Frequently Asked Questions - SHS-LF Atlas Sound

What ceiling types are compatible with the SHS-LF subwoofer?

The SHS-LF is designed for both drop tile ceilings (2'x2' or 2'x4' tiles) and drywall ceilings with 24" OC stud spacing. For drop tile, place the unit on the tile with sound chamber through a 2.75" hole. For drywall, mount between studs using adjustable rails.

How do I wire the SHS-LF for 70.7V or 100V systems?

Connect the service loop to the provided Phoenix-style connector, observing polarity. Use the tap selector switch to choose the desired wattage tap. Do not use the 8 Ω setting with 70.7V/100V systems. A flex conduit clamp is included; a UL recognized conduit connector must be used.

What is the maximum power handling in 8 Ω mode?

When using the 8 Ω setting, the amplifier output should not exceed 200 W RMS per speaker. Do not overpower in 8 Ω configuration.

Can I paint the diffuser and lens to match the ceiling?

Yes. For drywall installations, leave the paint shield on and install the flange/diffuser after painting. For drop tiles, paint before installation. Use paint suitable for plastic and metal. Do not paint the perforated lens. Custom UV-printing is also available via DesignLab™.

How do I change the diffuser lens?

The unit comes with a 4mm Direct Fire Lens and Grille installed. To change, lift the lens cover edge, unscrew the lens, and replace with the desired lens (8mm Solid or 4mm Direct Fire). Use the included spring to increase open area if needed.

What is the purpose of the suspension ring?

The integrated suspension ring is for safety and seismic code compliance. AtlasIED strongly recommends attaching a support wire from this ring to a suitable anchor point above the ceiling grid, especially in drop tile applications.

Does the SHS-LF come with a warranty?

Yes, AtlasIED provides a 3-year limited warranty for the SHS-LF, covering defects in material and workmanship. Warranty claims require proof of purchase and must be submitted online at atlasied.com/warranty_statement.

Can the SHS-LF be used as a junction box?

No. The connection cavity is not intended for use as a junction box. All conduit must be terminated with a UL recognized conduit connector.

What tools are needed for installation?

For drop tile: a 2.75" hole saw, screwdriver for Phoenix connector, and support wire. For drywall: screws (not provided) for rail attachment, hole saw, and standard electrical tools. A UL recognized conduit connector may be needed.

How do I file a warranty claim for the SHS-LF?

Visit https://www.atlasied.com/warranty_statement, log in or register, select 'Warranty & Returns'. You will need the purchase invoice, date, product name/SKU, serial number (or N/A), and fault description. Allow 2-3 business days for an RA number.

USER MANUAL SHS-LF Atlas Sound

Note: Typical wiring method shall be in accordance with the applicable section of the National Electrical Code, ANSI/NFPA 70 or ANSI/NFPA 72 and CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations.

Recommended Cable Type: Solid/Stranded Copper AWG 18-12 (or equivalent)

Drop Tile Ceiling Installation

1. Remove 2' x 2' or 2' x 4' tile.
2. Determine placement of SHS-LF on the ceiling tile so that hole for the sound chamber leaves room for tile rails to be extended to the ceiling support structure.
3. Mark the cutout circle in the desired location, 2.75" mounting hole.
4. Using a 2.75" hole saw, drill out the hole for the sound chamber.
5. Place SHS-LF on top of the ceiling tile, with sound chamber located in the newly created hole with the tile rails extended to the width of the support structure and leave the paint shield in place to protect the tweeter during installation. Terminate the service loop to Phoenix style connector provided (please note polarity). Flex conduit clamp is provided to facilitate conduit. A UL recognized conduit connector should be used to terminate conduit. Connection cavity is not intended for use as a junction box.
6. Adjust tap selector switch to desired wattage setting or 8^* . (See important note regarding 8 operation)
7. Put the ceiling tile back into the ceiling support structure.
8. Remove the paint shield and install correct diffuser onto the sound chamber based on installation requirements, 8mm Solid with Solid Lens Cover or 4mm Direct Fire with Direct Fire Grille by screwing the Flange onto the sound chamber and then attaching the appropriate lens, solid or perforated.
9. For safety and seismic considerations a suspension ring is integrated into the cover plate of the unit. AtlasIED strongly suggests that a support wire be installed from this support point to a suitable anchor point above ceiling grid. In drop tile applications, this wire can usually be installed from an adjacent tile access near subwoofer location.

Dry Wall Ceiling Installation

Note: AtlasIED recommends installing the SHS-LF before ceiling material is installed.

1. The SHS-LF is designed to fit between 24" OC studs using the integrated adjustable rails.
2. Place the SHS-LF between two studs and adjust the rails until the flat edge is aligned with the stud. Secure the SHS-LF to the stud using three screws (not provided) through the holes pre-drilled in the support rail.
3. Terminate the service loop to Phoenix style connector provided (please note polarity). Flex conduit clamp is provided to facilitate conduit. Connection cavity is not intended for use as a junction box.
4. Adjust tap selector switch to desired wattage setting or 8^* . (See important note regarding 8 operation.)
5. Ensure paint shield remains installed until after the ceiling material has been installed and painted.
6. Remove the paint shield and install correct diffuser onto the sound chamber based on installation requirements, 8mm Solid with Solid Lense Cover or 4mm Direct Fire with Direct Fire Grille by screwing the Flange onto the sound chamber and then attaching the appropriate lens, solid or perforated.

Painting the SHS Diffuser and Solid Lens

The SHS includes a plastic paint shield that is designed to protect the tweeter during shipping and installation. If the installation requires matching the SHS-LF diffuser and lens to the ceiling color, there are three options.

1. In dry wall installations where the ceiling is going to be painted and the SHS-LF is already installed. Leave the paint shield on the sound chamber and do not install the flange, diffuser and lens until painting is completed. Use a paint that is suitable for both plastic and metal to paint the diffuser and lens to match the ceiling color before installing them on the sound chamber. Note: Do not paint the perforated lens.
2. In drop tile ceiling installations using non-white tiles use a paint that is suitable for both plastic and metal to paint the diffuser and lens to match the tile color before installing them on the sound chamber. Note: Do not paint the perforated lens.
3. AtlasIED offers a custom UV-printing service through DesignLab™ by AtlasIED custom match process that is available for an additional fee. This service requires an image or sample submittal of the material to be matched. AtlasIED will then supply a custom flange, trim ring and lens. Learn more at atlasied.com/shs-cust.
