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
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

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

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.

4 Connecting the 104R
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.
