In recent years, Kramer has redesigned and upgraded most of its lines, rendering the products more efficient and “user-friendly”. Kramer’s line of professional video/audio electronics is one of the most versatile and complete available and is a true leader in terms of quality, workmanship, price/performance ratio and innovation. -
Page 5: Video Tester
(1:5 Video Stereo Audio Distribution Amplifier) is an exceptionally high performance 1:5 distribution amplifier for video and stereo audio signals that can be serially connected between a receiver and an acceptor for video/audio distribution purposes. It accepts one input signal, (composite, single component, or serial digital video), and distributes it to five identical outputs using BNC connectors for video, and RCA connectors for audio. - Page 6 TWISTED PAIR INTERFACES AND KRAMER TOOLS This manual includes information about configuration, operation, maintenance and optional accessories for the following Twisted Pair Interfaces and Kramer Tools (please note that machines from the same family have several features in common): TP-1xl- Video Line Transmitter...

- Page 8 Getting to Know the TP-1xl Video Line Transmitter The Kramer TP-1xl is a high performance composite video to twisted pair transmitter, designed to transmit video signals over long distances using common twisted-pair cable. Combined with the TP-2xl, this set of machines is an upgrade of the TP-1N/TP-2N pair (now discontinued).
- Page 9 Getting to Know the TP-2xl Video Line Receiver The Kramer TP-2xl is a high performance composite video to twisted pair receiver, designed to receive video signals over long distances using common twisted pair cable. Combined with the TP-1xl this set of machines is an upgrade of the TP-1N/TP-2N pair (now discontinued).
- Page 10 Getting to Know the TP-6, Twisted-Pair Line Amplifier The KRAMER TP-6, Twisted-Pair Line Amplifier, extends the range of the KRAMER TP (twisted-pair transmitter-receivers) series, to almost any desired distance. The TP-6 may receive its power source through the twisted-pair wire (in a 4-wire setup) and, due to its very small power consumption, several units may be cascaded and fed from one standard 12V DC feed.
- Page 11 Getting to Know the TP-11N, Video/Audio Twisted-Pair Line Transmitter The KRAMER TP-11N Video Line Transmitter sends a color video signal and a stereo audio signal over long distances using a telephone wire or any other twisted-pair wire. The TP-11N maintains the bandwidth of an industrial color video signal up to several hundred meters and broadcast quality (over 6 MHz) signals up to 100 meters.
- Page 12 Getting to Know the TP-12N Video/Audio Twisted-Pair Line Receiver The KRAMER TP-12N Video/Audio Line Receiver works in conjunction with the TP-11N Video/Audio Line Transmitter. The TP-12N allows parallel connection of several units on the same line (one transmitter/multiple receivers), that can be tapped at any point without affecting image quality. When connecting several units, all the termination switches on the rear panel of the TP-12N machines, except for the last on the line, should be toggled to the Hi-Z position.
- Page 13 Getting to Know the TP-11xl, Video/Audio Twisted-Pair Line Transmitter The KRAMER TP-11xl Video Line Transmitter, which is based on the latest technology, sends a color video signal and a stereo audio signal over long distances using a telephone wire or any other twisted-pair wire. The TP-11xl maintains the bandwidth of an industrial color video signal up to several hundred meters and broadcast quality (over 6 MHz) signals up to 100 meters.
- Page 14 Getting to Know the TP-12xl Video/Audio Twisted-Pair Line Receiver The KRAMER TP-12xl Video/Audio Line Receiver, which is based on the latest technology, works in conjunction with the TP-11xl Video/Audio Line Transmitter. The TP-12xl allows parallel connection of several units on the same line (one transmitter/multiple receivers) that can be tapped at any point without affecting image quality.

A termination switch allows several 704 receivers to be looped-through on the same line (one transmitter-multiple receivers.)
- Page 17 TOOLS family, are used as a pair for transmitting video and mono audio over long distances using twisted-pair wire. A termination switch allows several 708 receivers to be looped-through on the same line (one transmitter - multiple receivers). This pair of machines is best at distances of up to 200 meters. At shorter distances, they provide close to broadcast level performance.
- Page 18 Getting to Know the 709/710 Y/C Line Transmitter/Receiver The KRAMER 709 Y/C Line Transmitter and the 710 Y/C Line Receiver, part of the KRAMER TOOLS family, are used as a pair for transmitting s-Video (Y/C) over long distances using 2 twisted-pair sets of wires.
- Page 19 The KRAMER 711 (xl) Video/Audio Line Transmitter and the 712 (xl) Video/Audio Line Receiver, part of the KRAMER TOOLS family, are used as a pair for transmitting video and stereo audio over long distances using 3 pairs of wires (6 wires). The frequency response of the system is well over 64 MHz. The machines offer user controlled Video Gain and Video EQ.

Page 20: Installation
Connecting Kramer Tools to Video Devices Video sources and output devices (such as monitors or recorders) are connected to the 704/705, 707/708 and 711/712 models through BNC connectors. The 709/710 models are connected by 4-pin type connectors. -
Page 21: Gain Control
In this way, all 3 receivers can output the transmitted signal. The operator must switch the termination switches of all the Twisted-Pair Interfaces/Kramer Tools except for the last to " Hi- Z " position. The last machine' s termination switch should always be in the " Term " position in order to maintain a well-matched balanced line from the first to the last Twisted-Pair Interface/Kramer Tool. - Page 22 As longer cables are used, the problem is aggravated, resulting in fine detail loss as well as in color degradation. Hence, it is necessary to compensate for the loss by using the Twisted Pair/Kramer Tool HF/EQ. control trimmer; equalization is performed by first connecting a Color Bar Generator to a Twisted Pair Interface/Kramer Tool transmitter input.

Page 23: Audio Control
(VCR) is sent over long distance by the TP-11N, using a telephone wire or any other twisted pair wire. The TP-12N (Video Line Receiver) at the other end of the wire receives the signal and transfers it to an acceptor. - Page 24 707 (Video/Audio Line Transmitter), using a telephone wire or any other twisted pair wire. The 708 (Video/Audio Line Receiver) at the other end of the wire, receives the signals and transfers them to video and audio acceptors.
- Page 25 Toggle all termination switches on all the receivers except for the last to "Hi-Z" position. Toggle the last receiver' s termination switch to "Term" position (see section 11.2 for more details). If the high frequency response must be adjusted, first use the controls of the transmitter, and then fine-tune each receiver with its appropriate control for optimal results.
