I just realized I typed the question incorrectly, the specs for SST3 show >60V/µS, while for SST2 show >160V/µs. Maybe digit "1" was lost when manual was composed for SST3?
For all of our common ground amplifiers, including the 4B, 3B, and 2B, the slew rate is 60 V/ms. For all bridged mode amplifiers, including the 7B, 14B, and 28B, the slew rate is double, at 120 V/ms. This applies to all SST/SST2/Cubed models.
Unfortunately, some owner's manuals made it to print with errors in the slew rate specifications...
Thanks,
Mike
