[QUOTE="John Roberts, post: 57925, member: 126"] Re: Intermod distortion 2-way vs 3-way In an amusing related story I recall an early Crown class D amp that would literally shut off it's output stage, if there was no audio input. The sensing circuit was so sensitive it could be fooled into thinking there was signal if a loud noise in the room generated a voltage from the speaker. This was rather unexpected as speakers are generally terminated with a very low impedance from conventional amps. I suspect this was a quirk of how the Crown amp was configured at idle that left the speaker floating or terminated with a high impedance. :-) JR [/QUOTE]
