The Attero Tech unD4I-L four input Dante interface allows you to add mic/line inputs to a Dante system. The addition of four logic inputs and four logic outputs allows easy interface with microphone switches and indicator LEDs. The unD4I-L features four balanced mic/line inputs, each with software selectable +48V phantom power and 8 gain levels.

Front panel indicators show each channel's gain and phantom power status for easy troubleshooting. The unD4I-L has two network connections to allow Dante Daisy Chaining, which further simplifies system infrastructure wiring by allowing multiple unD4I-Ls to use a single Cat5 home run connection to a network switch. Power can also be daisy chained. The unD4I-L is powered by either external +24VDC or any PoE network switch. All adjustable parameters, like mic/line gain and phantom power, are software controlled.
