These precautions include, but are not limited to, the following:

• Read these instructions.
•  Keep these instructions.
•  Heed all warnings.
•  Follow all instructions, particularly those pertaining to rigging, mounting, hanging, and electrical connections.
• This professional device needs to be installed by qualified personnel only. As improper installation may cause the unit to fall, resulting in personal injury and/or property damage.
• Take care of the loudspeaker wires; they should be free of damage. Damaged loudspeaker wires may result in poor sound quality, damaged amplifiers, injury, and/or electrical shock.
•  No mains power shall be connected to the loudspeaker, doing so will damage the loudspeaker, and increase the risk of fire.
•  Respect power rating, to prevent damaged loudspeakers, and risk of fire.
• Do not open the loudspeaker or attempt to disassemble the internal parts or modify them in any way. If the loudspeaker appears to be malfunctioning (no sound or distorted sound), if you detect smoke or a strange smell coming from the unit, discontinue use immediately and have it inspected by qualified personnel.
• Use cables of the right gauge, especially for long runs or high-power systems.
• Use cables with clear color indication and maintain polarity throughout the whole system.
• Avoid loud feedback from microphones; this can damage your loudspeaker.
• Clean only with a dry cloth.
• Avoid touching the unit’s sharp metal edge to prevent injury.
• Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
• Only use attachments/accessories that are specified and approved by the manufacturer.
• Install the loudspeaker in a location that can structurally support the weight of the unit and its mounting hardware.
• Tighten all speaker clamps securely. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
• Do not hold the tweeter as a handle to carry the unit; this can damage your loudspeaker.
• Always attach a safety cable to both seismic safety tabs to secure the loudspeaker to the building structure. Please, be guided by applicable building codes here. Otherwise,  the unit could fall down, resulting in personal injury or even death.
• Use only industry-accepted mounting tools and methods.
• Exposure to loud audio levels over a long time can cause severe hearing loss.
• Do not forget to consult the local law directions regarding producing sound in public places.
• Please check the unit’s condition after unpacking. If the outside or the carton box has been damaged, inform your shipper immediately.

Installation instructions

ATTENTION
Apart from Audio NV is not responsible for damages resulting from the negligent installation of any loudspeaker.
WARNING
Please make sure that the mounting structure is capable of safely supporting the loudspeaker’s weight.

1. Use the cutout template to mark the mounting hole.

2. When making the hole in your mounting panel, double-check that there are no cables or any other obstructions behind the mounting panel. Cutting the mounting panel without this check might result in damaged infrastructure or power lines.

3. Insert the two tile rails through the cut hole and place them on the ceiling surface right next to the opening. Insert the tile rail spacers in the hole and clip them on the tile rails.

4. Open the connection box on the back of the loudspeaker and take out the euro block connector. Pull the loudspeaker wires through the mounting hole and connect them to the euro block terminal.
   The use of wire ferrules is strongly recommended when the stranded wire is used.

5. Remove the grille from the loudspeaker. The grille is connected to the loudspeaker frame with a detachable wire. This enables the installer to install the loudspeaker more easily without walking up and down the stairs multiple times. It also serves as a grille safety restraint.

6. Turn the mounting clamps inwards (a) and tighten the screws slightly to make them stay in the inward position (b).

7. Insert the euro block connector in the connection box on the back of the loudspeaker and close the cover. This cover acts as a strain relief plate for the cable and a retainer for the euro block connector. If the installation requires the use of a cable gland, use the knockout of 22mm (0.87 inches) present on the cover.
   WARNING Only use a non-conductive cable gland

8. Insert the loudspeaker into the pre-cut hole and fasten the mounting clamp screws carefully until the loudspeaker sits safely in place. Do not overtighten the mounting clamp screws and make sure the clamps are aligned with the tile rails.

9. Always attach a safety cable to one or both provided seismic safety tabs to secure the back can to the building structure. Please be guided by applicable building regulations in this matter otherwise the unit could fall, resulting in personal injury or even death.
   If the safety cable is too long and the loudspeaker should fall the safety cable may snap as a result of too much strain. We, therefore, recommend installing the safety cable with as little slack as possible.

10.  Set the power selector on the front of the loudspeaker in the required position. This power selector switch makes it very easy and fast to balance an installation since there is no need to remove the loudspeakers from their support panel and move wires to different terminals.
    WARNING
    Set the power tapping prior to applying audio and only change the setting while the audio amplifier is shut off.
    WARNING
    The 16-ohm setting is not compatible with 70-volt or 100-volt line amplifiers!
    WARNING
    The highest 70-volt power setting is not compatible with 100-volt line amplifiers, only with 70-volt line amplifiers.

11. Install the thin-edge grille on the loudspeaker. The grille is held in place by powerful magnets. Out of the box, the loudspeaker’s color is pure white (RAL9010). This white finish complements most decors and does not require further painting.
    However, if the interior design requires a custom loudspeaker finish, these loudspeakers are very easy to paint. Only the speaker grille and trim ring have to be painted. For more information, we refer you to the dealer where you purchased this product.
