Bluetooth
Connect
a
Bluetooth
‐
capable
device
such
as
a
smartphone
or
tablet
by
enabling
Bluetooth
on
your
device
and
then
pairing
it
with
Sonica
DAC.
Refer
to
Bluetooth
Connection
in
the
Settings
and
Advanced
Operations
section
on
pages
11
for
pairing
instructions.
You
can
play
music
from
your
device
either
through
its
local
library
or
other
music
apps.
AUX
Audio
Input
You
can
connect
an
audio
device
with
a
stereo
analog
output
into
the
AUX
IN
of
Sonica
DAC
using
a
pair
of
audio
interconnect
cables.
The
input
signal
will
be
digitized
and
made
available
for
streaming
to
other
Sonica
speakers
on
your
network,
and
at
the
same
time
will
be
converted
back
to
analog
via
the
RCA
and
XLR
outputs.
To
select
this
source
as
the
streaming
audio
input
for
your
Sonica
speakers,
select
AUX
IN
as
the
source
from
the
Sonica
app
or
using
the
Source
Selection
screen
on
the
Front
Panel
Display
.
Certain
analog
audio
devices,
such
as
phono
preamplifiers
and
turntables,
might
have
a
separate
ground
wire.
Connecting
the
ground
wire
to
the
ground
terminal
on
Sonica
DAC
is
optional.
If
connecting
the
ground
wire
to
Sonica
DAC
does
not
result
in
lower
noise,
it
is
not
necessary
for
you
to
do
so.
Note
:
Input
signal
from
AUX
IN
passes
through
analog
‐
to
‐
digital
and
digital
‐
to
‐
analog
conversions
before
it
reaches
the
XLR
or
RCA
outputs.
Although
the
signal
quality
is
still
excellent,
this
is
quite
different
than
passing
the
same
signal
through
an
analog
pre
‐
amplifier.
For
this
reason
Sonica
DAC
is
not
recommended
as
a
replacement
for
a
pre
‐
amplifier
for
analog
audio
signals.
