3 Overview
The Kramer PT-102VN is a distribution amplifier for composite video or SDI
signals. It takes one input, provides correct buffering and isolation and distributes
the signal to two identical outputs.
•Accepts a single input and distributes it to 2 identical outputs using BNC
connectors
•Has a bandwidth of 430MHz, ensuring that it remains transparent even in the
most critical applications
•Has gain and equalization (EQ.) controls to compensate for cable losses
•Is ideally suited to work with the Pico TOOLS™ PT-102AN 1:2 Audio DA
Achieving the best performance means:
•Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
•Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your PT-102VN in a
location free from moisture and away from excessive sunlight and dust

5 Using the PT-102VN 1:2 Video DA
You can connect your PT-102VN:
•As a 1:2 video DA (see section 5.1)
•To a 4x1VB 4x1 High Resolution Video Switcher to increase the number of
inputs (see section 5.2)
•To two 105VB 1:5 High Resolution Video DA units to increase the number of
outputs (see section 5.3)
5.1 Connecting the PT-102VN 1:2 Video DA
To connect the PT-102VN 1:2 Video DA, as the example in Figure 2illustrates,
connect the following1
1. Connect a composite video source (for example, a composite video
player) to the INPUT BNC connector.
:
2. Connect the two OUT BNC connectors to up to two composite video
acceptors, as follows:
Connect the OUT 1 connector to video acceptor 1 (for example, a
projector)
Connect the OUT 2 connector to video acceptor 2 (for example, a
display)
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
4. If required, adjust the output signal level and/or cable compensation
equalization level.
1 Switch OFF the power on each device before connecting it to your PT-102VN. After connecting your PT-102VN, switch on
its power and then switch on the power on each device

5.2 Increasing the Inputs
When it is necessary to handle more than one input, you can increase the number
of inputs for example, from one to four, by connecting the Kramer 4x1VB 4x1
High Resolution Video Switcher1in addition to the PT-102VN 1:2 Video DA, as
the example in Figure 3illustrates:
1. Connect up to four sources to the four IN connectors of the 4x1VB.
2. Connect the OUTPUT connector of the 4x1VB to the INPUT connector
of the PT-102VN.
3. Connect the OUT connectors of the PT-102VN to up to two acceptors.
4. Select the desired input via the INPUT SELECTOR switch of the 4x1VB.
5. Connect the 12V DC power adapter to the power socket of the
PT-102VN and connect the adapter to the mains electricity.
6. Adjust the output signal level and/or cable compensation equalization
level of the PT-102VN, if required.

5.3 Increasing the Outputs
The PT-102VN can be cascaded with other high quality distribution amplifiers to
distribute a video source to more than two outputs. For example, you can increase
the number of outputs from two to ten, by connecting a PT-102VN 1:2 Video DA
unit to two Kramer 105VB 1:5 High Resolution Video DA units, forming a 1:10
DA, as the example in Figure 4illustrates:
To form a 1:10 DA, do the following:
1. Connect a source to the INPUT BNC connector of the PT-102VN.
2. Connect the OUT 1 BNC connector of the PT-102VN to the INPUT BNC
connector of the first 105VB.
3. Connect the OUT 2 BNC connector of the PT-102VN to the INPUT BNC
connector of the second 105VB.
4. Connect the five OUT BNC connectors of the first 105VB to the video
acceptors 1 to 5, and connect the five OUT BNC connectors of the second
105VB to five video acceptors as well.
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (for the PT-102VN and both 105VB
units).
6. Adjust the output signal level and/or cable compensation equalization
level of the PT-102VN, if required.
