IMPORTANT SAFETY INSTRUCTIONS
Please keep this instruction manual for future reference and for the duration of owning your
GAMMA guitar amplifier. Please carefully read and understand the instructions inside this
owner's manual before attempting to operate your new powered loudspeaker.
This instruction manual includes essential safety information regarding the use and
maintenance of the amplifier. Take special care to heed all warning symbols and signs inside
this manual and those printed on the amplifier on the back of the loudspeaker.
WARNING
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THE AMPLIFIER TO WATER/MOISTURE,
NOR SHOULD YOU OPERATE THE AMPLIFIER NEAR ANY WATER SOURCE.
The exclamation point triangular symbol is intended to alert the user to the presence
of important operating and maintenance(servicing) instructions in the user manual
accompanying the Amplifier.
The lightning flash with an arrow triangular symbol is intended to alert the user to the
presence of non-insulated "dangerous voltage" within the product's enclosure, and may be
of sufficient magnitude to constitute a risk of electric shock.
WARNING
Handle the power supply cord with care.
Do not damage or deform it as it may cause electric shock or malfunction when used. Hold
the plug attachment when removing from wall outlet. Do not pull on the power cord.

G25 & G50 OWNER'S MANUAL
HEARING DAMAGE AND PROLONGED EXPOSURE TO EXCESSIVE SPLs
GAMMA series electric guitar amplifiers are capable of producing extremely loud volume
levels that can cause permanent hearing damage to performers, production crews or the
audience. Hearing protection is recommended during long-term exposure to high SPLs
(sound pressure levels).
Remember, if it hurts, it is definitely too loud! Long term exposure to high SPLs first causes
temporary threshold shifts; limiting your ability to hear the actual loudness and exercise
good judgment. Repeated long term exposure to high SPLs will cause permanent hearing
loss.
Please note the recommended exposure limits in the accompanying table. More information
about these limits is available on the US government Occupational Safety and Health (OSHA)
website at: www.osha.gov.
