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.

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.
