DANGER: This amplifier can produce lethal levels of
output power! Be very careful when making connections. Do
not attempt to change the output wiring unless AC power has
been removed from the amplifier for at least 10 seconds.
WARNING: This unit is capable of producing very high
sound pressure levels. Continuous exposure to high sound
pressure levels can cause permanent hearing impairment or
loss. Caution is advised and ear protection recommended
when playing at high volumes.
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 equip-
ment 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 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.
