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).

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
owner’s 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 speaker’s 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 (CONT’D)
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 “normal” center-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 speaker’s 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:

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 owner’s 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.
