1. Introduction Thank you for choosing the RME Hammerfall DSP system. This unique audio system is capable of transferring analog and 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.
4.
The rear panel of the Multiface II has eight analog inputs and outputs, the Power socket (only necessary with CardBus/ExpressCard operation), Word Clock input and output, and both digital inputs and outputs ADAT and SPDIF. ADAT I/O (TOSLINK): Can also be used as optical SPDIF input and output, if set up accordingly in the Settings dialog. The Settings dialog is started by clicking on the hammer symbol in the Task Bar's system tray.
User's Guide Multiface II Driver Installation and Operation - Windows User's Guide HDSP System Multiface II © RME 9
6. Hardware Installation 6.1 PCI / PCIe Card Before installing the card, please make sure the computer is switched off and the power cable is disconnected from the mains supply. Inserting or removing the card while the computer is in operation can cause irreparable damage to both motherboard and card! 1. Disconnect the power cord and all other cables from the computer. 2. Remove the computer's housing. Further information on how to do this can be obtained from your computer’s instruction manual. 3.
7. Driver and Firmware 7.1 Driver Installation After the interface has been installed correctly (see 6. Hardware Installation), and the computer has been switched on, Windows will recognize the new hardware component and start its ‘Hardware Wizard’. Insert the RME Driver CD into your CD-ROM drive, and follow further instructions which appear on your computer screen. The driver files are located in the directory \WDM on the RME Driver CD.
7.4 Firmware Update The Flash Update Tool updates HDSP PCI, PCIe, CardBus and ExpressCard to the latest version. It requires an already installed driver. Start the program hdsp_wdm_fut.exe (for all HDSP cards) or pcie_fut.exe (for all HDSPe cards). The Flash Update Tool displays the current revision of the HDSP interface, and whether it needs an update. If so, then please manually select if a PCI card (desktop computer) or a CardBus card (laptop) shall be flashed. Next simply press the 'Update' button.
8. Configuring the Multiface II 8.1 Settings Dialog Configuration of the HDSP system Multiface is done via its own settings dialog.
Clock Source The unit can be configured to use its own clock (Internal = Master), or one of the input signals (Word, SPDIF, ADAT). If the selected source isn't available (Input Status No Lock), the unit will change to the next available one (this behaviour is called AutoSync). If none is available then the internal clock is used. The current clock source is displayed as Current. SPDIF In Defines the input for the SPDIF signal. 'Optical' relates to the optical TOSLINK input, 'Coaxial' to the RCA socket.
8.2 Clock Modes - Synchronization In the digital world, all devices must be either Master (clock source) or Slave (clock receiver). Whenever several devices are linked within a system, there must always be a single master clock. A digital system can only have one master! If the HDSP’s clock mode is set to 'Master', all other devices must be set to ‘Slave’. The HDSP system utilizes a very user-friendly, intelligent clock control, called AutoSync.
9. Operation and Usage 9.1 Playback The HDSP system can play back audio data in supported formats only (sample rate, bit resolution). Otherwise an error message appears (for example at 22 kHz and 8 bit). In the audio application being used, HDSP must be selected as output device. This can often be found in the Options, Preferences or Settings menus under Playback Device, Audio Devices, Audio etc. We strongly recommend switching off all system sounds (via >Control Panel /Sounds<).
9.2 DVD-Playback (AC-3/DTS) AC-3 / DTS When using popular DVD software player like WinDVD and PowerDVD, their audio data stream can be sent to any AC-3/DTS capable receiver using the HDSP SPDIF output. For this to work, the WDM SPDIF device has to be selected in >Control Panel/ Sounds and Multimedia/ Audio< or >Control Panel/ Sound/Playback<. Also check 'use preferred device only'. The DVD software's audio properties now show the options 'SPDIF Out' or similar.
9.3 Notes on WDM The driver offers a WDM streaming device per stereo pair, like HDSP Multiface (1+2). WDM streaming is Microsoft's current driver and audio system, directly embedded into the operating system. WDM streaming is hardly usable for professional music purposes, as all data is processed by the so called Kernel Mixer, causing a latency of at least 30 ms.
