1. Introduction Thank you for choosing the RME Hammerfall DSP system. This unique audio system is capable of transferring digital audio data directly to a computer from practically any device. The latest Plug and Play technology guarantees a simple installation, even for the inexperienced user. The numerous unique features and well thought-out configuration dialog puts the Hammerfall DSP at the very top of the range of computer-based audio interfaces.

Windows will recognize the new hardware component and start its ‘Hardware Wizard’. Insert the RME Driver CD into your CD-ROM drive, and follow fur- ther instructions which appear on your computer screen. The driver files are located in the di- rectory \WDM on the RME Driver CD.
Settings dialog, and the registration of the ASIO driver. Those entries can be re- moved from the registry through a software de-installation request. This request can be found (like all de-installation entries) in Control Panel, Software. Click on the entry 'RME Hammerfall DSP (WDM)'.
Therefore the internal clock can be set to 44.1 kHz or 48 kHz, but not to a value in be- tween. SteadyClock, RME's sensational Low Jitter Clock System, is based on a Direct Digital Synthesizer (DDS). This superior circuitry can generate nearly any frequency with highest pre- cision.

In this case, 'Pref Sync Ref' should be temporarily set to SPDIF. RME’s exclusive SyncCheck technology enables an easy to use check and display of the cur- rent clock status. The status box labelled Input Status indicates whether no signal (‘No Lock’), a valid signal (‘Lock’) or a valid and synchronous signal (‘Sync’) is present at each of the digital...
Once again the same inputs can be used simultaneously. RME's sophisticated tool DIGICheck is an exception to this rule. It operates like an ASIO host, using a special technique to access playback channels already occupied. Therefore DIGICheck is able to analyse and display playback data from any software, no matter which format the software uses.
Unlike analog soundcards which produce empty wave files (or noise) when no input signal is present, digital I/O cards always need a valid input signal to start recording. To take this into account, RME included a comprehensive I/O signal status display (showing sample frequency, lock and sync status) in the Settings dialog.
• Completely multi-client. Open as many measurement windows as you like, on any chan- nels and inputs or outputs! To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe. Follow the instructions prompted on the screen.
17. Hotline – Troubleshooting 17.1 General The newest information can always be found on our website www.rme-audio.de, section FAQ, Latest Additions. The input signal cannot be monitored in real-time • ASIO Direct Monitoring has not been enabled, and/or monitoring has been disabled globally (for example in TotalMix).
First fit the card (see 5. Hardware Installation), then switch on the computer and install the driv- ers from the RME Driver CD. The driver file is located in the folder HDSPe. Installation works automatically by a double-click on the file HDSPe.pkg.

MIDI port. The reason for this is usually visible within the Audio MIDI Setup. It displays no RME MIDI device, or the device is greyed out and therefore inactive. Mostly, removing the greyed out device and searching for MIDI devices again will solve the problem.
20.5 Supported Sample Rates RME's Mac OS X driver supports all sampling frequencies provided by the hardware. Besides 192 kHz and 96 kHz this also includes 32 kHz and 64 kHz. But not any software will support all the hardware's sample rates. The hardware's capabilities can easily be verified in the Audio MIDI Setup.
RayDAT SPDIF L / R RayDAT SPDIF L / R 21. Hotline – Troubleshooting The newest information can always be found on our website www.rme-audio.com, section Sup- port, Macintosh OS. The 8 ADAT channels 25-32 don’t seem to work • The optical output ADAT4 has been switched to 'SPDIF'. The ADAT playback devices are still usable by routing and mixing them in TotalMix to other outputs.
22. Digital Connections 22.1 ADAT The ADAT optical I/Os of the RayDAT are fully compatible to other ADAT devices. RME's un- surpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch operation, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK cable is suffi- cient for connection.
TotalMix provides the means to mix and monitor these on a single stereo output. • Mixing of the input signal to the playback signal (complete ASIO Direct Monitoring). RME not only is the pioneer of ADM, but also offers the most complete implementation of the ADM functions.
TotalMix stores and reads the changed presets from the files preset11.mix to preset81.mix, located in Windows' hidden directory >Documents and Settings, <Username>, Local Settings, Application Data, RME TotalMix<. On the Mac the location is in the folder >User, <Username>, Library / Preferences / Hammerfall DSP<. The first number indi- cates the current preset, the second number the current unit.
Thus it can be a valuable tool for sound optimization and error removal in the studio. Measuring SNR (Signal to Noise) is best done with RME’s free software DIGICheck. The function Bit Statistic includes three different RMS meters for exactly this purpose (RMS unweighted, A-weighted and DC).
28. Tech Info Not all information to and around our products fit in a manual. Therefore RME offers a lot more and detailed information in the Tech Infos. The very latest Tech Infos can be found on our web- site, section Support. These are some of the currently available Tech Infos: Synchronization II (DIGI96 series) Digital audio synchronization - technical background and pitfalls.
30.2 Latency and Monitoring The term Zero Latency Monitoring has been introduced by RME in 1998 for the DIGI96 series of audio cards. It stands for the ability to pass-through the computer's input signal at the inter- face directly to the output. Since then, the idea behind has become one of the most important features of modern hard disk recording.
Latest circuit designs like hi-speed digital synthesizer, digital PLL, 100 MHz sample rate and analog filtering allow RME to realize a completely newly developed clock technology, right within the FPGA at lowest costs. The clock's performance exceeds even professional expectations.
