3 Overview

The VM-30AV and/or VM-30AVB 1:3 Audio/Video DA are high performance 1:3 distribution amplifiers for video and stereo audio signals. The VM-30AV and/or VM-30AVB accept one input ^1 and distribute the signal to 3 identical outputs. Video signals transmit via:

• RCA connectors on the VM-30AV
• BNC connectors on the VM-30AVB

Both the VM-30AV and/or VM-30AVB include:

• RCA connectors for stereo audio signals
- Extra wide video bandwidth of 430MHz that allows for high-resolution data/video signals, SDI (serial digital) video and other specialized signals
• An audio level control knob
- Front panel cable EQ (equalization) and video level trimmer controls

Achieving the best performance means:

• Connecting 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)
• Avoiding interference from neighboring electrical appliances that may adversely influence signal quality and positioning your Kramer VM-30AV or VM-30AVB in a location free from moisture and away from excessive sunlight and dust

Caution - No operator-serviceable parts inside unit.

Warning - Use only the Kramer Electronics input power wall adapter that is provided with this unit ^2 .

Warning – Disconnect power and unplug unit from wall before installing or removing device or servicing unit.

5 Using Your Audio/Video DA

Section 5.1 describes how to connect a VM-30AV/B ^2 . Section 5.2 describes how to configure a 1:3 Audio/Video DA for component video (YUV) or RGB. You can also use the VM-30AV/B, with its very high frequency, to process SDI (serial digital interface) video.

5.1 Connecting your VM-30AV/B

To connect ^3 the VM-30AV/B 1:3 Audio/Video DA, as the example in Figure 3 illustrates, do the following:

1. Connect a composite video source (for example, a composite video player) to the VIDEO INPUT connector and to the left and right AUDIO INPUT RCA connectors.

2. Connect ^5 the 3 VIDEO OUT connectors and the left and right AUDIO OUT RCA connectors to the audio video acceptors (for example, composite video recorders).

3. Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity (not shown in Figure 3).

4. Adjust the audio level and the video EQ. and video level, as required.

5.2 Configuring a 1:3 Audio/Video DA for Component (YUV) or RGB

To configure a 1:3 Audio/Video DA for component (YUV) or RGB by combining three VM-30AV/B units, as illustrated in the example in Figure 4, do the following.

Connect ^1 the 1:3 Audio/Video DA for component (YUV) or RGB, as follows:

1. Connect the RGB source, by connecting:

2. The R cable to the first unit’s INPUT connector
   The G cable to the second unit's INPUT connector
   The B cable to the third unit's INPUT connector

3. Connect the first RGB acceptor, by connecting the OUT 1 connector from the:

■ First unit to the R cable
■ Second unit to the G cable
- Third unit to the B cable

1. Connect the second RGB acceptor, by connecting the OUT 2 connect from the:

■ First unit to the R cable
■ Second unit to the G cable
- Third unit to the B cable

1. Connect the third RGB acceptor, by connecting the OUT 3 connector from the:

■ First unit to the R cable
■ Second unit to the G cable
- Third unit to the B cable

1. Connect the audio source and acceptors, as required.

2. On each VM-30AV/B unit, connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity.

3. Adjust the audio level and the video EQ. and video level, as required, on the front panel on the first VM-30AV/B unit. This adjusts the levels on the combined 3 VM-30AV/B units.
