Firmware Updating Procedure

The XD-V75 receiver features a USB port, which may be used for updating the firmware of both the receiver and transmitter when new versions are released. This procedure is detailed on the Line 6 website (www.line6.com).

The XD-V75 receiver can be used to update the XD-V70 generation of transmitters to enhance their feature set and compatibility with the XD-V75 receiver, and can also update the CPU in the XD- V70 receiver (as well as the XD-V30, Relay™ G30, Relay™ G50, and Relay™ G90 receiver and transmitters). When using both XD-V70 and XD-V75 units in the same installation, it is recommended to upgrade the older units to the latest firmware. Details are also on the web site.
