Quick Start - Gallien-Krueger MB115 Owner's Manual

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.
1. Plug it in:
Set the power switch to the off (out) position
and connect the supplied power cord from the
amplifier AC receptacle to an AC power outlet
of proper voltage and power rating (see safety
information on page 4 for details).
2. 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.
3. Initial front panel control settings:
MB210, MB115 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) posi-
tion.
MB112: Set all EQ controls to 12:00 and
the contour in the out position. The input gain
should be set to zero.
4. Plug in your bass:
Using an instrument (shielded) cable, connect
your bass to the input jack that corresponds to
your instrument's output (active or passive) and
press the power switch on. If you have active
tone controls on your bass, turn all of the
controls to the middle or flat position and turn
the volume all the way up. If you have conven-
tional, passive tone controls, turn all tone and
volume controls all the way up.

5. Level and Master Volume settings:
Set the master volume to 3 o'clock. (MB210,
MB115 and MB212 only) While playing, turn
the input gain up to the desired volume level.
*Some passive instruments can have output
levels similar to active electronics. If the sound
is distorted when using the passive input, the
active input should be used.
* It is recommended that the limiter be engaged
during high volume applications.
At this point you can experiment with different
EQ, contour, horn and boost settings.
