The Extron DTP HDMI 301 is a transmitter and receiver set for long distance transmission of HDMI video, embedded audio, plus bidirectional control signals over a shielded CATx cable. For added flexibility and convenience, separate analog stereo audio signals can also be transmitted on a second shielded twisted pair cable. It is capable of sending 1080p/60 Deep Color, 1920x1200, and 2K signals up to 330 feet (100 meters). The compact enclosure sizes and remote powering of either unit make the DTP HDMI 301 ideal for extending HDMI, multi-channel audio, and bidirectional control in space-challenged environments.

The HDCP-compliant DTP HDMI 301 enables the reliable, long distance transmission of HDMI signals, supporting Deep Color up to 12-bit, CEC, and embedded HD lossless audio formats. The DTP HDMI 301 streamlines integration with different types of audio signals by allowing direct audio connection from devices with stereo output and providing balanced and unbalanced audio output from the receiver. In addition, DDC communication of EDID and HDCP is continuously maintained between a source and display, ensuring direct compatibility and optimal signal transmission between devices.

The twisted pair extender provides other convenient, integrator-friendly features designed to help simplify installation. The DTP HDMI 301 supports simultaneous transmission of bidirectional RS-232 and IR signals from a control system, providing remote control to source equipment or remote displays. Also, either device can be remotely powered over the original shielded twisted pair cable, allowing both devices to share one external power supply.

The DTP HDMI 301 can be used as a point-to-point solution or integrated with a switching and distribution system to extend inputs or outputs to remote locations. The transmitter and receiver are housed in 1" (2.5 cm) high, quarter rack width metal enclosures. The low profile design of the DTP HDMI 301 allows for discreet placement beneath tables or behind flat-panel displays.

Extron recommends Extron-certified XTP DTP 24 shielded twisted pair cable, shielded RJ-45 plugs, jacks, and couplers engineered for optimum signal transmission with Extron DTP Series products. The XTP DTP 24 cable is certified to 475 MHz, and utilizes a SF/UTP design with four unshielded 24 AWG twisted pair conductors inside an overall braid and foil shield for superior performance and noise immunity.
