Dante
See Yamaha Tio1608-D page for an example
Contents
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
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. 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).

Troubleshooting
S4->Dante
Advertised (checkmark under Dante Controller) but no sound (HP greyed) : check clock is AES67. If clock not synched, no sound.
