just their own output levels. See
About the Interaction between
OPTIMOD-PC’s Input Mixers and Your PC’s Built-In Mixer
on page 2-26.
Note also that if the sample rate of the source material is different from
48 kHz (OPTIMOD-PC’s native sample rate), the operating system will ap-
ply the appropriate sample rate conversion.
Applying OPTIMOD-PC’s Output to WAVE Devices
OPTIMOD-PC’s WAVE output looks like the
output of a sound card to the host computer.
Any application that can receive the output of
a standard Windows WAVE device can use this
output. Most such applications have a menu
item that lets you select the particular WAVE
device from which they are receiving input; se-
lect “OPTIMOD-PC.” Once you have done this,
you can set the drive level to the application
via the WAVE output attenuator in the
OPTIMOD-PC I/O Mixer. You can select the
source that drives the application (PC WAVE
output, output of Direct Mixer, output of
OPTIMOD-PC pre-limiter, or output of
OPTIMOD-PC) via the drop-down selector lo-
cated above this attenuator.
For example, the figure shows Adobe Audition
2.0 Audio Hardware Setup.
If you have more than one OPTIMOD-PC card installed, these will be known to Win-
dows as “Orban Optimod 1100,” “Orban Optimod 1100 (2),” “Orban Optimod 1100
(3),” etc., in the order that they are installed in the PCI slots in your computer. You
may have to experiment in order to determine which OPTIMOD-PC card is associated
with a given name. Once you determine the association, it will not change unless
you remove or add cards.
Please note that Windows cannot read the serial number of an
OPTIMOD-PC to identify it uniquely.
Also, note that if you remove an OPTIMOD-PC card from your computer
(so that there are fewer cards), Windows may assign different names to
the remaining OPTIMOD-PC cards. However, if you replace one
OPTIMOD-PC with another one in the same PCI slot, the new card will
still have the same Windows name as the old card if the total number of
OPTIMOD-PC cards is the same as before.
This naming limitation does not apply to the Orban Control application,
which can identify installed OPTIMOD-PC cards by their serial numbers.
The naming limitation applies
only
to Windows applications that expect
to receive streams from WAVE devices.
This is mainly relevant to users running multiple instances of a streaming
encoder program like Orban Opticodec-PC, Real/Helix Producer or Win-
dows Media Encoder. Typically, each instance of the streaming program
is connected to a separately named OPTIMOD-PC WAVE device. For ex-
