INTRODUCTION
Niles
once
again
raises
the
bar.
With
our
first
OS
Indoor/Outdoor
models,
we
revealed
a
radical
new
understanding
of
loudspeaker
capabilities.
Niles
original
OS
Indoor/Outdoor
Loudspeakers
are
constantly
praised
for
their
ability
to
deliver
exemplary
reliability
and
outstanding
sound
quality.
These
attributes
have
made
Niles
OS
Indoor/Outdoor
Loudspeakers
the
bestselling
loudspeakers
in
their
class.
The
goal
of
our
new
OS
Indoor/Outdoor
line-up
is
to
raise
this
bar
with
refined
appearance
and
superior
sonic
performance,
once
again
establishing
a
benchmark
by
which
all
others
are
judged.
The
new
Niles
OS
Indoor/Outdoor
Loudspeakers
owe
much
of
their
performance
and
sound
quality
advantage
to
design
elements
pioneered
in
the
award-winning
Niles
DS
Directed
Soundfield™
Loudspeakers.
Their
engineering
advances
come
from
our
integrated
approach
to
driver
and
cabinet
design.
By
integrating
the
woofer
basket
into
the
baffle
of
the
cabinet,
we
are
able
to
increase
the
woofer
cone-area
to
cabinet-width
ratio,
thus
enabling
OS
Indoor/Outdoor
Loudspeakers
to
provide
levels
of
bass
performance
that
substantially
exceed
their
physical
size.
Deeper
and
more
powerful
bass
isn't
the
only
refinement
in
the
new
OS
Indoor/Outdoor
line-up.
A
new
and
modern
style
enables
OS
Indoor/Outdoor
Loudspeakers
to
blend
seamlessly
with
architectural
elements,
both
indoors
and
out.
After
the
installation
is
complete,
you
will
be
astonished
by
the
experience
of
hearing
such
clean
and
powerful
sound
coming
from
such
elegant-appearing
loudspeakers.

WIRING
The
OS
loudspeakers
connect
to
your
receiver
or
amplifier
using
2-conductor
loudspeaker
wire
(see
Figure 3
on
the
next
page).
For
most
applications,
we
recommend
using
16-
or
18-gauge
wire.
For
wiring
runs
longer
than
80
feet
(24.38
meters),
we
recommend
14-gauge
wire.
The
binding
posts
on
OS
loudspeakers
accommodate
up
to
12-gauge
wire
directly.
Larger
sizes
can
be
accommodated
using
spade,
banana,
or
pin
connectors.
When
you
run
wire
inside
walls,
outdoors
or
in
marine
installations,
special
jacketing
or
conduit
is
required
for
a
trouble-free
installation
and
conformation
to
the
local
and
national
building
codes.
If
you
are
not
sure
of
the
correct
wire
jacket
or
type
of
conduit
to
use,
consult
a
professional
audio/
video
installer,
building
contractor,
or
the
local
building
and
inspection
department.
INCORPORATING A VOLUME CONTROL
It's
possible
to
control
the
volume
of
the
sound
at
the
loudspeaker
location.
Plan
to
wire
the
system
so
that
each
pair
of
loudspeakers
has
its
own
volume
control.
Niles
makes
a
wide
range
of
indoor
and
outdoor
volume
controls
with
and
without
muting
capabilities.
Consult
your
local
Niles
dealer
for
more
information.
Volume
controls
are
connected
in
line
with
the
loudspeaker,
so
you
must
connect
the
wire
from
the
amplifier
to
the
volume
control
and
then
from
the
volume
control
to
the
loudspeaker
(see
Figure 4
on
the
next
page).

RECOMMENDED AMPLIFIER
POWER
For
optimum
performance,
we
recommend
amplifiers
with
the
following
power
ratings:
•
For
the
OS
5.5
loudspeaker,
5
to
100
W
per
channel
•
For
the
OS
6.5
loudspeaker,
5
to
125
W
per
channel
•
For
the
OS
7.5
loudspeaker,
5
to
150
W
per
channel
Ironically,
most
loudspeakers
are
not
damaged
by
large
amplifiers
but
by
small
amplifiers.
If
you
are
playing
at
high
volume,
a
small
amplifier
will
run
out
of
power
very
quickly.
When
an
amplifier
runs
out
of
power
it
creates
damaging
"clipping"
distortion.
A
large
amplifier
will
play
at
the
same
volume
without
distorting.
See
OPERATION
on
page
17
for
more
information
about
clipping
distortion.
PLACING LOUDSPEAKERS FOR
THE
BEST
SOUND
QUALITY
An
OS
loudspeaker's
dispersion
pattern
is
very
broad.
This
allows
good
sound
quality
over
an
extremely
large
listening
area.
However,
if
a
single
pair
is
positioned
to
provide
coverage
of
a
very
large
room
or
patio,
you
will
have
"hot
spots"
of
loud
sound
when
you
are
near
the
loudspeakers.
The
best
way
to
avoid
hot
spots
for
a
large
space
is
to
use
several
pairs
of
loudspeakers
evenly
spaced
throughout
the
room.
A
good
rule
of
thumb
is
to
install
a
pair
of
loudspeakers
for
every
200
to
400
square
feet
(18.58
to
37.16
square
meters)
of
listening
area.
Your
local
Niles
dealer
is
a
good
source
for
advice
on
loudspeaker
placement
for
your
particular
installation.

PLACING
LOUDSPEAKERS
FOR
THE
BEST
SOUND QUALITY
(CONTINUED)
When
using
more
than
one
pair,
it
is
usually
best
to
alternate
a
left
channel
and
then
a
right
channel,
so
that
you
have
the
best
stereo
coverage
possible.
The
position
of
the
loudspeakers
and
their
surroundings
play
a
very
important
role
in
how
a
stereo
image
is
created.
You
should
experiment
to
find
the
very
best
position
for
your
loudspeakers.
Here
are
some
guidelines
to
make
the
process
quick
and
easy.

Make
sure
you
are
not
blocking
or
reflecting
the
sound
off
of
furniture
or
other
objects.
You
should
have
a
direct
line
of
sight
with
the
front
of
the
loudspeaker.
To
determine
the
best
position,
measure
the
distance
between
the
ideal
listening
position
and
the
wall
you
plan
to
mount
the
loudspeakers
on.
Try
to
place
the
loudspeakers
so
that
they
are
at
least
one-half
the
listening
distance
apart
(this
maintains
a
large,
pleasant
stereo
"image")
and
less
than
the
entire
listening
distance
(this
avoids
a
"hole-in-the-middle"
effect).
For
example;
if
you
are
ten
feet
back
from
the
wall,
the
loudspeakers
should
be
between
5
and
10
feet
(1.5
and
3.04
meters)
apart
(see
Figure
5).
If
possible,
mount
the
loudspeakers
between
8
and
12
feet
(2.43
and
3.65
meters)
high.
The
less
the
downward
angle
of
the
loudspeaker,
the
further
the
sound
will
carry.
If
the
sound
is
carrying
into
areas
where
you
do
not
want
sound,
try
pointing
the
loudspeakers
more
downward;
this
will
reduce
the
amount
of
sound
further
away
from
the
loudspeaker.
