Software Upgrade for SFX 4104 Receivers on June 29

Back to top

Thanks to the feedback we received regarding audio issues with the IDC SFX 4104 Pro Audio receivers, the PRSS deployed a software patch on June 29, 2012. The upgrade is intended to address reports of stuttering and/or dropped audio as well as issues with the Livewire outputs on the new units.

If your station’s 4104 Pro Audio receivers were connected to the satellite at the time of the deployment, they should have downloaded the fix automatically, rebooted themselves and then come back on-line. If your new receivers were not connected at the time of the deployment, then they will not receive the software patch until you have connected them. We strongly urge all stations to connect the new receivers to the satellite immediately so that they can download the patch.

It is also important to note that the automatic reboot, which the SFX 4104s automatically do following the download, takes the unit off-line for approximately one to two minutes. For this reason, stations should have their legacy IDC SR2000pro receivers in-use for on-air operations at the moment they connect the SFX 4104s to the satellite, as that will trigger the download-and-reboot process.

We are confident this software upgrade will address the comments received thus far on the new receivers. However, we again urge anyone who has any problems to contact the Help Desk. We continue to track all issues and inquiries about the new equipment, and your comments about the audio drop-outs and Livewire outputs is what led to this software upgrade.

Stay tuned for more details, which we will share with the system as promptly as possible. And keep sending your comments and questions to the PRSS Help Desk at 800.971.7677 or
