Dante

Configuration

- AES67 clocking on both Dante and SOUND4

- select "SAP Advertising" on SOUND4

- 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

Normally just select session from list.

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 AES67, 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

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 only used for connection. Dante device is then "subscribed" to the stream (to the Mcast IP address) forever (no need Controller afterwards).

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.
