Below are links to the current firmware versions for the LT and LT/E01 transmitters.
These are zip files. After downloading extract the file into a temporary folder. Use the USB Firmware Updater program to update firmware.
Before beginning, verify which model of transmitter you have:
LT Product Label
LT/E01 Product Label
Special note regarding LT and LT/E01 firmware:
The LT and LT/E01 models require different firmware loads. The LT is sold in the US and Canada; the LT/E01 is sold in the European Union. Be sure to download the correct update file and double-check before installing!
Please note that there are two versions of LT/E01 firmware. Units with version 1.xx firmware currently installed can only be upgraded to the latest v1.xx firmware; units with version 2.xx firmware installed can only be upgraded to the latest v2.xx firmware.
Please note: version 6.x firmware for the LT is for use only in new product shipped after October 13, 2018 to US customers. These will bear the following new FCC ID numbers:
- DBZLTA1A
- DBZLTB1A
These ID numbers indicate conformance to the ETSI standard now in effect for wireless microphone transmitters in the United States and Canada. Here the “Nu Hybrid” compatibility mode replaces the old “Hybrid” mode used in previous 1.x and 2.x versions of the product.
Are you looking for firmware updates for older LT transmitters with version 1.x series firmware?
For older LT transmitters which originally shipped with v1.x firmware, series 7.x firmware is available in which the “Nu Hybrid” compatability mode replaces the old “Hybrid” mode used in previous versions of the product. “Nu Hybrid” mode conforms to the ETSI RF emission standard now in effect for wireless microphone transmitters in the US and Canada.
Version 7.x firmware is not compatible with newer transmitters with version 6.x firmware. Do not install version 7.x firmware in transmitters with version 6.x firmware! In this case the higher version number (7 vs 6) does not imply upward compatibility or additional features.
Are you looking for firmware updates for LT transmitters with version 2.x series firmware? If so, version 6.x firmware can be installed.
Note: in version 6.x, “NU Hybrid” replaces the “Hybrid” mode from the earlier version. “Nu Hybrid” mode conforms to the ETSI RF emission standard now in effect for wireless microphone transmitters in the US and Canada.
