The "video sync signals" of input position "1" are used by the VS-4x4YCas the basic reference for the timing of the vertical interval switching.
Back Panel:
Video Inputs
A variety of Super-Video / Composite input sources may be used such as videocassette recorders and cameras.
Audio Inputs
Up to four stereo-audio input sources can be connected to the VS-4x4YC. Audio sources can be the audio section of the video equipment used, or another audio source such as a tape recorder.
Video Outputs
Up to four super-Video / composite output acceptors can be hooked up to these connectors. A variety of acceptors may be utilized such as videocassette recorders or video monitors.
Audio Outputs
Up to four stereo-audio acceptors can be hooked up to these connectors. Audio acceptors may be the audio section of videocassette recorders, tape recorders or audio amplifiers.
The VS-4x4YCmay be utilized for die duplication, switching and editing of just stereo-audio sources. In this situation, you would utilize the audio outputs only.
AC Power Socket
Connect the appropriate cable to the AC power socket and plug it into a proper AC receptacle. (117 Volts AC, U.S.A.: 230 Volts AC, Europe.)
RS-232 Connector Socket
This socket connects via an appropriate adapter, or, as illustrated in the figure at the end of this manual to a PC serial port for RS-232 controlled switching.
9.INSTALLATION
9.1Rack Mounting
The VS-4x4YCmay be rack mounted in a standard 19” (1U) EIA rack assembly and includes rack “ears” at the ends of the front panel. The device does not require any specific spacing above or below the unit for ventilation. To rack mount the matrix, simply place the unit’s rack ears against the rack rails of the rack, and insert standard screws through each of the four corner holes in the rack ears.
10.CONNECTING TO VIDEO DEVICES
Video sources (such as cameras and VCRs) and output devices (such as monitors, projectors or recorders) may be connected to the switcher through the connectors located on the back of the unit. Please keep in mind that the input signal format must match that of the output signal format. (Example: If the input is composite video, then the output is composite video.) For signal formats that use more than one interconnecting cable between devices, the cables should be of equal length.
11.CONNECTING TO AUDIO DEVICES
Audio sources and output devices (such as amplifiers or recorders) may be connected to the VS-4x4YCswitcher through the RCA type connectors located on the back of the unit. The VS-4x4YCsupports unbalanced stereo audio signal types.
