PowerMatch amplifiers are not saving front-panel setting changes. Settings revert back on power cycles even when (on network version amps) users elect to “Restore Last Settings” in ControlSpace Designer.
A firmware bug prevents front-panel changes from being persistent through power cycles of the amplifier.
PowerMatch all amplifiers, all voltages, running firmware version 1.350 (packaged with CSD 3.2) and later.
Use ControlSpace Designer software and a connection to the amplifier to upload and save settings to the amplifier. Until the issue is fixed, we recommend not making front panel parameter changes that are intended to remain.
Root cause found and fixed in a new version of firmware (to be rolled out shortly).
