 DIGI32
PRO is the ultimate solution for transfer and playback of soundfiles.
The card works exactly like a DIGI32 with all its advantages, giving you a
perfect 2-channel digital in/out solution. Additional it supports the sample
frequencies 64 kHz, 88,2 kHz and 96 kHz. But DIGI32 PRO is not only
a good investment in tomorrow's technology. Many programs already support
sample frequencies up to 96 kHz. For example HpW's
Pro Generatorallows you to handle
more than 40 kHz analog, and programs like WaveLab and Samplitude also support
sample rates above 48 kHz.
The usage of such high sample rates requires a special DA-converter. DIGI32
PRO uses a hi-grade 20 bit DAC from AKM, that is able to convert up to
96 kHz (giving you an analog bandwidth of more than 40 kHz.) And there is
more: Simply activate the Emphasis bit on the digital output by selecting
it in the settings box, and listen to the result! DIGI32 PRO immediately
corrects the Channel Status of the digital output and the frequency response
at the analog output. Although built
in a PC the noise is very low. Due to a proper layout, double voltage regulation
and special RF filter the dynamic range is greater than 92 dB (RMS unweighted.)
No doubt: DIGI32 PRO is the new professional standard!

 Using
the 'Settings' tab in the device manager gives you full control over the
DIGI32 PRO. '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, 88,2 kHz, 96 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'. 'Emphasis' sets the Emphasis
bit on the digital outputs and forces the analog output to correct its frequency
response. 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 PRO with up to 3 cards, up to 96 kHz, Full Duplex and up
to 24 bit.

- AutoSync
DIGI32 PRO 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
any waitstate. The effective system load is almost zero, which can be shown
easily when using more than one DIGI32 PRO 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 PRO is
different. DIGI32 PRO 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 PRO
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 Selftest
When loading the driver (while booting Windows) DIGI32 PRO performs a hardware
selftest. 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 PRO that all bits are fully functional. In case of an error
a message is displayed.
