24 Bit/96 kHz SPDIF - AES/EBU PCI Digital Audio Card

Overview Settings Dialog Technical Specs / Features Unique Technologies

In a short time the DIGI32 series has become the leader in the field of digital I/O cards for PCI bus, thanks to its unsurpassed reliability, absolute data integrity, minimum system load, rock solid drivers and tremendous performance. Now RME proudly presents DIGI96®, the more powerful DIGI32, adding numerous new features and capabilities like Master mode, Enhanced Full Duplex, Zero Latency Monitoring, DIGICheck, AutoSelect, 96 kHz and Non-Audio (AC-3) channel status.

DIGI96 is the result of an intensive development by hardware and software cracks. Like its predecessor it will need only a short time to become the new reference for digital audio PCI bus interfaces, for home and professional use.

The DIGI96 offers drivers for Windows 95/98 (MME, DirectSound, ASIO 2.0, GSIF), Windows NT (MME, ASIO 2.0), Windows 2000/XP (MME, ASIO 2.0, GSIF), MacOS (Sound Manager and ASIO 2.0) and Linux (OSS and ALSA.)

DIGI96 comes with an incredible free utility: DIGICheck, the ultimate measurement, analysis and test tool!


Just click on the DIGI symbol in the systray of the taskbar and the settings dialog of the DIGI96 comes up. The clear structured, easy to understand window plus the unique informative status displays for input and output make your work with the DIGI96 to a real pleasure. With a simple mouse click (or a freely configurable key shortcut) you gain access to the full power of your card.

RME's Settings dialog shows installed and active DIGI96® series' cards, according to their numbering in the system. Therefore even in multicard usage you'll always know which wave device belongs to which card.

These are only some of DIGI96 capabilities. The complete list of features and the differences to the DIGI32 are listed here.

  • AutoSelect
    When using only one input AutoSelect will find the used input automatically. As long as no valid input signal appears (No Lock) the card switches every 0,5 s to the next input and looks for an input signal. AutoSelect stops when it finds a valid signal and starts again when losing it.
  • AutoSync
    With AutoSync activated DIGI96 continuously searches for a valid input signal to lock on the signals clock. So starting a recording on-the-fly is possible (as well as anytime during playback, thanks to Full Duplex) without first having to synchronize the card to the input signal. When using more than one card synchronizing is easy, just spread an input signal to all inputs. Vari-speed is possible over the whole supported sample rate range. In case of 'local loop-back' operation (for example DAT) AutoSync leads to a loss of the digital carrier. Because of this AutoSync can be disabled, the card then works in master mode.
  • Enhanced Full Duplex
    Usual digital audio cards offer Full Duplex operation (simultaneous record and playback.) RME's DIGI96 series is one step ahead. As record and playback circuits are totally separated the DIGI96 series can operate in Enhanced Full Duplex mode. This allows simultaneous record and playback even with different sample rates at input and output.
  • Hardware Selftest
    When loading the driver (while booting Windows) the DIGI96 series performs a hardware selftest. This test is used in production test procedure, but as it lasts only a few hundredths of a second we decided to integrate it into the Windows driver. So when working with any Digi96 you can always be sure that all bits are fully functional. In case of an error a message displays.
  • Hi-Performance
    Normally the hardware does not have any influence in the functions of his product, because all features are the result of the chips used. This is not only true for several features, but also for the data format between hardware, PC and software, which has to be mapped by the driver. But all actions of the driver are also actions of the CPU, ending in additional system load. The DIGI96 series is made out of a FPGA, a completely programmable chip. Thus a piece of hardware was created which works exactly the way a perfect digital I/O card should do. So the main task of the driver of the DIGI96 series is just to set the user's options.
  • SyncAlign®
    SyncAlign includes several methods and techniques to guarantee absolute data alignment with regard to time and channels. The DIGI96 series will NEVER swap channels, regardless what you do with the card and the signals it gets. SyncAlign also controls the timing among the channels, no matter how much are used, they will always start sample-aligned. SyncAlign can also compensate the time differences in record while play mode for a simultaneous start of record and playback.
  • Track Marker Support (TMS)
    TMS is a new solution from RME to allow the transfer of track IDs from CD and start IDs from DAT directly into the PC and into the recording software. The method used is part of our DIGICheck technology and free to software companies. TMS is currently supported by Samplitude (since version 5.21) and WaveLab (version 3.0.)
  • Zero Latency Monitoring
    ZLM brings real tape machine feeling to the PC. Each tape machine directly passes the input signal to the output when starting a record. On the PC the monitoring is handled by software, which leads to a big delay (latency) between the signal at the input and the output of the hardware. ZLM works without any delay and fully automatically. At Punch-in the corresponding track is switched into bypass directly in the hardware, at Punch-out it switches back to playback. Thus the PC behaves exactly like a 'normal' tape machine. ZLM is already available with SEK'D's Samplitude Studio and 2496. ZLM is also available in ASIO 2.0 as ASIO Direct Monitoring.
