INTRODUCTION ORBAN MODEL 1101
•
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. The 1101 contains two logical sound cards, so there are two
WAVE inputs and two WAVE outputs.
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 outputs follow the professional AES3 hardware
standard regarding impedances and levels, although their data streams
can also be configured to follow the consumer S/PDIF standard. In most
practical situations, AES3 and S/PDIF are interchangeable and can be in-
teroperated 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 S/PDIF 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.
If you have ordered the optional 1101/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.
Analog Left/Right Input/Output
The left and right analog inputs are on XLR-type female connectors on the umbilical
cable. Input impedance is greater than 10k
Ω
; balanced and floating. Inputs can ac-
commodate up to +20dBu (0dBu = 0.775Vrms).
The left and right analog outputs are on XLR-type male connectors on the umbilical
cable. Output impedance is 50
Ω
, balanced and floating.