9.4 Channel Count under WDM The HDSP system’s ADAT optical ports allow to record sample rates of up to 96 kHz using a standard ADAT recorder. For this to work single-channel data is spread to two ADAT channels using the Sample Multiplexing technique. This reduces the number of available ADAT channels from 8 to 4. When the HDSP system changes into Double Speed (88.2/96 kHz) mode the ADAT devices 5/6 and 7/8 are still found in the list, but no longer functional.
9.6 Analog Recording For recordings via the analog inputs the corresponding record device has to be chosen (HDSP Analog (x+x)). The input sensitivity of the analog inputs can be adjusted using the front panel switch ANALOG LEVEL INPUTS to meet the most often used studio levels, see chapter 22.1. It often makes sense to monitor the input signal or send it directly to the output. This can be done at zero latency using TotalMix (see chapter 25).
10. Operation under ASIO 10.1 General Start the ASIO software and select ASIO Hammerfall DSP as the audio I/O device. The Multiface supports ASIO Direct Monitoring (ADM). The Multiface’s MIDI I/O can be used with both MME MIDI and DirectMusic MIDI. 10.2 Channel Count under ASIO At a sample rate of 88.2 or 96 kHz, the ADAT optical input and output operate in S/MUX mode, so the number of available channels per port is reduced from 8 to 4.
10.3 Known Problems If a computer does not provide sufficient CPU-power and/or sufficient PCI-bus transfer rates, then drop outs, crackling and noise will appear. Raising the buffer size in the Settings dialog of the HDSP system helps in most cases. It is also recommended to deactivate all PlugIns to verify that these are not the reason for such effects. Another common source of trouble is incorrect synchronization.
12. DIGICheck Windows The DIGICheck software is a unique utility developed for testing, measuring and analysing digital audio streams. Although this Windows software is fairly self-explanatory, it still includes a comprehensive online help. DIGICheck 5.34 operates as multi-client ASIO host, therefore can be used in parallel to any software, be it WDM or ASIO, with both inputs and outputs (!). The following is a short summary of the currently available functions: • Level Meter.
13. Hotline – Troubleshooting The newest information can always be found on our website www.rme-audio.com, section FAQ, Latest Additions. The dialog 'New hardware component found’ does not appear: • Check whether the CardBus card is completely inserted into the PCMCIA slot, or the PCI interface is correctly inserted in the PCI slot. The input signal cannot be monitored in real-time • ASIO Direct Monitoring has not been enabled, and/or monitoring has been disabled globally.

14. Hardware Installation 14.1 PCIe Card Before installing the card, please make sure the computer is switched off and the power cable is disconnected from the mains supply. Inserting or removing the card while the computer is in operation can cause irreparable damage to both motherboard and card! 1. Disconnect the power cord and all other cables from the computer. 2. Remove the computer's housing. Further information on how to do this can be obtained from your computer’s instruction manual. 3.
15. Driver and Firmware 15.1 Driver Installation First fit the card (see 14. Hardware Installation), then switch on the computer and install the drivers from the RME Driver CD. The driver file is located in the folder HDSPe Series. Installation works automatically by a double-click on the file hdspe.pkg. RME recommends to download the latest driver version from the RME website! If done, the procedure is as follows: Double-click onto hdspe_x86_xx.
16. Configuring the Multiface II 16.1 Settings Dialog Configuring the Multiface II is done via its own settings dialog. The panel 'Settings' can be opened by clicking on the hammer icon in the dock. The mixer of the Hammerfall DSP System, TotalMix, can be opened by clicking on the mixer icon in the dock. The Hammerfall DSP’s hardware offers a number of helpful, well thought-of practical functions and options which affect how the card operates - it can be configured to suit many different requirements.
I/O Box Disconnect interrupts the communication between I/O-box and PCI or CardBus card. In case the Multiface has been configured using the Settings dialog and TotalMix, Disconnect allows to use it Stand-Alone (without a connected computer), after a power supply has been attached.
16.2 Clock Modes - Synchronisation In the digital world, all devices are either the ‘Master’ (clock source) or a ‘Slave’ synchronized to the master. Whenever several devices are linked within a system, there must always be a single master clock. The Hammerfall DSP’s intelligent clock control is very user-friendly, being able to switch between clock modes automatically. Selecting AutoSync will activate this mode. In AutoSync mode, the system constantly scans all digital inputs for a valid signal.
