FAQ | Which Attero Tech devices support AES67?

Discover which Attero Tech devices offer AES67 compatibility and how to use it.

Answer


In 2017, Attero Tech  introduced a new line of endpoint and interface products that natively support AES67. Any endpoint product that begins with the "unA" prefix utilizes Attero Tech's own AES67 implementation. These products are known to be compatible with QSC Q-SYS Core DSPs and with Dante products running in Dante-AES67 mode (other devices may also be compatible with Attero Tech AES67 devices. Contact Attero Tech for confirmation). 

 

During the course of 2018, AES67 support also became available for endpoint products based on Dante hardware. All Attero Tech endpoint products that begin with the "unD" prefix use Dante hardware and some of those, but not all, support AES67.

 

The following list identifies all Attero Tech products that support AES67 based on Attero Tech's AES67 implementation:

  • unA6IO-BT
  • unAX4I
  • unAX2IO+
  • unAIO2X2+
  • unA6IO
  • Axon A4FLEX
  • Axon A8Mio
  • Axon A4Mio

The following list identifies all Attero Tech products that support AES67 based on the Dante-AES67 interoperability implementation.

  • unD4O (see note)
  • unD6IO (see note)
  • unD6IO-BT (see note)
  • unDIO2x2+(see note)
  • unDX2IO+ (see note)
  • unDX4i  (see note)
  • unHX2D (see note)
  • unDUSB (see note)
  • Zip4 (see note)
  • Zip4-3G (see note)
  • Axon D2i
  • Axon DBU
  • unD32
  • Synapse D32i
  • Synapse D32o
  • Synapse D16Mio
  • Synapse DM1
  • Axon D2FLEXio

 

Note

Check the specific Dante device the unit is using. Units built with an “UltimoX” or “UltimoX4” processor are required to support AES67. Older Attero Tech units built prior to 2018 may have been built with the original regular “Ultimo” or “Ultimo4” which unfortunately cannot and will not support AES67.
