101L - 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

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 (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 101L 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.

101L - Overview

3 Overview

The high performance 101L Video Line Amplifier is used for amplifying the video signal

intensity and improving the image sharpness (the picture quality) when a video signal is

transmitted over a long cable.

In particular, the 101L features:

Extra-wide bandwidth of 500MHz

Gain and equalization trimmer controls to compensate for signal losses

inherent in long cable runs, recessed to prevent tampering

4 Connecting the 101L

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

101L. After connecting your 101L, connect its power and then switch

on the power to each device.

To connect the 101L, as illustrated in the example in Figure 2, do the following:

1. Connect the video source (for example, a composite video camera) to the

VIDEO IN BNC connector.

It is recommended that you connect the 101L closer to the source than to the acceptor.

2. Connect the VIDEO OUT BNC connector to a video acceptor (for example, a

composite display).

3. Connect the 12V DC power adapter to the power socket on the 101L, and

connect the adapter to the mains electricity.

The ON LED illuminates.

4. If required, adjust the output signal level (LEVEL) and/or cable

compensation equalization level (EQ.) with a small screwdriver.
