I just hope Dan wont mind me sharing this email of his...besides its for all FloridaMagic Sound System owners
Hi Wanlu,
Thanks for your email. I'll be happy to address your concerns:
1. I'm not sure which battery charger you have, but if it was purchased
from us in the last couple of years, it is`a 110V charger and a voltage
converter should be used for 220V (earlier models had a 110/220 switch
on the bottom and were large units (almost as big as the battery!) and
could charge at several different voltages. If you have this model,
simply switch to 220, if not this model, use a voltage converter)
2. The battery does not have a memory and does not need to be drained.
It uses the same principle as your car battery and can be recharged at
any time. If you have a show on Saturday, put it on the charger for a
couple of hours on Friday and you are topped up, good to go.
3. The unit has a high quality wireless mic system built in, so if you
are getting feedback, it is caused by one of these three things:
1. Do not stand in front of the speaker. Never set the unit up behind
you. Personally, I position my system approximately 10 feet away from
me, to my left (although it could be to the right if that suits you..)
and slightly in front of me.
2. Turning the volume up too loud for the size room. If you are in a
small room and crank up the volume, the sound will bounce off the back
wall and come back to the system causing feedback. Because the unit is
so small, many people feel that you have to crank up the volume - not
true with this system - its very powerful!
3. A weak 9V battery in the beltpack. Replace with a brand new alkaline
battery for every 2-3 hours of talk time (every 2 shows..)
So, if you are getting feedback, just ask yourself, "where am I
standing?", "How high is the volume?", "When was the last time I changed
the battery?". The Shure mic is a less efficient mic which uses much
more of the units power, thus giving you less feedback, but not as much
volume. If the Shure mic works with the pas767 transmitter, and you
prefer it, then feel free to use the Shure mic. You certainly won't hurt
anything, although you probably won't get as much volume from the system.
Best Regards,

My problem now is that the charger does not charge the battery because the previous owner said he used the charger using 220v despite the fact that it says 110v...what a dumb dumb

He is even insisting that when he used it on 220v, there was no problem

anyway, Im having the charger checked tomorow, hoping it can be fixed or maybe I can just get a new charger from Dan...
Thanks everyone.
