OWNER’S GUIDE
C205 C336 CC225
INFINITY CLASSIA™ SERIES
The Infinity Classia™ series of loudspeakers continues the longstanding
Infinity® commitment to accurate sound reproduction. Our patented Ceramic
Metal Matrix Diaphragm (CMMD® ) drivers, precision dividing networks and
rigid, well-braced enclosures combine to deliver uncompromised performance in
any stereo or multichannel home theater system.
In addition, Infinity Classia speakers are magnetically shielded for safe
placement adjacent to a television.
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.
WHAT’S INCLUDED
PLACEMENT
Stereo
Before deciding where to place your speakers, survey your room and think about
placement, keeping the following points in mind, using Figure 1 as a guide:
- For best results, place the speakers 6’– 8′ apart.
- 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 if you also plan to use the speakers for home theater reproduction.
Figure 1. Experiment with speaker placement to obtain the best bass level and stereo imaging in your room.
HOME THEATER
For front-channel use, place one speaker on the left and another on the right,
along either side of the television monitor. Since the speakers are
magnetically shielded, you can place them without worrying about the field
distorting the TV picture.
For surround use, place speakers alongside the listening position.
Final placement depends on room acoustics, availability of space and your
listening preference (Figures 2 and 3).
The CC225 center channel speaker should be placed on top of or directly below
the television and aimed toward the listening area. The CC225 speaker may also
be wall-mounted. See page 3.
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 for your application.
Figure 2. This overhead view shows a typical home theater plan.
Figure 3. This figure shows an alternate layout, which may be more suitable for some rooms.
WALL-MOUNTING THE C205
The C205 is designed to be mounted directly to a wall. Each speaker has two
keyholes on the back, and will require (2) 1-1/2,” #8 wood screws with a .33″
(8.4mm) screwhead fastened to a wall stud. If a wall stud is unavailable,
install an anchor appropriate for a 1-1/2,” #8 screw.
NOTE: The customer is 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.
Step 1.
Mark the positions on the wall where you would like to place the mounting
screws.
Step 2.
Fasten two 1-1/2,” #8 wood screws to the wall using the markings placed in
Step 1 as your guide. Leave an 11/16″ space between the wall and screwhead. If
a wall stud is not available, use an appropriate anchor.
Step 3.
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.
INSTALLING SPIKED FEET
C336
Four metal spikes are supplied for use when using the outboard feet and the
speaker is to be placed on a carpeted surface to decouple the speaker from the
floor and prevent unwanted damping. To insert the spikes, gently lay the
speaker on its back (not its front or side) on a soft, nonabrasive surface,
unscrew the four rubber-tipped feet and store in a safe place.
Each spike then screws into the threaded insert. Make sure all four spikes are
screwed in completely for stability.
NEVER drag the speaker to move it, as this will damage the spikes, the feet,
the wood cabinet itself, and/or the floor. Always lift the speaker and carry
it to its new location.
WALL-MOUNTING THE CC225
The CC225 is designed to be mounted directly to a wall. The bracket has four
holes on the back, and will require (4) 1-1/2,” #8 wood screws with a .33″
(8.4mm) screwhead fastened to wall studs. If wall studs are unavailable,
install anchors appropriate for a 1- 1/2,” #8 screw.
NOTE: The customer is 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.
Step 1.
Attach the wall bracket to the wall at the desired location.
Step 2.
Securely fasten the two cleats to the rear of the speaker, using two included
1/4″-20 panhead screws per cleat.
Step 3.
Carefully slide the cleats on the rear of the speakers over the tabs of the
wall bracket.
WIRING THE SYSTEM
IMPORTANT: Make sure 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 desired, consult your local Infinity dealer about speaker wire and
connection options.
The speakers have coded terminals that accept a variety of wire connectors.
The most common connection is shown in Figure 5.
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 – (black) 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.
Figure 5. This example shows how to connect bare wires to the terminals.
Figure 6. Wiring diagram shows polarity connections for one channel of a stereo or home theater system.
BI-WIRING
C336
The outer connection panel and internal dividing network of the C336 is
designed so that separate sets of speaker cables can be attached to the
lowfrequency transducer and midrange/high-frequency transducer portions of
this dividing network.
This is called bi-wiring. Bi-wiring can provide several sonic advantages and
considerably more flexibility in power amplifier selection.
Single-Stereo Amplifier
Dual-Stereo Amplifier
FINAL ADJUSTMENTS
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. If not, check all wiring connections or consult the
authorized Infinity dealer from whom you purchased the system for more help.
The amount of bass you hear and the stereo-image quality will be affected by 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.
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, there will be more bass output.
Nearby reflecting surfaces can adversely affect stereo-imaging quality. If
this happens, try angling the speakers slightly inward toward the listening
position until the optimal effect is achieved.
CARE OF YOUR SPEAKER SYSTEM
Each Infinity Classia cabinet has a finish that does not require any routine
maintenance. When needed, 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.
In the event that your Infinity speaker needs service, contact your Infinity
dealer or distributor, or visit www.infinitysystems.com for the location of
the nearest service center.
