1. Introduction Thank you for choosing the RME HDSPe AIO Pro. This unique audio card is capable of transferring digital and analog audio data directly to Windows and Mac computers. The latest Plug and Play technology guarantees a simple installation, even for the inexperienced user. Numerous unique features like a well thought-out Settings dialog and an integrated routing solution realize a quick, comfortable and efficient operation of the HDSPe AIO Pro.
5. Hardware Installation To simplify installation it is recommended to first install the drivers before the unit is connected to the computer. But it will also work the other way round. ! Before installing the PCI Express card, please make sure the computer is switched off and the power cable is disconnected from mains supply. Inserting or removing the card while the computer is in operation can cause irreparable damage to both motherboard and card! 1.
6.2 Internal Connectors INT (X1202) This internal digital input can be used with both SPDIF and ADAT format. It is activated by selecting SPDIF In – Internal in the Settings dialog. SPDIF Connection to an internal CD-ROM drive with digital audio output. Allows for a direct transfer of digital audio data within the computer. Connection to an SPDIF output of another card.

7. Driver and Firmware 7.1 Driver Installation After the HDSPe AIO Pro card has been installed correctly (see 5. Hardware Installation), and the computer has been switched on, Windows will recognize the new hardware component and start its ‘Hardware Wizard’. In case the drivers had not been installed before exit the assistant. RME is constantly improving the drivers. Please download the latest drivers from the RME website. Driver version 4.30 or higher is available via http://rme.to/downloads.
8. Configuring the HDSPe AIO Pro 8.1 Settings Dialog Configuration of the HDSPe AIO Pro is done via its own settings dialog.
WDM Devices Allows to freely set which I/Os are available as WDM devices, if these are stereo or multichannel devices (up to 8 channels), and if one or multiple of the currently active WDM devices should have the Speaker property. More details are found in chapter 8.3. Clock Mode Sample Rate Sets the currently used sample rate.
Input Status SyncCheck indicates whether there is a valid signal (Lock, No Lock) for each input (ADAT, SPDIF, AES, Word/TCO and internal Sync), or if there is a valid and synchronous signal (Sync). In the third row the sample rate measured by the hardware is shown. 8.2 Settings dialog - Pitch Usually soundcards and audio interfaces generate their internal clock (master mode) by a quartz. Therefore the internal clock can be set to 44.1 kHz or 48 kHz, but not to a value in between.
8.3 Option WDM Devices The area WDM Devices gives configuration access, a status display showing the number of currently enabled WDM devices, and a listbox to select between Stereo or Multi-Channel devices. The number represents both record and playback devices, so ‘1’ means one input and one output device. The screenshot to the right shows the stereo WDM devices available with the HDSPe AIO Pro, and that only Analog 1/2 has been activated. Any number can be activated.
8.4 Tab Global This tab includes several options that work on all currently installed cards. Lock Registry Default: off. Checking this option brings up a dialog to enter a password. Changes in the Settings dialog are no longer written to the registry. As the settings are always loaded from the registry when starting the computer, this method provides an easy way to define an initial state of the HDSPe AIO Pro. Optimize Multi-Client Mixing Default: off.
8.5 Clock Modes - Synchronisation 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 card’s clock mode is set to 'Internal', all other devices must be set to ‘Slave’. The HDSPe AIO Pro’s utilizes a very user-friendly, intelligent clock control, called AutoSync.
9. Operation and Usage 9.1 Playback In the audio application being used, HDSPe AIO Pro 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. ! WDM playback devices are not available if the number of WDM devices is set to 0 in the Settings dialog.
Note 1: Selecting the AIO Pro to be used as system playback device is against our recommendation, as professional interfaces should not be disturbed by system events. Make sure to reassign the selection after usage or to disable any system sounds (tab Sounds, scheme 'No audio'). Note 2: The DVD player will be synced backwards from the AIO Pro. This means when using AutoSync and/or word clock, the playback speed and pitch follows the incoming clock signal. 9.
9.5 Digital Recording 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 rate, lock and sync status) in the Settings dialog. The sample rate shown in the Settings dialog (see chapter 8.
