Connect the Devices
1. Connect each of the video display devices to the VEEMUX-A using 3CEXT-xx or 4CEXT-xx cables. The groups of terminals
are labeled OUTPUT1-4. Use BNC to RCA adapters (as shown in figure 3) to connect the BNC cables to the devices.
Connectors on the VEEMUX-A are labeled green (Y), blue (Pb) and red (Pr) to correspond with the colors on the BNC cables.
2. Connect each digital audio device to a OUTPUT connector labeled "DIGITAL". If the audio device is a stereo type device,
connect it an OUTPUT terminal block. Connections to the terminal block should be made as shown in Fig. 2 for devices that are
compatible with balanced or unbalanced stereo audio.
Note: Stereo audio devices can not be used to listen to digital audio sources, and digital audio devices can not be used
to listen to stereo audio sources.
