If your amplifier has a microprocessor, it shouldn't be too tough to sense
the input frequency and cause the amp to shut down within the specified
limits. And since it would be in firmware, it would be tough for a non-techie
to circumvent. If I'm not mistaken, several of the "big boys" have been using
microprocessors and/or DSP for a while.
