Application Notes: Dante in Corporate AV Installations
Boardrooms, conference rooms, campuses, lobbies — real-world deployment scenarios Corporate AV is among the most practical deployment target for…
Discovery failures, no audio, dropouts, clock errors, AES67, speaker output
Issue 1 — Device Not Appearing in Dante Controller- Check PoE LED on switch port — confirm power
- Controller PC must be on the same VLAN as Dante devices (mDNS doesn’t cross VLANs without DDM)
- Verify IGMP snooping enabled on Dante VLAN
- Test by connecting device to unmanaged switch to isolate VLAN issue
- Check device Web GUI — confirm valid DHCP address on correct subnet
- Confirm subscription is active — solid green checkmark (flashing/red = error)
- Check source input gain on AUD-DTE-ECODE/LINEIN/XLRIN
- Check output volume — for AUD-DTE-2CHAMP verify master volume in Web GUI
- Confirm correct output mode on AUD-DTE-2CHAMP (Lo-Z vs Hi-Z)
- Check for clock error in Dante Controller Clock Status tab
- STP (most common): Enable PortFast on all Dante device ports
- Flow control: Disable IEEE 802.3x on all Dante ports
- QoS: Verify DSCP EF (46) is honored by the switch
- Increase latency to 10ms if multiple switch hops exist (Dante Controller Device View)
- Open Clock Status tab — identify PTP master and devices with sync errors
- “No synchronization” = device not receiving PTP clock. Confirm all are on same VLAN/L2 segment.
- For AES67: switch must support IEEE 1588 PTP and not block PTP packets
- Manually set preferred PTP master if multiple masters cause conflict. Power cycle affected device.
- Enable AES67 mode in Dante Controller → Device View → AES67 tab
- Switch must support IEEE 1588 PTP hardware timestamping
- Verify both devices use the same multicast address range
- Confirm IGMP snooping + querier active for AES67 multicast groups
- Confirm impedance switch correct: Lo-Z (4Ω/8Ω) for direct speakers, Hi-Z for 70V/100V
- Speakers must be on correct terminal: Lo-Z uses 4/8Ω AMP OUT; Hi-Z uses 70V/100V AMP OUT
- Web GUI: master volume above minimum, unit not in auto standby
- Verify Dante subscription is active to the correct amplifier receiver channel
Diagnostic Checklist
✓PoE confirmed — all device switch ports ✓Controller PC on same VLAN as Dante devices ✓IGMP snooping + querier enabled ✓QoS DSCP EF (46) honored ✓STP PortFast + flow control disabled ✓Subscriptions active (green checkmarks) ✓No clock errors in Dante Controller ✓Input/output gain levels checked ✓Correct output mode on AUD-DTE-2CHAMP Need more help?Contact KanexPro support at support@kanexpro.com or 888.975.1368. Have the device model, firmware version (Web GUI), and network topology ready.
