GK Philosophy

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 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 new and old
new solutions. Having taken our own path, GK
products enjoy a unique, unmatched sound,
allowing you every opportunity to make an
original statement.
Having supported my products for over
thirty years, I have learned from the story they tell.
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 talking to us tomorrow.

We’ll be listening,

lems are best solved with

prob

We wish you a lifetime of good playing and
remember to always have fun!

Robert Gallien
Founder and President

Safety Information

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

Verify Line Voltage and Amperage
Your amplifier has been factory configured for

use with the specific line voltage for your location
only. For example, units set to operate
within countries that supply 100-120 volt
electrical service are not compatible with
230-240 volt systems used in other countries.

120 Volt/60Hz 15 amp circuit for the USA and
Canada.
230 Volt/(50/60Hz) 10 amp circuit for the UK and

Safety Information

Australia.
230 Volt/(50/60Hz) 10 amp circuit for Europe.
100 Volt/50Hz 15 amp circuit for Japan.
220 Volt/50Hz 10 amp circuit for Korea.
Proper AC circuit for all other countries.

Connecting the amplifier to a line with
specifications other than indicated above can create
safety and fire hazard, and may damage the
amplifier. If you have any questions about the
voltage requirements for your specific model, or
about the line voltage in your area, contact your
dealer before plugging the unit into a wall outlet.

Verify AC Circuit Capacity Before Use: The high
power output of your amplifier may require heavy
current draw under full-load conditions. To insure
proper performance and avoid potential safety
hazards, we recommend connection to line circuits

pecified “as above”. Connecting to

with ampera
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 Power Cord: To avoid safety hazards, use only
the power cord supplied with your unit. If a
replacement cord is needed, make certain to use a
standard IEC compliant cord. Damaged power
cords should be replaced immediately. When
setting up, make certain that the AC plug is easily
accessible. If you do not intend to use the amplifier for
a considerable length of time, disconnect the plug
from the AC mai
cord.

Earth Grounding 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 adaptor plug with
this product.

Do Not Open the Amplifier Enclosure:
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
the AC power sour
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: Make sure there is space
provided for proper ventilation. 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.
