MAGN
ET
IC FIELD: !!CAUTION!! Do not locate sensitive high-gain equipment such
as
preamplifiers
or
tape decks
dir
ec
tly above
or
below the unit. Because
this
amplifier has a high power density,
it
has a strong magnetic field, which can induce hum into unshielded devices that are located nearby. The field is
strongest
just
above and below the unit.
If
an equipment rack is used, we recommend locating the amplifier(s) in the bottom
of
the rack and the preamplifier
or
other sensitive equipment
at
the top.
