frequencies above are stereo. At the next position 
frequencies below 200Hz are made Mono. At the last 
position all frequencies are Mono. 
 

2.7 Balance 
 

This control allows a fine control over the left / right balance 
of the Fat Bustard. This can be very useful in correcting 
any discrepancies of outboard equipment that may be 
slightly misaligned with respect to the level of the left and 
right hand signals.

  

 

2.8 Output Level 
 

This control is a rotary switch that governs the final output 
level of the Fat Bustard. The switch is a high quality Elma 
switch and gives a smooth precise result. 
 

2.9 Monitor 
 

This controls the level to the monitor output, which is 8 dB 
lower than the main output. It is switchable (INT/EXT) 
between the Fat Bustard output and an external input, and 
it is intended that this can be used to compare the original 
signal to the playback from the equipment used for the final 
master. This is especially useful if a compressor (eg. a 
Phoenix) is inserted after The Fat Bustard. 
 
There is a pre-set adjuster near the External Input jacks 
which determines the level of signal from the External 
Inputs. This should ideally be set up with a tone so that INT 
= EXT in level with any inserted equipment in bypass. It 
requires an “electrical” type flat-bladed screwdriver.
