SERVICE OPTIONS
CAUTION
These servicing instructions are for use by qualified service
personnel only. To reduce the risk of electric shock do not
perform any servicing other than that contained in the oper-
ating instructions unless you are qualified to do so.
The XB-14 mixer has a versatile architecture which should satisfy most
applications that you may encounter without modification. However,
the following internal options provide alternative settings for those
applications that may demand them.
Access is required to internal assemblies. There are a mixture of plug-
gable jumpers, cuttable wire links and solder bridge options inside the
unit that can be modified to change mixer functionality.
NOTE: We advise that the modifications below are carried out by
an authorised Allen & Heath service centre. The following information
is provided to give the user an idea of how the console can be modified
if required.
The diagram below shows the mixer with the rear cover removed.
Modifications to the rear mounted boards are relatively straightfor-
ward and can be done in situ. Jumper options on the channel boards
can also be changed with a pair of pliers or tweezers.
Cut and solder links on channel boards are best performed by remov-
ing the relevant channel beforehand.
