    CNX-PVID8x4 used without Crestron Room Solution Box In this system, the CNX-PVID8x4 has an incredible amount of flexibility with respect to making connections to all three types of video sources. For example, it is possible to have a composite source connected to INPUT 1, level 1 and an S-video source connected to INPUT 1, levels 2 and 3, simultaneously.

  • Page 8: Physical Description

    Professional Video Distribution Switch Physical Description The CNX-PVID8x4 is housed in a black enclosure with labeling on the front and rear panels. LEDs on the front of the unit indicate the unit's status. All connections are made to the back of the unit. Refer to the following illustrations.
