ONKYO D-412EX Speaker System Instruction Manual

1. Einleitung

This manual provides essential information for the safe and efficient use of your ONKYO D-412EX Speaker System. Please read it thoroughly before use and retain it for future reference.

2. Hauptmerkmale

• A-Silk OMF Diaphragm: Features a newly developed A-Silk OMF diaphragm, combining the natural characteristics of silk with the strength and flexibility of aramid fiber hybrid molding.
• Advanced Ring-Type Tweeter: Utilizes a ring-type diaphragm and a balanced drive structure with a voice coil positioned between the outer and inner edges of the diaphragm. This design ensures accurate ultra-wideband reproduction up to 100kHz, faithfully covering frequencies up to 20kHz without relying on split vibrations common in conventional dome tweeters.
• Bass Reflex Technology: Incorporates bass reflex technology to enable high-quality bass enhancement within a compact cabinet size. This design releases air vibrations generated inside the cabinet to the exterior through a duct.
• Isolated Mount Method: Employs an isolated mount method to separate the network circuits for the woofer and tweeter units, preventing signal interference between them.
• Gold-Plated Machined Brass Terminals: Equipped with gold-plated machined brass speaker terminals, offering superior conductivity and preventing signal transmission loss and degradation over time.

3.1 Auspacken

Carefully remove the speakers from their packaging. Ensure all components are present and undamaged. Retain the packaging for future transport or storage.

3.2 Platzierung

For optimal sound performance, place the speakers on a stable, level surface. Ensure there is adequate space around each speaker for proper ventilation and sound dispersion. Avoid placing speakers directly against walls or in corners, as this can affect bass response.
