Overview

P-AVN devices support AES67 audio transport as part of their IPMX-compliant media networking implementation. Interoperability with Q-SYS Core platforms is currently supported through the ST 2110-30 Receiver/Transmitter module available within Q-SYS.

At this time, native AES67 interoperability using the standard Q-SYS AES67 implementation has not been validated. Successful interoperability has been achieved using the SMPTE ST 2110-30 audio stream workflow in Q-SYS.

Requirements

• P-AVN device configured for AES67 audio transmission and/or reception
• Q-SYS Core with:
  • ST 2110-30 Receiver and/or Transmitter components deployed in the design
• Layer 2/3 network supporting:
  • Multicast traffic
  • PTP timing distribution
  • Appropriate QoS settings for media traffic

Configuration Summary

1. Configure the P-AVN Device

1. Enable AES67 streaming on the P-AVN device.
2. Verify the device is synchronized to the network PTP domain.
3. Note the generated SDP information or multicast stream parameters:
   • Multicast IP address
   • Port number
   • Sample rate
   • Channel count
   • Codec (typically PCM)

2. Configure Q-SYS

1. Open the Q-SYS Designer project.
2. Add an ST 2110-30 Receiver component for audio received from the P-AVN device.
3. Import the SDP file or manually configure the stream parameters to match the AES67 stream generated by the P-AVN device.
4. Confirm the stream locks and audio is present within the Q-SYS design.

For audio transmission from Q-SYS to P-AVN:

1. Add an ST 2110-30 Transmitter component.
2. Configure:
   • Sample rate to match the P-AVN receiver requirements.
   • Channel count as required.
   • PTP synchronization enabled.
3. Export or provide the SDP information to configure the P-AVN receiver.

Timing Considerations

Both platforms must share a common PTP timing source. Loss of synchronization may result in:

• Audio dropouts
• Stream lock failures
• Increased latency or jitter

Verify that all devices are participating in the same PTP domain and that network infrastructure supports IEEE 1588 traffic.

Validation

Successful interoperability has been validated using:

• P-AVN AES67 streams
• Q-SYS ST 2110-30 Receiver and Transmitter components
• Common PTP timing source
• Matching sample rate and channel configuration

Known Limitation

Current Q-SYS interoperability with P-AVN devices requires the use of the ST 2110-30 module. Standard AES67 workflows within Q-SYS have not been validated for interoperability with P-AVN devices at this time.

In certain cases there's a firmware inconsistency between Q-SYS and our 1.4.2 firmware, please reach out to our support team to receive the Beta Release that contains the fix for this.

Troubleshooting

Additional Notes

Because P-AVN devices are IPMX-certified, they utilize standards-based AES67/ST 2110 audio transport. Using the Q-SYS ST 2110-30 module provides the most reliable interoperability path and aligns with the underlying transport standards used by both platforms.
