1. Inleiding
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. Sleutel kenmerke
- 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. Opstelling
3.1 Uitpak
Carefully remove the speakers from their packaging. Ensure all components are present and undamaged. Retain the packaging for future transport or storage.
3.2 Plasing
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.

3.3 Die luidsprekers koppel
Koppel die luidsprekers aan jou amplifier or receiver using high-quality speaker cables. Observe correct polarity: connect the positive (+) terminal on the speaker to the positive (+) terminal on the ampluidspreker, en die negatiewe (-) terminaal op die luidspreker na die negatiewe (-) terminaal op die amplifier. The D-412EX features gold-plated machined brass terminals for secure and high-fidelity connections.
- Verseker jou ampdie versterker/ontvanger afgeskakel word voordat enige verbindings gemaak word.
- Unscrew the terminal caps on the back of each speaker and your amplewendiger.
- Insert the bare wire ends of the speaker cable into the corresponding terminals.
- Tighten the terminal caps to secure the wires. Ensure no stray wire strands are touching other terminals, which could cause a short circuit.
4. Operasie
4.1 Aanvanklike aanskakeling
After connecting the speakers, turn on your amplifier/receiver. Start with the volume at its lowest setting and gradually increase it to a comfortable listening level.
4.2 Listening Tips
- Allow a "break-in" period for new speakers. The sound quality may improve after several hours of use.
- Experiment with speaker placement to find the best stereo imaging and bass response for your room.
- Avoid excessively high volume levels for prolonged periods to prevent damage to the speakers and your hearing.
5. Onderhoud
- Skoonmaak: Use a soft, dry cloth to wipe the speaker cabinets. Do not use liquid cleaners or abrasive materials, as they may damage the finish.
- Roosters: The speaker grilles can be carefully removed for cleaning or if you prefer the aesthetic without them. Handle them gently to avoid damage.
- Omgewing: Hou luidsprekers weg van direkte sonlig, hittebronne en oormatige vog.
