INFINITY
REFERENCE
SERIES
The
Reference
series
of
loudspeakers
continues
the
longstanding
Infinity
commitment
to
accurate
sound
reproduction.
Our
proprietary
CMMD®
(Ceramic
Metal
Matrix
Diaphragm)
drivers,
precision
dividing
networks
and
rigid,
well-braced
enclosures
combine
to
deliver
uncompromised
performance
in
any
stereo
or
multichannel
home
theater
system.
UNPACKING
THE
SPEAKERS
If
you
suspect
damage
from
transit,
report
it
immediately
to
your
dealer.
Keep
the
shipping
carton
and
packing
materials
for
future
use.
PLACEMENT
Stereo
Before
deciding
where
to
place
your
Reference
speakers,
survey
your
room
and
think
about
placement,
using
Figure
1
as
a
guide
and
keeping
the
following
points
in
mind:
•
For
best
results,
place
the
speakers
6
to
8
feet
(1.8
to
2.4
meters)
apart.
Angle
each
speaker
toward
the
listening
position.
•
Position
each
speaker
so
that
the
tweeter
is
approximately
at
ear
level.
•
Generally,
bass
output
will
increase
as
the
speaker
is
moved
closer
to
a
wall
or
corner.
•
Refer
to
the
"Home
Theater"
section
on
this
page
if
you
plan
to
use
the
speakers
for
home
theater
reproduction.

INFINITY
REFERENCE
SPEAKERS
Home
Theater
For
front-channel
use,
place
one
speaker
on
the
left
and
another
on
the
right
of
the
television
monitor.
Angle
your
front
speakers
toward
the
listening
position.
For
surround-sound
use,
place
the
speakers
alongside
the
listening
position.
Final
placement
depends
on
room
acoustics,
availability
of
space
and
your
listening
preference
(Figures
2
and
3).
Place
the
center-channel
speaker
on
top
of
or
directly
below
the
television.
Aim
it
toward
the
listening
area.
NOTE:
An
Infinity
powered
subwoofer
will
add
impact
and
realism
to
both
music
and
film
soundtracks.
Contact
your
Infinity
dealer
for
recommendations
on
subwoofer
models.

CARPET SPIKES- R253 AND R263
Use the included carpet spikes for stability if you are placing your tower
speakers on a thick rug or plush carpeting. The carpet spikes can be
manually screwed into each rubber foot on the base of the speaker.
RUBBER FEET - RC252 AND RC263
Peel the adhesive rubber feet from the included card and apply them to
the bottom of the center channel speaker.

CAUTION: Floorstanding (tower) loudspeakers have a high center of
gravity and may become unstable and tip over during earthquakes or
if they are rocked, tipped or improperly positioned. Consider anchoring
these speakers to the wall behind them, using the procedures and
hardware customary for anchoring bookcases and wall units. You are
responsible for proper installation and proper selection of hardware.
WALL-MOUNTING THE RS152
We have designed the RS 152 speakers to mount directly onto a wall.
Each speaker has two keyholes on the back and will require two 1-1 /2"
(38mm), #10 wood screws fastened to a wall stud.lf a wall stud is
unavailable, install an anchor appropriate for a 1-1 /2': #1 0 screw.
NOTE: You are responsible for the correct selection and use of
mounting hardware (available through hardware stores) that will
ensure the proper and safe wall-mounting of the speakers.
+------+- Keyholes
'
Rubber cushions
Figure 4. RS 152 keyhole location and rubber cushion placement.
Step 1.
Using the included wall template, mark the positions on the wall where you
would like to place the mounting screws.
Step 2.
Fasten two 1-1 /2': #1 0 wood screws to the wall using the markings
from Step 1 as your guide. Leave an 1 /16" (1.59mm) space between
the wall and screwhead.lf a wall stud is not available, use an
appropriate anchor.
Step 3.
To protect wall, attach 4 rubber cushions (included) in suggested
locations.
Step 4.
Place the speaker on the wall by aligning the keyholes on the back of
the speaker to the screwheads on the wall. Once positioned properly, the
speaker should slide down slightly and become secure.

