Introduction
NuForce Air DAC's wireless technology lets you stream music from yourcomputer USB port, iPhone,
iPad
or iPod to up to four different receivers throughout your home or office. Easily get CO-quality
sound
with no latency and no interference throughout your environment-wirelessly, with Air DAC.
The NuForce Air DAC wireless DAC/receiver and associated TX transmitters are based on a new wireless
technology known
as SKAA (www.skaa.com). SKAA provides seamless operation and aconsistent user
interface across different
SKAA devices. SKAA technology has several advantages resulting in CO-
quality sound and ease of setup described in more detail below.
Air DAC offers:
0 CO-quality sound, no latency, no interference with other Wi-Fi signals
0 Simple control and setup- no software, setup or pairing
0 Stream music to up to four receivers, and from up to four devices
0 Works with any digital audiofrom music, movies, and games
0 Works anywhere without interference- no wifi "hot spot" needed for reception
About theAir DAC and SKAA wireless technology
With Air DAC, you don'tmove to the music-the music moves with you.
The Air
DAC Wireless System is acombination wireless transmitter (iTX or uTX) and radio receiver (Air
DAC) that operates in the 2.4GHz radio band. The Air DAC Receiver utilizes a premium quality Digital-
to-Analog Converter
(DAC) stage and simple one-button SKAA control.
Unlike similar devices,
the Air DAC and associated TX transmitters do not experience the typical loss in
sound quality
or interference capability of cell phones and other wireless devices. Rather, they offer CO-
quality sound, virtually no latency, a 15-30 meterrange, and a spread-spectrum technology that
detects and chooses from among available frequency spectrums in order to avoid interference.
The NuForce Air
DAC Wireless Receiver and any device fitted with an appropriate matching TX
transmittercan be combined to form a wireless audio network. Each transmittercan send audio to four
receivers, and each receiver
can connect to as many as four transmitters.
Just linkyour Apple mobile device wirelessly
to multiple amplifier/speaker systems located throughout
your home.Then simply walk into any room with your portable player-the system automatically locks
on
to its signal-and stream your music to the speakers in that space. Move to the next room and
stream music from the same device
to that room's receiver or pair of speakers. Wherever you roam in
your home or office, your music is with you.
Features:
4
0 Can receive and lock with up to four independent iTX-1 00/uTX-1 00 transmitters.
0 Simple operation -Use the single front-panel switch to step through each of the available
transmitters
within range of the receiver. The cycle returns to first transmitter after selecting tl'le
last available transmitter.
0 CO-quality performance
0 Extra-wide wireless audio range covers larger environments- iTX-1 00 range approximately
spans 10-20m;
uTX-1 00 range spans approximately 15-30m depending on conditions.
0 uTX (for USB device) Transmitter is cross-platform (Mac/PC), so there's no need to install drivers.
0 The iTX similarly connects to astandard analog dockwhen mated with Apple iPod , iPhone and
iPad.

Air
DAC/TX UserSetup
There are numerous ways
that
the
Air
DAC
I
TX
system can be configured. Here are a
few
guidelines
to
helpyou
get
started. Once you become familiar
with
operating
the
system you will be able
to
easily
configure
it
for
other, more advanced applications.
In
addition, we have included adetailed listing
below
of
the
Air
DAC's
SKAA
operating controls
to
help in setting
up
whatevertype
of
system you
might
be considering.
QuickStart
Guide
Start Here-System Connection
to
Apple
Mobile
Devices (iPod, iPhone, iPad)
The majority
of
users will likely be connecting
the
system
to
Apple Mobile Devices such
as
an
iPod for
multiple-room music playback.
If
that
is
yourgoal, then here
is
the place
to
start.
Even
if
you are
planning a more advanced application,
it
might
be agood idea
to
try
setting
up
this simple system
mst
in order
to
become familiar
with
how
everything works.
1)
Connect
the
iTX
transmitter
to
the
base
of
the
iPod. Start playing music from the iPod and set the
volume
to
maximum.
2)
Plug the Air
DAC
into
the
AC
power
outlet
and check
to
make sure
it
is
turned on.
3)
Connect the
L&R
RCA
audio outputs
of
the
Air
DAC
via quality interconnectcables
to
an
unused
input
of
your
home stereo system (or
other
amplifier/speaker combination).
4)
After approximately one minute, the Air
DAC
will recognize and bond
with
the
signal coming from
the iTX/iPod. Once bonded,
that
iTX/iPod will automatically be added
to
the
Air
DAC's
Green List
of
favorite devices.
5)
If
you
would
rather
not
wait
(as
in step
4)
for the Air
DAC
to
automatically
bond
with
your
iPod (or
it
fails
to
do
so
for
some reason), then double-clickthe Air
DAC's
front
panel
SKAA
button.
At
this point,
the Air
DAC
will begin
hunting
forthe
radio signal coming from
the
iTX
transmitterconnected
to
your
iPod. Once
it
detects the signal,
it
should bond
to
it. When the process
is
completed,
the
LED
at
the
front
of
the
Air
DAC
should turn
AMBER.
6)
At
this point, you may wish
to
manuallyadd
the
iPod
to
the
Air
DAC's
Green List. To
do
so
push and
hold
the
front
panel
button
on
the
Air
DAC
for
aboutthree seconds until the
AMBER
LED
turns
GREEN.
Once completed,
that
iTX/iPod will be automatically recognized
by
the Air
DAC
every
time
it
comes
within
the vicinity.
7)
Set
the
volume control
of
the stereo system
to
the
minimum
position and then turn on
the
AC
power.
8)
Slowly
turn
up
the
stereo system's volume
to
the
9 o'clock position.
9)
Listen
forthe
sound
of
music playing through
the
speakers.
If
you hear music, turn
the
stereo
system
up
to
the
desired listening level.
If
you
do
not
hear music, turn
the
volume
of
the stereo system
back
down
and then repeat steps 5
through
9.
System Connection
to
a Computer
1)
Connect
the
uTX transmitter
to
an
available
USB
port
on
the
computer.Start playing music from
the computer's media software player and set
the
volume
to
maximum
(0
dBFS).
Check
that
the
computer sound device
is
configured
to
play from
SKAA
USB
Audio device.
2)
Repeat steps 2
through
9 above.
Creating a
Cluster
6
Acluster
is
a method wherebyseveral Air
DAC
units can be combined in away
that
allows one
unit
to
be in control
of
up
to
three others.
In
such a system, the
front
panel
button
SKAA
control
of
the
Master
unit
directs
the
operation
of
all
the
system's
other
Slave units.Once a preferred source
is
selected from
the Green List on the Master unit, all
ofthe
Slave units will then switch
to
the same source.
If
a
new