If several digital devices are to be used simultaneously in a system, they not only have to operate with the same sample frequency but also be synchronous with each other. This is why digital systems always need a single device defined as ‘master’, which sends the same clock signal to all the other (‘slave’) devices. RME’s exclusive SyncCheck technology (first implemented in the Hammerfall) enables an easy to use check and display of the current clock status.
17. Mac OS X FAQ 17.1 Round about Driver Installation The driver with the file suffix zip provided by RME is a compressed archive. Zip is directly supported by OS X, a double click on the file is all one needs to do. The driver consists of a package file (pkg). A double click will start the OS X installer. The actual audio driver appears as a kernel extension file. The installer copies it to >System/ Library/ Extensions<. Its name is HDSPMADI.kext.
17.5 Channel Count under Core Audio At a sample rate of 88.2 or 96 kHz, the ADAT optical input and output operates in S/MUX mode, so the number of available channels is reduced from 8 to 4. It is not possible to change the number of Core Audio devices without a reboot of the computer. Therefore whenever the Fireface changes into Double Speed (88.2/96 kHz) mode all devices stay present, but become partly inactive.
19. DIGICheck Mac The DIGICheck software is a unique utility developed for testing, measuring and analysing digital audio streams. Although this Windows software is fairly self-explanatory, it still includes a comprehensive online help. DIGICheck 0.64 operates in parallel to any software, showing all input data. The following is a short summary of the currently available functions: • Level Meter. High precision 24-bit resolution, 2/8/18 channels.
User's Guide Multiface II Disconnect Mode, Connections and TotalMix User's Guide HDSP System Multiface II © RME 35
21. Disconnect Mode RME's exclusive Disconnect mode lets you adjust level, input selection and signal mix via your computer, and simply detach the Multiface afterwards. With this, a stand-alone operation of the Multiface gets possible.
22.2 Line Outputs The eight short circuit protected, low impedance line outputs are available as 1/4" TRS jacks on the back of the unit. The electronic output stage is built in a servo balanced design which handles unbalanced (mono jacks) and balanced (stereo jacks) correctly.
23. Digital Connections 23.1 ADAT The ADAT optical input of the HDSP system is fully compatible with all ADAT optical outputs. RME's unsurpassed 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 sufficient for connection. More information on Double Speed (S/MUX) can be found in chapter 30.3. ADAT In Interface for a device sending an ADAT signal to the Multiface.
The Multiface’s new output header is optimized for largest compatibility with other digital devices: • • • • • • • 32 kHz, 44.1 kHz, 48 kHz, 88.
24. Word Clock 24.1 Technical Description and Usage In the analog domain one can connect any device to another device, a synchronization is not necessary. Digital audio is different. It uses a clock, the sample frequency. The signal can only be processed and transmitted when all participating devices share the same clock. If not, the signal will suffer from wrong samples, distortion, crackle sounds and drop outs.
The word clock input of the Hammerfall DSP is a high-impedance type ensuring maximum flexibility, and is therefore not terminated. If normal termination is necessary (e.g. because Hammerfall DSP is the last device in the chain), simply connect a T-adapter to its BNC input jack, connect the cable supplying the word clock signal to one arm of the T-adapter and terminate the other with a 75 Ohm resistor (as a short BNC plug).

25. TotalMix: Routing and Monitoring 25.1 Overview The Multiface includes a powerful digital real-time mixer, the Hammerfall DSP mixer, based on RME’s unique, sample-rate independent TotalMix technology. It allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any hardware outputs. Here are some typical applications for TotalMix: • Setting up delay-free submixes (headphone mixes).
User's Guide HDSP System Multiface II © RME 45
25.2 The User Interface The visual design of the TotalMix mixer is a result of its capability to route hardware inputs and software playback channels to any hardware output. The Multiface provides 18 input channels, 18 software playback channels, and 20 hardware output channels: 36 channels don't fit on the screen side by side, neither does such an arrangement provide a useful overview.
