In order to make installation process easier, AEQ offers specific pre-fabricated cable kits for
AEQ FORUM LITE audio input/output, both analog and digital, as well as studio headphones:
FR CAB INP, consisting in a male DB15 connector soldered to 4 balanced and shielded 6
meters long paired cables with no connectors at the other end, for 4 inputs or outputs. For more
information please check section 2.2.5 of this manual.
AEQ can upon request provide fully finished cables and in special lengths. For more information
please refer to AEQ sales department or authorised distributors.

Programming digital outputs as S/PDIF.
In order to provide outputs to S/PDIF equipments, the programming procedure
described below adapts the levels and unbalances the signals by joining OUT1- ,
OUT2-, OUT3-, and OUT4- to their corresponding GND, so the signal is taken from
each OUT+ to OUT– (or GND).
Start by following the steps detailed at section 2.2.3.1 (it's
VERY IMPORTANT
to turn
first the equipment off and disconnect the power supply cable). Then, at the "DIGITAL
INPUTS AND OUTPUTS PROGRAMMING ZONE", you can change the outputs one by
one from AES/EBU to S/PDIF by moving the 4 jumpers associated with each output
from position 1-2 (up) to position 2-3 (down), as shown in the following image:
IMPORTANT NOTE:
Regarding the wiring, the chassis of microphones must be connected to
the chassis of the console frame in order to protect the microphone inputs against uncontrolled
static shocks. Pin 1 (Ground) must be connected to the metal case of XLR connector in the
available terminal for this purpose, so any static shock will be downloaded to ground through
the frame chassis. This rule must be followed in every connector throughout the cable in case of
connections by means of aerial connectors. In the same way, for AES3 or USB digital signals,
the chassis of PCs or other digital audio devices must be also connected to the chassis of the
console frame.
