1. Introduktion
The Focal Theva N°3-D is a high-fidelity 3-way floorstanding loudspeaker designed for home cinema systems. It features Dolby Atmos® compatibility, achieved through a dedicated speaker driver positioned on the top of the cabinet. This driver reflects sound waves off the ceiling to create immersive 3D audio effects. This manual provides essential information for the proper setup, operation, and maintenance of your Theva N°3-D loudspeaker.
2. Sikkerhedsinstruktioner

5. Opsætning
5.1 Placering
Optimal placement is crucial for achieving the best sound performance from your Theva N°3-D loudspeakers, especially for Dolby Atmos effects.
- Stereo opsætning: For a traditional stereo setup, place the loudspeakers equidistant from your primary listening position, forming an equilateral triangle.
- Home Cinema Setup: In a home cinema configuration, the Theva N°3-D speakers should be positioned as your front left and right channels. Ensure they are placed symmetrically relative to your screen and listening area.
- Dolby Atmos: The integrated upward-firing driver requires a reflective ceiling. Position the speakers so that the sound from the top driver can reflect off the ceiling and reach your listening position. Avoid placing them under sound-absorbing materials or very high ceilings that might diminish the effect.
- Afstand fra vægge: Experiment with the distance from the rear and side walls. Placing speakers too close to walls can overemphasize bass, while too far can reduce bass impact. A good starting point is 1-2 feet (30-60 cm) from the rear wall.

5.2 Forbindelser
The Theva N°3-D loudspeakers connect to your amplifier using standard speaker cables.
- Kabelvalg: Use high-quality speaker cables of appropriate gauge for the length required.
- Polaritet: Ensure correct polarity (+ to + and - to -) when connecting the speaker terminals to your amplifier. Incorrect polarity will result in poor sound quality and imaging.
- Terminal type: The Theva N°3-D features binding posts that accept bare wire, spade connectors, or banana plugs.
- Amplifier kanaler: Connect the main speaker terminals to the front left and right channels of your amplifier. For the Dolby Atmos effect, ensure your amplifier or AV receiver has dedicated height channels and connect the top-mounted driver terminals to these outputs. Consult your amplifier's manual for specific height channel connections.

- Indbrudsperiode: Loudspeakers typically require a break-in period of several hours of use to achieve their full sonic potential. During this time, the drivers will loosen up and perform optimally.
7. Vedligeholdelse
