DIGI32 needed only a short time to be accepted as THE digital I/O card on the market. The reasons for this are - besides many technical details - its unsurpassed reliability and the user friendly design of card and driver, coming along with absolute data integrity, minimal system load and tremendous performance.

When users demand a digital system to play back the data identical to those recorded before - 1:1 in every situation - this should be nothing to be worth mentioning. Unfortunately it is. 'Digital' alone does not guarantee such a behavior. Look around which manufacturer ever claimed his card to behave like this - you will find only us. DIGI32 is the result of an intensive development by hardware and software cracks, accompanied by detailed tests of home and professional users. This is the base of our success!
3 inputs switchable during operation
Routing to the output changeable during operation
Outputs optical / cinch work simultaneous (signal distribution possible)
Ignores copy protection
High sensitive input stage (< 0,2Vpp input level)
High bus transfer rate (> 120 MByte/s)
More than one card with only one driver useable
Inputs and outputs ground-free transformer coupled
Error LED for input signal
Low Jitter Design: < 3 ns in PLL mode (44,1 kHz, optical In)
AutoSync enables perfect recording in all modes
Sample aligned simultaneous start of record and playback in Record while Play mode
Very low system load through 32 Bit memory transfer and 128 kB fast SRAM
Automatic hardware self test when booting
Input optical (TOSLINK), coaxial (Cinch), internal (jumper)
Input format SPDIF (Consumer, Professional), with cable adapter AES / EBU
Output optical (TOSLINK), coaxial (Cinch)
Output format SPDIF (Consumer, Professional), with cable adapter AES / EBU

Using the 'Settings' tab in the device manager gives you full control over the DIGI32. 'Input' lets you change the actual input. 'Sample Frequency' tells you which sample rate the signal at the chosen input has (32 kHz, 44,1 kHz, 48 kHz, Out of Range, No Lock.) 'Output' controls the monitoring while recording. 'Automatic' switches the input signal to the output only in record mode, 'Input' all the time except something is played back, and 'Play only' helps you to avoid feedbacks as the input signal will never be passed to the output.

AutoSync allows a constant synchronization to the input signal. The format of the digital output is set up in 'Output Format' (surprise, surprise...) to professional or consumer standard. All options are available in real-time, without having to reboot or even to click OK!

Our unique Windows NT driver gives you the same options as the driver for Windows 95! There is only one driver supporting all cards of the DIGI32 series in every combination. This includes the DIGI32/8 with up to 8 channels, Full Duplex and up to 24 bit.

  • 8 bit 1 byte (stereo 2 bytes) (only Windows NT)
  • 16 bit 2 bytes (stereo 4 bytes) (works as 32 bit hi-speed transfer)
  • 20 bit 3 bytes MSB (stereo 6 bytes)
  • 24 bit 3 bytes (stereo 6 bytes)
  • 24 bit 4 bytes MSB (stereo 8 bytes) (works as 32 bit hi-speed transfer)
  • 32 bit 4 byte (stereo 8 bytes) (works as 32 bit hi-speed transfer)
  • AutoSync
    DIGI32 works exclusively in slave mode. With AutoSync activated it continuously searches for a valid input signal. 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. In case of 'local loop-back' operation (for example DAT) AutoSync leads to a loss of the digital carrier. For this special application AutoSync can be disabled.
  • SyncAlign
    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.
  • SuperFast
    As a PCI bus card DIGI32 of course works in 32 bit mode. Instead of being snagged with slow DMA transfer, slow multiple 16 bit transfers using I/O addresses, non-linear memory transfer, or the non-usage of an IRQ (an attempt to get rid of resource problems at the cost of performance and data integrity) DIGI32 uses a linear memory transfer with the full copy speed of modern PC systems. 32 bit data pass the CPU in one cycle, being transferred to the hardware with PCI-bursts. The software is able to send its data without interruption. The effective system load is almost zero, which can be shown easily when using more than one DIGI32 in one system.
  • Hi-Performance
    Normally the designer of 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 the hardware, the PC and the software. Usually a large driver is needed to correct, map or translate all these things. But all actions of the driver are also actions of the CPU, ending in a high system load. DIGI32 is different. DIGI32 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 In/Out card should work and behave. The driver of the DIGI32 does not result in any slowing down the data transfer, because it has nothing else to do than to configure the user's options.
  • Hardware Self test
    When loading the driver (while booting Windows) DIGI32 performs a hardware self test. This test was originally only 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. Therefore you can always be sure when working with Digi32 that all bits are fully functional. In case of an error a message is displayed.
