How did they get a clean recording if the speaker went ?
Its a 3 x 12 w/ one mic on it -how do you isolate a blown speaker from the recording ?
If it didnt make a noise when it blew how did they know it was blown ?
If you notice before Parish comes out to swap the speaker, he first is seen leaning over the back to the front of it. He can be seen sometimes feeling the speaker to find the one not moving. Sometimes Jerry points out the problem. In this case they figured out that it was the middle speaker pretty quick because the mic is on it and someone else comes out and moves the mic to the top speaker. What I am only guessing is that Healy radio'd in that he was losing Jerry at the board and needed to push him for that solo, so the mic was picking up the other 2 speakers pretty good. The crew went into action mid song and got it taken care of. The McIntosh amps have an Autoformer which allows them to run at their rated output with any of their impedance taps. So even though he lost a speaker, his volume never really missed a beat. The impedance mismatch will cause it to run a little hotter and may allow it to get a little hairier faster if really severe, but overall it will run just fine. Each of his speakers are wired separately to their own jacks in the back of the mac. These jacks are wired in parallel so the speakers can be swapped without removing any other speaker. The whole rig stays up and running just fine, except for this instance where the front of the house mixers signal was degraded because the speaker they mic'd blew.
