Tech Talk

Characteristics of the MB Series:
The MB Series is a flexible, state-of-the-art
amplifier designed
performance while remaining small, lightweight
and simple to operate. This is accomplished
through a few, very important features:
·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. The equalization in 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 is used to completely revoice the amplifier.
This 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 is only found
in GK amplifiers.

bands of active
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 Series protection circuitry constantly monitors for
unsafe operating conditions such as short circuits,
miss-wired speaker cables, blown speakers, improper
ventilation, and incorrect speaker configurations. In
addition, protection is provided during power up/down. If
the MB Series 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 Series 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
