INSTALLATION ORBAN MODEL 1101
Power Ground
Ground the chassis of the computer housing OPTIMOD-PC through the third wire in
the power cord. Proper grounding techniques never leave equipment chassis uncon-
nected to power/earth ground. A proper power ground is essential to safe opera-
tion. Lifting a chassis from power ground creates a potential safety hazard. Ground
loop and hum problems should never be solved by disconnecting or lifting power
grounds.
Audio ground loop or hum problems are often solved by proper shield connections
and/or by making sure that analog inputs and outputs are correctly balanced. The
analog inputs and outputs of OPTIMOD-PC are balanced, which facilitates maintain-
ing balanced connections through a system. Refer to the previous section,
Ground-
ing , for details.
Setup: The OPTIMOD-PC Control Application
Once you have connected the Orban Control application to an OPTIMOD-PC card,
the software allows you to control the card as if it were a dedicated hardware proc-
essor like an Orban OPTIMOD. The Control application displays gain reduction me-
ters, as well as controls that allow you to edit the sound of the factory presets to
your liking. Section 3 of this manual explains these sound editing controls in detail.
This section of the manual tells you how to set up the input and output controls of
an OPTIMOD-PC card, with emphasis on connections that use OPTIMOD-PC’s exter-
nal analog or digital inputs and outputs to emulate a hardware audio processor.
Starting on page 2-44, we provide additional instructions for users who want to
connect OPTIMOD-PC’s inputs and outputs to other programs (like streaming encod-
ers) through the Windows WAVE multimedia mechanism inside your computer. Even
if you are only using OPTIMOD-PC’s WAVE input and output, you should still work
through all of the instructions below, ignoring those that apply only to OPTIMOD-
PC’s hardware I/O.
1. From the Tools menu, bring up the I/O Mixer.
The I/O Mixer is a tabbed control panel that allows you to configure many global
OPTIMOD-PC parameters, like input and output levels. If you are familiar with
Orban’s hardware processors (like our OPTIMOD-PC 6200/6200S), you will recog-
nize many functions as being similar to those found in OPTIMOD-PC’s

menu. However, the OPTIMOD-PC I/O Mixer is more powerful.
2. Select the card you are setting up.
A) From the Connect menu on the Control application, select the card you are
setting up by connecting to it.
If you have only one card installed in your ma-
chine and you open the OPTIMOD-PC applica-
application from the agent, you do not need
