CAUTION! Do not locate sensitive high-gain equipment
such as amplifiers or tape decks directly 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 amplifier
or other sensitive equipment at the top.
