1. Introduction
DIGI32 PRO allows the recording of digital audio from CD, DAT, sampler or other digital
sources directly into your computer. The installation is made very simple, even for the inexperi-
enced user, thanks to the most up to date Plug & Play technology. The support of up to 24 bit
audio resolution and up to 96 kHz sample rate puts DIGI32 PRO at the top of the range of
interface cards available to date. Drivers for Windows 95™, Windows NT™and MacOS™allow a
problem-free, comfortable and powerful usage on computer systems with PCI bus technology.
Our Hi-Performance philosophy guarantees full system performance in all possible functions not
carried out by the driver (and therefore from the computer´s CPU) but carried out by the
DIGI32 PRO hardware.

• 20 bit 3 bytes MSB (stereo 6 bytes)
• 20 bit 4 bytes MSB (stereo 8 bytes) (*)
• 24 bit 3 bytes (stereo 6 bytes)
• 24 bit 4 bytes MSB (stereo 8 bytes) (*)
• 32 bit 4 bytes (stereo 8 bytes) (*)
* The indicated modes are directly supported by the hardware and therefore work in 32 bit hi-
speed transfer mode. The other modes (so called 'packed byte' formats) are queued up to 32 bit
data packets by special copy routines in the driver. These routines are written in Assembler,
causing no measureable system load. The supported modes with other Operating Systems than
Windows 95/98™and NT™depend on the OS and/or the corresponding drivers.
6. Hardware Installation
Important: Switch off the computer and remove the power cable from the power supply before
fitting the DIGI32 PRO. Inserting and removing the card when the computer is in operation
will more than likely lead to irreparable damage to the mainboard!
1. Disconnect the power cable and all other cables from the computer
2. Remove the PC housing; further information on how to do this can be obtained from your
computer´s instruction manual
3. Neutralize the static build up by touching the PC metal-chassis before unpacking the
DIGI32 PRO from the protective bag.
4. Insert DIGI32 PRO into a free PCI slot, press and fasten the screws.
5. Re-place the PC housing and tighten the screws.
6. Re-connect the power cable and all other cables/connections.

User's Guide DIGI32 PRO © RME 5
7. Software Installation
7.1 Windows 95™
After fitting the card (see 6. Hardware Installation) and switching on the computer, Windows 95™
discovers a new hardware component and starts the assistent for device installation. Insert the
RME Driver CD into your CDROM drive, and follow the instructions prompted on the screen.
Windows 95™will now install the DIGI32 PRO driver and reports that it is an audio device.
After that it is ready to use.
Due to a bug in Windows 95 OSR2 the path to the CDROM drive has to be typed in again
during the copy process.
7.2 Windows NT™
Because Windows NT™4.0 has not yet been supplied with a hardware recognition (Device Ma-
nager), the drivers must be installed by hand. This is very easy to do, as thanks to Plug & Play
IRQ (interrupt) and memory area are already defined.
After fitting the card (see 6. Hardware Installation), switching on the computer and completed
boot of Windows NT™insert the RME driver CD into your CDROM drive and add new devices by
using >Settings/Control Panel/Multimedia/Devices/Audio Devices/Add<. Change to the CD's
directory \nt\nt32. Windows NT™will now install the drivers and registers them as audio devices.
Finally DIGI32 PRO's Settings dialog shows up.
To finish the installation you MUST now press the 'Apply' button once! As long as 'Apply' is not
pressed at least one time the driver installation is incomplete, there is no display of the sample
rate and of the slot number. When installing more than one card 'Apply' has to be pressed for
each card once.
After clicking 'Apply' the driver is added to the registry, and the card is ready to be used.
7.3 Power PC (MacOS™)
Working with various software on the Mac requires registering the card in the Sound Manager.
But the Sound Manager does not support more than 16 bit and 48 kHz. A complete support of all
the outstanding features of the DIGI32 PRO is currently only available when using our
ASIO driver with related software. This allows up to 24 bit and up to 96 kHz at a very low latency.
The driver file is located in the RME Driver-CD's directory \Mac and includes an installation pro-
gram. After fitting the card (see 6. Hardware Installation), switching on the computer and boot of
MacOS™first decompress the file (Stuffit format). Then start the installer and follow the instructi-
ons on the screen. At last the file 'Digi32 ASIO' which is located in the new 'RME' folder must be
copied into the 'ASIO Drivers' folder of the corresponding ASIO software.
It is not possible to use the DIGI32 PRO with the control panel 'Monitors and Sound'! This
is a restriction of the operating system. That's why Apple still ships the old control panel 'So-
und', available in the Apple Extras Folder. Drag it to the system folder before installing our card
and drivers to gain complete access to the DIGI32 PRO as expected.
More informations can be found on our Mac web page (or on the Driver-CD).

