2.2.1. Power supply.
The power supply module is located at the left of the audio engine back panel (as seen from the
rear). It supplies the internal voltages to the console and to the control surface. It consists on a
universal auto-range switching power supply that can operate with worldwide mains: 90 - 132 V
AC & 187 – 264 V AC, 47/63Hz. The max power consumption is 65VA.
Optionally, a second (backup) power supply can be installed in order to have redundancy. This
second power supply includes installation instructions. If two power supplies are used, it is
recommended that one of them is connected to a UPS while the other can be connected to
regular mains or domestic power.
The console/engine data and power supply interconnection is located at the right of the power
supply inputs. It is designed for use with straight Ethernet cabling, but also carries proprietary
power supply lines.
Please use the cable provided with the unit only.
IMPORTANT NOTE: Do not connect this output to any device but the cotrol surface
(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.
2.2.2. Auxiliary connections.
This area of the AEQ CAPITOL back panel includes a wide variety of inputs and outputs,
required to integrate the unit with any professional audio installation, including several
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 general purpose inputs and outputs GPIOs (both open-
collector and relay switched), and finally the control and configuration interfaces with an external
computer running the associated setup and remote control software.
2.2.2.1. GPIO.
AEQ CAPITOL includes many general purpose inputs and outputs using optocouplers and relay
contacts, all of them made available at the back panel of the audio engine.
