Peavey PCX-V12 - Manual (Page 12)

5. Caution
1. Since the installation of the antenna
influences the operating efficiency of
the receiver, the most important rule is
to minimize the distance as much as
possible between the receiving antenna
and the microphone for the best
reception and performance.
2. The output voltage of the external DC
power supply should not be below 12V,
otherwise it will not work properly. If the
voltage is over 15V some components
of the receiver will be damaged due to
excessive current draw. Use a power
supply with a 1A minimum rating.
