Delay
Use delay to synchronize audio and video. When a video system introduces latency (where you hear someone speak, and
their mouth moves later), add delay to align audio and video.
Delay is measured in milliseconds. If there is a significant difference between audio and video, start by using larger intervals of
delay time (500-1000 ms). When the audio and video are slightly out of sync, use smaller intervals to fine-tune.
Compressor
Use the compressor to control the dynamic range of the selected signal.
Threshold
When the audio signal exceeds the threshold value, the level is attenuated to prevent unwanted spikes in the output sig­
nal. The amount of attenuation is determined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB above
average talker levels, so the compressor only attenuates unexpected loud sounds.
Ratio
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.
Encryption
Audio is encrypted with the Advanced Encryption Standard (AES-256), as specified by the US Government National Institute of
Standards and Technology (NIST) publication FIPS-197. Shure devices that support encryption require a passphrase to make
a connection. Encryption is not supported with third-party devices.
In Designer, you can only enable encryption for all devices in a room in live mode:

To activate encryption in the web application:
Go to

>

.
Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.
Important: For encryption to work:
All Shure devices on your network must use encryption.
Disable AES67 in Dante Controller. AES67 and AES-256 cannot be used at the same time.
AES67
AES67 is a networked audio standard that enables communication between hardware components which use different IP au­
dio technologies. This Shure device supports AES67 for increased compatibility within networked systems for live sound, inte­
grated installations, and broadcast applications.
The following information is critical when transmitting or receiving AES67 signals:
Update Dante Controller software to the newest available version to ensure the AES67 configuration tab appears.
Before turning encryption on or off, you must disable AES67 in Dante Controller.
