Bedienungsanleitung DYNACORD M212 DATENBLATT

[. . . ] Für den Tieftonbereich kommt dabei eine High-Efficiency Class-H Endstufe zum Einsatz. Durch die konsequente Verwendung der Class-H Technik wird die Verlustleistung, die Netzstromaufnahme und das Gewicht der Endstufe deutlich reduziert. Die Verstärkung des Hochtonbereichs wird über eine separate Endstufe realisiert. [. . . ] Ein PowerCon Netzausgang zum Anschluss eines weiteren aktiven Kabinetts ist ebenfalls vorhanden. Das Audiosignal wird über eine XLR Buchse zugeführt und kann über eine weitere XLR Buchse zur nächsten Box durchverbunden werden. Zwei stabile Tragegriffe und der eingebaute Aluminium Hochständer Einsatz ermöglichen einen bequemen Transport und optimale Aufstellung zum Publikum. DESCRIPTION The MADRAS M212 mid/high frequency range is reproduced by an Electro-Voice ND6 neodymium driver with 3" voice-coil while two Electro-Voice ND12A transmits the bass frequency range. The integrated power amplifier provides discrete low and high range channels, an integrated active frequency crossover and signal processing. Selecting "FULL-RANGE" or "MID-HIGH" operation is possible via switch button. A high-efficiency Class-H power amplifier provides the low range signal. Consequential use of Class-H technology reduces power dissipation, power consumption as well as the power amp's weight noticeably. High range audio signal amplification is realized via a separate power amplifier. Both power amp blocks are convectioncooled, resulting in no disturbing noise from running fans. The power output capacity of 600W (460W + 140W) allows peak sound pressure levels of more than 131dB at lowest distortion rates. The achievable coverage range approximately doubles the scope of conventional passive loudspeaker systems. The wide radiation angle of 80°x 55° eliminates alignment problems inherent to narrow-angled speaker systems. The MADRAS M212 has an extremely linear frequency response. Horizontal and vertical radiation characteristics are outstandingly smooth, which makes the MADRAS M212 resistant against acoustical feedback and therefore especially suitable for highpower monitoring applications. The fully electronic THERMAL PROTECTION prevents the transducers from being damaged by thermal overload. That's what makes the MADRAS M212 equally suitable for a wide range of demanding applications in the rental business.
