1 Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been

providing a world of unique, creative, and affordable solutions to the vast range of

problems that confront the video, audio, presentation, and broadcasting

professional on a daily basis. In recent years, we have redesigned and upgraded

most of our line, making the best even better!

Our 1,000-plus different models now appear in 11 groups that are clearly defined

by function: GROUP 1: Distribution Amplifiers; GROUP 2: Switchers and Routers;

GROUP 3: Control Systems; GROUP 4: Format/Standards Converters; GROUP 5:

Range Extenders and Repeaters; GROUP 6: Specialty AV Products; GROUP 7:

Scan Converters and Scalers; GROUP 8: Cables and Connectors; GROUP 9:

Room Connectivity; GROUP 10: Accessories and Rack Adapters and GROUP 11:

Sierra Products.

Congratulations on purchasing your Kramer VM-1010, VM-1021, VN-1055 or

VM-54 distribution amplifier that is ideal for the following typical applications:

•Broadcast, production, or presentation systems requiring high-quality signal

distribution

•Schools, retail, sports bars, other point-of-sale and CCTV applications

•Computer RGB or component video distribution

2 VM-1010, VM-1021, VN-1055, VM-54 - Getting Started

2 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

•Use Kramer high-performance, high-resolution cables

•Use only the power cord that is supplied with this machine

Go to http://www.kramerelectronics.com to check for up-to-date

user manuals, application programs, and to check if firmware

upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection 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 product away from moisture, excessive sunlight and

dust

Caution: There are no operator serviceable parts inside the unit

Warning: Disconnect the power and unplug the unit from the wall

before installing

Your amplifier is pre-calibrated at the factory for

transparent operation. Re-tuning it can upset signal

transparency.

Do not attempt to adjust the LEVEL trimmers without

using accompanying standard calibrated oscilloscope

or waveform monitor!

This section provides instructions for rack mounting the 1U devices. 2U and 3U

devices use the same procedure with longer rack “ears” and additional screws.

This section describes the VM-1010 Programmable Video Distributor.

4.1 Overview

The VM−1010 is a highperformance distribution amplifier for composite video. It

can also be configured as a 1:5 distribution amplifier for sVideo (Y/C) signals and

has controls to compensate for signal losses inherent in long cable runs.

The VM−1010 is designed for studio and other demanding applications. It has two

looping video inputs, each splitting to 5 outputs. The user may select 2x1:5 or 1:10

operation via front panel control switches. Several VM-1010 units may be chained

through the looping inputs. Output signals are DC or AC coupled (user selectable)

for maximum flexibility.

The unit features:

•High bandwidth of 235MHz (3dB)

•Dual-mode configuration either as a 1:10 (composite) or a 1:5 (sVideo) DA

•Grouped level (gain) and EQ (peaking) controls

•A video AC/DC coupling selection

•Looping inputs

•Selectable input signal termination

•Standard 19” rack mount size of 1U

Figure 1 and Figure 2 define the unit.

4.2 Connecting the VM-1010

Always switch off the power to each device before connecting it to your

VM-1010. After connecting your VM-1010, connect its power and then

switch on the power to each device.

To connect the VM-1010 as illustrated in the example in Figure 3:

1. Connect up to two video sources (for example composite video players) to

CHANNEL A INPUT A and CHANNEL B INPUT B BNC connectors.

2. Connect up to five video acceptors (for example, composite video recorders)

to each channel.

3. As required, select the coupling and termination, the MODE (2x1:5 or 1:10)

and adjust the EQ and LEVEL of each channel as needed.

8 VM-1010, VM-1021, VN-1055, VM-54 - Your VM-1010

Note:

•Terminate unused inputs to 75, and terminate active inputs at the

connecting source

•Remember, the output signal format matches 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)
