Software & Firmware Archives

Improvements

• Fixed distorted audio issue on ULXD4 devices with Dante version REV3
• Fixed issue where ULXD4 devices sometimes disappear from Wireless Workbench® and do not reconnect

Important

• ULX-D 2.X firmware versions are incompatible with ULX-D or QLX-D 1.X firmware versions. To ensure all receivers and transmitters in a configuration function with each other, update all devices to the same firmware version.

Known Issues

• Group Scan Deployment and Custom Group Load may not work with other ULXD4/ULXD4D/ ULXD4Q that are running older firmware versions

Notes

• User Guide
