[. . . ] Die neuentwickelte PowerMax12 Weichenfunktion (Patents Pending) nutzt Endstufenleistung und die Übertragungseigenschaften der Boxen optimal. Dadurch werden klanglich erheblich bessere Ergebnisse mit geringerem Aufwand erzielt als mit herkömmlichen Frequenzweichen oder Controllern. Der ACONE Controller eignet sich auch exzellent zum Aufbau von Aktiv 2-Weg Instrumentalanlagen für Keyboards, Bass und Drums und vermeidet durch die PowerMax12 Weichenfunktion den in herkömmlichen aktiven Instrumentalanlagen häufig beklagten , , lack-of-punchand-definition". Mit dem erstklassigen Dynamikbereich von über 116dB, einem extrem niedrigen Geräuschpegel und herausragendem Preis-Leistungsverhältnis ist der Einsatz des ACONE Controllers auch in kritischen Anwendungen in der Festinstallation eine bevorzugte Alternative zu herkömmlichen Frequenzweichen und Controllern. Description Meeting the highest requirements of modern audio applications - especially, when it comes to sound pressure level, coverage and sound quality - is only possible when using active multi-component loudspeaker systems which provide the possibility to separately amplify and reproduce the audio signal's individual frequency ranges. [. . . ] One of the essential advantages when using active 2-way systems with additional sub woofers is the fact that the vocals are not divided between several speaker systems. This, in return, offers more convenience when adjusting the sound system. Unlike than with active 3- or 4-way configurations ­ difficult analyzing and measuring of sound fields is unnecessary. Since locating low-frequency sound is merely impossible, simply using monaural sub woofers is absolutely sufficient for smaller stages or rooms. On wider stages it is indispensable to use individual sub woofer systems for both sides. Otherwise, the level differences between bass and treble would result in audible degradation of the overall sound. Of course, adding a centrally located sub woofer might additionally improve the sound quality. The ACONE Controller has been designed to be used in high-performance installations that employ active 2-way systems plus sub woofers. Applications like these also mostly incorporate professional linear power amplifiers like the Electro-Voice P1200, P2000, P3000 or Q44, Q66. When using processor controlled power amplifiers like the Electro-Voice P1250, the processor section is simply switched off. Installing and operating the ACONE Controllers is easy as can be since the user does not need to know any complex detail about crossover functions and equalization. La fonction de Crossover, nouvellement conçue, du PowerMax12 (brevet en cours) optimise la puissance de sortie de l'amplificateur en fonction des caractéristiques du hautparleur. Comparé aux Crossovers ou aux contrôleurs conventionnels, le résultat est une qualité sonore globale améliorée qui est obtenue avec moins d'efforts. Le contrôleur ACONE convient également parfaitement lorsqu'il est intégré dans des applications actives à 2 voies pour le renforcement d'instruments, tels les claviers, les basses et les batteries électriques. La fonction Crossover du PowerMax12 élimine le sempiternel "manque-de-punch-et-de-définition", commun aux systèmes actifs conventionnels utiliser pour le renforcement des instruments de musique. Son excellente dynamique, de plus de 116 dB, son niveau de bruit extrêmement bas et son rapport performance-prix très attractif font du contrôleur ACONE une alternative avantageuse aux solutions de Crossover et de contrôleurs conventionnels ­ même dans le domaine critique des installations permanentes.
