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

old problems are best solved with new

and
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,

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

Robert Gallien
Founder and President

This amplifier is capable of producing high sound

pressure levels. Continued exposure to high SPL’s can

cause damage to your hearing. Always set the volume at

a safe listening level or use hearing protection if the unit

is operated at higher levels.

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.

100-120 Volt/60Hz 15A circuit for USA and
Canada.
220-240 Volt/(50/60Hz) 10A circuit for UK and

Safety Information

Australia.
220-240 Volt/(50/60Hz) 10 A circuit for Europe.
100-120 Volt/50Hz 15A circuit for Japan.
220-240 Volt/50Hz 10A 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 plugg

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
with amperage specified “as above”. 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.

ing the unit into a wall outlet.

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 Mains Socket. Do not use an extension
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 adapter 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
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: 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.
