Attero Tech unD4I Dante 4 Input Interface (UDP 3rd Party Control)

Attero Tech unD4I Dante 4 Input Interface (UDP 3rd Party Control)

The unD4I four input Dante interface is the ideal interface for adding mic / line inputs to a Dante system. The small form factor to the unD4I allows them to be mounted almost anywhere, putting them close to audio sources and minimizing interference-prone analog wiring. The unD4I 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 has two network connections to allow Dante Daisy Chaining. Dante Daisy Chaining further simplifies system infrastructure wiring by allowing multiple unD4Is to use a single CAT 5 home run connection to a network switch. Power can also be daisy chained. The unD4I is powered by either external +24VDC or any PoE network switch. All adjustable parameters, like mic/line gain and phantom power, are software controlled.

Convenient, easy to mount inputs for: Hotel ballrooms, conference / meeting centers, conference rooms, sports facilities, convention centers, and houses of worship.

Front Panel: Gain and Phantom Power Status LEDs - Shows the gain / pad setting and phantom power status for each of the four input channels. Power / ID LED - Indicates power the unit is on, and blinks in response to a software command for unit identification.

Rear Panel: Mic / Line Inputs 1-4 - Balanced and RF filtered inputs. Gains of 0dB, +15dB, +30dB, +45dB (without the Pad), and -12dB, +3dB, +18dB, and +33dB (with the Pad) are selectable via software. +48V phantom power is also selectable via software. RJ-45 Ethernet Connectors - The left RJ-45 connects to an Ethernet switch (PoE or non-PoE) and also provides the DDC input for daisy chained units. The right RJ-45 provides DDC out to daisy chained units. +24VDC Input - Allows the unD4I to be powered if a PoE Ethernet switch is not used. Power Link In/Out - Allows DC power to be daisy chained between multiple units.

Features: 

  • 4 balanced and RF filtered mic / line inputs on 3-pin depluggable connectors
  • 8 mic / line gains to accommodate any analog input level. Gain is individually adjustable per channel via software
  • 802.3af compliant PoE powered to work with any compliant PoE network switch, or an external +24VDC supply
  • +48V Phantom power - powers virtually all types of phantom powered microphones typically used in installed AV systems. Phantom power is switchable per channel via software
  • ID LED allows easy identification of the unD4I with which Attero Tech’s Unify software is communicating
  • Dante Daisy Chaining allows multiple unD4Is to be connected over a single home-run to the Ethernet switch
