MD-4

4-Input, 4-Output analog-auf-Dante Interface mit Kopfhörermonitoring

MD-4-S
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.
