Quick Start

The MB 800 amplifier is designed to be simple to

operate. 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 Off 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: Connect your speaker

cabinets to the amplifier outputs marked

SPEAKER using a standard two conductor

speakon cable or Gallien-Krueger four conductor

speaker cable. Be sure not to exceed the

recommended speaker load as noted below.

Maximum Recommended Speaker Loads:

One 4 Ohm, or two 8 Ohm cabinets.

3. Initial front panel control settings: Set all

EQ controls and contour knob to 12 o'clock. Set

the Gain A, Gain B, Level B and Master control

to the full counterclockwise position. Upon

power up, the Gain A control is the default input

gain adjustment and should be lit blue. If the

Gain A knob is not lit, push it until a slight click

is felt and the knob indicator is lit blue.

4. Plug in your bass: Using an instrument

(shielded) cable, connect your bass to the Input

jack and press the power switch to the on (in)

position. 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 conventional, passive tone controls,

turn all tone and volume controls all the way up.

5. Level and Master Volume settings: Set the

Master control to 12 o'clock. Turn the Gain A

knob up as you play until the desired output

volume is reached. If the input clip indicator (the

ring surrounding the -10 pad switch) flashes

more than occasionally or distortion is audible,

set the -10dB pad switch to the up position and

increase the Gain A level until the desired output

volume is reached. If the clip indicator continues

to light often, it may be necessary to decrease the

volume on your instrument.

*For high volume applications, it may be

necessary to increase the Master control beyond

MB 800

the 12 o'clock setting.

6. Gain B/Level B: Pushing the Gain B knob

(also selectable from the provided footswitch)

activates the Gain B input and Level B controls.

Once activated (indicated by the Gain B and

Level B knob lit blue), bring the Level B control

to the 12 o'clock position and increase the Gain B

level until the desired volume is heard. Higher

Gain

settings

overdriven/distorted tones while lower settings

will maintain a clearer, less overdriven tone.

When used in conjunction with the Level B

control, the desired overdrive and output volume

can be set relative to the Gain A level. You should

be hearing your bass quite well through both the

Gain A and Gain B channels. At this point you

can experiment with different EQ and Contour

settings. A sample setting can also be found on

page 7.

*The Limiter is active upon power up (Master is

lit blue) and is recommended for high volume

applications.
