HT-Air MkII™ Wireless

REL have acquired a sterling reputation within the industry for delivering great sounding, reliable wireless delivery of the REL experience. The freedom this confers on our customers produces several benefits; it permits ultra-high performance without the cumbersome tether of a cable, permits careful placement without being limited by the length of a cable and can lead to a better sounding, less cluttered experience.
HT-Air MkII™ Wireless is our latest method of distributing 5.8 Ghz wireless and delivers .1/LFE or stereo Low Level performance similar to our more expensive wireless systems quickly, reliably and without the thin, non-dynamic sound many wireless systems deliver. In part, this is achieved by eliminating the often very slow delivery methods offered by off-the-shelf Bluetooth and wi-fi based systems.
We, at REL, are committed to delivering the highest quality listening experience for our customers; HT-Air MkII™ is yet another way in which we show we are listening to you.

Connecting Up

The REL HT-Air MkII™ Wireless is intended to be used with the Serie HT or similar REL sub bass system. The transmitter and receiver will require power from an AC wall plug using the power adapter cables supplied.
It is not possible to use the HT-Air MkII™ Wireless connection and a direct connection simultaneously. Using both wired and wireless connections simultaneously could result in damage and voids all warranties.
Always switch your system off before disconnecting any wires.
With the HT-Air MkII™, there are two basic ways to connect and setup. The first is a single channel input from the sub out of a theater or power speaker system. In this case a single RCA cable is needed from the source to the transmitter.

Theater connection

  • Connect RCA cable from Sub Out of theater processor to LFE input of the HT-Air MkII™ transmitter.

Then use the second RCA from the LFE output of the HT-Air MkII™ receiver to the LFE input of the REL.
The second is a stereo input from a stereo preamp or powered speaker system. You will need to use two RCA cables.

Powered Speaker connection

  • Connect RCA from L/R output of the source to the inputs of the HT-Air MkII™.

Then use two more RCA cabels and connect from the L/R outputs of the HT-Air MkII™ receiver to the inputs of the REL.

Pairing

Now that the HT-Air MkII™ Wireless transmitter and receiver are connected to your system, the unit will need to be paired.

  1.  Make sure that the transmitter AC to DC wall plug supply is connected to an AC outlet, and that the barrel connector is connected to the transmitter.
  2. Make sure that the receiver AC to DC wall plug supply is connected to an AC outlet, and that the barrel connector is connected to the receiver.
  3.  Make sure that the sub is plugged into an AC outlet using the supplied AC cable and that the sub is turned on. Power switch is located on the rear panel.
  4. At this point the transmitter and receiver should find each other and pair together. This will be indicated by the “Pair” LEDs on both the transmitter and control panel staying lit (no flashing).
  5. In the event that the transmitter and receiver do not automatically pair, simply exercise the momentary “Pair” button on the receiver until the LED flashes.
  6.  Then exercise the “Pair’ button on the transmitter.
  7.  When correctly paired, the LEDs on both units will stop flashing and stay solid within 5 seconds.
