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

2 REQUIRE CLASS 2 OUTPUT WIRING.
