The Attero Tech unDX4I Audio Interface is a cost effective multi-IO wall box. The unDX4I features four balanced mic/line XLR inputs and two balanced line outputs on a Phoenix connector. All inputs and outputs can be used simultaneously and all audio channels are available separately. The unDX4I is designed to fit into most dual gang US junction boxes and is PoE enabled, so all connectivity (power and data) is provided by a single CAT-5 cable.  The unDX4I’s size and IO density make it easy to put AES67 connectivity wherever it’s needed near the audio source or sink thereby eliminating costly and interference prone analog wiring.

Attero Tech unDX4I Applications:

  • Easily accessible microphone audio interface for presentation audio systems in meeting spaces, classrooms, theaters and hospitality venues.
  • House of worship AES67 connectivity for musicians and worship leaders
  • Conveniently located audio network I/O for portable AV systems inconvention spaces and hospitality venues

Attero Tech unDX4I Features:

  • Small form factor, can be unobtrusively located nearanalog sources or sinks
  • 4 balanced XLR mic/line inputs on the front panel,and 2 side mounted balanced line outputs on Phoenix-style depluggableconnectors
  • 802.3af compliant PoE powered to work with anycompliant PoE network switch
  • Four input gains accommodate common line levels,phantom power and dynamic mics.  Input gains are adjustable via softwareon a per input basis
  • +48V Phantom power per channel -powers virtually alltypes of phantom powered microphones typically used in installed AV systems
  • ID LED allows easy identification of which unAX4IAttero Tech’s Unify software is communicating with
  • The balanced line outputs can be wired to any passiveXLR plate such that 4 XLR inputs and 2 XLR outputs are available in a 3-gangUS wall space.
