LANNINGYOURSYSTEM

Infinity Primus™Series

The Primus Series of loudspeakers continues Infinity’s longstanding commitment to accurate sound reproduction. Our proprietary Metal Matrix Diaphragm

™

(MMD™) drivers, precision dividing networks and rigid, well-braced enclosures combine to deliver uncompromised performance in any stereo or multichannel home theater system. In addition, Primus Series speakers, except for the powered subwoofers, are magnetically shielded for safe placement adjacent to a television.

Unpacking the System

Carefully unpack the system. If you suspect damage from transit, report it immediately to your dealer and/or delivery service. Keep the shipping carton and packing materials for future use. Open the package and verify the following contents:

LACEMENT

WALL-MOUNTING THE SATELLITES

NOTE: The satellite speakers can be placed directly on a shelf,

or mounted on a wall using optional wall brackets.

Left and Right Front Channels

For left and right front channels, place one satellite to the left and another to the right of the television, as shown in Figure 1. Since the speakers are magnetically shielded, you can place them very close to the TV without worrying about the magnetic field distorting the picture.

Center Channel

For the center channel, place the speaker directly on top of, or below, your television. Use a shelf if the television does not provide a stable platform.

Surround Channels

For left and right surround channels, place one speaker on the left and another on the right, to the side of or slightly behind the listening area.The surround speakers should be mounted at a height of between 1.2 and 2 meters.

Subwoofer

Since the installation of a subwoofer can be somewhat more complicated than installing full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to installation, it is advisable to call either your dealer or Infinity’s Customer Service Department for advice.

The Primus HCS allows the use of optional wall brackets (UNI-WB) using the threaded insert located above the terminal panel (refer to figure 3)..ker on the wall by aligning the keyhole on the back

of the speaker to the screwhead on the wall. Once positioned properly, the speaker should slide down slightly and become secure.

Figure 3.

Threaded insert

The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with the satellite speakers. Setting the volume of the subwoofer in relation to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer’s volume level too high will result in an overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer.

Here are several additional facts on installation that may prove useful. It is generally believed that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical.While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirectional, the fact is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location. Placement will depend upon your room (for example, whether or not your room permits placement of the subwoofer near either satellite) and the amount and quality of bass required.

ENTER ANDSATELLITESPEAKERCONNECTIONS

Turn Off All Power

After placing the speakers, you are ready to connect your system. First, turn off all audio-system power.Use high-quality speaker wire with polarity coding to make your connections.

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 or receiver to confirm connection procedures.

Satellites

Observe polarities when making speaker connections, as shown in Figure 4. Connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker. 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. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment.

Center Channel

Observe polarities when making speaker connections, as shown in Figure 5. Connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on the speaker. Connect the – (black) terminals in the same way.

Important!

Do not reverse polarities (i.e., + to – or – to +) when making

connections. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment.

Figure 4. Wiring diagram shows polarity connections

for one channel of a home theater system.

Figure 5.The satellites and center channel speaker feature terminals that can be connected in several different ways: e.g., spade terminals and direct wiring (as shown here).

A Few Suggestions

We recommend that you do not operate your speakers or subwoofer with the bass, treble and loudness controls set to full boost.This will place undue strain on your electronics and speakers and could damage them.

The volume control setting on your processor/preamp or receiver is not a specific indication of the overall loudness level of the speakers.The only important consideration is the loudness level at which the system can be played, regardless of where the volume control is set.

Always turn down the volume control setting on your processor/ preamp or receiver when changing a cassette or CD, or switching inputs to AM or FM operation. Excessively loud transients (clicks or popping sounds) can damage the satellite speakers and possibly the subwoofer.

Important!

Whenever changing cables, pulling plugs, etc.,ALWAYS TURN OFF ALL EQUIPMENT, including the subwoofer.

