MB SERIES

Quick Start

The MB Series 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 5 for details). 

2. Connect your cabinets:

Connect  your  speaker  cabinets  to  the  amplifier 

outputs  marked  Speaker.  The  MB  features  dual 

use  speaker  connections.  These  unique  jacks 

allow for Speakon or 1/4” plugs to be used. 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 input volume controls at 0. 

4. Plug in your bass:

Using  an  instrument  (shielded)  cable,  connect 

your bass to the Input jack 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 conventional,  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.  Turn  the 

Input Volume knob up as you play to the desired 

output level. If the clip light (pad button) flashes 

more  than  occasionally,  press  the  -10db  pad 

button in and turn the Input Volume knob up. If it 

is still lighting often, try turning the volume down 

on your bass.
