4-Input, 4-Output analog-auf-Dante Interface mit Kopfhörermonitoring
EINGESTELLTES PRODUKT
User Guide
Das MD-4 4×4 Analog-zu-Dante Interface ist ein einfaches, aber hoch-performantes Interface, um analoges Audio mit Dante Audio-Netzwerken zu verbinden.
Vier hochverstärkende Mikrofon- oder Line-Level-Inputs sind für die Verbindung zum Dante Audio-Netzwerk verfügbar.
Zusätzlich können bis zu vier Dante-Signale an den vier analogen Line-Ausgänge ausgegeben werden.
Die jeweiligen Ein- und Ausgänge können flexibel zur Qualiäts- und Pegelkontrolle auf den Kopfhörer-Monitorausgang geroutet werden.
