The AUX 5-6, L-R-M Masters

 

 

AUX  5  and  6  Masters

      These  function  in  the  same  way  as 

described for auxes 1 to 4.  In monitor mode, the recessed REV switch 
reverses  the  AUX5  master  with  L,  and  AUX6  with  R.    Here  the  aux 
signals are presented to the L and R XLR outputs complete with their 
inserts.  The LR mix swaps on to the Aux TRS jack outputs.  Note that 
the  LR  mix  always  feeds  the  matrix  and  2-track  regardless  of  mode 
selected. 

LR Masters

   Separate 100mm faders control the main mix L and R 

output  levels.    They  provide  +10dB  maximum  boost.    Each  master 
includes a 4 LED bar meter, an AFL switch and a MUTE switch so that 
L and R can be separately monitored and muted.  This is most useful 
in  monitor  mode  where  these  masters  carry  the  AUX5  and  AUX6 
signals. 

M Master

   A 100mm fader adjusts the level of the signal to the M 

output  XLR.    The  master  is  fully  featured  and  includes  a  4  LED  bar 
meter, an AFL switch and a MUTE switch. 

The  M  output  adds  a  true  touch  of  genius  to  the  versatility  of  the 

GL2400

.  The source is selected using two mode switches above 

the R fader.  These are recessed to prevent accidental operation.  Use 
a pen or pointed object to set the position.  

FOH  mode  ––  With  both  switches  in  the  up  position  (flush  with  the 
panel), the post-fade L and R mix are summed together to provide a 
mono source. Use this to feed a mono PA, fill, delay or zone speakers, 
or even a mono broadcast or recording send. 

Monitor  mode  -  Press  the  upper  switch  to  create  an  engineer’’s 
monitor  listen  wedge  feed  from  the  AFL/PFL  mix.    Note  that  in  this 
mode  the  M  AFL  switch  is  disabled.    It  is  common  to  use  a  wedge 
speaker  of  the  same  type  used  on  stage  to  listen  to  and  check  the 
various monitor mixes being sent to the performers.  Together with the 
group/aux  REV  function,  the 

GL2400

  can  be  configured  as  a 

compact yet fully featured monitor console. 

Aux-Fed-Subs mode –– Press only the lower switch to configure M as 
the master for AUX6.  This innovative feature is ideal when driving your 
sub  bass  speakers  with  their  own  mix  fed  from  an  aux,  a  technique 
becoming  more  popular  in  FOH  mixing.    This  mode  provides  all  the 
main PA masters (L, R and SUB) with faders, meters, MUTE and AFL.  
Using the faders you can adjust the level of the main PA without losing 
the balance between the tops and subs. The signal is not affected by 
the AUX6 rotary master.  However, the rotary output can still provide 
another sub feed with its own independent master control. 

Route  all  sources  to  LR  in  the  usual  way  to  feed  the  main  ‘‘top’’ 
speakers.  In addition, route sources with low frequency content such 
as kick drum, bass, keyboards, sound effects to the sub speakers by 
turning  up  the  AUX6  send  rotary  on  those  channels.    Make  sure  all 
channel  aux  5-6  sends  have  been  set  for  post-fader  operation.    Use 
two crossovers, one for the stereo LR mid/top frequencies, the other 
for  the  sub  feed.    Set  the  system  up  so  that  the  correct  balance 
between tops and subs is achieved when the channel send is at its ‘‘0’’ 
(3 o’’clock) position and the L, R and M faders in line with each other. 

Aux-Fed-Centre  mode  ––  The  same  principle  as  above,  but  AUX6  is 
used  to  feed  a  centre  mix  such  as  a  fill  or  C  in  an  LCR  system.    To 
route  to  C  only,  turn  up  the  channel  AUX6  send  to  3  0’’clock  unity 
position, and turn off its assignment switch to LR.
