Attero Tech unD4I-L 4-Channel Mic/Line In Dante/AES67 Networked Audio Interface

Part # unD4I-L

Model # unD4I-L

The Attero Tech unD4I-L four input Dante interface is the ideal device for adding mic/line inputs to a Dante system. The addition of 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.

Attero Tech 4-Channel Mic/Line In Dante/AES67 Interface with Logic I/O, PoE

The unD4I-L four input Dante interface is the ideal device for adding mic/line inputs to a Dante system. The addition of 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. Dante Daisy Chaining further simplifies system infrastructure wiring by allowing multiple unD4I-Ls to use a single CAT 5 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.

Applications:

Hotel ballrooms
Conference/meeting centers
Conference rooms
Sports facilities
Convention centers
Houses of Worship

Features

Features
