Characteristics of the MB Fusion: The MB
Fusion is a flexible, state of the art amplifier
designed to deliver maximum performance while
remaining small, lightweight and
operate. This is accomplished through a few, very
important features:
∙ Six stage tube preamp
·Class D power supply and power amp.
·Four,
Bass
specific
equalization for precise tone control.
·Balanced direct output eliminates the need for
a direct box.
·Continuously variable fan cooling.
Equalization: Standard tone controls and graphic
equalizers give you plenty of variation, but they
don't provide what the instrument really needs.
The fact is, graphic equalizers are intended for
room
equalization.
Gallien-Krueger amplifiers reflects 40 years of
continuous development and refinement.
The GK equalizer is unique to the industry, it's not
just a normal four band equalizer, each section is a
special circuit optimized to perform a bass
specific job in its range of operation.
These sections are wired in series, so they add to
one another creating a tremendously flexible
equalizer, that sounds natural at any setting. Now
it is possible to obtain the sound you desire.
Contour: The Contour control is used to
completely revoice the amplifier. The Contour
control tunes between two different shaping
circuits, with greatly different responses. With the
control all the way up, the low end is slightly
boosted, the mids are dropped and the high end is
pushed up. This feature is only found in GK
amplifiers.

in
G.I.V.E. Technology: As in all GK pre-amps, the
MB Fusion pre-amp incorporates what we call
G.I.V.E (Gate Induced Valve Effect) technology.
We use field effect devices with the gate biased in
a way that emphasizes the optimum harmonic
content of the signal. Working in concert with our
unique four band active equalizer, and three stage
voicing
filter
section,
produces a consistently pleasing bass tone.
Cool Running = Reliability: To cool the amp
when its being driven hard, we've designed a
temperature sensitive fan cooling system. When
the amp is under a light load, the fan is off or
running at a low speed, reducing fan noise. As the
amp works harder, the fan speed increases to keep
everything cool.
Smart Protection Circuitry: The MB Fusion
protection circuitry constantly monitors for unsafe
operating conditions such as short circuits, poorly
wired speaker cables, blown speakers, improper
ventilation, and incorrect speaker configurations.
In addition, protection is provided during power
up/down. If the MB Fusion senses any unsafe
operating conditions, the output signal is
immediately muted and the power light changes
from blue to red. The amplifier will remain muted
until the fault is removed. If the protection circuit
activates while playing, turn the amplifier off and
check the amplifier speaker output connections.
Be sure that you are not exceeding the maximum
recommend load described in this manual. If the
problem persists, contact GK directly for technical
advice.
In Closing, you should now have a thorough
understanding of how your new MB Fusion
amplifier works and what advantages it can offer
you in getting "your" sound. We thank you for
reading the Owner's Manual and wish you the
best of times! Please send us your comments via