8. Operation and Usage
8.1 Connections
The DIGI32 PRO has 3 external and 1 internal input and output (contact pins on the board).
The internal input serves as a connection with an internal CD-ROM drive when this is supplied
with a digital audio output. Advantage: the built in CD-ROM drive is sufficiant for digital recording
and the need for external cabling does not arise.
The actual input is activated by the registercard ‘Settings’, available through >Settings/Control
Panel/System/Device Manager/DIGI32 PRO/Properties/Settings<. DIGI32 PRO accepts all
common digital sources as well as SPDIF and AES/EBU. Channel Status
(Consumer/Professional) and copy protection will be ignored.
Connecting Chinch
(SPDIF) or XLR
(AES/EBU) devices is
done through the supplied
cable adapter. DIGI32
PRO’s ground-free de-
sign with transformers for
inputs and outputs offers
a problem-free connection
of all devices along with
perfect hum rejection.
All outputs are driven parallel, therefore you get an identical signal. In the simplest situation,
connect 3 devices at the outputs and use the card as splitter (distribution 1 to 3).
The stereo jack provides a hi-quality analog monitor output, driven directly from the digital out-
puts. A low impedance driver stage even allows the connection of stereo headphones, the
‘Level’ switch can be used to change the output level.
8.2 Playback
DIGI32 PRO sends digital audio data automatically in the parameters of the wavefile, when
the selected format is supported. Otherwise the supplying software will report an error.
Firstly the card has to be set as transmitting device in the software in use, look for Playback
Device, Device, Audiogerät etc, to be found under Options, Vorgaben or Preferences. Some
seldom found programs only use Windows' Prefered Playback Device. This setting can be
changed in >Control Panel/Multimedia/Audio<. As resolution for playback we recommend 24 bit,
because in this setting the full potential of the DIGI32 PRO is available. Drawbacks with the
16 bit operation do not arise.
'Step by Step' instructions showing the setup process of some well known programs can be
found in 'setup.htm' and 'setup2.htm' in the directory \rmeaudio.com\english\techinfo\ on the
RME driver CD.

User's Guide DIGI32 PRO © RME 7
The picture to the right
shows the smallest buf-
fer setting for a crackle-
free 24 bit operation in a
computer with 200 MHz.
More or larger buffers
produce an even higher
defence against distur-
bance, but also cause a
longer delay in playing
back the data. In case of
synchronized audio to
MIDI playback be sure to
activate the checkbox
'Get play position from
audio driver' when
available in your pro-
gram. Because the
DIGI32 PRO re-
ports the actual play
position correct (even in
record where this is nec-
cessary for chase lock sync) there will be no sync problems when working in a mixed audio/MIDI
environment even with higher buffer settings.
8.3 Record
After the DIGI32 PRO has been set up as recording device in the software being used at
the time, there are a few further points to note. Because the operating system cannot define
errors exactly, it may well be that you receive the same error message for very different types of
problems.
As opposed to soundcards which produce empty wave files (just noise) even without an input
signal, digital in/out cards must have a valid input signal to begin recording. The correct sample
frequency is also important. There is no valid input signal available when a DAT plays back a
tape which has been recorded at 48 kHz, and the recording software is set at 44,1 kHz.
Because of this peculiarity RME has given the DIGI32 PRO two unique features: an Error
LED for the active input in use and a visual display of the actual sample frequency. The Error
LED indicates wether a valid input signal is present. Whenever an error occurs (wrong input,
invalid data, signal delivering device delivers nothing) the LED will light red. As soon as a valid
input signal is present this light will go off.
The display of the sample frequency (see chapter 9, picture Properties) in the Device Manager
offers a similar function. If none of the standard frequencies like 32 kHz, 44,1 kHz or 96 kHz
come up then ‘Out Of Range’ will appear, and by an error detection ‘No Lock’.
Therefore configurating the software to perform a digital recording is child´s play. After choosing
the correct input DIGI32 PRO will show the actual sample frequency. You can now enter
this information into the corresponding dialog box of the recording program.
Additional DIGI32 PRO includes a safety function that checks the sample frequency. For
example feeding a signal with 48 kHz and trying to record with 44,1 kHz is not allowed. Otherwi-
se recordings with a wrong pitch would be the result.

