The Extron DTP HDMI 4K 230 Tx is a transmitter for sending HDMI, audio, and bidirectional RS‑232 and IR signals up to 230 feet (70 meters) over a shielded CATx cable to Extron DTP®‑enabled products. It provides an economical and effective means for extending HDMI with embedded multi-channel audio from HDMI-equipped devices. In addition, the DTP HDMI 4K 230 Tx accepts analog stereo audio signals for simultaneous transmission over the same shielded twisted pair cable. It supports video signals at resolutions up to 4K. The compact enclosure size and remote power capability make the DTP HDMI 4K 230 Tx ideal for discreet placement in lecterns, beneath tables, or wherever needed to meet application requirements.
The HDCP-compliant DTP HDMI 4K 230 Tx enables the reliable transmission of HDMI signals, supporting Deep Color up to 12‑bit, CEC pass-through, and embedded HD lossless audio formats. 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 DTP HDMI 4K 230 Tx also provides a connection for sending stereo analog audio to a DTP‑enabled matrix switcher, switcher, or signal processor. The analog stereo audio signal is sent over the same shielded twisted pair cable as the HDMI and control signals, eliminating the need for a separate cable run to support analog audio at the DTP‑enabled product.
The twisted pair transmitter provides other convenient, integrator-friendly features designed to help simplify installation. The DTP HDMI 4K 230 Tx supports simultaneous transmission of bidirectional RS‑232 and IR signals from a control system for AV device control. Also, the transmitter can be remotely powered over the shielded twisted pair cable by a DTP‑enabled product, allowing both devices to share one power supply.