WIRING
THE
SYSTEM
IMPORTANT:
Make
sure
that
all
equipment
is
turned
off
before
making
any
connections.
For
speaker
connections,
use
a
minimum
#16-gauge
speaker
wire
with
polarity
coding.
The
side
of
the
wire
with
a
ridge
or
other
coding
is
usually
considered
positive
polarity
(i.e.,
+).
NOTE:
If
you
are
unsure
about
the
proper
wire
to
use,
consult
your
local
Infinity
dealer
about
speaker
wire
and
connection
options.
The
speakers
have
coded
terminals
that
accept
a
variety
of
wire
connectors.
Figure
5
shows
the
most
common
connection.

This
example
shows
how
to
connect
bare
wires
to
the
terminals.
To
ensure
proper
polarity,
connect
each+
terminal
on
the
back
of
the
amplifier
or
receiver
to
the
respective+
(red)
terminal
on
each
speaker,
as
shown
in
Figure
6.
Connect
the-

terminals
in
a
similar
way.
See
the
owner's
guides
that
were
included
with
your
amplifier,
receiver
and
television
to
confirm
connection
procedures.
IMPORTANT:
Do
not
reverse
polarities
(i.e.,+
to-or-
to+)
when
making
connections.
Doing
so
will
cause
poor
imaging
and
diminished
bass
response.

For
RC263,
R263,
and
R253
speakers,
you
can
choose
either
set
of
terminals.
IMPORTANT:
Do
not
remove
the
metal

from
between
the
two
sets
of
terminals
when
connecting
the
speaker
wires.
BI-WIRE
CONNECTION
-
RC263,
R253
AND
R263
These
speaker
connection
assemblies
have
two
sets
of
input
terminals
that
are
connected
by
metal
jumper
bars.
The
upper
set
of
terminals
is
for
the
midrange/tweeter,
and
the
lower
set
of
terminals
is
for
the
woofers.
This
arrangement
allows
you
to
bi-wire
the
speakers
using
a
single
stereo
amplifier
or
using
two
stereo
amplifiers.
Bi-wiring
can
offer
sonic
advantages
and
more
flexibility
in
power-amplifier
selection
over
a
conventional
single-wire
connection.
Before
bi-wiring
the
speakers,
remove
the
jumper
bars.

FINAL ADJUSTMENT
Check the speakers for playback, first by setting the system volume
control to a minimum level and then by applying power to your audio
system. Play a favorite music or video segment, and increase the system
volume control to a comfortable level.
NOTE: You should hear balanced audio reproduction across the entire
frequency spectrum, from high tones to deep bass. If not, check all
wiring connections or consult the authorized Infinity dealer from whom
you purchased the system.
A number of different factors- including the room's size and shape,
the construction materials used to build the room, the listener's
position relative to the speakers, and the position of the speakers in the
room- will affect the amount of bass you hear and the stereo-image
quality (the placement of sounds in space). Listen to a variety of music
selections and note the bass level. If there is too much bass, move the
speakers away from nearby walls. Conversely, if you place the speakers
closer to the walls, you should hear more bass.
Nearby refiecting surfaces can adversely affect stereo-imaging
quality. If they do, try angling the speakers slightly inward toward the
listening position until you achieve the best possible sound.
(ARE OF YOUR SPEAKER SYSTEM
Each Reference series cabinet has a wood-grain vinyl finish that does not
require any routine maintenance. You may use a soft cloth to remove
any fingerprints or dust. Clean the grille by gentle vacuuming.
NOTE: Do not use any cleaning products or polishes on the cabinet
or grille.
If your Infinity speaker needs service, contact your Infinity dealer or
distributor, or visit www.infinityspeakers.com for the location of the
nearest service center.