25.3 The Channels A single channel consists of various elements: Input channels and playback channels each have a mute and solo button. Below there is the panpot, realized as indicator bar (L/R) in order to save space. In the field below, the present level is displayed in RMS or Peak, being updated about every half a second. Overs (overload) are indicated here by an additional red dot. Next is the fader with a level meter.
You see, it is very easy to set up a specific submix for whatever output: select output channel, set up fader and pans of inputs and playbacks – ready! For advanced users sometimes it makes sense to work without Submix View. Example: you want to see and set up some channels of different submixes simultaneously, without the need to change between them all the time. Switch off the Submix View by a click on the green button.
You will certainly have noticed that the signal at the outputs 7/8 did not change while you were routing channel 4 to other outputs and setting different gain values for those. With all analog and most digital mixing desks, the fader setting would affect the level for every routed bus - not so for TotalMix. TotalMix allows for setting all fader values individually. Therefore the faders and the panpots jump to the appropriate setting as soon as another routing is chosen.
25.7 The Quick Access Panel This section includes additional options, further improving the handling of TotalMix. The Master buttons for Mute and Solo have already been described, they allow for group-based working with these functions. In the View section the single mixer rows can be made visible or invisible. If the inputs are not needed for a pristine playback mix, the whole upper row falls out of the picture after a click on the Input button.
Mouse: The original factory presets can be reloaded by holding down the Ctrl-key and clicking on any preset button. Alternatively the files described above can be renamed, moved to a different directory, or being deleted. Keyboard: Using Ctrl and any number between 1 and 8 (not on the numeric keypad!) will load the corresponding factory default preset. The key Alt will load the user presets instead. When loading a preset file the file name will be displayed in the title bar of the TotalMix window.
25.9 The Monitor Panel The Monitor panel provides several options usually found on analog mixing desks. It offers quick access to monitoring functions which are needed all the time in typical studio work. Monitor Main Use the drop down menu to select the hardware outputs where your main monitors are connected to. Dim A click on this button will lower the volume of the Monitor Main output by an amount set up in the Preferences dialog (see below).
MIDI Controller MIDI In: Input where TotalMix receives MIDI Remote data. MIDI Out: Output where TotalMix sends MIDI Remote data. Mackie Control Options Enable Protocol Support: When disabled TM FX will only react on the Control Change commands of chapter 28.5. Enable full LCD support: Activates full Mackie Control LCD support with eight channel names and eight volume/pan values. Send Level Messages: Activates the transmission of the level meter data. Stereo Pan Law The Pan Law can be set to -6 dB, -4.
25.12 Hotkeys In many situations TotalMix can be controlled quickly and comfortably by the keyboard, making the mixer setup considerably easier and faster. The Shift-key for the fine mode for faders and panpots has already been mentioned. The Ctrl-key can do far more than changing the routing pairwise: • Clicking anywhere into the fader area with the Ctrl-key pressed, sets the fader to 0 dB. • Clicking anywhere into the pan area with the Ctrl-key pressed, sets the panorama to meaning Center.
25.13 Menu Options Always on Top: When active (checked) the TotalMix window will always be on top of the Windows desktop. Note: This function may result in problems with windows containing help text, as the TotalMix window will even be on top of those windows, so the help text isn't readable. Deactivate Screensaver: When active (checked) any activated Windows screensaver will be disabled temporarily. Ignore Position: When active, the windows size and position stored in a file or preset will not be used.
25.15 Level Meter The Multiface II calculates all the display values Peak, Over and RMS in hardware, in order to be capable of using them independent of the software in use, and to significantly reduce the CPU load. Tip: This feature, the Hardware Level Meter, is used by DIGICheck (see chapter 12/19) to display Peak/RMS level meters of all channels, nearly without any CPU load. The level meters integrated in TotalMix - considering their size - cannot be compared with DIGICheck.
26. TotalMix: The Matrix 26.1 Overview The mixer window of TotalMix looks and operates similar to mixing desks, as it is based on a conventional stereo design. The matrix display presents a different method of assigning and routing channels, based on a single channel or monaural design. The matrix view of the HDSP has the looks and works like a conventional patchbay, adding functionality way beyond comparable hardware and software solutions.
