Always Listening

I have never seen the point in doing things the way others have done them. I also have not been very interested in following the latest fad. I’m a Stanford educated engineer who worked my way through school as a musician. Like all musicians, I have lugged amplifiers up stairways and into car trunks, always wondering why these things had to be so heavy, bulky, and hard to handle.

As I am the principal innovator at GK, our products reflect my attitudes and life experiences. I don’t model my designs after other manufacturers’ products. Instead, I believe these problems are best solved with new solutions. Having taken our own path, GK products enjoy a unique, unmatched sound, allowing you every opportunity to make an original statement with your music.

Having supported my products for over thirty years, I havelearnedfromthestorytheytell. Gallien-Krueger is a reflection of that story, and has a commitment to support that legacy. Just as the products I created over thirty five years ago are still telling their story, the products we create today will be spreading the word for years to come.

We’ll be listening,

Robert Gallien

Safety Information

Please read all enclosed safety precautions before connecting or operating this product.

Verify Line Voltage and Amperage: Your new amplifier has been factory configured for use with the following:

120 Volt/60Hz 15 A circuit for USA/Canada.

240 Volt/50Hz 10 A circuit for UK/Australia.

230 Volt/50Hz 10 A circuit for Europe.

100 Volt/50Hz 15 A circuit for Japan.

220 Volt/50Hz 10 A circuit for Korea.

VerifyAC Circuit Capacity Before Use: The high power output of your amplifier may require heavy current draw under full-load conditions. Connecting the amplifier to a line with specifications other than indicated above can create a safety or fire hazard and may damage the amplifier. Connecting to the same circuit used by other heavy-power devices, such as high-wattage lights, may cause circuit breakers to trip. It is always a good idea to avoid using any audio equipment on the same AC circuit as equipment with motors, such as air conditioners or refrigerators. This will lessen the possibility of power variation and electrical start-up noise affecting your sound.

AC PowerCord: To avoid safety hazards, use only thepowercordsuppliedwithyourunit. Ifareplacement cord is needed, make certain to use a standard IEC compliant cord. Damaged power cords should be replaced immediately. When setting up, makecertain thattheACplugiseasilyaccessible. Ifyoudonotintend to use the amplifier for a considerable length of time, disconnect the plug from the AC Mains Socket.

Earth Ground Connection: To prevent electric shock, do not remove the grounding plug on the power cord, or use any plug or extension cord that does not have a grounding plug provided. Make certain that the AC outlet is properly grounded as well. Do not use an adapter plug with this product.

Do Not Open theAmplifier Enclosure: There are no user-serviceable parts inside this product. Opening the amplifier enclosure may present a shock hazard. Modification to the product will void your warranty. If liquid enters the unit, or any metal object such as a paper clip accidentally falls inside the enclosure, disconnect the unit from theAC power source immediately and consult an authorized service station.

Setup: To insure proper operation and to avoid potential safety hazards, place the unit on a firm, level surface. Do not plug or unplug the instrument or speaker cable while the amplifier power is on.

Heat & Ventilation: Air flows from back to front of the unit , make sure there is at least 8 inches of clearance on top, sides and back of the amplifier, in the event that the unit is rack mounted, maintain an 8” clearance on the back and front of the unit, 1.75” or one rack space on top and bottom. Avoid using in extremely hot or cold locations and areas that are exposed to direct sunlight or near heating equipment. Avoid using in moist or high humidity areas.

Cleaning&Maintenance: Cleanonlywith drycloth. Never use benzene, thinner, alcohol, or other volatile cleaning agents. Do not use abrasive cleaners, as they maydamagethefinishofmetalparts. Avoidspraying insecticides near the unit. No other maintenance should be necessary.

Traveling: If Traveling with the unit frequently, we recommend a road case or cover to protect it from scratches and road wear.
