Configuration

⚠️

SOUND4 products are compliant with AES67 standard, which is NOT compatible with Audinate's DANTE protocol. However DANTE products usually feature an AES67 compatibility layer, which has to be enabled.

  • AES67 compatibility mode on Dante
  • AES67 clocking on both Dante and SOUND4. Devices must be synchronized to the same clock.
  • select "SAP Advertising" on SOUND4. This is for DANTE Controller to see the SOUND4 streams, and for the SOUND4 device to see the streams from DANTE devices.
  • Some DANTE devices accept only 1ms packets, L24 (L16 is accepted but does not work : noise). This is the "AES67 Low Latency (Standard)" audio Profile. You may try the "AES67 Very Low Latency" profile with 250µs packets.
  • VLAN : if no VLAN, use default AES67 profiles : No 802.1 tagging. Else must change AES67 Profiles configuration
  • Dante AES67 default Multicast Address Range = 239.69.x.y (69 prefix may be changed in Dante Controller config)

For Dante to SOUND4

On SOUND4 receiver, select LAN Mode = "AES67 SAP DANTE", and you normally just have to select session from the list (SAP advertising must be enabled).

If you don't see the session from the list, you can also configure the reception by Manual setting :

  • on Dante source device you have to retrieve the Multicast IP address of the stream (something like 239.x.y.z). Also try to get the port, it is usually 5004
  • on SOUND4 you have to select LAN Mode = "AES67 Multicast IP", and write down the IP address in the "Session" field, with port if not 5004 (eg "239.193.4.68:5004")
  • two new fields appear that has to be configured according to stream config : "Sample Format" (usually "L24") and "Nb Channels" (usually 2 ; if the stream has more than 2 only the first two will be used)

You should now receive it

Note : this later solution has faster connection time as it does not need to wait for SAP session to be advertised, which can be tens of seconds.

For SOUND4 to Dante :

  • on SOUND4, select "AES67 Low Latency (Standard)" and chose a Multicast IP address that is free, in the Dante AES67 Multicast Address Range (see above). Default port is 5004 if not given
  • Check Stream format in Advanced/AES67 Profiles for "Sample Format" (normally L24) and "Nb Channels" (normally 2)
  • stream should appear on Dante Controller, with a "+" drop-down to select channels. If no "+", SDP is not recognised.
  • on Dante sink device you normally just have to configure this address and port if requested.

Note :

  • Dante Controller is only needed for first connecting time. Dante device is then "subscribed" to the stream (to the Mcast IP address) forever.

S4->Dante

Advertised (checkmark under Dante Controller) but no sound (HP greyed) : check clock is AES67. If clock not synched, no sound on DANTE side.
