KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The VM-5DS is a distribution amplifier for composite video and stereo audio
signals. It will take one composite video and stereo audio input, provide
correct buffering and isolation and distributes the signal to five identical
video and audio outputs plus one scaled output.
In particular, the VM-5DS features:
Has a high bandwidth of 360MHz, ensuring transparent performance
even in the most critical applications
Scaled graphics output resolutions: VGA (640x480), SVGA (800x600),
XGA (1024x768), or WXGA (1366x768)
Looping inputs, buttons for termination and video AC/DC coupling
Audio level control (independently for the left and right levels)
Video level (gain) and EQ. (Peaking) control
Is housed in a 19" 1U rack-mountable enclosure and is fed from a
90-240 VAC universal switching power supply
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and
position your VM-5DS away from moisture, excessive sunlight and dust

Connecting the VM-5DS
6 Connecting the VM-5DS
To connect the VM-5DS, as the example in Figure 3 shows, do the following1:
1. Connect a composite video source (for example, a composite video
player) to the VIDEO INPUT BNC connector and the AUDIO IN R and
L RCA connectors.
2. Connect the VIDEO OUT 1 BNC connector and the AUDIO OUT 1 R
and L RCA connectors to a composite video acceptor (for example, a
composite video recorder).
3. Connect the VIDEO OUT 5 BNC connector to a composite video
acceptor (for example, a video display).
4. Connect the SCALER OUT HD15 connector to a VGA acceptor (for
example, an LCD display).
5. Connect the power cord to the mains electricity.