User's Guide DIGI32 PRO © RME 8
The screenshot to the right shows an example
of a dialog box, in this case of the wave editor
WaveLab from Steinberg, which allowes the
use of 20 bit, 24 bit and up to 96 kHz with the
DIGI32 PRO. With this dialog box you set
the characteristics of the wave data to be re-
corded in detail.
The choice of bit resolution is optional as long
as it is supported by the hardware. You may
record only in 16 bit mode even with an input of
24 bits. Bits 17 to 24 are then ignored and the-
refore all signals 95 dB below Full Scale will be
lost without the chance of recalling them. On
the other hand recording in 24 bit from a 16 bit source brings no advantages but wastes pre-
cious memory space on the harddisk.
Normally the output of the card is switched off. Often it is helpful to monitor the input signal or
pass it on. For such cases the DIGI32 PRO is fitted with a monitor function, which can be
set in the Settings dialog of the DIGI32 PRO driver (Output/Automatic). Activating the re-
cording software using Pause or Play leads to passing the input signal direct to the output. In
some cases the record program itself handles the monitoring, the settings in 'Ouput' then won't
change anything.
8.4 Record while Play
DIGI32 PRO allows the playback of wave data during the recording of further wave data.
This feature, known as ‘Full Duplex’ or ‘Record while play‘, is unavoidable for multitrack harddisk
recording, but it must be supported by the recording software.
Full Duplex operation requires identical sample frequencies, same bit rate and same format
(mono/stereo) for the signal to be recorded and the signal to be played back!

9. Configurating the DIGI32 PRO
9.1 General
The hardware of the DIGI32 PRO includes a number of helpful options under all supported
operating systems, that allow to configure the behaviour of the card according to the actual
needs. Through the registercard ‘Settings’ you will gain access to:
• Selecting the input
• State of the output
• Channel Status of the outgoing signal
• Synchronisation behaviour
• Display of the input signal
The display of the actual input frequency is updated every 0,5 seconds. When choosing an input
with a signal including errors or without input signal the statement ‘No Lock’ appears, in case of
sample frequencies widely out of tune ‘Out of Range’ is shown. When an optical signal is
present while the coaxial input is active then you immediately see that there’s no valid signal
available. The changing / switching of the inputs happens right away and needs no further click
on OK. All parameters for the active input needed to start recording are found very quickly. With
this the tedious ‘trial and error’ to get a digital recording working becomes a thing of the past.
The three states of the output selected through the choicebox ‘Output’ are unavoidable functions
for daily use.
‘Automatic’ sets the normal mode where
the input signal reaches the output only
whilst recording. In this mode when star-
ting a recording feedback occurs very
often in studios with digital mixing desks.
‘Play only’ solves this problem by making
sure that the input signal is never passed
through to the output.
After selecting ‘Input’ the input signal
appears always at the output when play-
back is not active. DIGI32 saves a
continual recording standby mode and
can switch itself to monitoring without
active software. As the output options
operate immediately stepping through
the inputs gives a fast check of the in-
coming signals.
'AutoSync’ guarantees a fault-free functi-
on of the modes Record, Record while
Play and while using more than one card
(see chapter 10.2). In specific cases, like
a direct connection of the inputs and outputs of a DAT with the DIGI32 PRO, AutoSync
leads to a local feedback of the digital carrier. In such cases AutoSync can be deactivated to
avoid this local loop problem.
Specific information about the right choice of the Output Channel Status (Output Format Con-
sumer / Professional) can be found in chapter 11.

