MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain
equip ment such as preamplifi ers or tape decks
directly above or below the unit. Because this
amplifi er has a high power density, it has a strong
magnetic fi eld which can induce hum into
unshielded devices that are located nearby. The fi eld
is strongest just above and below the unit.
If an equipment rack is used, we recommend
locat ing the amplifi er(s) in the bottom of the rack
and the preamplifi er or other sensitive equipment at
the top.
