Description
Die Endstufen der Digital System-Serie von
DYNACORD bieten eine hohe, stabile Ausgangsleistung bei hohem Wirkungsgrad auf hohem Performance-Niveau. Die DSA-Endstufen sind damit
der ideale Antrieb für typische Anwendungen in
der Festinstallation, wie z. B. mit Lautsprechern
der D-Lite, Forum, VariLine und Cobra Familien.
Die Endstufen sind gegen Überhitzung, Überlast,
Kurzschluss sowie Hochfrequenz und Gleichspannung am Ausgang geschützt. Eine Beschädigung
der Endtransistoren durch Rückeinspeisung elektrischer Energie wird durch die Back-EMF Schutzschaltung verhindert. Beim Softstart werden die
Leistungsausgänge über Relais verzögert zugeschaltet. Zusätzlich verhindert eine Einschaltstrombegrenzung das Ansprechen von Netzsicherungen. Durch Einbau eines optionalen RCM-810
Remote Control Moduls ist die Überwachung der
Endstufe und der angeschlossenen Lautsprecher
über die PC-Software IRIS-Net möglich.
DYNACORD Digital System series amplifiers offer
a package of reliable high output power, high
efficiency and legendary pro audio performance.
They are the premium choice as system drive for a
variety of DYNACORD‘s installation loudspeakers
like e.g. D-Lite, Forum, VariLine or Cobra loudspeaker families. Their comprehensive protection
system includes circuitry against overheating,
overload, short circuit, HF and DC as well as backEMF. A soft start circuit compensates mains
inrush current peaks and thus prevents triggering
AC mains fuse when switching on the amplifier.
Loudspeakers are protected by turn-on-delay
relays. Using an optional RCM-810 Remote
Control Module allows supervision of the
amplifier and connected loudspeakers via IRISNet software.