CHOOSE THE SUBWOOFER CONNECTION THAT IS MOST SUITABLE FOR YOUR RECEIVER/PROCESSOR

If you have a Dolby* Digital or DTS®receiver/processor with a low-frequency-effects (LFE) or subwoofer output:

If your receiver/processor does not have subwoofer outputs for the left and right channels or an LFE output:

If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output:

Connect speaker wire from your receiver/amplifier to your speakers and subwoofer using two sets of speaker wire.

PERATION

Surround Modes (Using LFE or line level inputs to subwoofer)

When using the Primus HCS in a Dolby Digital or DTS home theater system, make sure all speakers are set to “Small”. When using the Primus HCS in a Dolby Pro Logic* home theater system make sure the receiver’s center channel mode is set to “Small”.

Some Dolby Digital-equipped receivers/processors offer different setup options for each source or surround mode, e.g., CD-stereo, videotape, Dolby, Pro Logic. In each case,follow your equipment’s instructions to ensure that the subwoofer output is turned on and that the speakers are set to “Small”in each mode.

Surround Modes (Using high level inputs to subwoofer)

When using the Primus HCS in a Dolby Digital or DTS home theater system, make sure all speakers are set to “Large” in your receiver set-up menu.When using the Primus HCS in a Dolby Pro Logic* home theater system make sure the receiver’s center channel mode is set to “Large”.

Power On

Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver.

Initially set the Subwoofer Level Control ¡to the“MIN”position.

Turn on the subwoofer by pressing the Power Switch •on the rear panel.

Turn on your entire audio system and start a CD or movie soundtrack at a moderate level.

Important Note: The Primus Subwoofer includes an Auto-On/AutoOff circuit. During periods of normal use, the power switch should always be left on. It should only be turned off during extended periods of nonoperation, e.g., when you are away on vacation.

Adjust Gain

Turn the Subwoofer Level Control ¡up about half way.If no sound emanates from the subwoofer, check the AC-line cord and input cables.Are the connectors on the cables making proper contact? Is the AC plug connected to a “live”receptacle? Has the

Power Switch •been pressed to the “On” position? Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.

Set the overall volume control of the receiver/processor to a comfortable level.Adjust the Subwoofer Level Control ¡until

you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud,

adhering to the belief that a subwoofer is there to produce lots of bass.This is not entirely true. A subwoofer is designed to extend the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural.An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive.

Crossover Adjustment

NOTE: This control will have no effect if the LFE Input ¢ is

used. If you have a Dolby Digital or DTS receiver/processor, the Low-Pass Frequency is set by the receiver/processor. Consult your owner’s manual to learn how to view or change this setting.

The Crossover control ™ determines the highest frequency at which the subwoofer reproduces sounds. For the Primus HCS, it is recommended that this control be set at 120Hz.

Phase Control

The Phase Switch £ determines whether the subwoofer speaker’s piston-like action moves in and out with the main speakers, 0˚, or opposite the main speakers, 180˚. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position.Adjust the phase switch to maximize bass output at the listening position.

Final Positioning

After correctly connecting the Primus HCS system and verifying that both the subwoofer and all satellite speakers are playing, it is time to optimize the system for your particular listening room. Earlier, you placed the subwoofer in its general location. Finding the exact location for optimum performance sometimes only involves moving the speakers up to a few inches in any direction. We urge you, therefore, to experiment with placement, if possible, until your speakers deliver their full potential.

AINTENANCE ANDSERVICE

The speaker and subwoofer enclosures may be cleaned using a soft cloth to remove fingerprints or to wipe off dust.

The grilles may be gently vacuumed. Stains may be removed with an aerosol cleaner, following its instructions.Do not use any solvents on the grille.

All wiring connections should be inspected and cleaned or remade periodically.The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum.

If a problem occurs, make sure that all connections are properly made and clean. If a problem exists in one loudspeaker, reverse the connection wires to the left and right system. If the problem remains in the same speaker, then the fault is with the loudspeaker. If the problem appears in the opposite speaker, the cause is in another component or cable. In the event that your Primus HCS ever needs service, contact your local Infinity dealer or distributor.
