104R - 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 104R 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.

before installing

2.3 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

104R - Overview

3 Overview

The 104R is a high−performance distribution amplifier for RF signals. It takes one

RF (CATV/MATV) signal and distributes it to four identical outputs.

In addition, the 104R features:

A single RF input such as a typical CATV/MATV signal and distributes it to

four identical outputs

Extra wide bandwidth of up to 800 MHz, ensuring that the unit remains

transparent in the most critical applications

Matches the inputs and outputs to 75Ω impedance

Comes with convenient screw-on “F” type connectors

4 Connecting the 104R

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

104R. After connecting your 104R, connect its power and then switch

on the power to each device.

To connect the 104R as illustrated in the example in Figure 2:

1. Connect the TV source (for example, a satellite receiver) to the “F” type

INPUT connector.

2. Connect one or more of up to 4 of the following “F” type OUT connectors to

the respective TV acceptors:

You do not have to connect all the outputs.

OUT 1 to TV acceptor 1 (for example, a TV)

OUT 2 to TV acceptor 2 (for example, a TV)

OUT 3 to TV acceptor 3 (for example, a recorder)

OUT 4 to TV acceptor 4 (for example, a TV)

3. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity.

4. Switch on the TV source and the TV acceptors.

The RF INPUT signal automatically distributes to the TV acceptors.
