Attero Tech Brings “Uncomplicated Audio” to ISE 2015

PDF  | Print |  E-mail

Provider of both Dante and CobraNet audio interfaces, Attero Tech brings to ISE a pair of innovative networked audio products to make it cost effective for audio installation to include high performance networking.


Marketing both under the “uncomplicated Audio” logo, Attero Tech will show the unD4I-L, a Dante 4 input interface with logic i/o, and the unDUSB,  a small, cost-effective interface that bridges host USB devices (like computers) directly to a Dante network.

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 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. 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.

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

The unDUSB, an interface that bridges host USB devices, enumerates on USB as a standard stereo sound card, and provides 2 channels from Dante to USB, and 2 channels from USB to Dante. Since the unDUSB uses USB audio drivers that are built-in for Windows and OSX, no additional drivers need to be installed.


Using an unDUSB, any computer program that can make use of a stereo sound card can instantly have input and output access to audio signals on a Dante network. Music, presentation audio, and even audio from collaboration applications like Skype can be used in a Dante system. The unDUSB can be powered by compliant 802.3af PoE devices, from +9VDC to +24VDC external supplies, or from the power link.

This interface is a convenient USB I/O for:


  • Audio and video conferencing - use the in-room Dante sound system with soft codecs like Skype
  • Conference room presentation audio - use the in-roomDante sound system for best fidelity
  • House of Worship/Conference Centers - easy recording of
  • Dante audio to a laptop or desktop application
  • Use any PC or Mac for a BGM music server directly to a
  • Dante audio system
  • Academic/Lecture Hall for easy PC to Dante presentation
  • audio connectivity
