NOTE: some headphones could require more volume than the levels that are on tap. Each pair of 
headphones/IEM's are very different from one another and the input impedance of each model 
can vary a lot. In that case, you could be in need of a heaphone preamp.  
NOTE: You could use the headphone output at gigs to send a copy of your guitar sound to your 
personal IEM mix, in order to have total control of your personal volume. Most of the personal 
IEM  system  let  you  to  have  two  inputs:  your  instrument  (that  should  be  carried  by  the  Amp 
Central) and the band, usually carried by FOH or stage mix personnel.  

 
 

 
 
 
 
 
LOOP FX 

 
An effects loop is usually placed between your amp’s preamp and power amp, so this mean 
that only your preamp is processed by the effects, while the power amp is there only to amplify 
the signals. It’s something quite useful for these modern times. 
Some of the older amps had no fx loop, more modern ones, do have one, but in mono.  
 
We decided to place a stereo fx loop in the AMP CENTRAL to let you insert you favorite external 
effects in the chain. The fx loop is placed between the IR LOADER section and the output of the 
Amp Central, so this means you’re sending the already processed amp signal with the Impulse 
Response applied to your fx to be processed. To the most experts out there and also according 
to us, this is the best place to put your effects, but in a superior way than most conventional 
amp fx loops offer.  
Not having the fx through your, speakers but after, would enable the entire audio spectrum to 
go thru them, and not having them heavy band-passed by the speaker itself. 
NOTE: While the SEND section is stereo, only one I.R. can be loaded at a time, for both left and 
right.  SENDS  will  simple  make  a  buffered  copy  for  your  right  and  left  effect  inputs,  to  be 
returned to the stereo RETURNS.  
 
So, what is the advantage of sending the signal in stereo instead of using only one mono send 
and then a stereo return?  
Well,  there  are  no  advantages  at  all  for  a  mono  input  devices,  besides  the  facts  that  some 
effects want to see a stereo input signal to help make their algorithms work in a proper way.  
 
If you have only one channel in your soundcard/mixer left, use only one output as one side of 
the stereo loop, this will work perfectly as you’d mic’d your amp with a single SM57 for esample, 
while placing a delay into your amp’s fx loop.
