The ratio controls how much the signal is attenuated when it exceeds the threshold value. Higher ratios provide stronger
attenuation. A lower ratio of 2:1 means that for every 2 dB the signal exceeds the threshold, the output signal will only ex­
ceed the threshold by 1 dB. A higher ratio of 10:1 means a loud sound that exceeds the threshold by 10 dB will only ex­
ceed the threshold by 1 dB, effectively reducing the signal by 9 dB.

Networking and Dante

Digital Audio Networking

tm
Dante digital audio is carried over standard Ethernet and operates using standard Internet Protocols. Dante provides low la­
tency, tight clock synchronization, and high Quality­of­Service (QoS) to provide reliable audio transport to a variety of Dante de­
vices. Dante audio can coexist safely on the same network as IT and control data, or can be configured to use a dedicated net­
work.

Switch Recommendations for Dante Networking

In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or router with the
following features:
• Gigabit ports
• Quality of Service (QoS) with 4 queues
• Diffserv (DSCP) QoS, with strict priority
• Recommended: A managed switch to provide detailed information about the operation of each network link (port speed,
error counters, bandwidth used)

Cable Requirements

Always use Cat5E cable or higher.

QoS (Quality of Service) Settings

QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with
heavy traffic. This feature is available on most managed network switches. Although not required, assigning QoS settings is
recommended.
Note: Coordinate changes with the network administrator to avoid disrupting service.
To assign QoS values, open the switch interface and use the following table to assign Dante-associated queue values.
• Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
• Use descending priority values for each remaining packet.