rlU
FDICE
source
is
desired at afuture point,
it
must be selected via cycling through the sources stored in the
Master's Green List.
Typically, such
an
arrangement
might
occur where you would have several Air
DAC
/AmplifierI Speaker
systems located in several rooms and configured
so
that
you could move about your home
with
an
iPod playing in your pocket.This arrangement would allow you
to
have music follow you from room
to
room
without
the
need
to
change control settings on any
of
the
other
Air
DAC
receiver systems.
Another application
might
apply
to
a pair
of
mono
amplifiers
(i.e.,
one channel each) configured for
stereo playback and separated
by
a distance in which signal wires going
to
each
is
not
a practical
option.
In
that
case,
you would assign one Air
DAC
unit
to
each amplifier and
use
only the appropriate
Left or Right channel
of
each
to
feed a given amplifier.
In
any
case,
the following procedures will apply:
1)
Connect
the
appropriate
iTX
or
uTX
transmitter
to
the
source device.Start playing music from the
source and set
the
volume
to
maximum.
2)
Locate
the
number
of
Air
DACs
you will be using at their designated locations, making sure that
AC
power
is
available nearby.
3)
Connect
the
appropriate
RCA
audio outputs
of
each Air
DAC
via quality interconnect cables
to
the
inputs
of
each amplifierI speaker combination.
4)
Power
the
Master
unit
to
On while holding
down
the
SKAA
button
until
RED
LED
starts flashing.
5)
Power each
of
the
remaining Air
DAC
receiver units On.
6)
Once
the
LED
on
the
Master becomes solid (stops flashing), turn
off
the Master and all
of
the other
Slave
Air
DAC
receiver units.
7)
The cluster
has
been successfully made.
Now
turn on the Master and
Slave
units.
8)
For each location, set
the
volume control
of
the
amplifierI speaker system
to
the
minimum
position and then
turn
on
the
AC
power.
9)
Slowly
turn
up
the
volume
of
each amplifierI speaker system
to
a9 o'clock position.
1
O)
Listen for
the
sound
of
music playing
through
the
speakers on each system. Ifyou hear music,
then turn
the
system volume
up
to
the desired listening level.
If
you
do
not
hear music, turn the volume
of
the
system back down, turn
off
all Master
&
Slave
units, and then repeat steps 4 through
10
.
Dismantling a Cluster
At some
point
after having created acluster you may wish
to
return the Air
DAC
receivers back
to
stand-alone operation
so
that
they can once again be used
as
individual units.
In
order to
so,
simply
follow steps
#1
through
#4
above in "Creating a Cluster" while
omitting
step
#5
.
In
other words, follow
the
steps in creating a"Master"
without
turning
on the additional units
that
would become "Slaves."
Once step
#4
has
been completed, then turn
off
the
unit
in question
as
stated in step
#6.
When you
turn
it
on
the
next time,
that
unit
will
now
operate
as
an independent receiver.

When plugging in
the
Air
DAC
for the first
time
,
it
should turn on in Hunting Mode.The
SKAA
LED
starts
out
illuminated a

AMBER
color (Hunting Mode), and
as
soon
as
any
TX

is
detected
(i.e.,
powered up),
it
turns
to
solid
AMBER.
After approximately one minute,
the
Air
DAC
will recognize and
bond
