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.
