INTRODUCTION  
The Infinity Compositions Overture OVTR 1 speaker system is a super-compact, 3-way, full-  
range bookshelf or stand-mounted speaker with an integral powered subwoofer. The OVTR 1  
is ideal for use where space is at a premium. With its wide bandwidth and uniform response,  
it excels in the accurate reproduction of music, but its high efficiency and ability to produce  
realistic sound levels with minimal amplifier power make it equally suited for use in the finest  
home theater system.

PLANNING YOUR SYSTEM  
Before deciding where to place your Compositions Overture OVTR 1 speakers, survey your  
STEREO PLACEMENT...  
room and keep the following points in mind:  
The OVTR 1 includes a side-firing woofer that requires a minimum 2" (25mm) clearance  
from an object, shelf, or wall, whether placed vertically or horizontally, on a bookshelf or  
stand (see Figure 1).  
NOTE: The stand must be large enough to fully support the speaker.  
For vertical placement, make sure the woofers are facing toward or away from each other.  
For stability, install the enclosed feet (see Installing Feet and Grilles on page 5).  
For best results, try placing the speakers closer together than the distance to the listening area.  
Refer to Figure 2 when placing speakers for best bass level and stereo image (also see  
Operating The System on page 7).  
Wall or  
Other Object

sound, as shown in Figure 3:  
For front left and right channels, place one OVTR 1 speaker on the left and another on the  
right, on bookshelves or stands, along either side of the television monitor.  
For surround left and right channels, place one OVTR 1 speaker on the left and another on  
the right, on bookshelves or stands, behind the listening area.  
For center channel use, place one OVTR 1 speaker in the horizontal position on top of or  
below the television monitor.  
Since the speakers are magnetically shielded, you can set them in very close without  
worrying about the field distorting the TV picture.  
NOTE: Contact your local Infinity dealer about adding a subwoofer to your system for deep bass  
impact on sound effects and music.

INSTALLING FEET AND GRILLES  
Compositions Overture OVTR 1 speakers include two types of feet for vertical or horizontal  
placement on a shelf, table, or speaker stand.  
VERTICAL PLACEMENT...  
To insure proper woofer firing, temporarily position the speakers so that the woofer grilles face  
each other. On each molded foot, peel the backing from the self-adhesive tape and press each  
foot into its respective slot, as shown in Figure 4. Insert a grille into each speaker, so the logo  
is nearest the foot. Flip each speaker over and place them in your system.

HORIZONTAL PLACEMENT...  
Place two small self-adhesive feet on each speaker bottom, as shown in Figure 5. Depending on  
where you plan to put the speaker (e.g., TV top), place two large self-adhesive feet 4 to 6 inches  
away (refer to Figure 5). Insert a grille into each speaker, so the logo is nearest the foot. Flip  
each speaker over and place them in your system.

WIRING THE SYSTEM  
TURN OFF ALL POWER...  
IMPORTANT!  
After placing the speakers, you are ready to connect your system. First turn off all audio system  
power. Use high-quality speaker wire to make your connections. For speaker connections, use  
#18 gauge speaker wire (or #16 for runs over 25 feet) with polarity coding. The side of the wire  
with a ridge or other coding is usually considered negative polarity (i.e., – ). Also, consult the  
owners manuals that were included with your amplifier, receiver, or television to confirm  
connection procedures.  
If your system includes a Dolby® Surround Pro Logic® or AC-3® preamplifier or A/V  
receiver, set the center-channel mode to NORMAL. This will route the low frequencies  
(below 100Hz) away from the center-channel speaker to the front left and right speakers.  
Observe polarities when making speaker connections, as shown in Figures 6 and 7 below.  
Connect each + terminal on the back of the amplifier, receiver, or television to the respective  
+ (red) terminal on each OVTR 1 speaker. Similarly, connect the (black) terminals in the same way.  
IMPORTANT!  
Do not reverse polarities (i.e., + to - or - to +) when making connections. Doing so will cause  
poor imaging and diminished bass response.

OPERATING THE SYSTEM  
For your convenience, the system is fitted with a power on/off switch. Once the system is  
turned on, it will automatically go into a standby mode. Once an audio signal is present, the  
system will automatically turn on. It will revert to standby (drawing only 7 watts) when audio is  
absent for a minimum of 90 minutes. A dual-color “Power On” LED (see Figure 8 below) glows  
red when the amplifier is in the standby mode and green when the amplifier is on.  
If you plan to leave for an extended period of time (e.g., vacation), switch the system off  
(or unplug the AC power cord).  
IMPORTANT!  
IMPORTANT!  
This product is designed for (USA) 120 Vac use only. Do not connect it to any other  
line voltages.  
This product is fitted with a 3-prong grounded power cord. Do not use without ensuring the  
outlet is grounded.  
POWER  
ON...  
1. After speaker wiring has been completed, connect each speakers AC power cord to  
the nearest AC receptacle. You should see an LED illuminate, indicating the amplifier is  
on (see Figure 8 below). If not, verify the AC outlet is delivering power or refer to  
Troubleshooting on page 9.  
CHECKING PLAYBACK...  
2. Check the speakers for playback by first setting the audio system volume control for a  
minimum level, and then applying power to your system. Play a favorite music or video  
segment and increase the volume control to a comfortable level.  
NOTE: You should hear balanced audio reproduction across the entire frequency spectrum. If not,  
check all wiring connections and refer to the “Troubleshooting” section on page 9 for more help.

