HDMI w/ ARC & IR over Twisted Pair Cable Extender Set -- 70m

Twisted pair extenders are notoriously limited in functionality. Most products transmit HDMI and IR reliably, but when it comes to audio -- especially the latest audio return channel (ARC) formats -- extenders simply aren't compatible.

The TechLogix TL-TP70-HD2ARC solves the audio return channel dilemma by delivering HDMI extension, IR and RS232 extension, and ARC processing with coaxial breakout in a single, easy-to-use extender package.

Building from TechLogix's previous generation ARC extenders, the TL-TP70-HD2ARC features 1080p HDMI extension up to 70m, 4K60 HDMI extension up to 40m, flexible power from either the transmitter or receiver, and bi-directional IR and RS232 control.

Additional customer-requested features include a locking power supply, diagnostic LEDs, mounting ears, and field-upgradeable firmware via a micro USB port.

As a final bullet point, the TL-TP70-HD2ARC is TAA-compliant.

Technical Features

  • Transmit HDMI, IR and RS232 over a single twisted pair cable
  • Extend 1080p HD up to 230 ft. (70m.)
  • Extend 4K/30 and 4K/60 UHD up to 130 ft. (40m.)
  • Embedded bi-directional IR and RS232 control
  • System powered from either the transmitter or receiver
  • Audio Return Channel (ARC)


Specification Sheet



  1. Run a twisted pair patch cord with RJ45 connectors between your source device and destination device.
  2. Connect the TL-TP70-HD2ARC transmitter (included in the package) to your source device with an HDMI cable.
  3. Connect the TL-TP70-HD2ARC receiver (included in the package) to your destination device with an HDMI cable.
  4. Optionally connect the ARC and IR control ports if you need audio return de-embedding or control.
  5. Connect the twisted pair patch cord with RJ45 connectors to the twisted pair input ports on the TL-TP70-HD2ARC transmitter and receiver.
  6. Connect the power supply (included in the package) to the DC 12V port on either the TL-TP70-HD2ARC transmitter or receiver.
  7. Connect the power supply (included in the package) to an AC outlet or power source.


What comes in the package?

Each TL-TP70-HD2ARC package includes one transmitter, one receiver, one IR emitter, one IR receiver, two 3-pin terminal blocks, and one power supply.

Can I transmit signals longer than the specified maximum distance?

The maximum recommended distance for the TL-TP70-HDARC is 230 ft. for 1080p signals and 130 ft. for 4K/30 and 4K/60 UHD signals. We don’t recommend exceeding these distances, nor do we guarantee performance beyond the rated specifications.

What if I am running 480i/p or 720p video? Can I send signals further than 230 ft.?

We really don’t recommend it. The product is designed to max out at 230 ft.

Do I need to power the unit?

Yes, we include a power supply that needs to be connected to the transmitter or the receiver—you choose which. You do not need to power both ends.

Do I need to purchase a premade twisted pair patch cable, or can I use the cable I already have?

A bulk shielded twisted pair cable terminated with shielded connectors should work fine…provided the cable is Cat 5e, Cat 6 or better.

Is shielding on the cable and connectors really necessary?

Not necessarily, but it really stinks to pull your cable, seal up the wall, connect your devices and then realize you have electrical interference that is destroying the integrity of your signal. Lots of installations use twisted pair extenders with standard, unshielded cable; however, we don’t warrant the product or guarantee performance unless shielded cables with shielded connectors are installed. Call it a safety net to ensure your system works properly for years to come.

Seriously, is interference that big of deal?

You bet. Both electrical magnetic and radio frequency interference can wreak havoc on digital audio and video signals being transmitted over copper cables—and twisted pair cable (Cat 5e, Cat 6, etc.) is a copper-based system. Think of it as a giant antenna gobbling up all of the stray noise in your building. Shielded cable helps insulate the cable from the noise, and the shielded connectors help drain off any noise that’s collected—just make sure the shielding on the connectors is attached to the shielding on the cables.

Man, EM and RF interference sounds terrible. Is there anything else I can do?

Absolutely…1) run your twisted pair cable in its own conduit; 2) keep electrical cables at least 1 ft. or 0.3m away from the twisted pair cable, and if you have to cross cables make sure to do so at a 90 degree angle; 3) don’t bundle the twisted pair cable with other cables that are carrying voltage (this includes electrical cables, speaker cables, and control cables).

Do you offer a warranty on this device?

We sure do. It’s a standard three year limited warranty. Extended warranties are available from our integration partners and certified resellers. But remember…use that shielded cable and those shielded connectors!
