AEQ FORUM
Digital audio mixer for broadcast applications
26
In order to simplify the installation phase, AEQ offers a prefabricated wiring kits for the different
audio inputs and outputs modules available. More information in section 2.2.4 of this manual.
2.2.3.1. FR02 Digital inputs/outputs module.
The AEQ FORUM FR02 module includes 4 AES/EBU or SPDIF stereo digital inputs and outputs
on two DB15 connectors.
The 4 digital inputs on the FR02 are available through a female DB15 connector identified as
“AES/EBU 4 STEREO INPUTS”. The 4 digital outputs on the FR02 are available through a male
DB15 connector identified as “AES/EBU 4 STEREO OUTPUTS”.

The module FR02 includes SRC (Sample-Rate-Converters) for all inputs and outputs. The
digital audio format for each input or output is irrelevant in the process of installation and
configuration since it is being managed automatically and transparently to the user.
By changing some jumpers on the FR02 module you can work with digital signals in SPDIF
format. In the module you can see, for each one of the 4 inputs and 4 outputs, the jumpers
position in order to configure them as AES3 or SPDIF.
