• 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.
  • Bitclock PLL
    The DIGI96 series always uses RME's bitclock PLL (already in its second generation, with improved HF noise suppression), whether it is synchronized via Optical In or via word clock. Thanks to the high resolution, this remarkable circuit is capable of following the entire range of an ADAT recorder's Varipitch without losing a single sample. Compare this with the much coarser wordclock PLL, where any rapid changes in sample frequency can cause several false reads, before the next impulse finally arrives, letting the PLL track the current sample frequency. This behavior leads to dropouts and clicks.
  • 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.
  • Enhanced ZLM®
    The direct pass through of digital data requires the input and output to carry the same AND synchronous sample frequency. In most cases a monitoring is only possible in clock mode slave (AutoSync.) Enhanced ZLM® removes those restrictions and allows a monitoring of the input signal completely independent from clock mode and sample frequency, even with totally different data 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.
  • Latency Fast Change
    RME's ASIO drivers have become reference. They were the first and only (beginning with the Hammerfall, followed by the DIGI96 series) to allow a change of the latency while under operation (on the fly.) No manual reset, no re-boot - simply continue when using Cubase.
  • Mixed Mode
    Due to the complete separation of record and playback circuits both can be used in any possible format, independent of each other. So a record of up to 8 channels using ADAT® optical at simultaneous playback of 2 channels using SPDIF and vice versa is possible. Thanks to the incredible PLL and clock control of the DIGI96 series it's even possible to let S/PDIF synchronize on ADAT and vice versa! This is also true for double/half sample rates, for example a playback in 96 kHz using SPDIF can be synced from an 48 kHz ADAT input signal.
  • SyncAlign®
    SyncAlign includes several methods and techniques to guarantee absolute data alignment with regard to time and channels. No RME digital audio card will ever swap channels, not in stereo nor in multi channel mode, 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. When the record while play mode is activated, the corresponding software first starts record and then playback (or playback then record.) SyncAlign can compensate the time difference so that an exact simultaneous start of record and playback in the record while play mode is guaranteed. In asynchronous mode (different programs use different stereo devices of one card) this part of SyncAlign is automatically deactivated.
  • 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®)
    ZLM brings real tape machine feeling to the PC. Each cassette recorder and tape machine passes the input signal of the track in record to the output when record starts. On the PC such a kind of track dependent pass through wasn't available. Often all channels are put in monitoring or pass through mode all together. Or the monitoring is handled by the software, resulting in a big delay (latency) between the signal at the input and the output. After all the pass through mode is activated at record, not at Punch-in. ZLM now solves all these problems with a simple technique. 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 SEKD's Samplitude and Sequoia, and SAWStudio. It is included as ASIO Direct Monitoring in ASIO 2.0.
