Cautions and Warnings
Exclamation Mark Symbol:
This symbol is used to alert the user to
make special note of important
operating or maintenance instructions.
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: Do not expose this unit to rain or moisture.
WARNING: Only properly trained and qualified technicians should attempt to
service this unit. There are no user serviceable parts inside.
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.
CAUTION: When performing tests, do not connect any load to the amplifier until
instructed to do so. There is no danger to the amplifier in operating without any
load (open outputs).
WARNING: Do not change the position of the mode switches when the amplifier is
turned on. If the position of these switches is changed while the amplifier is
powered, transients may damage your speakers.
WARNING: Heatsinks are not at ground potential. Simultaneously touching either
heatsink and ground, or both heatsinks will cause electrical shock.
CAUTION: Eye protection should be worn at all times when protective covers are
removed and the amplifier is plugged in.
CAUTION: When performing tests that require a load, the load must be resistive
and must be capable of handling 1000 W (per channel).
CAUTION: Disconnect the power cord before installing or removing any cover or
panel.
CAUTION: Electrostatic discharge will destroy certain components in the amplifier.
Techicians must have approved ESD protection. Proper grounding straps and test
equipment are required.

to the presence of dangerous
voltages and the possible risk of
electric shock.
