SAFE LIMITS OF OPERATION

Polk Audio specifies the recommended amplification range for each of its passive (non-amplified) loudspeakers. Typically that specification will be expressed as a range of power such as 20-200 Watts (per channel). It is important to understand what those numbers mean when choosing a receiver or amplifier for your Polk Audio loudspeakers. The lower number indicates the lowest continuous rated power that will yield acceptable performance in a typical listening environment. The higher number indicates the highest per channel power that should be used with your Polk Audio speakers. That number should not be confused with a “Power Handling” specification and it does not imply that the speaker will safely handle that full amount of power on a long-term basis. We specify a wide range of power ratings because not all electronics manufacturers use the same method for rating power. In fact, high quality lower-rated amplifiers sound better and play louder than low quality units with higher power rating.

Automobile horsepower is a good analogy. Your car probably has far more horsepower than it needs for your daily commute and is likely capable of going well over 120mph (190km/hr). Having that extra power is good for on-ramp acceleration and danger avoidance (like getting away from brain-eating zombies) but that doesn’t mean that it is advisable to operate your car on North American highways at full power and maximum speed for an extended period of time. Just ask your local state trooper if you are in doubt. Similarly, we recommend using amplifiers and receivers with rated power above the power handling limits of our speakers because having extra power available for short term peaks is conducive to better sound quality, maximum dynamic range and effortless high volume output. But we strongly urge you not to use the full power of your amplifier or receiver for daily listening.

Loudspeakers can be damaged when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce. Operation at this level can result in very high levels of audible distortion originating in the amplifier, which can add a harsh, gritty sound to your listening material. If you hear distortion—turn the volume down or risk damaging your speakers. You can damage just about any speaker, regardless of power rating, if you drive an amplifier to or beyond the point of distortion.

PLACEMENT OPTIONS

Atrium Series loudspeakers were created to live and play outdoors. Atriums have a wide dispersion pattern, and are also very efficient. This means your Atrium Series loudspeakers will deliver exceptional sound quality throughout a large listening area. However, if you want high sound levels in an outdoor setting with acoustic characteristics that differ from those of indoor conditions, we recommend multiple-pair setups.

In addition to the placement locations typically used for outdoor loudspeakers, all Atrium Series loudspeakers have built-in stability feet, which allows the loudspeakers to be placed securely on a shelf or other flat horizontal surface.

Please keep in mind that you’ll maximize the useful life of your Atrium loudspeakers by locating them where they’ll receive less exposure to the elements, under eaves for example. When locating your Atrium loud-speakers outdoors, take into account three factors: sound quality, convenience and exposure to the elements.

FIGURE 1: Place the speaker in a corner for more bass output. Bracket attached to side wall.

FIGURE 2: Place the speaker away from eaves and corners for less bass output.

FIGURE 3: Place the speaker close under an eave for more bass output.

FIGURE 4: The Atrium’s built-in stability feet ensure safe, secure placement on a shelf of other flat surface.

PREPARING TO PAINT

Before you paint, you will need:

• A spray can of primer paint (Krylon Sandable Spray Primer #1318).
• A spray can of the paint of your choice. Choose exterior grade paint if you plan to use the speakers outdoors.
• A paperclip or corkscrew (for removing the paintable grille).
• Masking tape.
• Paint mask to cover unpaintable parts (not included). To make an easy paint mask, use the grille as a template and cut a mask from heavy, nonporous Kraft paper.
  1. Separate the parts of the speaker: Remove the brackets and bracket knobs. Remove the grille by carefully hooking it with a bent paper clip and pulling it gently away from the cabinet [figure 5].
     

     

     FIGURE 5: Remove the grille using a paper clip.

  2. Mask off the binding posts on the back of the speaker [figure 6], the end panels and bracket knobs, and carefully mask off the front of the speakers to protect the drivers and baffles while painting [figure 7]. The grille has a logo on it, which you may mask off should you choose not to paint over it.

PAINTING THE CABINET, BRACKET KNOBS and BRACKET

1. Apply two thin coats of primer to the cabinet and knobs. The bracket does not require a primer.
2. Only after the primer is completely dry should you apply the finish color [figure 8].
   

   

   FIGURE 8: After priming, apply thin coats
   of finish color.

3. Do not remove the masking material (not included) until the paint is completely dry.
4. Do not reattach the speaker to the bracket until the bracket is mounted. Try to handle any freshly painted parts as little as possible.

PAINTING THE GRILLE

1. Atrium loudspeaker grilles have an even, protective powder coating. This powder coating is an ideal primer. The grille has a logo pod, which you may mask off or paint right over.
2. Using spray paint, spray two thin coats of finish color [figure 9]. If you’re using a compressor and spray gun, use the finest, most diffuse setting. Be careful not to fill the holes in the grille with paint.
   

   

   FIGURE 9: Paint the grille. Use thin coats of
   spray paint. Do not block grille holes with paint.

3. When the paint is completely dry, carefully fit the grille into its recess so that it just rests on the cabinet. Starting with one corner, work around the speaker and push the grille into the grille notch a little at a time.

Be gentle; the grille may be easily bent by rough handling.

