AVoption & AVoption XL Guide18
Connecting a VTR
A VTR can be used to provide video input and to
record video output from AVoption. In most sit-
uations, there are three connections you need to
make:
• Connect a black burst or house sync output to
a video input on your VTR (preferably a refer-
ence video input).
• Connect the ABVB cable’s CV IN and/or Com-
ponent IN connectors to the corresponding
outputs on your VTR.
• Connect the ABVB cable’s CV OUT and/or
Component OUT connectors to the corre-
sponding inputs on your VTR.
– or –
• Connect the ABVB cable’s CV OUT and/or
Component OUT connectors to the corre-
sponding input on an NTSC or PAL video
monitor, then connect the outputs from this
monitor to corresponding inputs on your
VTR.
Connecting an External Video
Reference Monitor
To connect an external NTSC or PAL video ref-
erence monitor, use the ABVB cable’s Compos-
ite or Component Video outputs.
Centralized Video Switching and
Routing
Many professional facilities have centralized
video switching and routing systems. These sys-
tems can be used to route AVoption’s inputs and
outputs to flexible input sources and output des-
tinations.
Configuring AVoption with a
Single VGA Monitor
If you plan to run your Pro Tools AVoption sys-
tem with only one VGA monitor, you will need
to connect it to the Macintosh video card and
designate it as the system startup monitor.
If the ABVB VGA output has defaulted to being
the system startup monitor, you will need to
perform the following procedure.
To set the VGA monitor as the startup monitor:
1 Connect your monitor temporarily to the
ABVB VGA output.
2 Choose Monitors & Sound Control Panel >
Identify Monitors.
3 Drag the Menu Bar across the top of the mon-
itor icon from the ABVB monitor icon to the
Macintosh monitor icon.
4 Drag the Macintosh icon from the middle of
the ABVB monitor icon to the Macintosh moni-
tor icon.
5 Restart you computer, with your VGA moni-
tor connected to your Macintosh VGA output.
The monitor will now appear as the system star-
tup monitor.
Note that the steps above may be necessary
when you first install AVoption, as well as after
any time you zap the P RAM of your computer.
