Setting Latency
Latency is the amount of time for a signal to travel across the system to
the outputs of a device. To account for variances in latency time between
devices and channels, Dante has a predetermined selection of latency set-
tings. When the same setting is selected, it ensures that all Dante devices
on the network are in sync.
The latency setting for Dante devices should be set according to the num-
ber of switches in the network.
Use Audinate's Dante Controller software to change the latency setting.
Latency Recommendations

0.25 ms 3
0.5 ms (default) 5
1 ms 10
2 ms 10+

Operating the Control Software over Wi-Fi
When operating the web application over Wi-Fi, it's important to set up
the wireless router properly for best performance. The system employs
several standard-based protocols that rely on multicast. Wi-Fi treats
broadcast and multicast packets differently than general packets for
backward compatibility reasons. In some cases, the Wi-Fi router will limit
the multicast packet transmission rate to a value that is too slow for web
application to properly operate.
Wi-Fi routers typically support 802.11b, 802.11a/g, and/or 802.11n
standards. By default, many Wi-Fi routers are configured to allow older
802.11b devices to operate over the network. In this configuration, these
routers will automatically limit the multicast data rates (or sometimes re-
ferred to as 'basic rate', or 'management rate') to 1-2Mbps.
Note: A Wi-Fi connection can only be used for the control software.
Network audio cannot be transmitted over Wi-Fi.
Tip: For larger wireless microphone configurations, it's recommended to
increase the multicast transmission rate to provide adequate bandwidth.
Important: For best performance, use a Wi-Fi router that does not limit
the multicast rate to 1-2 Mbps.
Shure recommends the following Wi-Fi router brands:
• Cisco
• Linksys
• Apple
