About Inputs and
Outputs The exact function of Io
LD
or Io
LA
inputs and outputs depend on the operational
mode at a given time. In the capture mode, inputs are selected by Final Cut Pro’s
Audio Video Settings menus (or Easy Setups ). While capturing, the selected inputs
are mirrored at the Io panel’s outputs. When not in the capture mode, the outputs
change to reflect the output of Final Cut Pro. In all cases, all of the panel’s outputs
are active all the time. In other words, the same output video appears
simultaneously on all the output connectors the panel has. For example, the Io
LD
has simultaneous SDI output at its “SDI Out” connectors and Component or
Composite at its “A/V Monitor Out” connector. The Io
LA
has simultaneous
Composite, S-Video, and Component at its respective output connectors. This
method of operation allows simultaneous connection to VTRs and monitoring
facilities.
About BNC
Connectors Although most video professionals are used to BNC connectors, you may not
have seen them if you’ve been using primarily desktop video equipment. BNC
connectors ensure a positive connection by the act of locking the connectors
together via pins in one connector that fit into slots in the corresponding
connector.
To make a BNC connection, slide the cable connector over the connector on the
Io rear panel and then when seated, rotate the barrel of the cable connector 90˚
clockwise until the connectors are locked together. When properly locked, the
cable cannot accidentally be pulled out.
