Beschreibung
- Niederohmige Ausgänge sowie getrennte 25-, 70- und 100-Volt-Ausgänge für verteilte Audiosysteme
- Rückseitige Gain-Regler für manipulationsgeschützten Betrieb; 2-dB-Schritte ermöglichen schnelle und reproduzierbare Einstellungen.
- XLR-Eingänge und abnehmbare Euroblock-Eingänge
- DataPort V2 zur Verwendung mit DPV2-kompatiblem Signalverarbeitungszubehör (XC-3, SF-3, LF-3) und DSP-3/DSP-4 (mit externem Netzteil)
- Unabhängige, abschaltbare Clip-Limiter reduzieren Verzerrung
- Einstellbare Hochpassfilter (50 oder 75 Hz) schützen Ihre Lautsprecher und verhindern – bei minimalen Auswirkungen auf das Programmmaterial – eine Stromwandlersättigung.
- Anzeigen an der Vorderseite für Netz, Signal und Clipping
- Abgedeckte Schraubklemmen-Ausgänge entsprechend den geltenden Sicherheitsnormen
- Lüfter mit automatischer Drehzahlregelung: leise bei normalen Betrieb, maximale Kühlung bei Bedarf
- Luftstrom von der Rück- zur Vorderseite sorgt für konstante Kühlung des Racks.
- Betriebsarten: Stereo, Bridge-Mono und Parallel
- Umfassende Schutzschaltungen: Gleichstrom, Infraschall, thermische Überlastung und Kurzschluss
- 3 Jahre Garantie sowie optional 3 Jahre mit erweitertem Servicevertrag