10. Operation under ASIO 2.0 10.1 General Start the ASIO software and select ASIO Hammerfall DSP as the audio I/O device. The HDSP system supports ASIO Direct Monitoring (ADM). The HDSPe AIO Pro MIDI I/O can be used with both Windows 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 outputs operate in S/MUX mode, so the number of available channels per port is reduced from 8 to 4. At a sample rate of 176.
10.3 Known Problems If a computer does not provide sufficient CPU-power and/or sufficient PCIe-bus transfer rates, then drop outs, crackling and noise will appear. We recommend to deactivate all PlugIns to verify that these are not the reason for such effects. A typical source of trouble is incorrect synchronization. ASIO does not support asynchronous operation, which means that the input and output signals not only have to use the same sample frequency, but also have to be in sync.
12. DIGICheck 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 5.93 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. Driver and Flash Update 13.1 Driver Installation After fitting the card (see 5. Hardware Installation) and switching on the computer install the drivers. RME is constantly improving the drivers. Please download the latest drivers from the RME website at http://rme.to/downloads. Unzip the downloaded file and start the driver installation by double-clicking hdspe.pkg. During driver installation the programs Totalmix (TotalMix FX) and HDSPe Settings are copied to the Applications folder.
14. Configuring the HDSPe AIO Pro 14.1 Settings Dialog Configuring the HDSPe AIO Pro is done via its own settings dialog the app HDSPe Settings. The mixer of the HDSPe AIO Pro, TotalMix FX, can be opened by starting the app Totalmix. The HDSPe’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.
SPDIF Out The SPDIF output signal is constantly available at the phono plug. After selecting 'Optical' it is also routed to the optical TOSLINK output. Details about ‘Professional’ see chapter 23.3. Phones Choice of the reference level and with this of the level at the analog phones output. Lo-Power offers reduced background noise which is useful with highly sensitive headphones. Word Clock Out The word clock output signal usually equals the current sample rate.
14.2 Clock Modes - Synchronisation In the digital world, all devices must be either Master (clock source) or Slave (clock receiver). Whenever several devices are linked there must always be a single master clock. ! A digital system can only have one master! If the HDSPe’s clock mode is set to 'Master', all other devices must be set to ‘Slave’. The HDSPe AIO Pro’s intelligent clock control is very user-friendly, being able to switch between clock modes automatically.
15. Mac OS X FAQ 15.1 MIDI doesn't work In some cases MIDI does not work after the installation of the HDSPe driver. 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. The HDSPe MIDI driver is a plugin. During installation it will be copied to Library / Audio / MIDI Drivers. It's name is HDSP MADI MIDI.plugin.
15.5 Various Information The driver requires 10.9 or higher. Older versions of OS X are not supported. Programs that don't support card or channel selection will use the device chosen as Input and Output in the System Preferences – Sound panel. Via Launchpad – Other – Audio MIDI Setup the HDSPe AIO Pro can be configured for the system wide usage in more detail. Programs that don't support channel selection will always use channels 1/2, the first stereo pair.
17. DIGICheck Mac The DIGICheck software is a unique utility developed for testing, measuring and analysing digital audio streams. Although this app is fairly self-explanatory, it still includes a comprehensive online help. DIGICheck 0.73 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, 2/8/16 channels.
User's Guide HDSPe AIO Pro Connections User's Guide HDSPe AIO Pro © RME 33
18. Analog Connections 18.1 Line Inputs The HDSPe AIO Pro has an unbalanced stereo Line input via RCA connectors. The optional analog XLR breakout cable turns the inputs into fully balanced ones. The electronic input stage is built in a servo balanced design which handles unbalanced and balanced signals correctly, automatically adjusting the level reference. ! When using unbalanced cables or sources with TRS jacks: be sure to connect the 'ring' contact of the TRS jack to ground.
18.3 Headphones The channels Phones of the HDSPe AIO Pro are available via an 1/4" TRS jack (stereo output). The High Power² output easily drives low impedance headphones. The output’s volume is adjusted via TotalMix. Additionally, the Settings dialog provides the level settings Hi-Power (equals +19 dBu @ 0 dBFS) and Lo-Power (equals +7 dBu @ 0 dBFS). These outputs represent ideal headphone outputs. Eventually as technically they are also ideal line outputs.
