Caution: hot and sharp surfaces ! This professional device needs to be installed by 

qualified personnel only.

 Please check the carton box for any kind of damage on reception of the goods. In case of a 

• 

damaged carton, please contact your dealer before opening the carton.
 !!!!  Danger !!!!  Exposure to extremely high noise levels may cause a permanent hearing 

• 

loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose 

some hearing if exposed to sufficiently intense noise 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.

• 

 Should you ever need to ship the unit, use only the original factory packing.

• 

 Do not spill water or other liquids into or on 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 frayed or broken.

• 

 Always operate the unit with the AC ground wire connected to the electrical system ground.

• 

 Have gain controls on amplifiers turned 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 a battery, mains source, or power supply, regardless of whether the amplifier or console is 

turned on or off.
 Power down & 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 be periodically “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 required to drive equipment to full 

• 

output.

 Do not run the output of any amplifier back into another input.

• 

 Do not ground the red output terminal, never connect a red output terminal to another red 

• 

output terminal.

 In case of mal-function this device should be serviced by qualified service personnel only.
