DANGER: The outputs of the amplifier can produce LETHAL energy levels! Be
very careful when making connections. Do not attempt to change output wiring
until the amplifier has been off at least 10 seconds.

WARNING: This unit is capable of producing high sound pressure levels.
Continued exposure to high sound pressure levels can cause permanent hearing
impairment or loss. User caution is advised and ear protection is recommended
when using at high levels.

WARNING: When performing service checks with the power off, discharge the
main power supplies fully before taking any measurements or touching any
electrical components. A 300-ohm 10-W resistor is recommended for this. Hold the
resistor with pliers, as the resistor may become extremely hot.

CAUTION: Under load, with a sine wave signal at full power into both channels,
the amplifier may draw in excess of 30 amperes from the AC service mains.