19.2 AES/EBU The HDSPe AIO Pro digital breakout cable provides one XLR AES/EBU input and output each. Connection is accomplished using balanced cables with XLR plugs. Input and Output are transformer-balanced and ground-free. Besides the audio data, digital signals in SPDIF or AES/EBU format contain a channel status coding. The incoming channel status is completely ignored. The output signal coding of the HDSPe AIO Pro has been implemented according to AES3-1992 Amendment 4: 32 / 44.
19.3 SPDIF (Coaxial, Optical) Input The SPDIF input (optical/coaxial) is configured in the Settings dialog, available by a click on the hammer symbol in the Task Bar's system tray. The HDSPe AIO Pro accepts all commonly used digital sources as well as SPDIF and AES/EBU. Output Identical signals are available at both the optical and the coaxial output. An obvious use for this would be to connect two devices, i.e. using the HDSPe as a distributor (1 on 2).

20. Routing and Monitoring 20.1 Overview The HDSPe AIO Pro includes a powerful digital real-time mixer, based on RME’s unique, samplerate 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). The HDSPe AIO Pro allows for up to 8 fully independent stereo submixes.
User's Guide HDSPe AIO Pro © RME 41
20.2 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 HDSPe AIO Pro provides up to 14 input channels, 16 software playback channels, and 16 hardware output channels: TotalMix can be used in the above view (View Options 2 Rows).
20.3 The Channels A single channel can be switched between mono and stereo mode. The mode is set in the channel settings. Channel name. The name field is the preferred place to select a channel by a mouse click. A double click opens a dialog to assign a different name. The original name will be shown when activating the option Names in the View Options. Panorama. Routes the input signal freely to the left and right routing destination (lower label, see below).
The lowest field shows the current routing target. A mouse click opens the routing window to select a routing target. The list shows all activated routings of the current channel by arrows in front of the listed entries, the current one is shown in bold letters. An arrow is only shown with an activated routing. A routing is seen as activated when audio data is sent. As long as the fader is set to −∞ the current routing will be shown in bold letters, but not have an arrow in the front. Trim Gain.
A click on the tool symbol opens the channel’s Settings panel. The panel includes the following elements: Stereo. Switches the channel to mono or stereo mode. Width. Setting the stereo width. 1.00 equals full stereo, 0.00 mono, -1.00 swapped channels. MS Proc. Activates M/S processing within the stereo channel. Monaural information is sent to the left channel, stereo information to the right. Phase L. Inverts the phase of the left channel by 180°. Phase R. Inverts the phase of the right channel by 180°.
20.4 Section Control Room In the section Control Room the menu Assign is used to define the Main Out which is used for listening in the studio. For this output the functions Dim, Recall, Mono, Talkback and External Input are automatically applied. Additionally the channel will be shifted from the Hardware Outputs into the Control Room section, and renamed Main. The same happens when assigning Main Out B or the Phones.
20.5 The Control Strip The Control Strip on the right side combines different functions that are either required globally, or constantly used, and therefore should not be hidden in a menu. Still using the menu entry Window, Hide Control Strip, the Control Strip is shifted out of the visible area to gain more space for other elements. The areas described in the following chapters can be minimized by a click on the triangle in their title bar. Device selection.
20.5.1 View Options The field View Options combines different functions of routing, the level meters and the mixer view. Routing Mode Submix: The Submix view (default) is the preferred view and delivers the quickest overview, operation and understanding of TotalMix. The click on one of the Hardware Output channels selects the respective submix, all other outputs are darkened. At the same time all routing fields are set to this channel.
20.5.2 Snapshots - Groups Snapshots. Snapshots include all mixer settings, but no graphical elements like window positions, window size, number of windows, visible EQs or Settings, scroll states, Presets etc. Only the state wide/narrow of the channels is registered. Moreover the Snapshot is only temporarily stored. Loading a Workspace causes the loss of all stored Snapshots, when these all had not been saved before in a Workspace, or separately via File / Save Snapshot as.
20.5.3 Channel Layout - Layout Presets To maintain overview within TotalMix FX channels can be hidden. Channels can also be excluded from being remoted. Under Options / Channel Layout a dialog lists all I/Os with their current state. Selecting one or several channels enables the options to the right: Hide Channel in Mixer/Matrix. The selected channels are no longer shown in TotalMix FX, nor are they available via MIDI or OSC remote control. Hide Channel in MIDI Remote 1-4.
