Aux  pre/post  insert  /  EQ

      Factory  default  for  the 

mono  channel  pre-fade  auxes  is  pre-insert,  pre-EQ.    This  is 
popular  with  many  users  mixing  monitors  from  FOH.    It  pre-
vents  the  channel  EQ  and  inserted  compressors  affecting  the 
monitor mix.  Move the jumper from A to B to change this to 
post-insert, post-EQ if preferred.  Note that auxes are always 
post-mute.

 

Direct  output  source

      Factory  default  is  pre-fader.  

This is common for live recording to multitrack.  The live mix 
fader movements do not affect the recording.  Move the jump-
er from C to D to change to post-fade.  Post-fade is appropri-
ate when using the output as a direct channel effects send. 

 

Channel Aux pre/post settings

      Factory  default  is 

Aux  1-4  =  switched,  Aux  5-6  =  switched.    You  can  change 
these  settings  for  different  combinations  of  pre/post  or 
switched auxes by cutting and re-soldering the links.  Refer to 
the  system  block  diagram  to  explore  the  possibilities.    Make 
sure you set all mono and stereo channels the same.  We rec-
ommend you only change these settings if absolutely necessary. 

Solder Options: 

Cut tracks with a sharp knife and ensure that any 

cuts don't extend beyond the marked area. Add a solder blob to con-

nect  the  adjoining  pads.  If  you  have  any  doubts  about  this  procedure 

please contact Allen & Heath and we will put you in touch with your 

nearest service centre. 

 

Stereo  Channel  Aux pre/post  settings

     

Factory 

default  is  Aux  1&2  =  switched,  Aux  3&4  =  switched,  Aux  5&6  = 

switched.  Configure as mono channel but connections are using jump-

ers instead of solder links.

 

 

 

Stereo/Mono  aux  source

      The  stereo  channels  can 

feed the auxes with a mono sum of L+R, or be configured so 
that L feeds the odd numbered auxes, and R the even.  This is 
preferred when using odd/even auxes as stereo pairs.  Factory 
default is the mono setting.  

 

Talkback mic +48V

   The factory default is +48V phan-

tom  power  turned  on  for  the  front  panel  talkback  mic  XLR 
input.  The option jumper is behind the TB mic XLR on the L 
Master  board.    If  you  prefer,  phantom  power  can  be  disabled 
by repositioning the jumper to the GND position. 

Note that phantom power should not harm non-powered dy-
namic microphones as long as balanced connections are used. 

  WARNING:    Do  not  connect  unbalanced 

sources or cables to inputs with phantom power select-
ed.  To avoid loud clicks do not press the TALK switch 
when plugging or unplugging the talkback microphone.
