1 Introduction The Opus Ceramique was conceived as an alternative to our award winning original Opus. Designed specifically for moderate sized listening rooms, the Ceramique presents a taught and coherent soundfield, free of stored energy. Staging of exceptional clarity and harmonic structure is achieved through innovations in crossover technology and the use of low mass drivers, all utilizing the same ceramic diaphragm material. “Purity of musical communication”, was the touchstone phrase th

2 Unpacking Instructions Introduction Your Avalon Acoustics loudspeakers were shipped in a heavy-duty crate to ensure their safe arrival. It is recommended to save this crate for possible future use. Due to the weight of the speakers, it will require two persons to un-crate them and position them for listening. Please arrange for your dealer or other friend to assist in this project. Contents The shipping crate contains the following items: • two loudspeaker cabinets • two grille assemblies
Résumé du contenu de la page N° 7
2.1 Opening the Crate The crate features a one-piece top assembly which is fastened to the crate bottom with screws around the lower perimeter. To unpack, remove the screws and lift the upper portion of the crate straight up (this will require two people). Next, slide each speaker part way off of the crate base so that the plastic bag can be unfastened from the enclosure bottom. Stand the speaker up and the bag can be slid off the top. Please refer to Figure 2.1. ` 1. Remove screws. 2. Lift cas

2.2 Installing the Grilles The grille assemblies are behind a panel on the outside of the speaker crate. Remove the screws securing the panel, and then carefully pull the grilles straight out. The grilles are installed with friction fasteners and press into place on the speaker cabinets. Please see Figure 2.2. 1. Remove screwsand panel fromtop of crate.2. Pull grillesstraight out.3. Push grille pins straightinto grille pin sockets. Figure 2.2 - To install the grille assemblies. Orientation of t

2.3 Replacing Grille Pins The grille pins installed on the grille assemblies are fragile and can be easily damaged. Should any of the pins break, you may replace them using the following procedure. 1. Place the grille assembly face-down on a padded surface (a towel or carpeting). 2. Remove the damaged grille pin by pulling it straight out with a small pliers or similar tool. Please refer to figure 2.4. Make sure that the complete pin is removed and that there are no pin fragments left in the

4. Carefully pull the grille cloth away from the frame mounting hole. The mounting hole must be clear of all obstacles during pin installation. 5. Place the exposed end of the grille pin in the open mounting hole. Check to insure that the grille cloth is not trapped between the pin and frame. Use a small hammer and gently tap the new grille pin in place. Then, pull the insertion tool off the new pin and verify that the pin flange is flush with the surface of the grille. Please refer to Fi

3 Wiring Instructions Introduction The crossover is housed in a sealed, non-accessible chamber in the bottom of the speaker cabinet, to minimize the effect of vibration on the components. The Opus Ceramic is equipped with high-quality barrier terminals for connecting the speaker cables. Ring terminals or spade lugs designed for #10 screws are recommended for cable termination. Connecting the Speaker to the Amplifier 1. Place the speaker in its approximate location, then lay the speaker on its

4 Break-in Period Your new Avalon Acoustics loudspeakers have an initial break-in period. They will not perform to their full sonic potential when first installed in your system. This is partially due to a residual polarization of the dielectric materials used in the crossover capacitors and internal 1 wiring. As music is played through the loudspeakers, the electrical signal will gradually anneal these materials. Similarly, the suspensions of the drivers will reach their optimal mechanical pr

5 Maximizing Performance These details are imperative to obtaining optimum results from your Avalon Acoustics loudspeakers. Break-in The break-in period is critical to maximizing sonic performance and should take place before other adjustments (see the discussion on page 13). The break-in should begin with three to six hours of quiet music, followed by 200 to 300 hours of loud and dynamic source material. Grille Assemblies The grille assemblies, with their felt anti-diffraction masks, are int

Toe-In Adjusting the toe-in angle of the speakers is useful in tailoring the sound to best match the characteristics of your system and listening room. When the speakers are facing straight forward, they tend to create a large, expansive sound-stage, painted with broad brush strokes. As they are rotated toward the listening position, the image becomes more compact, with increased focus, creating a greater sense of intimacy. Pointing the speakers inward is also helpful in situations where strong

First Reflection Points Since the ear/brain system tends to integrate the sounds arriving within a 10 millisecond time window, it is important to control the early reflections arriving from the sidewalls to the listening position. A hard-surfaced wall can produce a strong frequency-dependent reflection that can interfere with the reproduced sound-stage, as well as change the perceived tonal balance of the system. Therefore, damping these first reflection points is strongly recommended. Pleas
