Infinity QPS1 Owner's Manual

INTRODUCTION Infinity QPS-1 speakers are a pair of mirror-imaged, surround-sound speakers with an advanced quadrapole design that creates a non-specific sound source over a wider-than- usual listening area. This unique surround speaker design provides greater flexibility in speaker placement without sacrificing performance. The QPS-1’s elegant, thin-profile enclosure (in a black or white finish) is made to complement your home furnishings and its integrated display stand provides easy placement on a convenient shelf or table. Or, if you prefer, you can mount the QPS-1 speakers on side or back walls by using the built-in, direct-mount keyhole. Please read the remaining pages before connecting and operating the Infinity QPS-1 speakers. Maximum performance is dependent on following these instructions, as well as those listed in the owner’s manuals of associated components in your home theater system. Save these 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 Finish unpacking the speakers and check the contents. If you suspect damage from transit, report it immediately to your dealer and/or delivery service.

PLANNING YOUR SYSTEM To help plan your home theater system, we’ve included two system applications, as shown in Figures 1 and 2. The first one represents a typical living room where the home theater system is the main focus. In the second application, the furniture is arranged for fireplace viewing and the entertainment center is in a corner. Since QPS-1 surround speakers are a quadropole design, exact placement is not critical. For best results, position the speakers so they are level with or behind the listeners (typically seated on a couch). Place them at or above ear level (28" or 0.7m, depending on the available shelf or wall space). Make sure the speaker marked left (on its rear label) is on the left side (as you face forward), and the speaker marked right is on the right side (see Figure 1). Set each speaker on any convenient shelf or table via a built-in display stand (see Figure 3 on page 4). Or use the built-in keyhole (see Figure 3 on page 4) for a more permanent mounting method.

PLACEMENT AND MOUNTING The Infinity QPS-1 surround speakers are equipped with integral display stands for easy placement on a shelf or table. QPS-1 (Table-Top Placement) Bottom View TABLE-TOP PLACEMENT... WALL-MOUNT OPTIONS... IMPORTANT! Figure 3. Use the built-in keyhole to mount QPS-1 surround speakers on walls. NOTE: Be sure to fasten each #8 x 1 1/2" Phillips-head wood screw into a wall stud before hanging the speaker. For wall-mounting, you can use the speaker’s keyhole (see Figure 3). If you are unsure of how to safely and securely wall-mount a speaker, please ask a home theater or hardware specialist for additional help.

WIRING AND POLARITY... IMPORTANT! Figure 4. QPS-1 surround speakers feature gold-plated terminals that can be connected in several different ways; e.g., banana plugs, spade terminals (not shown) and direct wiring. 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 the connections. Consult the owner’s manuals (included with your amplifier, receiver or television) for connection and operation procedures. QPS-1 speakers have gold-plated terminals that accept a variety of wire connectors (see Figure 4 below). Observe correct polarities when making speaker connections, as shown in Figure 5 (on page 6). Connect each + terminal on the back of the amplifier, receiver or television to the respective + (red) terminal on each speaker. Connect the – (black) terminals in the same way. Do not reverse polarities (e.g., + to - or - to +) when making connections. TESTING THE SPEAKERS After placing and wiring the speakers, turn on audio system power. Follow the instructions (packed with your A/V preamplifier or receiver) to calibrate the Dolby® Pro Logic® or Dolby Digital channels. Most components include a built-in test tone to help you balance the sound levels to all speakers in your system. During calibration, verify that each QPS-1 reproduces the test tone. If not, check the wiring connections and see the Troubleshooting chart (on page 7) for help.

CARE OF YOUR SPEAKER SYSTEM The QPS-1 cabinet does not require any routine maintenance. When cleaning is needed, first make sure power is off, and then use a soft cloth, pre-dampened with a solution of mild detergent and water, to remove any fingerprints or to wipe off dust. DO NOT USE ANY OTHER CLEANING PRODUCTS OR POLISHES. The metal grille can be cleaned with gentle vacuuming.
