Technical Support - ALLEN & HEATH GL4000 User Manual

Should you have any queries about the GL4000 console automation system please
quote the console model, serial number and software version number in any
communication with Allen & Heath or appointed service agent. The system has been
designed and tested to be reliable under the harsh conditions typical of live sound 'on
the road'. Should a problem be encountered check first that external equipment is
correctly connected and functional (or disconnected to test the console itself), that the
equipment has been correctly set up, and that the mains power is correct for the
console power unit. Error detection systems have been built in to assist with problem
investigation.

The console settings are remembered when power is
removed from the console. A power down circuit detects
falling voltage and writes the settings to non-volatile memory.
On power up these settings are restored. Mains power
fluctuations ('brown-outs') are detected with error code
readout.

The console power unit converts mains voltage to the DC
supply rails required by the console. Each rail has an
associated indicator LED on the front panel. If a power rail
fault is suspected check that these LEDs are correctly
illuminated. Note that the optional RPSD2 dual power supply
monitor includes further power supply status monitoring.
