• Martin

Affected Products:

• MAC Aura PXL

Summary:

Customers reported that MAC Aura PXL fixtures exhibited intermittent zoom freezes, stepping, and stuttering when controlled via a P3 System Controller receiving Art-Net or sACN from a lighting console.  The issue was most noticeable during slow zoom effects and fade transitions, where fixtures would occasionally become stuck at zoom endpoints (wide or narrow).  Extensive troubleshooting ruled out fixture personality mode, firmware revisions 1.1 and 1.2, network topology, P3 showfiles, P3 software versions, video tracking settings, and speed modes.  The problem could only be reproduced when the signal path included the P3 System Controller.  Operation via direct DMX or direct Art-Net control bypassing P3 resulted in smooth zoom movement.

Resolution:

Engineering investigated the interaction between the P3 input path and MAC Aura PXL zoom control processing.  Several firmware iterations were developed and tested, eventually resolving the issue in the 1.3.0 firmware branch.  Internal testing and customer site validation confirmed that zoom movement operated correctly when fixtures were controlled through a P3 System Controller.  The correction was incorporated into MAC Aura PXL firmware 1.3.0, which was released to customers and resolved the zoom freeze and stepping behavior observed during slow zoom transitions.  

The case was closed following the public release of firmware version 1.3.0 back in November, 2022.
