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

This section describes what to do before installing on a rack and how to rack

mount.

Connecting the VM-5DS

6 Connecting the VM-5DS

To connect the VM-5DS, as the example in Figure 3 shows, do the following

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.
