Introduction
NuForce Air
DAC's
wireless technology lets you stream music from your
computer
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 a consistent 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.

About the Air
DAC
and
SKAA
wireless technology
With Air DAC, you don't move to the
music-the
music moves with you.
The Air
DAC
Wireless System
is
a combination 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 meter range, 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
transmitter
can
send audio
to
four
receivers, and each receiver can connect
to
as
many
as
four
transmitters.
Just link
your
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.

Air DAC/TX User Setup
There
are
numerous ways
that
the Air
DAC
I
TX
system can be configured. Here
are
afew guidelines
to
help you 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 whatever type
of
system you
might
be considering.
Quick Start 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
your goal, 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 first
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 interconnect cables
to
an
unused
input
of
your
home
stereo system (or other amplifier/speakercombination).
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 for the radio signal coming from the
iTX
transmitter connected
to
your
iPod. Once
it
detectsthe 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
manually add 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 for
the
sound
of
music playing through the speakers.
If
you hear music, turn the stereo
system
up
to
the
desired listening level. Ifyou
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
A cluster
is
a
method
whereby several Air
DAC
units can be combined in away that allows one
unit
to
be in control
of
up
to
three others.
In
such asystem, 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
of
the
Slave
units will then switch
to
the same source. Ifa new

nu
FDICE
source
is
desired at a future 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
/Amplifier
I
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
apractical
option.
In
that
case,
you would assign one Air
DAC
unit
to
each amplifier and
use
onlythe 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 amplifier
I
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 amplifier
I
speaker system
to
the
minimum
position and then
turn
on the
AC
power.
9)
Slowly
turn
up
the
volume
of
each amplifier
I
speaker system
to
a 9 o'clock position.
1
0)
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 1
0.
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 aCluster" while
omitting
step
#5.
In otherwords,
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
nexttime,
that
unit
will
now
operate
as
an
independent
receiver.
Air
DAC
I
SKAA
CONTROL
GUIDE
Each
Air
DAC
I
SKAA'"
receiver
uses
a Green List
to
keep track
of
your favorite transmitters (up
to
ten
of
them). Hunting
through
yourGreen List for your favorite transmitters
is
signaled by aGreen
LED.
Your
receiver
can
also explore
to
find new transmitters. Exploring
is
signaled by
an
Amber LED.Ifyour
receiver
has
two
or
more wireless
pieces-
for example, a leftspeaker and a
right
speaker-
we call
that
a Cluster.
Each
Cluster
uses
only one Green List.In
that
way, all
of
its pieces perform
as
one.You
can
command
SKAA
by using the
SKAA
Button (the

Troubleshooting
Factory Default Setting:
10
When plugging in the Air
DAC
for the first time,
it
should turn on in Hunting Mode.
The
SKAA
LED
starts
out
illuminated a
dim
AMBER
color (Hunting Mode), and
as
soon
as
any
TX
transmitter
is
detected
(i.e.,
powered up),
it
turns
to
solid
AMBER
.After approximately one minute, the Air
DAC
will recognize and
bond
with
the signal coming from the
TX
transmitter and the
LED
will turn solid
GREEN.
Once bonded,
that
TX
transmitter will automatically be added
to
the Air
DAC's
Green List
of
favorite devices.
In
the event you are
not
able
to
get sound through your system, make sure
that
all interconnect cables
are
in
good
condition and properly connected, with all powerturned on, and that volume levels
are
appropriately set. You should also check to make sure
that
your batteries
are
fully charged in any
portable device you're using.
Problem: Not responding
to
my clicks on the
SKAA
button.
Solution: Clicks should be fast and rapid,
without
pauses.
Problem: No sound
but
the

is
lit.
Solution: Check the Air

LED
color.
If
AMBER
or

(which means
it
is
getting
a wireless signal),
THEN
check
to
make sure that:

is
set correctly
0 The

is
properly inserted
0 The Windows Audio Driver points
to