User's Guide DIGI32 PRO © RME 10
Changes to the settings should not be made during record or playback, as it might come to
disturbances, in some cases even to a crash. Please be aware that several programs won't stop
playback or record (technically do not close the device) even in Stop mode. Thus changing the
settings might not have any immediate effect. In general we recommend - if available - to disable
the option 'Audio active in background', and to enable 'Close Audio Device on Stop' or similar.
9.2 Windows 95™
DIGI32 PRO proves a fine example of integrating with Windows 95™'s device manager. But
accessing the DIGI32 inside the Device Manager is more complicated as it should be. To
shorten the laborious way to the registercard Settings a link is copied to the desktop
(C:\Windows\ Desktop), its icon to C:\Windows\. Using the shortcut Ctrl-Num2 (the number 2 on
the number block) or a double click on the board lets you jump straight to the Device Manager.
From there it's only a few clicks to 'Settings'. If you need continous access to 'Settings', simply
don't close it. With Ctrl-2 'Settings' gets into the foreground at any time.
9.3 Windows NT™
The official way to Settings in Windows NT™isn't easier as with Windows 95™. Because of this
the RME Driver CD comes with an icon and two programs in the directory \tools. Please copy
'digi32.ico' and 'digiconf.exe' in your Windows directory (propably C:\NT). Next make a link to
'digiconf.exe' using the icon and the shortcut Ctrl-Num2 (the number 2 on the number block).
Using the shortcut Ctrl-Num2 or a double click on the board lets you jump straight to Settings. If
the program 'digitray.exe' is started with a double click another DIGI32 icon will show up in
the systray of the taskbar. A click with the left mouse button will again open the Settings dialog,
the right mouse button ends this program. Tip: Copy 'digitray.exe' into the StartUp folder, so that
Settings is always in reach.
9.4 MacOS™
Use the Sound control panel, Sound Out, to activate DIGI32 PRO as playback device, and
set up the desired sample frequency for playback.
The Soundmanager will activate a software sample rate converter when the sample rate set up
in Sound Out does not meet the one of the played back file. For highest quality the sample rate
of the card has to be identical with that of the played back file!
10. Using more than one DIGI32 PRO
10.1 General
The Windows 95™/ NT™driver is able to communicate simultaneously with all the cards known
to the system. The driver marks them with different numbers after the device's name, like
‘DIGI32 PRO In (1)’.
G

User's Guide DIGI32 PRO © RME 11
10.2 Synchronisation
DIGI32 PRO works exclusively in slave mode when recording. The card continously sear-
ches for a valid input signal at the active input. As soon as this matches the actual sample fre-
quency the card switches from the internal reference (quarz) to the clock generated out of the
input signal (PLL). So starting a recording on-the-fly is possible (also anytime during playback
thanks to Full Duplex) without first having to synchronize the card to the input signal.
In order to connect more than one DIGI32 PRO to a digital mixing desk they must all get
the same clock(ed input signal). This is easy to achieve: just connect at least one input of
each card to one output of the mixing desk.
But the slave mode however does not allow 'local loop-back' operation. For example: you play
back a wave file, send it through a digital effect device and immediately send it back to the com-
puter. Despite Full Duplex this is not possible because in this looped mode the card as well as
the external device synchronize themselve to their own input. A master or clock reference is
missing. Help is obtained either by the insertion of a digital mixing desk or by using two
DIGI32 PRO where the transmitting card is to be used without (!) an input signal. Hint:
Simply set the input of this card to an unconnected one.
In most cases 'local loop-back' can be realized. A DAT used as A-D-A-Converter whose digital
output is connected to the input of the DIGI32 PRO also leads to a loop and a loss of the
digital carrier. But after deactivating 'AutoSync' such a loop requiring no clock master is possible
even with other devices, because the DAT is not working in Full Duplex mode.
More informations on this subject can be found in the HTML document 'sync.htm', located in the
directory \rmeaudio.com\english\techinfo on the RME Driver CD.
10.3 Varispeed
Thanks to the described AutoSync technology and a lightning fast PLL DIGI32 PRO is able
not only to operate with usual sample frequencies, but with every frequency in the range of 25
kHz to 105 kHz. The digital input serves as synchronisation source. Please note that at the start
of a record or playback a valid sample frequency (32 kHz, 44,1 kHz, 48 kHz, 64 kHz, 88,2 kHz,
96 kHz) has to be fed. When started the sample frequency can be pitched to whatever is nee-
ded, DIGI32 PRO will follow theses changes immediately.
G

