P.A. speakers and pacemakers

Hello all, I have had a pacemaker ( due to bradycardia ) for a year or so.

I set up and use a P.A. system and radio microphone 3 or 4 days a week , sometimes more,  which involves lifting and moving speakers.  Should I be careful of  proximity when they are in use ?  They are typically 500 - 1000 watts in power, although not usually run at maximum volume.   

Thanks ,    Fozzy65

The concern is the strength of the magnet in the speakers, not the wattage. So it depends.

About 5  years ago I was standing under speakers at a funeral service.  I started to feel very 'odd'  I moved away and sat down.  After about 15 mins I was fine.  I did not know at the time that speakers had magnets, but all was well when I moved.  I was really close to them.

I know that P.A. speakers  contain a magnet , bigger speaker - bigger magnet , and once you connect them to an amplifier the voice coil in the speaker then becomes an electromagnet also, which must enlarge the magnetic field as you apply more power.

A microphone is basically a speaker in reverse, but with far less magnetic field. 

As my other half has covered the fridge with fridge magnets, collected from islands and countries we have visited,  would it be safe to tell her that I must not go near the fridge...and she will have to do all food prep and cooking, and fetch my beers also ?  Ha ha.

Also , I did'nt know that PMs can make warning noises !
