To access Design Properties, select File > Design Properties while in Design Mode.

PTPv2 Domain

This is the domain that Q-SYS will use whenever the design requires clock synchronization, such as when routing audio to and from Q-LAN RX and TX components (Core-to-Core streaming), AES67 Receiver and Transmitter components, or Q-SYS peripherals. You can also use this property to enable or disable synchronizing with other PTPv2-aware devices on the network. The value must be identical in each design requiring synchronization between Q-SYS Cores.

• Default (0): This is the default, predefined clock domain number (zero).
• Alt 1 (1), Alt 2 (2), Alt 3 (3): These are the predefined, alternate clock domain numbers.
• User (4 - 127): Select this option to specify your own PTPv2 User Domain, from 4 to 127.

QoS Preset

Select the DSCP Quality of Service (QoS) markings to apply to various Q-SYS data types. DSCP markings are used by the network switch to prioritize these data types with other data on the network. For more information, see Q-SYS DSCP Mappings.

• QLAN: (Default) DSCP preset for Q-LAN traffic optimization.
• Audinate: DSCP preset for Audinate (Dante) traffic optimization.
• Manual: Select your own DSCP values.

PTPv2 DSCP Value

In Manual mode, select a PTPv2 DSCP value from 0 to 63. PTPv2 must be the highest priority on your network to ensure that all Q-SYS devices are synchronized correctly. Poor clock sync over the network results in audio and video dropouts.

Audio DSCP Value

In Manual mode, select an Audio DSCP value from 0 to 63. Audio streams (both Q-LAN and AES67) must be the second highest priority on your network. Excessive delay of audio packets over the network results in audio dropouts.
