:

1)  Connect your instrument to input A. 
2)  Connect the Output to power amplifier or amplifier head. 
3)  Set the A/B switch so that Channel A is active. 
4)  Set the BASS and TREBLE controls to 12 o’clock and 

the BOOST to minimum position. 

5)  Set the DRIVE control to minimum position and the 

MIDDLE and EDGE to 12 o’clock. 

6)  Make sure all switches are in the outer position. 
7)  Connect to mixer from the Balanced XLR Output if 

required. 

    You can now dial in two different sound on the A and B 
channels respectively. By engaging the A+B mode switch you 
may now dial in your basic sound on channel A, and when 
selecting B you will add the B to the A channel. This is useful 
for overdriven sounds and lead playing. Both LED’s will now 
light. 

BALANCED OUTPUT

 - Is a high quality balanced output. The 

balanced output functions as an interface for connecting to PA mixing 
consoles or to studio or broadcast recording units. 
    Lifting ground is a great aid in many occasions. When required, set the 
Gnd Lift switch to its’ inner position to disconnect the ground from the 
output.
Note:

 You cannot use the 48V phantom powering option when the 

ground is lifted! 

    The EBS MicroBassII features a speaker simulator for the balanced 
output. This feature is tuned together with a speaker cabinet in order to 
send the same sound image from the preamp as heard on stage. To 
activate this function press the Spkr Sim switch.

VOLUME

 - The VOLUME knob controls the output volume for the 

OUTPUT and PHONES outputs. The balanced output (XLR) is not 
affected by the setting of this knob. 
__________________________________________________________

HEADPHONES

 – The headphones output enables you to use the 

MicroBassII as a rehearsal amp, or to play without a poweramp/speaker  
cabinet configuration. When using the headphones you should not use the 
48V phantom power option due to the high power consumption.
