INSTALLATION
Connect the Sources
1. Turn OFF power to all video sources (inputs) that will be connected to the VEEMUX-A before connecting or
disconnecting any cables.
2. Connect each video source to the VEEMUX-A using 4CEXT-xx BNC cables. The groups of terminals are labeled INPUT1-8.
and colored cables attach to terminals as follows: green (Y), blue (Pb) and red (Pr). If necessary, use BNC to RCA adapters to
connect the cables to the video sources (see Fig. 1). If the cables used do not have BNC connectors on them but have RCA
connectors instead, use an RCA-to-BNC adapter on each to connect to the VEEMUX-A.

3. Audio connections can either be digital or analog (stereo). A connector marked "DIGITAL" is provided in each INPUT group
for digital audio cable connection. A terminal block for the connection of a line-level stereo audio cable is located below each
connector group. (See Fig. 1) The VEEMUX-A supports balanced line-level audio signals, as well as unbalanced. Figure 2
shows the proper cable connection method for each.
