INTRODUCTION ORBAN MODEL 1100
The output sample rate can also be synchronized to OPTIMOD-PC’s inter-
nal clock.)
•
One set of analog left/right inputs and outputs.
The AES3 inputs and outputs and the analog output appear on a female
DB-25 connector on the rear of the card (see Figure 2-2 on page
2-5). Orban offers three variations of an “umbilical” cable that plugs into
the connector—one variation is terminated with XLR connectors, one is
terminated with RCA phono plugs, and one is unterminated.
•
Inputs and outputs passing through the computer’s PCI bus, using operating sys-
tem multimedia sound drivers, such as Microsoft Windows DirectSound WDM
WAVE drivers.
These inputs and outputs are controlled by the OPTIMOD-PC Mixer appli-
cation, which can be launched from the Tools menu on the OPTIMOD-PC
control application, and can also be remotely accessed.
Digital AES3 Left/Right Input/Output
The digital inputs and output follow the professional AES3 hardware standard re-
garding impedances and levels, although their data stream can also be configured
to follow the consumer SPDIF standard.
In most practical situations, AES3 and SPDIF are interchangeable and can
be interoperated with each other without difficulty; you usually do not
have to concern yourself with which standard you are using. Generally, if
the equipment to which you are connecting has pin jacks, set OPTIMOD-
PC to use the SPDIF standard. If the equipment has XLR-type connectors
or BNC connectors, set OPTIMOD-PC to use the AES3 standard.
OPTIMOD-PC incorporates an output sample rate converter that allows operation at
32, 44.1, 48, 88.1, or 96 kHz sample frequency. The inputs have sample rate convert-
ers that allow the input to accept any sample rate between 20 kHz and 96 kHz.
To ensure best control of peak modulation, operate the output at 48
kHz. This guarantees that the output samples are synchronous with the
peak-controlled samples produced by the processing.
If you have ordered the optional 1100/CBLXLR XLR-terminated cable assembly, then
the left/right digital inputs appear on two XLR-type female connectors on this cable.
The left/right digital output is on one XLR-type male connector on the cable. If a
given digital input is not being used to receive a digital audio input, it is available to
genlock OPTIMOD-PC’s output sample frequency to house sync, if required.
OPTIMOD-PC simultaneously accommodates WAVE, digital, and analog inputs and
outputs. You can mix all inputs into one signal that is applied to the processing. The
digital inputs can be asynchronous because both are applied to sample rate convert-
ers that lock them to OPTIMOD-PC’s internal 48 kHz sample frequency.
Level control of all inputs and outputs is via the OPTIMOD-PC Mixer application, in-
cluding remote access.
