Blectrical
Wiring
To take
full
advantage of the excellent rignul
to noise
ratio of the
Axion, it is necessary to read this
part
of
the rnanual carefully.
Hurn,
radio
frequency interferance,buzzes
and instability
are
often
carsed
by
irnproper
widng
and poor
grounding.
Sornetirnes
the in-
corning
electrical
ground
is inadequate and a
dedicated
grourrd
would
need
to
be instslled for the audio equiprnent.
