HT-Air MkII™ Wireless
REL have acquired a sterling reputaon within the industry
for delivering great sounding, reliable wireless delivery
of the REL experience. The freedom this confers on our
customers produces several benets; 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 beer sounding, less
cluered experience.
HT-Air MkII™ Wireless is our latest method of distribung
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 eliminang the oen very slow delivery
methods oered by o-the-shelf Bluetooth and wi-
based systems.
We, at REL, are commied 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.

The REL HT-Air MkII™ Wireless is intended to be used with
the Serie HT or similar REL sub bass system. The transmier
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 connecon
and a direct connecon simultaneously. Using both wired
and wireless connecons simultaneously could result in
damage and voids all warranes.
Always switch your system o before disconnecng any wires.
With the HT-Air MkII™, there are two basic ways to connect
and setup. The rst 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 transmier.
Connecng Up

Theater connecon
– Connect RCA cable from Sub Out of theater processor to
LFE input of the HT-Air MkII™ transmier.
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 connecon
– 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.

Now that the HT-Air MkII™ Wireless transmier and
receiver are connected to your system, the unit will need
to be paired.
1 Make sure that the transmier AC to DC wall plug supply is
connected to an AC outlet, and that the barrel connector
is connected to the transmier.
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 transmier and receiver should nd
each other and pair together. This will be indicated by
the “Pair” LEDs on both the transmier and control
panel staying lit (no ashing).
5 In the event that the transmier and receiver do not
automacally pair, simply exercise the momentary “Pair”
buon on the receiver unl the LED ashes.

6 Then exercise the “Pair’ buon on the transmier.
7 When correctly paired, the LEDs on both units will stop
ashing and stay solid within 5 seconds.
Pairing is persistent and will not be lost when unplugged.
Care
The units are best maintained by using a damp (not wet)
cloth to remove dust. Do not place objects, such as drinks
on top of your REL Air transmier. Never use a dry cloth on
this nish to prevent scratches.
