Hilmar-at-Bose posted a great message about phantom power (and why the Bose system is 24 volts)<ref>Hilmar talks about phantom power voltage [http://bose.infopop.cc/eve/forums?a=tpc&s=8206048934&f=3976055944&m=2141012531&r=3311013631#3311013631 24 vs 48 volts]</ref>.
{{:Classic/Model I/Phantom Power}}
 
Let me add some technical ramblings to the 48/24 discussion. Condenser microphones require phantom for a couple of reasons
 
a) power an internal pre-amp
b) supply polarization voltage to the capsule
c) run an internal DC-DC converter that in turn fuels either preamp, capsule or both
 
Most condenser mics fall in category a). In this case, reducing the phantom from 48V to 24V has virtually no effect. In theory you can get higher voltages out of a 48V supply, but at this point you would clip the input of you mic preamp anyway.
 
In category b), the effect of dropping the phantom is that the overall sensitivity of the mic goes down by 6 dB. On the other hand, the max SPL goes up by 6dB. In general, you will simply have to turn up the trim a little more, but there shouldn't be any other effects.
 
Case c) is basically hit or miss. Either it works just fine or it doesn't work at all. I don't think there is any in-between.
 
Again, most mics these days fall in category a) and that's one of the reason why the the International Engineering Consortium (IEC) in it's standard 61938 (1996) in section 7.4.5. explicitly recommends
 
:quote: Although 12V and 48V systems are still in use, 24V systems are preferred for new developments
 
and that's why we've chosen 24V.[/i]

If possible you should avoid exposing the PS1 (or any kind of electronics for that matter) to direct blazing sunlight. That can generate enormous amounts of heat inside the system to the point where it actually has to shut down (to protect some of the internal components). As a general rule, if it's too hot for you as the performer, than it's probably also too hot for the system. Finding a little shade will certainly help in a scenario like this.

The best way to deal with a beverage accident is to
# Please, shut the system of immediately (liquid in the PS1 is a potential safety hazard)
# If you have the opportunity pour clear water after the beverage (to rinse out sticky stuff)
# wiggle a little to make sure all the water comes out of the drain holes in the bottom.
# Let the system dry out thoroughly for at least one day, several days are better
