 2 kHz, 96 kHz, 176. 4 kHz, 192 kHz depending on the current sample rate · Audio use, Non-Audio · No Copyright, Copy Permitted · Format Consumer or Professional · Category General, Generation not indicated · 2-channel, No Emphasis or 50/15 µs · Aux bits Audio Use Professional AES/EBU equipment can be connected to the Fireface 800 thanks to the transformer-balanced coaxial outputs, and the `Professional' format option with doubled output voltage. Output cables should have the same pinout as those used for input (see above), but with a male XLR plug instead of a female one. Note that most consumer HiFi equipment (with optical or phono SPDIF inputs) will only accept signals in `Consumer' format!This is necessary when Dolby AC-3 encoded data is sent to external decoders (surround-sound receivers, television sets etc. with AC3 digital inputs), as these decoders would otherwise not recognize the data as AC-3. 16. 3 MIDI Fireface 800 offers one MIDI I/O via 5-pin DIN jacks. Using MIDI capable software, these ports can be accessed under the name Fireface Midi. Using more than one Fireface, the operating system adds a consecutive number to the port name, like Fireface MIDI (1) etc. Since driver version 1. 6, the (MME) MIDI input port supports multi-client operation. A MIDI input signal can be distributed to several programs at the same time. Additionally the GSIF-2 Low Latency MIDI port is available for use with Gigastudio 3.

Based on the highly efficient jitter suppression, the Fireface refreshes and cleans up any clock signal, and provides it as reference clock at the BNC output (see section 24). Input The Fireface's transformer isolated word clock input is active when Pref. Sync Ref in the Settings dialog has been switched to Word Clock, the clock mode AutoSync has been activated, and a valid word clock signal is present. The signal at the BNC input can be Single, Double or Quad Speed, the Fireface 800 automatically adapts to it. As soon as a valid signal is detected, the WC LED is lit, and the Settings dialog shows either Lock or Sync (see chapter 30. 1). Thanks to RME's Signal Adaptation Circuit, the word clock input still works correctly even with heavily mis-shaped, dc-prone, too small or overshoot-prone signals. Thanks to automatic signal centering, 300 mV (0. 3V) input level are sufficient in principle. An additional hysteresis reduces sensitivity to 1. 0 V, so that over- and undershoots and high frequency disturbances don't cause a wrong trigger. The Fireface's word clock input is shipped as high impedance type (not terminated). Use a small pencil or similar and carefully push the blue switch so that it snaps into its lock position. [. . . ] That's how they achieve their outstanding performance and sonic clarity. Add the doubled (quadrupled) bandwidth, and a wideband measurement will show a siginificant drop in SNR, while the human ear will notice absolutely no change in the audible noise floor. 28. 7 SteadyClock The SteadyClock technology of the Fireface 800 guarantees an excellent performance in all clock modes. Thanks to a highly efficient jitter suppression, the AD- and DA-conversion always operates on highest sonic level, being completely independent from the quality of the incoming clock signal. SteadyClock has been originally developed to gain a stable and clean clock from the heavily jittery MADI data signal (the embedded MADI clock suffers from about 80 ns jitter). [. . . ]
