INTRODUCTION
The Infinity US-1 is a compact, efficient 2-way universal satellite speaker system that is ideal
for reproducing home-theater sound for front or rear channels. With their versatile design, US-1
speakers can be placed virtually anywhere on shelves or stands, or mounted on a wall or ceiling,
using the integral 4-way mounting bracket. It has crossholes for mounting and also acts as a door
which hides the mounting terminals. The US-1 Theater Pac contains five US-1 satellite speakers.
To start enjoying your new US-1 Theater Pac, first read and then perform all instructions
listed in this manual, as well as those found in the owner’s manuals of associated components in
your audio system. Save all instructions for future reference. These speakers are covered by
a limited five-year warranty, so save the bill of sale to protect your purchase and aid in any
service-related questions.
UNPACKING THE SPEAKERS
Carefully unpack the speakers. If you suspect damage from transit, report it immediately to your
dealer and/or delivery service. Keep the shipping cartons and packing materials for future use.
Open the accessory pack and verify the following contents:
◆

PLANNING YOUR SYSTEM
US-1 speakers can be used to reproduce sound for either front or surround channels. Before
deciding where to place your US-1 speakers, survey your room and study Figure 1 to determine
the best placement.
PLACEMENT
NOTE: US-1 speakers can be placed directly on a shelf or mounted on a wall, using the built-in
bracket (see Figures 2 through 5).
For front left and right channels, place one US-1 speaker on the left and another on the right,
along either side of the television monitor.
For the center channel, place one US-1 speaker directly on top of, or below, your
television, either vertically or horizontally.
Since the speakers are magnetically shielded, you can place them very close to the TV without
worrying about the magnetic field distorting the TV picture.
For surround left and right channels, place one US-1 speaker on the left and another on the right,
to the side of, or behind the listening area.

SHELF PLACEMENT OF US-1
US-1 speakers can be positioned vertically in two positions on a shelf or stand, as shown in
Figure 2. Set each US-1 flat, with the logo at the bottom and the bracket facing inward.
You can also push the speakers gently back for a 20° tilt.
US-1 speakers can be positioned horizontally in three positions on a shelf or stand, as shown
in Figure 3. Set each US-1 flat, or push the speakers gently back for a 20° tilt. Rotate the logo
to match the orientation of the speaker. To provide a 10° tilt-down angle, loosen the bracket
screw on the rear door with the hex wrench (included) and adjust the bracket to Bracket Open,
Position #1. Tighten the bracket screw when you have reached the desired angle.
NOTE: You may want to route the wires before tightening the bracket screw (see Figure 7 on page 7).

WALL-MOUNTING THE US-1
US-1 speakers can be wall- or ceiling-mounted, as shown in Figures 4 and 5. You can mount the
speakers with #6 wood screws (not included), using the built-in mounting bracket.
Use the enclosed template to mark the desired position of each US-1 on a wall or ceiling.
Locate a stud for secure mounting and use heavy-duty wood screws with long threads. Test
the mounting thoroughly before installation.
To mount the US-1 speaker vertically on a wall, fasten the wood screws (not included) to a
wall stud, leaving a 3⁄16" clearance between the base of the screw head and the wall. If desired,
loosen the bracket screw, adjust the bracket angle, and tighten the bracket screw.
NOTE: You may want to route the wires before tightening the bracket screw (see Figure 7 on page 7).
Then orient the speaker vertically, align the crossholes on the rear of the US-1 with the wood
screws, and slide the speaker down.

WIRING THE SYSTEM
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 at
least #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 positive polarity (i.e., + ). Also, consult
the owner’s manuals that were included with your amplifier, receiver, or television to confirm
connection procedures.
On the back of the US-1, loosen the bracket screw and rotate the bracket to access terminals.
Observe polarities when making speaker connections, as shown in Figure 6. Connect each +
terminal on the back of the amplifier, receiver, or television to the respective + (red) terminal
on each US-1 speaker. Similarly, connect the – (black) terminals in the same way.
Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause
poor imaging and diminished bass response.
After making your connections, route the wires through either hole in the door, as shown in
Figure 7.
NOTE: You may need to loosen the bracket screw to open the door further.
After you finish connecting your system, return the door to the desired angle and tighten the
bracket screw.

OPERATING THE SYSTEM
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 see In Case of Trouble for more help.
When using the US-1 Theater Pac in a Dolby* Pro Logic* home-theater system, make sure
the receiver’s center-channel mode is set to “Normal”. When using the US-1 Theater Pac in a
Dolby Digital or DTS
®
home-theater system, make sure the receiver’s speaker mode is
set to “Small”.
CARE OF YOUR SPEAKER SYSTEM
The US-1 enclosure 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 enclosure or grille.
IN CASE OF TROUBLE
Before consulting your dealer, try these simple troubleshooting steps:
• If the sound quality is distorted, listen to each speaker separately.
• If distortion is present in both, the problem is probably somewhere else in your system.
• If only one channel is distorted, switch the left and right speaker leads at the receiver.
• If the distortion moves to the other speaker, the problem is not in the speaker.
• If you need further assistance, contact your local Infinity retail dealer.
