After many many "False Starts" and "Major Setbacks" I am currently slowly "Inching" ever closer to losing my "Lathe Cutting Virginity" and could do with a little advice

Even though I had inserted 2x 200mA Inline Fuses into the Loudspeaker Lines I somehow contrived to Completely destroy the first pair of Loudspeakers

The Smoke damage to the Room will be soon be sorted out with a little call, in the very near future to my Painting and Decorating Contractor

I am somewhat puzzled why the Fuses did nothing to Protect the Loudspeakers, they were purchased Many Moons Ago, I don't remember if they were Slow Blow or not, possibly I have Mis-labelled them when moving home and they are a Higher Rating, but hey, better a Basic Loudspeaker Burn-Out, than a Priceless Cutterhead eh??

Now, having cleaned up most of the mess and damage to the room, I am in the process of having another attempt to dial things in. I no-longer "Trust" the LED Displays on either the FBQ6200 or the VU Meter and as an extra precaution, have taken the FBQ1000 and the MDX1600 out of the Audio chain, and have ((For Now) inserted a 50K Linear Stereo Pot into the Audio Lines in a "Belt and Braces" attempt to further attenuate the Signal to the Amplifier and avoid a repetition of this Faux Par.
The Amp is this one :- https://www.hifi-tower.co.uk/Sound-Light/PA-Systems-Audio/PA-Amplifiers/SPL700-Watt-DJ-PA-Amplifier-EQ-Hi-Fi-Audio-Amp-Black-Equalizer-2x-350-W-4-Ohm-2x-250-W-8-Ohm.html
When I bought this it was around twice the price, but was just about all I could afford, the Specifications seemed to fit the bill for what I was trying to acheive, I am not a Mastering Studio where the "Big Bucks" usually buys the "Best Gear" I'm just a "Hobbyist" after all!!!
Now Trolls, I have finally, afer hours of searching, located the errant literature relating to the FBQ6200 Equaliser et al. While I continue endeavours to fulfill my long held ambitions to Cut my Very Own Records, I am hoping someone can help me out here??
Firstly, apologies if this has been asked a million times before, but my questions are these :-
Q1) Without opening it up, I am assuming that the "Volume Controls" on the SPL700 Amplifier simply attenuate the incoming Audio Signal, is this Correct??
Q2) Do Most Lathetrolls? All Lathetrolls? Any Lathetrolls? No Lathetrolls? Set the Audio Signal Levels "Back in the Audio Chain" and leave the Amplifier "Volume Controls" Cranked Up?? I don't know if this is correct, but I am assuming this is how the Amplifiers have the "Headroom" to deliver the short duration peaks??
Q3, Having somewhat lost my faith in Rupturable Fuses, has any Lathetroll devised a ((VERY)) "Simple to Make" Adjustable Overload Cut-Out Circuit, that does not need Computer programming Skills using something like the Current Sensor ACS712 Module?? 185mV per Amp output must surely be plenty to drive some form of Small Boost Amplifier in order to trip/drive a protection relay??
Q4) If relying solely on Fuses for Cutterhead Protection, would "Quick Blow" be the most prudent approach??
Looking Forward to a little guidance here,
Many thanks Best Regards Soulbear
