Down - LINE 2 input feeds the transformers (LINE IN 2 L, LINE IN 2 R on rear panel). This 
allows a balanced line input to be controlled (and driven) with the GAIN controls at the front of 
the signal path.  
PHANT switch - 

Engages phantom power to the mic inputs.  

Note: 

Phantom power can damage certain microphones, and should only be used with 

microphones that require it, so please consult your microphone manufacturer’s 
literature before engaging phantom power. Phantom power is only engaged at the MIC 
IN jacks. Please turn ON phantom power after all connections have been made, and 
please turn OFF phantom power power and wait a second before any connections are 
removed.  
 
8755DM Input Switching 
Three switches are in play when selecting an input, the INST/MIC/LINE 1 switch, the 
MIC-20/MIC/LINE 2 switch, and the ‘floating switch’ underneath bandwidth control. For MIC 
and LINE 2 inputs to work, the floating switch has to be in the LEFT/OFF position. 

 
LINE IN 1 :

 LINE IN 1 is active, MIC IN feeds PREAMP 

OUT. The MIC-20/MIC/LINE 2 switch determines what 
signal feeds PREAMP OUT unless INST is selected, 
which only allows INST to feed PREAMP OUT. 
As shown, MIC feeds PREAMP OUT.  
MIC IN :

 MIC IN is active, MIC in feeds preamp out. 

Useful for capturing a dry signal from the preamp, as 
well as the processed signal from the main LINE OUT. 
 
 
MIC IN -20 :

 MIC IN is active with a -20dB pad before 

the transformer. MIC IN -20 feeds PREAMP OUT. 
 
 
 
LINE 2 IN :

 LINE 2 is active and fed into the mic 

preamp input transformer, LINE 2 feeds PREAMP OUT.  
 
 
 
INSTRUMENT IN :

 INST IN is active, INSTRUMENT IN 

feeds PREAMP OUT.