OPERATING THE SYSTEM (CONTD)  
3. Listen to a variety of music selections and note the bass level. If you feel there is too much  
bass, you can reduce it by adjusting the BASS control from the “normalcenter-detent  
position towards the MIN setting (see Figure 8 on previous page). Conversely, if you want  
more bass output, rotate the level control towards the MAX setting.  
NOTE: The amount of bass you hear 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. If there is too much bass, move  
the speakers away from nearby walls. Conversely, if you want more bass, place the speakers closer  
to the walls (also see Figure 1 on page 3).  
JUDGING BASS LEVEL...  
4. For safety reasons, the side grille is bonded in place. Please do not attempt to remove.  
Potential shock hazard.  
REPLACING THE FUSE  
Compositions Overture OVTR 1 speakers each use a built-in fuse to protect the subwoofer  
amplifier. To replace a fuse with a new one (see enclosed spare), perform the following procedure:  
1. Switch off the speaker and unplug the power cord. Then turn the speaker around to access  
the fuse holder on the rear panel (refer to Figure 9 below).  
2. Using a small flat-blade screwdriver, place the tip in the indent and turn the fuse cap  
counterclockwise.  
3. Remove the old fuse and replace it with a new one having the same value and rating,  
a 2AG 3A SB 250V fuse.  
IMPORTANT!  
Do not substitute the blown fuse with another fuse value or rating. Doing so will void  
the warranty.  
4. Insert the cap holding the new fuse into the holder and turn clockwise to lock it.  
5. Rotate the speaker to its original position. Then plug the speakers AC power cord back into  
the nearest AC outlet.

CARE OF YOUR SPEAKER SYSTEM  
The dark grey metallic finish does not require any routine maintenance. When needed,  
use a soft cloth, dampened with water only, to remove any fingerprints or to wipe off  
dust. Clean the grille by gentle vacuuming or with a damp cloth.  
NOTE: Do not use any cleaning products or polishes on the cabinet or grille.  
For maximum acoustic transparency, the grille uses a lightweight structure that needs to  
be handled with care for removal. To remove the grille, gently pull on the corners to  
unfasten the frame from the cabinet. To replace it, make sure to align the frame pins first  
and then gently snap the frame into place. Never force the grille frame onto the cabinet.

LIMITED FIVE-YEAR WARRANTY  
Who is protected by the warranty?  
Your Infinity warranty protects the original retail purchaser and all subsequent owners for a period of five (5) years (parts and labor) for all speaker  
components, and one (1) year (parts and labor) for all electronics, from any failure as a result of an original manufacturing defect so long as:  
(1) your Infinity loudspeakers were purchased within the fifty states of the U.S.A. or by military personnel from an authorized military outlet and  
(2) the original dated bill of sale is presented whenever service is required during the warranty period. This warranty does not apply to products  
purchased elsewhere; other purchasers should contact their local Infinity distributor for warranty information.  
What does the Infinity warranty cover?  
Except as specified below, this warranty covers all defects in original materials and workmanship. The following are not covered: damage caused  
by accident, misuse, abuse, neglect, product modification; damage occurring during shipment, damage caused by failure to follow instructions in  
the owners manual, including failure to perform recommended periodic or routine maintenance; damage resulting from repairs by someone not  
authorized by Infinity; claims based upon any misrepresentations by the sellers; and any Infinity product on which the serial number has been  
altered, defaced or removed.  
Who pays for what?  
During the period of this warranty, subject to the above conditions, Infinity will pay all of the labor and material expenses to repair a warrantable  
defect.  
How can warranty service be obtained?  
In the event that your Infinity loudspeaker should require service, you should first contact the Infinity dealer from whom the product was  
purchased or, if this is not practical, contact Infinity directly (ATTN: Customer Service) at 20630 Nordhoff Street, Chatsworth, CA 91311  
(818) 407-0228. We may direct you to an authorized service center for Infinity products or ask you to send them to us for repair. In either case,  
you will have to present your original bill of sale to establish warranty coverage.  
Do not send your speaker to us without prior authorization from our Customer Service Department. You are responsible for transporting your  
product to either Infinity or an authorized service center and for payment of all shipping charges; however, Infinity will pay the return shipping  
charges (in the event you return the product to us) if the repairs are covered by warranty. If you experience difficulty in transporting your product  
or are in need of packing materials, please advise us and we may be able to suggest alternative procedures and/or provide adequate packing  
materials.  
LIMITATION OF IMPLIED WARRANTIES: All implied warranties, including fitness for a particular purpose and merchantability are limited in

any kind. Our liability is limited to the repair or replacement, at our option, of a defective product.
