MB SERIES COMBOS
Quick Start / Tech Talk
Quick Start
The MB Series Combos are designed to be
simple to operate and all controls have a well
defined purpose. These directions will take you
through the basics and give you a good start for
setting up your sound.
Connect your cabinets (MB210 only): In
addition to its internal speakers, the MB210 can
power an external speaker cabinet from the
output marked “Speaker” located on the rear
panel. The external speaker load must be 8 ohm
or above.
Connect your MBP to your MB Combo:
Using a standard XLR microphone cable,
connect the Chain Output located on the rear
panel of your MB Combo (see page 6, rear
panel item #20) to the Chain Input of your MBP
enclosure. If connecting multiple MBP
enclosures, the Chain Output of the MBP is
connected to the additional MBP’s Chain Input.
Initial front panel control settings: MB210,
MB115, MB410 and MB212: Set all EQ and
boost controls to 12 o'clock. The input gain and
master volume should be set to 0 and the
contour and horn buttons in the off (out)
position.
MB112 and MB110: Set all EQ controls to
12:00 and the contour in the out position. The
input gain should be set to zero.
Level and Master Volume settings:
Set the
master volume to 12 o'clock. (MB210, MB115,
MB410 and MB212 only) While playing, turn
the input gain up to the desired volume level.
At this point you can experiment with different
EQ, contour, horn and boost settings.
*Some passive instruments can have output
levels similar to active electronics. If the sound
is distorted the -10db pad should be used.
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, adding to one
another, to create 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 by tuning between two
different shaping circuits, with greatly different
responses. With the control engaged, the low
end is slightly boosted, the mids are dropped
and the high end is pushed up.
G.I.V.E. Technology: The MB210, MB410,
MB115 and MB212 preamps incorporate 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 conjunction with our unique four
band active equalizer and contour, G.I.V.E.
technology produces a consistently pleasing
bass tone.
Smart Protection Circuitry: The MB Series
protection circuitry constantly monitors for
unsafe operating conditions such as short
circuits, miswired 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. 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.
