IMPORTANT NOTE: Do not connect this output to any device but the control and
monitoring module
(there is a severe risk of damage to other equipment or even the audio
engine itself). In order to avoid any damage to the unit is
VERY IMPORTANT
to turn off the unit
before connecting or disconnecting this cable.
The audio output for
CUE
or prelisten is also located in this area. See section 2.2.2.4 in this

headphone and external speaker outputs, general purpose inputs and outputs, control and
studio speakers.
Among these auxiliary console inputs and outputs, you can find not only analog signals such as
headphones, speakers or CUE, but also physical general purpose inputs and outputs GPIOs
(both open-collector and relay switched), virtual GPIOs over IP network, and finally the control
and configuration interfaces with an external computer running the associated setup and remote
control software.

Associated electronic with opto-coupled GPI
In order to make installation process easier, AEQ offers specific pre-fabricated cable kits for
AEQ FORUM LITE data input/output within the optional modules range: CP CAB GPIO,
consisting in a male DB15 connector soldered to a 6 meters long cable with no connectors at
the other end. For more information please check section 2.2.5 of this manual.
