Model Version Description Part #
XTP CP 4i 3G-SDI Four Input Board, 3G-SDI w/ Stereo Audio 70-1050-01

The Extron XTP CP 4i 3G-SDI board provides four inputs for connection of 3G-SDI signals into any XTP II or XTP CrossPoint® matrix switcher. Each input features automatic equalization to optimize signal quality over long cable runs, plus buffered loop-throughs with reclocking to support local monitors or additional distribution needs. Also, four analog stereo audio inputs offer embedding capability and two channel AES audio extraction allows flexible audio management and breakaway audio switching. The XTP CP 4i 3G-SDI supports signal rates up to 2.97 Gbps, and is ideal for connection of remote PTZ cameras and other broadcast video sources in professional applications, such as videoconference environments and live events.

The XTP CP 4i 3G-SDI also features four balanced/unbalanced stereo audio inputs with audio breakaway capability for switching and distribution flexibility. Analog audio signals are digitized to two-channel PCM digital audio for separate audio routing within the system. To simplify integration, stereo audio can also be embedded into the signal stream for distribution alongside video and control signals. Incoming signals can be switched to an XTP® output board for local or remote signal distribution.

To compensate for weak source signals or signal loss from a long input cable, the XTP CP 4i 3G‑SDI offers automatic input cable equalization and reclocking on the buffered SDI loop-throughs. Input equalization restores and reshapes incoming signals, ensuring optimal signal quality throughout the system. It also applies SD Pro processing to deinterlace 480i and 576i video signals for reliable display on a variety of output devices.

Extron XTP Systems

Extron XTP Systems provide a completely integrated switching and distribution solution for multiple digital and analog formats. They support local connectivity as well as extended transmission capability for sending high resolution video, audio, RS‑232, and Ethernet up to 330 feet (100 meters) over a shielded CATx cable and even greater distances over fiber optic cabling. Each system is HDCP compliant and delivers ultra‑fast, highly reliable digital switching with Extron's SpeedSwitch® Technology.

At the heart of a system is an XTP matrix switcher. The modular matrix switchers are expandable from 4x4 to 64x64, depending on frame size, and can be populated with a wide variety of XTP I/O matrix boards. Input and output boards provide direct HDMI, DVI, 3G‑SDI, VGA, video, and audio connections to local sources and displays, and signal extension to remote endpoints when using XTP transmitters and receivers. The matrix switcher can also provide power to a remote XTP device over CATx cabling, depending on transmitter model.

The online XTP System Builder gives convenient access for complete system design. The tool also features a printable bill of materials, pricing, and quote submittal. Once the order is confirmed and received, the included XTP System Configuration Software enables easy setup and configuration right out of the box.

To configure, operate, and monitor the system in real time, user-friendly control software offers a complete view of all XTP devices from a computer. With hot‑swappable modular components, a wide selection of XTP transmitters and receivers, and advanced 24/7 system monitoring, XTP Systems are designed to provide continuous, trouble-free operation in the most critical applications.


Note: When installing this board in existing XTP Systems, new firmware for the matrix switcher may be required; contact your Extron technical services representative for more information.
