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 am a
Stanford educated engineer who worked his 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

Introduction

reflect my attitudes and life experiences. I don’t model
my designs after other manufacturer’s products (as
some of our competitors are proud of reciting).
Instead, I believe new and old problems are best solved
with new solutions. Having taken our own path,
products enjoy a unique, unmatched sound, allowing
the artist using them every opportunity to make an
original statement.
Having supported my products for over thirty years, I
have learned from the story they tell.
is a reflection of that story, and has a commitment to
support that legacy. Just as the products I created
thirty years ago are still telling their story, the products
we create today will be talking to us tomorrow.

Safety Information

400RB-IV Series

Verify Line, Voltage and Amperage Before
Use:

Your new 400RB-IV Series Bass Amp has been factory
configured for use with:

.

· 120 Volt/60Hz 20 Amp circuit for USA & Canada.

.

· 230 Volt/50Hz 10 Amp circuit for Europe
& Australia.

.

· 100 Volt/50Hz 20 Amp circuit for Japan.

.

· Proper AC circuit for all other countries.

Connecting the amplifier to a line with specifications
other than indicated above can create a 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 multiple
amplifiers to the same circuit, or connecting the ampli­fier 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 to possibility of power variation and
electrical start-up noise affecting your sound.

Do Not Use Extension Cords:

To avoid safety hazards, use only the power cord supplied
with your unit. If a replacement cord is used, make
certain that it is of consistent quality and gauge as the
original. We do not recommend using extension cords
with this product. As with all electrical devices, do not
run power cords under rugs or carpets or place heavy
objects on them. Damaged power cords should be
replaced immediately with cords meeting factory specifi­cations.

Handle The AC Power Cord Gently:

When disconnecting the power cord from an AC outlet,
always pull the plug, never pull the cord. If you do not
intend to use the amplifier for a considerable length of
time, disconnect the plug from the AC outlet.

Mains Disconnect:

If the AC mains has to be completely disconnected, the
plug/power cord is used as the mains disconnect
device and shall remain readily operable.

Do Not Open The Amplifier Enclosure:

There are no user-serviceable components inside this
product. Opening the amplifier enclosure may present a
shock hazard, and modification to the product will void
your warranty. If liquid enters the unit, or any metal
object such as a paper clip, wire, or staple accidentally
falls inside the enclosure, disconnect the unit from the
AC power source immediately and consult an authorized
service station.

Safety Information

Warning: Do not disconnect or plug in the instru­ment/speaker cable with the amplifier power on.
Be sure the amplifier unit is turned off before
connecting to the speaker.

Unpacking:

The carton and packing materials used in shipping your
new amplifier were specially designed to cushion it from
the shocks and vibration that occur during transport. We
suggest that you save the carton and packing materials
for use in shipping, in the event you move, or the
amplifier needs repair.
