• Measuring tape and pencil
• Speaker wire (appropriate gauge)
• Wire strippers
• Screwdriver (Phillips head)
• Drill (optional, for pilot holes)

4.2. Location Selection

Careful placement is crucial for optimal sound performance. Consider the following:

• Wall Cavity: Ensure sufficient depth and clear space behind the wall surface.
• Obstructions: Use a stud finder to locate studs, electrical wires, and plumbing. Avoid these areas.

1. Run speaker wire from your amplifier/receiver to each speaker opening. Leave enough slack for easy connection.
2. Strip approximately 1/2 inch of insulation from the ends of the speaker wires.
3. Connect the positive (+) terminal of the speaker to the positive (+) terminal of the amplifier, and the negative (-) terminal of the speaker to the negative (-) terminal of the amplifier. Ensure correct polarity for all speakers in your system.
4. Securely fasten the wires into the speaker's spring-loaded or screw terminals.

1. Carefully insert the speaker assembly into the wall opening.
2. Tighten the mounting screws located on the front baffle of the speaker. These screws will engage the dog-ear clamps that pivot out and secure the speaker to the drywall. Do not overtighten.

4.6. Grille Installation

Once the speaker is securely mounted, align the paintable grille with the speaker frame and gently press it into place until it is flush with the wall surface. The grilles can be painted to match your wall color if desired.

5. Operating Instructions

After successful installation and connection to your amplifier or receiver, operating your Legrand On-Q in-wall speakers is straightforward:

1. Ensure your amplifier/receiver is powered on and set to the correct input source.

3. Enjoy high-quality audio playback through your discreetly installed in-wall speakers.

Your Legrand On-Q in-wall speakers require minimal maintenance to ensure long-lasting performance:

• Cleaning: Use a soft, dry cloth to gently wipe dust from the speaker grilles and surrounding areas. Avoid using harsh chemicals or abrasive cleaners.
• Grille Care: If you have painted the grilles, handle them carefully to avoid chipping the paint. If repainting, ensure the paint is thin and does not clog the grille perforations, which could affect sound quality.
