Intelix DL-HD70 HDBaseT HDMI Extender Set

Intelix DL-HD70 HDBaseT HDMI Extender Set

The Intelix DigitaLinx DL-HD70 HDBaseT HDMI Extender Set transmits HDMI, bi-directional IR, and RS-232 up to 70 meters (230 feet)* using a single twisted-pair cable, such as Cat-5 or Cat-6.

VP of Technology, Cameron Smith said, "The DigitaLinx brand rekindles Liberty’s commitment to affordability without sacrificing quality.”

Appropriately, the DigitaLinx
DL-HD70 HDMI Extender delivers performance and features not typically seen in HDBaseT extenders priced under $350 (MSRP) per set. In addition to extending HDMI, RS232, IR, and Ethernet up to 70 meters (230 feet)* over twisted-pair cable, the units feature flexible power, field-upgradeable firmware, built-in surge protection, and a best-in-industry compact chassis specifically designed for mounting behind ultra-slim flat panels.

The system supports many of the features associated with the HDMI v.1.4 spec, including (but not limited to) resolutions ranging from 800x600 through 1920x1200, 1080p, 4k x 2k, Deep Color, 3D, PCM 8-channel audio, Dolby Digital TrueHD Audio, and DTS HD Master Audio.  The included hardware and signal pathways also accommodate bi-directional IR and RS-232 control.

The kit is complete as follows:

  • (1) DL-HD70 Transmitter
  • (1) DL-HD70 Receiver
  • (1) Power Supply with locking connector (use at either transmitter or receiver end)
  • (1) US Power Cord
  • (2) IR Receiver
  • (2) IR Emitter
  • (2) 3-Pole Euroblock Terminal Block for RS-232
  • (4) Mounting Brackets with Screws
  • Installation Guide

The system may be powered at either transmitter or receiver end, for maximum installation flexibility and convenience.

As with virtually all systems that are based upon twisted-pair cable technology, the Intelix DigitaLinx DL-HD70 will work with virtually any twisted-pair cables, including Cat-5e and Cat-6, but range and system bandwidth are directly related to both distance and cable quality, so to get the highest resolutions at the greatest distances, you will want high-quality, low-skew cables. Check the Installation Guide for more information. If you want the very best pre-terminated unshielded Cat-6 cables, please consider our VideoTwist cables.

Like most Intelix products, the DL-HD70 comes with a two year limited warranty from the manufacturer.

* Range is dependent upon resolution, color depth, twisted-pair cable quality and other factors.  Please consult the spec sheet for details.

Built-in surge protection and diagnostic LEDs ensure hassle-free and robust installations. Flexible power design allows the units to be powered at either the TX or RX end, and only one power supply is required. The 12 volt power supply is secured with a screw-on connector to prevent the power from being accidentally disconnected.

The DL-HD70 is sold only as a set. All accessories are included including two IR emitters, two IR receivers, and two pairs of mounting brackets with screws. The individual transmitter and receiver are not compatible with other HDBaseT devices due to proprietary PoE [aka PoH] circuitry.