MOUNTING OPTIONS (SAFETY FIRST)

When installing Atrium loudspeakers note the weight of your particular model and the weight bearing tolerance of the material to which you’re mounting the speaker. If you’re not sure of a safe way of mounting your speakers, please consult a professional installer, your authorized Polk Audio dealer or a building contractor.

You’ll maximize the useful life of your Atrium loudspeakers by placing them where they’ll receive less exposure to the elements. If extreme weather conditions are expected, we recommend storing your speakers indoors. Look for the best overall compromise between sound quality, convenience and exposure. Never compromise safety.

The Atrium’s Speed-Lock ™ mounting bracket enables you to mount the speaker either horizontally or vertically. The Speed-Lock bracket holds the speaker in place so you can easily aim the speaker to deliver the best possible sound in a variety of situations. Follow the steps below to safely secure the brackets and speakers.

Installing Atrium Series loudspeakers requires basic skills in using tools such as a drill and screwdriver. If you are in doubt that you possess the necessary skills or tools, consult your Polk Audio dealer, or a professional installer.

Horizontal and Vertical Mounting

1. Verify the material on which you plan to mount the speakers (plaster, drywall, paneling, stone, etc.) can support the weight of the speakers:
   Speaker Weights
   Atrium4 ——————— 3.6lbs / 1.63kg each
   Atrium5 ——————— 4.6lbs / 2.09kg each
   Atrium6 ——————— 5.4lbs / 2.45kg each
   Atrium7 ——————— 8lbs / 3.63kg each
   Atrium8 ——————— SDI 9.7lbs / 4.4kg each
2. Ensure the locations you select do not conceal electrical wiring or plumbing.
3. Before you install the speaker, hold it in the chosen location to make sure it safely clears obstacles such as ceiling, adjacent walls, corners, beams, lighting fixtures and door/window frames.
4. Using the keyhole slots in the bracket as a template, mark the installation location of the two keyhole slots with a pencil. You can do this by removing the bracket knobs on the top and bottom of the speaker and removing the bracket [figure 10].
   

   

   FIGURE 10: Turn the bracket knobs to remove
   the bracket assembly.

5. Position the bracket so that the small ends of the keyhole slots are facing “up” according to the direction of installation.
6. If you are certain there is a stud behind the wall surface, drive #10 screws (not included) through the wall and into the stud [figure 11a].
   

   

   FIGURE 11a & 11b: Use #10 screw for wall stud, use #10 wall anchors and screw for no wall stud.

7. If there is no stud behind the wall at the chosen location, install #10 wall anchors (not supplied) into the wall by following the wall-anchor-manufacturer’s instructions. Always use two wall anchors and two screws per speaker [figure 11b].
8. Drive the screws into the stud or wall anchors, leaving screw heads protruding 1/8″~1/4″ (3mm~6mm).
9. If you’re feeding speaker wire through a hole in the wall behind the bracket, pull this speaker wire through the hole in the bracket before mounting the bracket [figure 12].
   

   

   

   FIGURE 13: Slide the bracket down on
   the screw heads to catch the keyhole slots.

10. Screw the bracket directly into a weight-bearing stud on the mounting surface. Place the screws securely in the smaller end of the keyhole slot. Do not leave screw heads protruding.
    Note: All Atrium loudspeaker cabinets have molded ramps, which guide the speaker bracket onto threaded protrusions to which the bracket knobs attach.
11. Screw the bracket knobs into the protrusions but do not tighten them securely.
12. Secure the speaker to the bracket by sliding the speaker between the bracket arms. The built-in ramps will spread the bracket slightly and guide the ends of the bracket onto the threaded protrusions. A ratcheting system holds the speaker in place and helps you fine tune how you want to aim it. [figure 14].
    

    

    FIGURE 14: Turn the bracket knobs
    to remove the bracket assembly.

13. Secure the loudspeaker to the bracket by tightening the adjusting bracket knobs.
14. Tug gently on the speaker to make certain that the screws and bracket are properly aligned and that the wall anchors are secure.
15. If the bracket is not held snug against the wall by the screw heads, remove the speaker from the wall, drive the screws in a little further and then remount the speaker.
16. Once the speaker is mounted, the bracket knobs can be loosened to “aim” the speaker, and then hand tightened to keep the speaker angled correctly.

VERTICAL MOUNT AIMED 45° DOWN

The Atrium Series mounting bracket is designed so the speakers may be mounted in a vertical 45° downward firing position [Figure 15].

Use an anchoring device that can support the weight of your Atrium model and be sure the material you are mounting the loudspeaker to can support its weight.

RECEIVER HOOKUP

Follow the hookup directions included with your receiver. Strip 1/2″ of insulation from each of the two conductors of the wire to expose the bare metal and twist each of the conductors into a single un-frayed strand (so you have two unfrayed strands).

Note that one of the terminals on the rear of each speaker is red (+) and the other is black (–). Make certain that you connect the wire from the red terminal of your amplifier or receiver to the red terminal on your speaker; and the wire from the black terminal of your amplifier or receiver to the black terminal on your speaker [figure 16]. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency.

ATRIUM8 SDI DUAL INPUT/SINGLE INPUT SWITCH

The Atrium8 SDI has a patented dual input/single input switch. this switch enables the Atrium8 SDI to be used either as a single high-performance stereo loudspeaker, or the left-or-right speaker in a high performance stereo pair [Figure 17].