After finishing those settings the whole state can be stored as Layout Preset. A click on Store and the desired memory slot makes the current channel layout recallable anytime. The button All makes all channels temporarily visible again. With a simple click on a button it will then be possible to easily switch views of only the channels involved with the mixing of the drum section, the horn section, the violins, or any other useful view.
20.6 Preferences The dialog Preferences can be opened via the Options menu or directly via F2. Level Meters Full scale samples for OVR. Number of consecutive samples to trigger an over detection (1 to 10). Peak Hold Time. Hold time of the peak value. Adjustable from 0.1 up to 9.9 s. RMS +3 dB. Shifts the RMS value by +3 dB, so that full scale level is identical for Peak and RMS at 0 dBFS. Mixer Views FX Send follows highest Submix. FX Send follows Main Out. Not available for the AIO Pro - no FX.
Graphics Use D2D (Change requires restart). Default on. Can be deactivated to use a compatible but CPU-taxing graphics mode, in case graphics problems show up. Brightness correction. Set TotalMix FX screen brightness to your taste, matching the monitor setting or the environment. Store Setting for All Users (Restart required). See next chapter. Special Options Lock User Interface. Default off. Can be activated to freeze the current mix state.
20.7 Settings The dialog Settings can be opened via the Options menu or directly via F3. 20.7.1 Mixer Page On the mixer page some typical settings for the mixer operation are set, like Talkback source, Dim amount when Talkback is active, the stored main volume or the input used for the External Input function. Talkback Input. Selects the input channel of the Talkback signal (microphone in control room). Default: None. Dim. Amount of attenuation of the signals routed to the Phones in dB.
20.7.2 MIDI Page The MIDI page has four independent settings for up to four MIDI remote controls, using CC commands or the Mackie Control protocol. Index Select one of four settings pages and thus remote controls. Settings are remembered automatically. To activate or deactivate any of the four remote controls check or uncheck ‘In Use’. MIDI Remote Control MIDI In. Input where TotalMix receives MIDI Remote data. MIDI Out. Output where TotalMix sends MIDI Remote data. Disable MIDI in background.
20.7.3 OSC Page The OSC page has four independent settings for up to four MIDI remote controls via Open Sound Control (OSC). This is a network based remote protocol that can be used for example by Apple’s iPad with the app TouchOSC or Lemur to wirelessly remote control TotalMix FX running on a Mac or Windows computer. Index Select one of four settings pages and thus remote controls. Settings are remembered automatically. To activate or deactivate any of the four remote controls check or uncheck ‘In Use’.
20.7.4 Aux Devices The RME OctaMic XTC is a highly flexible hi-quality 8-channel microphone, line and instrument preamp with integrated ADconversion to ADAT, AES/EBU and MADI, plus 4 channels of DA-conversion for monitoring. It can be used as universal front-end for the HDSPe AIO and other interfaces. To simplify operation the most important parameters of the XTC (gain, 48V, Inst/PAD, AutoSet) can be controlled directly from the TotalMix FX input channels.
20.8 Hotkeys and Usage TotalMix FX has many hotkeys and mouse/hotkey combinations to speed up and simplify the usage. The below description refers to Windows. On Mac substitute Ctrl in the below list with the command key (). The Shift key enables a fine-tuning of the gain with all faders and in the Matrix. On all knobs it will speed up the setting. A click on a fader with held down Shift key adds the fader to the temporary fader group.
20.9 Menu Options Deactivate Screensaver: When active (checked) any activated Windows screensaver will be disabled temporarily. 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. Enable MIDI / OSC Control: Activates external MIDI control of the TotalMix mixer.
Operational Mode. Defines TotalMix FX basic operational mode. Choices are Full Mode (default, mixer active, all routing options available), and Digital Audio Workstation Mode (straight playback routing, no input mix). See chapter 23 for details. Network Remote Settings. Settings to remote control TotalMix FX by TotalMix Remote via network. See chapter 24. 20.10 Menu Window Zoom Options 100%, 135%, 200%, 270%.
To maintain overview when the window size has been reduced, the labels are floating. They won't leave the visible area when scrolling. A right mouse click on the labels brings up the context menu with the exact same options as in the mixer view: Copy / Mirror / Paste /Clear input channels and submixes. 21.3 Operation Using the Matrix is a breeze. It is very easy to indentify the current crosspoint, because the outer labels light up in orange according to the mouse position.
