HMD8 DSP 24V

8 CH 24 V MARINE AMPLIFIER WITH DSP

Der HMD8 DSP 24V, ausgestattet mit der Hertz Marine DSP-Technologie, bietet eine Fülle neuer Highlights an Hörvergnügen. Die benutzerfreundliche DSP-PC-Software-Oberfläche macht den Setup-Vorgang zum Kinderspiel und nutzt alle Leistungsmerkmale des installierten Lautsprechersystems. Die erstaunliche Leistung von 8 * 85 W oder 4 * 260 W (RMS @ 4Ω) ermöglicht es dem HMD 8DSP 24V, das gesamte Lautsprechersystem zu steuern und Tonnen von kristallklarem Schalldruck in bis zu drei verschiedenen Zonen des Schiffes zu erzeugen. Die Designphilosophie „Power for the Waves“ zeichnet sich durch ein robustes Gehäuse aus extrudiertem Aluminium mit einer mit Korrosionsschutz behandelten Leiterplatte aus, die jahrelangen Hörgenuss auf offenem Wasser garantiert.
