The update enables simultaneous recording and transmitting on eligible models. The firmware updates are available to users outside the United States. Eligible models are SM(D)WB/X, SM(D)WB/E01 and SM(D)WB/E06. Together, those verified details define both the change and the group of transmitters to which the update applies.
Simultaneous record and transmit is not available for users in the United States. Users with existing units in Canada must send their units to the Lectrosonics factory for the upgrade. Those geographic requirements are part of the update conditions, so model eligibility and location both matter before an upgrade is attempted.
Firmware downloads are ZIP files that are extracted and copied to an SD card for installation. Lectrosonics warns that bypassing update steps or loading incorrect firmware may cause a unit not to function properly. The installation guidance therefore belongs with the feature announcement rather than being treated as a separate maintenance detail.
