With the exception of input 1 and 2 S-video, all video input and output
connections to the scaler are made with female BNC
connectors. Some types of video output devices do
not have BNC video output connectors. For these
cases, a suitable cable or connector adapter is
necessary between the device output connector and
the BNC input connector of the switcher. The
Extron part number for the RCA-to-BNC adapter
is 10-264-01.

Input connections

both, the scaler will not accept either signal.

component video, S-video, or composite video to these female BNC
connectors. Figure 2-3 shows how to connect the various video formats.

audio input to these pairs (left and right) of RCA connectors. Computer
sound cards and other devices with a 3.5 mm mini output connector can be
connected using an optional Extron IN9107 3.5 mm stereo mini male to (2)
