Safety first!
•  Caution: hot and sharp surfaces! This professional device needs to be installed by qualified
personnel only.
•  Please check the packing for any kind of damage upon reception of the goods. If the packing is
damaged, please contact your dealer before opening it.
•  !!!! Danger!!!! Exposure to high sound pressure levels may cause permanent hearing loss.
Hearing loss induced by exposure to high sound pressure levels will vary from individual to
individual, but nearly everyone will lose some hearing when exposed 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, wear sufficient ear protection while installing
or operating this unit.
• Read all documentation before operating your equipment.
• Keep all documentation for future reference.
• Keep the carton and packing material, even if the equipment has arrived in good condition.
• Should you ever need to send the unit back, use only the original factory packing.
• Do not spill water or other liquids on or into the unit.
• Make sure power outlets conform to the power requirements listed on the back of the unit.
• Do not use the unit if the electrical power cord is damaged.
• Always operate the unit with the AC ground wire connected to the electrical system ground.
•  Turn the level controls on the amplifiers all the way down during power-up to prevent speaker
damage if there are high signal levels at the inputs.
•  Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such
as batteries, mains sources or power supplies, regardless of whether the amplifier or console is
turned ON or OFF.
• Power down and disconnect units from mains voltage before making connections.
• Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
•  Do not operate equipment on a surface or in an environment which may distort the normal flow
of air around the unit. If the unit is used in an extremely dusty or smoky environment, the unit
should regularly be “blown free” of dust.
•  Do not remove the cover. Removing the cover will expose you to potentially dangerous volt-
ages.
•  Do not drive the inputs with a signal level higher than that which is required to drive equipment
to full output.
• Do not run the output of any amplifier back into another input.
• In case of malfunction, this device should be serviced by qualified service personnel only.
