INTERNAL LINK OPTIONS
The GL4000 is configured to satisfy most applications that should be
encountered. However, the following internal link options are offered for
those applications that may require alternative settings. These options
require access to the internal circuit assemblies and resoldering of circuit
board links. This work should be carried out by technically competent
personnel. Further information is available in the separately available
service manual and from your Allen & Heath agent.
