Introduction

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 groups1

Thank you for purchasing your Kramer mechanical switcher, which is ideal

for a system in which a passive, hard-wired signal path is preferred.

that are clearly

defined by function.

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 cables2

Each package includes the following items:

•The one or more Kramer mechanical switchers

•This user manual3

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).

•Avoid interference from neighboring electrical appliances that

may adversely influence signal quality and position your Kramer

switcher away from moisture, excessive sunlight and dust

3.1 Your VS-44AV 4x4 Video Audio Matrix Switcher

The Kramer VS-44AV 4x4 Video Audio Matrix Switcher is a high-quality

mechanical 4x4 matrix switcher for composite video and stereo audio

signals. The VS-44AV is designed to simultaneously route up to 4 sources

each to any one of 4 available outputs. The VS-44AV is unique in allowing

4 different cross points of video and stereo audio to operate at the same

time. However, it cannot simultaneously distribute an input signal to

multiple outputs. The high-quality input selector buttons are color coded for

easy identification and unselected inputs are terminated via 75Ωresistors.

3.2 Your VS-81AV 8x1 Video/Audio-Stereo Switcher

The Kramer VS-81AV, 8x1 Video/Audio-Stereo Switcher is a high-quality

mechanical 8x1 switcher for composite video and stereo audio signals.

The VS-81AV is designed for applications requiring an unpowered rack-

mountable unit for routing of video and stereo audio signals. Audio is

always switched together with the corresponding video signal and

unselected video inputs are terminated via 75Ωresistors. High-quality

switching components provide excellent isolation between inputs. Its

unpowered passive design is advantageous for applications in which various

regulatory compliances would otherwise be required. The "hard-wired"

signal path offers excellent bandwidth, and can even switch other signal

formats.

quality mechanical 8x1 switcher for s-Video (Y/C) and stereo audio

signals using 4-pin and RCA connectors. The VS-81AYC is designed for

applications requiring an unpowered rack mountable unit for the routing

of s-Video (Y/C) and stereo audio signals. Audio is always switched

together with the corresponding s-Video (Y/C) signal and unselected

video inputs are terminated via 75Ωresistors. High quality switching

components provide excellent isolation between inputs. Its unpowered

passive design is advantageous for applications in which various

regulatory compliances would otherwise be required. The "hard-wired"

4 Connecting Kramer Mechanical Switchers

This section gives examples of how to connect Kramer mechanical

switchers.

•To connect a mechanical video switcher, see the example in section 4.1

•To connect a mechanical audio switcher, see the example in section 4.2

•To connect a mechanical audio/video switcher, see the example in

section 4.3

4.1 Connecting a VS-81V 8x1 Video Switcher

To connect your VS-81V 8x1 Video Switcher, as the example in Figure 6

illustrates:

1. Connect up to 8 composite video sources to the appropriate BNC input

connectors.

2. Connect the BNC OUTPUT connector to the composite video acceptor.

Pushing a front panel INPUT selector button routes that composite video

source to the composite video acceptor.
