INPUT A 

- A very low noise input suited for all types of instrument. The 

very high impedance (10Mohms) makes this input suitable for sensitive 
piezo pickup systems. This is the default input. 
__________________________________________________________ 
 

GAIN

 - Control to adjust the instruments' signal strength to the right 

operating level in the EBS MicroBassII. This control goes from unity gain 
all the way up to 30dB with low noise. For best results, always try to gain 
from minimum position.

THE FILTERS: 

 
The MicroBassII is equipped with very efficient filter controls to help you 
shape the sound further. 
 

BASS and TREBLE FILTERS: 

 

 

BRIGHT

 – The bright is an advanced high pass filter capable of 

producing bright high treble timbre, without adding practically any noise. 
It gives 12dB boost at 10kHz and may give brightness to old passive 
pickups.  
__________________________________________________________ 
 

ENHANCED FILTER MODE

 – The enhanced mode switch allows the 

Treble control to have effect on the midrange in this filter. When boosting 
the treble, the middles will be cut and vice versa. This function is fully 
separated from channel B’s MIDDLE filter.
