Safety Instructions

• 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.

• 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 voltages.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.

• In case of mal-function this device should be serviced by

qualiﬁed service personnel only.
