WARNING
TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT EXPOSE THIS
EQUIPMENT TO RAIN OR MOISTURE!
Magnetic Field
CAUTION! Do not locate sensitive high-gain
equipment such as preamplifiers 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 stron-
gest just above and below the unit.
If an equipment rack is used, we recommend locat-
ing the amplifier(s) in the bottom of the rack and the
preamplifier or other sensitive equipment at the top.
IMPORTANT
THE POWER BASE-3 REQUIRES CLASS 1
OUTPUT WIRING. THE POWER BASE-1 AND
