I have a Mackie mixer on top of my M400. Could there be any possible
magnetic damage?

Greetings All, 


The MK-I/II speaker magnets are low enough and  distant 
enough not to cause any gradual degredation of tapes. 
During normal operation ..... If a tape breaks,it will brush past 
the magnet and partially erase the tape. LH Tapes 1-4 from 
Gordon's ex-MK-I had noticeable drop-outs of audio. 
Someone/something wasn't careful..... 


The inverse squares law of physics applies to light , electricity, 
and magnetism.   Ken M. was taking the proper precautions 
during MK-II tape change.  I probably would have unbolted the 
Wharfedales to make 100 % sure. 


BTW, the JKMK6 has magnets even closer to the bottoms of 
the M400 tape-frames within. No problems seen in two years +. 
I installed mu-metal (mag. shield) adjacent to the spkrs. 
to preclude a future disaster. My pro-active policy of safety. 


That's why we 'Tron users cannot stress enough the need to 
keep headblocks demagged,non-magnetized hand-tools, 
electrical precautions when installing headblock cable, 
yada,yada, yada..... 


Cheers,  Jerry K.
