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 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.

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

Safety Information

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

Verify Line Voltage and Amperage: Your new
MB 500 Bass amplifier has been factory
configured for use with the specific line voltage
for your location:

100-120 Volts/60Hz 15A circuit for USA/Canada.
220-240 Volts/(50-60Hz) 10A circuit for
UK/Australia.
220-240 Volts/(50-60Hz) 10A circuit for Europe.
100-120 Volts/50Hz 15A circuit for Japan.
220-240 Volts/50Hz 10A circuit for Korea.
Proper AC circuit for all other countries.

Safety Information

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 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 sameAC 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.

Please refer to page 10 for more
instructions concerning installation.

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 extention 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 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:

Make sure there is space provided for proper
ventilation. Avoidusing 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.
