permanent hearing loss. Individuals vary considerably to sound
pressure level induced hearing loss but nearly everyone will
lose some hearing if exposed to high sound pressure levels for
a sufficient amount of time. Therefore it is recommended that
all persons exposed to equipment capable of producing high
sound pressure levels, such as this amplifier, be protected by
hearing protection while installing or operating this unit.

• Read all documentation before operating your equipment.

• Keep all documentation for future reference.

• Save the carton and packing material even if the equipment has
arrived in good condition.

the inputs.

• Do not connect the inputs / outputs of amplifiers or consoles
to any other voltage source, such as a battery, mains source, or
power supply, regardless of whether the amplifier or console is
turned on or off.
