How does one detect ultrasonic oscillations?
** The first sign will usually be that VU meters on the amplifier or desk become hard pegged when there is no loud sound.
A few seconds later, smoke will appear from the amp/amp rack.
Large cone speakers are normally immune from damage ( VC inductance saves them) while small horn driers including piezos are vulnerable and will also smoke.