22.4 Delete a Submix The easiest and quickest way to delete complex routings is by selection of the according output channel in the mixer view by a right mouse click, and selection of Clear Submix. As TotalMix FX includes an unlimited undo the delete process can be undone without any problem. 22.5 Copy and Paste everywhere The above three tips use functions found in the right click context menu available on all channels of the TotalMix FX mixer view.
As each of the 16 hardware outputs can be routed to the record software, and none of these hardware inputs get lost, TotalMix offers an overall flexibility and performance not rivalled by any other solution. The risk of feedbacks, a basic problem of loopback methods, is low, because the feedback can not happen within the mixer, only when the audio software is switched into monitoring mode.
23. MIDI Remote Control 23.1 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 Main Out in the Control Room section can also be controlled by the standard Control Change Volume via MIDI channel 1.
23.3 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 select NONE as MIDI Output. Check Enable MIDI Control in the Options menu. 23.4 Operation The channels being under Mackie MIDI control are indicated by a colour change of the name field, black turns to brown. The 8-fader block can be moved horizontally and vertically, in steps of one or eight channels.
23.5 MIDI Control The hardware output set up as Main Out can be controlled by the standard Control Change Volume via MIDI channel 1. With this, the main volume of the Digiface USB 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 desirable to be available in 'hardware'. These are mainly the Talkback and the Dim button, and the monitoring options (listen to Phones submixes).
Examples for sending MIDI strings: - Set input 1 to 0 dB: B0 66 68 - Set input 5 to maximum attenuation: B1 6A 0 - Set playback 1 to maximum: B4 66 7F - Set Output 3 to 0 dB: B8 68 68 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.
24. DAW Mode Users that work exclusively with their DAW software, and don’t want to use TotalMix FX for additional routing tasks, need a way to be sure that TotalMix FX currently doesn’t change the DAW’s routing.
25. TotalMix Remote TotalMix Remote is a remote control for TotalMix FX v1.50 and up, to control the hardware mixer and effects in RME audio interfaces. TotalMix Remote mirrors the current state of the host system on the iPad and Windows/Mac computers - the entire mixing state, the complete routing, all FX settings, up to the level meters, and everything in real-time.
Tip The remotes have the option Sync Channel Layouts active as default (in Preferences). This option transfers the Layout Presets and the current Channel Layout state from host to remote. Apart from the channel width state this option makes a mirror-style setup most easy. But when using the remote as individual setup, make sure to disable this option to have independent Layout Presets on the remote. Limitations • Mixer View & GUI.

27. Technical Background 27.1 Lock and SyncCheck Digital signals consist of a carrier and the data. If a digital signal is applied to an input, the receiver has to synchronize to the carrier clock in order to read the data correctly. To achieve this, the receiver uses a PLL (Phase Locked Loop). As soon as the receiver meets the exact frequency of the incoming signal, it is locked. This Lock state remains even with small changes of the frequency, because the PLL tracks the receiver's frequency.
Oversampling While the delays of digital interfaces can be disregarded altogether, the analog inputs and outputs do cause a significant delay. Modern converter chips operate with 64 or 128 times oversampling plus digital filtering, in order to move the error-prone analog filters away from the audible frequency range as far as possible. This typically generates a delay of one millisecond.
27.3 DS - Double Speed Sample rates above 48 kHz were not always taken for granted, and are still not widely used because of the CD format (44.1 kHz) dominating everything. Before 1998 there were no receiver/transmitter circuits available that could receive or transmit more than 48 kHz. Therefore a work-around was used: instead of two channels, one AES line only carries one channel, whose odd and even samples are being distributed to the former left and right channels.
27.5 Noise level in DS / QS Mode The outstanding signal to noise ratio of the HDSPe AIO Pro's AD-converters can be verified even without expensive test equipment, by using record level meters of various software. But when activating the DS and QS mode, the displayed noise level will rise from -117 dB to -109 dB at 96 kHz, and –88 dB at 192 kHz. This is not a failure. The software measures the noise of the whole frequency range, at 96 kHz from 0 Hz to 48 kHz (RMS unweighted), at 192 kHz from 0 Hz to 96 kHz.
