AEQ FORUM
Digital audio mixer for broadcast applications
28
NOTE 2: only when the FR03 module edition is previous to edition 4 and the firmware version of
the CPU module of BASE PBA is previous to 1.44, in case you use a microphone that needs
Phantom power it’s important that you activate that option only when the microphone is already
connected to the corresponding input, in order to avoid unconfigure the gain of the rest of the
microphones (anyway it’s possible to recover those gains configuration just by refreshing the
gain of at least one microphone per module).

The AEQ FORUM FR04 module incorporates 8 electronically balanced monophonic line level
inputs and are available physically through two DB15 female connectors identified as “ANALOG
