• Computer RGB or component video distribution

Getting Started

We recommend that you:

• Unpack the equipment carefully and save the original box and packaging materials for possible future shipment
• Review the contents of this user manual

Go to http://nww.kramerelectronics.com/support/product downloads. asp to check for up-to-date user manuals, and application programs, and to check if firmware upgrades are available (where appropriate).

Achieving the Best Performance

To achieve the best performance:

• Use only good quality connection cables (we recommend Kramer high-performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low-quality cables)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoid interference from neighboring electrical appliances that may adversely influence signal quality
• Position your Kramer VM-1021N away from moisture, excessive sunlight, and dust

This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

Safety Instructions

• Caution: There are no operator-serviceable parts inside the unit
• Warning: Use only the power cord that is supplied with the unit
• Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by qualified personnel only
• Warning: Disconnect the power and unplug the unit from the wall before installing

Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility. For details of Kramer’s recycling arrangements in your particular country go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

Overview

The VM-1021N is a high-performance distribution amplifier for composite or SDI video signals. It provides controls to compensate for signal losses inherent in long cable runs.
The VM-1021N is a full broadcast, state-of-the-art, 1:20 video distribution amplifier designed for studio and other demanding applications. The unit splits a single input source into twenty identical outputs with no discernible signal degradation. The outputs are divided into 4 sets of five each, where each set may be individually trimmed (level and EQ) for maximal flexibility. The machine may be used to distribute analog or SD-SDI video signals, composite or single components.
The unit features:

• High bandwidth of 350MHz (-3dB)
• Grouped level (gain) and EQ (peaking) controls
• Looping inputs
• Selectable input signal termination
• DC coupling
• Standard 19” rack mount size of 1U

Installing in a Rack

This section provides instructions for rack mounting the unit.
Before installing in a rack, be sure that the environment is within the recommended range:

CAUTION!

When installing on a 19″ rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi-unit rack assembly may exceed the room ambient temperature.
2. Once the rack is mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

2. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.
   Note:

   • In some models, the front panel may feature built-in rack ears
   • Detachable rack ears can be removed for desktop use
   • Always mount the machine in the rack before you attach any cables or connect the machine to the power
   • If you are using a Kramer rack adapter kit (for a machine that is not 19″), see the Rack Adapters user manual for installation instructions available from our Web site

Connecting the VM-1021N

Always switch off the power to each device before connecting it to your VM- 1021N. After connecting your VM-1021N, connect its power and then switch on the power to each device.

To connect the VM-1021N as illustrated in the example in Figure 3:

1. Connect a video source to the INPUT BNC connector (for example, a composite video player).
2. Connect the OUT SET BNC connectors to up to 20 video acceptors, 4 sets of 5 devices (for example, composite video displays with speakers).
3. Adjust the equalization (EQ) and level (LEVEL) for each of the 4 sets of 5 devices as needed.

VM-1021N – Connecting the VM-1021N

Note:

• Terminate unused inputs to 75Ω, and terminate active inputs at the connecting source
• The output signal format must match the input signal format (for example, if the input is composite, the output is composite)
• All signal cables to each device should be of equal length (for example, the R,G,B cables between a camera and the amplifier should be of equal length)