26.4 Advantages of the Matrix The Matrix not always replaces the mixer view, but it significantly enhances the routing capabilities and - more important - is a brilliant way to get a fast overview of all active routings. It shows you in a glance what's going on. And since the Matrix operates monaural, it is very easy to set up specific routings with specific gains.
27.2 Selection and Group-based Operation Click on the white name label of channel 1 and 2 in TotalMix. Be sure to have channel 3's fader set to a different position and click on its label too. All three labels have changed to the colour orange, which means they are selected. Now moving any of these faders will make the other faders move too. This is called 'building a group of faders', or ganging faders, maintaining their relative position.
27.5 Recording a Subgroup (Loopback) TotalMix supports a routing of the subgroup outputs (=hardware outputs, bottom row) to the recording software. Instead of the signal at the hardware input, the signal at the hardware output is sent to the record software. This way, complete submixes can be recorded without an external loopback cable. Also the playback of a software can be recorded by another software. To activate this function, click on the white label in the third row while holding down the Ctrl-key.
Recording a Software's playback In real world application, recording a software's output with another software will show the following problem: The record software tries to open the same playback channel as the playback software (already active), or the playback one has already opened the input channel which should be used by the record software. This problem can easily be solved.
As explained in chapter 27.5, the hardware input of channel 10 now no longer feeds the record software, but is still connected to TotalMix (and thus to the Compressor). The record software receives the signal of submix channel 10 instead – the Compressor's return path. 27.8 MS Processing The mid/side principle is a special positioning technique for microphones, which results in a mid signal on one channel and a side signal on the other channel.
28. TotalMix MIDI Remote Control 28.1 Overview TotalMix can be remote controlled via MIDI. It is compatible to the widely spread Mackie Control protocol, so TotalMix can be controlled with all hardware controllers supporting this standard. Examples are the Mackie Control, Tascam US-2400 or Behringer BCF 2000. Additionally, the stereo output faders (lowest row) which are set up as Monitor Main outputs in the Monitor panel can also be controlled by the standard Control Change Volume via MIDI channel 1.
28.3 Setup • Open the Preferences dialog (menu Options or F3). Select the MIDI Input and MIDI Output port where your controller is connected to. • When no feedback is needed (when using only standard MIDI commands instead of Mackie Control protocol) select NONE as MIDI Output. • Check Enable MIDI Control in the Options menu. 28.4 Operation The channels being under MIDI control are indicated by a colour change of the info field below the faders, black turns to yellow.
28.5 Simple MIDI Control The stereo output faders (lowest row) which are set up as Monitor Main outputs in the Monitor panel can also be controlled by the standard Control Change Volume via MIDI channel 1. With this, the main volume of the Multiface is controllable from nearly any MIDI equipped hardware device. Even if you don't want to control all faders and pans, some buttons are highly desired to be available in 'hardware'.
Examples for sending MIDI strings*: - Set input 1 to 0 dB: B0 66 40 - Set input 17 to maximum attenuation: B1 66 0 - Set playback 1 to maximum: B4 66 7F - Set Output 16 to 0 dB: B8 75 40 *Note: Sending MIDI strings requires the use of programmer's logic for the MIDI channel, starting with 0 for channel 1 and ending with 15 for channel 16. 28.6 Loopback Detection The Mackie Control protocol requires feedback of the received commands, back to the hardware controller.

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 interface directly to the output. Since then, the idea behind has become one of the most important features of modern hard disk recording.
Note: Cubase and Nuendo display the latency values signalled from the driver separately for record and playback. While with our former cards these values equalled exactly the buffer size (for example 3 ms at 128 samples), the Multiface displays an additional millisecond – the time needed for the AD/DA-conversion. Core Audios Safety Offset Under OS X, every audio interface has to use a so called safety offset, otherwise Core Audio won't operate click-free. The Multiface uses a safety offset of 32 samples.
30.4 AES/EBU - SPDIF The most important electrical properties of 'AES' and 'SPDIF' can be seen in the table below. AES/EBU is the professional balanced connection using XLR plugs. The standard is being set by the Audio Engineering Society based on the AES3-1992. For the 'home user', SONY and Philips have omitted the balanced connection and use either Phono plugs or optical cables (TOSLINK). The format called S/P-DIF (SONY/Philips Digital Interface) is described by IEC 60958.
