2. Download up-to-date Kramer user manuals from the Internet at this URL: http://www.kramerelectronics.com/manuals.html
3. The complete list of Kramer cables is on our Web site at http://www.kramerelectronics.com (click “Cables and Connectors” in the Products section)

Overview

The Pico TOOLS micro-sized high performance 1:2 distribution amplifiers that are described in this user manual include the following:

• PT102A, see section 3.1

• PT102S, see section 3.2

• PT102VN, see section 3.3
  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 micro-sized 1:2 DA in a location free from moisture and away from excessive sunlight and dust

3.1 About the PT102A 1:2 Audio DA
The PT102A 1:2 Audio DA is a micro-sized high performance 1:2 distribution amplifier for unbalanced¹ stereo audio signals² . The PT102A:

• Accepts a single input and distributes it to 2 identical outputs using
  3.5mm mini connectors

• Has separate left and right gain controls for optimizing signal levels

• Is ideally suited to work with the Pico TOOLS PT102VN 1:2 Video DA and the Pico TOOLS PT102S 1:2 s-Video DA
  Figure 1 and Table 1 define the PT102A 1:2 Audio DA:

Table 1: Features and Functions of the PT102A 1:2 Audio DA

1. You can use the PT102A to distribute a balanced mono audio signal, via readily available adapter cables
2. For example, portable cassette and CD players
3. Insert a screwdriver into the hole and carefully rotate it, to trim the level

3.2 About the PT102S 1:2 s-Video DA
The PT102S 1:2 s-Video DA is a micro-sized high performance 1:2 distribution amplifier for s-Video (Y/C) signals. The PT102S:

• Accepts a single input and distributes it to 2 identical outputs using 4 pin connectors
• Has a bandwidth of 150 MHz, ensuring that it remains transparent even in the most critical applications
• Has separate chrominance and luminance gain controls
• Is ideally suited to work with the Pico TOOLS PT102A 1:2 Audio DA
  Figure 2 and Table 2 define the PT102S 1:2 s-Video DA:

3.3 About the PT102VN 1:2 Video DA
The PT102VN 1:2 Video DA is a micro-sized high performance 1:2 distribution amplifier for composite video signals. The PT102VN:

• Accepts a single input and distributes it to 2 identical outputs using BNC connectors
• Has a bandwidth of 470 MHz, 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 PT102A 1:2 Audio DA
  Figure 3 and Table 3 define the PT102VN 1:2 Video DA:

Table 3: Features and Functions of the PT102VN 1:2 Video DA

Using the PT102VN 1:2 Video DA

You can connect your PT102VN:

• As a 1:2 video DA (see section 4.1)
• To a 4x1VB 4×1 High Resolution Video Switcher to increase the number of inputs (see section 4.2)
• To two 105VB 1:5 High Resolution Video DA units to increase the number of outputs (see section 4.3)
  Note: similar principles apply when using the PT102A or the PT 1 02S.

4.1 Connecting the PT102VN 1:2 Video DA
To connect the PT102VN 1:2 Video DA, as the example in Figure 4 illustrates, connect the following ¹ :

1. Connect a composite video source (for example, a VCR) to the INPUT BNC connector.

2. Connect the 2 OUT BNC connectors to up to 2 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 monitor)

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

4. Adjust the output signal level and/or cable compensation equalization level, if required.

Switch OFF the power on each device before connecting it to your PT102VN. After connecting your PT102VN, switch on its power and then switch on the power on each device

4.2 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 a 4x1VB 4×1 High Resolution Video Switcher¹ in addition to the PT102VN 1:2 Video DA, as the example in Figure 5 illustrates:

1. Connect up to 4 sources to the 4 input connectors of the 4x1VB.
2. Connect the OUTPUT connector of the 4x1VB to the INPUT connector of the PT102VN.
3. Connect the output connectors of the PT102VN to up to 2 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 PT102VN and connect the adapter to the mains electricity.
6. Adjust the output signal level and/or cable compensation equalization level of the PT102VN, if required.

4.3 Increasing the Outputs
The PT102VN 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 PT102VN 1:2  Video DA unit to two 105VB 1:5 High Resolution Video DA units, forming a 1:10 DA, as the example in Figure 6 illustrates:
1 A mechanical switcher that lets you select any input to route to one output via its INPUT SELECTOR buttons. Alternatively, you could connect the PT102VN to a video switcher with more than 4 inputs
To form a 1:10 DA, do the following:

1. Connect a source to the INPUT BNC connector of the PT102VN.
2. Connect the OUT 1 BNC connector of the PT102VN to the INPUT BNC connector of the first 105VB.
3. Connect the OUT 2 BNC connector of the PT102VN to the INPUT BNC connector of the second 105VB.
4. Connect the 5 OUT BNC connectors of the first 105VB to the video acceptors 1 to 5, and connect the 5 OUT BNC connectors of the second 105VB to the video acceptors 6 to 10.
5. Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity (for the PT102VN and both 105VB units).
6. Adjust the output signal level and/or cable compensation equalization level of the PT102VN, if required.
