of both sides of the conversation.

can connect the ComPack Male XLR to your single channel belt-
pack intercom system.
?
Can I connect ComPack to a powered beltpack line?
!
Yes, the ComPack has a DC blocking cap so it will not be dam-
aged if connected to a powered line, although DC power is not
necessary for operation.
?
I've lost the power supply for my ComPack. I have another
power supply that fits from a different product. Can I use
this instead?
!
NO! Never use a power supply other than the one that was sup-
plied by your manufacturer. Power supplies are available in ei-
ther AC or DC output with many combinations of voltage and
current. DC supplies carry either positive or negative center pin
output and may or may not be regulated. If you connect a nega-
tive center pin power supply to a positive center pin jack, it's just
like hooking up the battery cables to your car backwards. Obvi-
ously you would not want to do this to your expensive audio
equipment. Regulation is the tolerance to the specified voltage
of your DC power supply. All of our power supplies have low
noise 5% tolerance. So our 9V DC power supplies will always
output 9 volts +/- 5%, whether you are using no power at all or
applying a full load. Most consumer power supplies are not
regulated. A non-regulated 9V, 800mA power supply could actu-
ally output 16V until an 800 mA load is applied. This could dam-
age your equipment and create a great deal of noise. Also, be-
cause there is no standard for the size of your power jack, a
16VAC and a 1.5VDC power supply could both have the same
2.1mm jack.