User's Guide DIGI32 PRO © RME 12
11. Special Features of the Digital Output
Digital audio signals in SPDIF or AES/EBU format include the audio information and a header
(Channel Status), transfering further information. Wrong Channel Status Data lead to misfuncti-
on. The Channel Status from the input of the DIGI32 PRO is not used, instead a completely
new header for the output signal is created.
It is to be noted that an indication of used emphasis disappears in recording or monitor mode.
Recordings done with emphasis should always be played back setting the emphasis bit.
This can be done by activating ‘Emphasis’ in the settings dialog box. Changing this setting is
possible without stopping playback, and can be monitored at the analog output.
The outgoing status data of the DIGI32 PRO has, with regard to other digital appliances,
been optimized to the largest compatibility possible:
• 32 kHz, 44,1 kHz, 48 kHz according to the sample frequency
• Audio use
• No copyright, copy permitted
• Format Consumer or Professional
• Category General, generation not indicated
• 2-Channel, No emphasis or 50/15 µs
• Aux bits audio use
Most consumer products with optical or cinch inputs (SPDIF) accept only signals with 'Consu-
mer' indication!
12. Troubleshooting
In case the message box ‘New Hardware Component found’ does not appear, or the driver can´t
be installed under NT:
• Is the Error LED of the DIGI32 PRO lit when no cable is connected to the optical input?
If not, the card is either defect or not sitting properly in the slot.
When the card and the driver have been properly installed but no playback is possible:
• Check that the DIGI32 PRO appears correctly in the Device Manager.
• If the device DIGI32 PRO is marked with a yellow exclamation mark then either an ad-
dress conflict or an IRQ conflict is present.
• If no yellow exclamation mark is present check the registercard 'Resources'. For example if
the BIOS allocates a different IRQ for the PCI slot of the DIGI32 PRO as before while
Plug & Play is disabled, Windows reports an unknown configuration. This can be corrected
by activating 'Use automatic settings'.
• Check that the DIGI32 PRO has been set as ‘transmitting device’ in the software. Also
check the settings under >Settings/Control Panel/Multimedia/Advanced<. Here the DIGI32
PRO must appear as an audio device when it´s been correctly installed and can be set as
the preferred device under 'Audio'.
G
G

User's Guide DIGI32 PRO © RME 13
Playback works but recording doesn´t:
• Check that a valid input signal is at hand. In this case the Error LED on the hardware extin-
guishes, and the actual sample frequency is shown under 'Settings'.
• If you are sure that a valid signal is being sent but the LED is still red, then check the chosen
input.
• Check that the DIGI32 PRO is set as recording device under the software being used.
• Check that the setting of the sample frequency in the software (recording properties or simi-
lar) relates to the adjacent signal.
The recording or the playback is disturbed by crackling:
• Increase the quantity and size of the buffers in the software being used.
• Use a different cable (coaxial or optical) to cross-check them for defects.
The computer hangs after the first access on the DIGI32 PRO:
• If you are using a graphics board with S-3 chip 968 then a memory allocation error might be
the reason. Please change the used memory area with 'Resources', so that it is adressed
underneath the memory area of the graphics board (for example D0000000 - D0FFFFFF).
More informations on this subject can be found in the document 'install.htm', located in the
directory \rmeaudio.com\english\techinfo on the RME Driver CD.
13. Installation Problems with older PC
Older models without Plug & Play compati-
ble mainboards often present some pro-
blems. In such cases the configuration of
the IRQ in the BIOS and the configuration of
the memory area in Windows must be done
by hand. In the Device Manager (Settings
/Control Panel/System) the DIGI32
PRO usually appears in the category 'So-
und, video and game controllers’.
A double click on the DIGI32 PRO
calls up the properties dialog, and after se-
lecting 'Resources' the interrupt and memo-
ry area shows up. After disabling 'Use au-
tomatic settings' the memory area can be
changed, the bottom part of the dialog box
showing whether a conflict with another
device will result out of the newly selected
value. The IRQs cannot be changed becau-
se Windows 95™strictly uses the settings
from the mainboard´s BIOS.
