AEQ FORUM - DIGITAL AUDIO MIXER FOR BROADCAST APPLICATIONS

NOTE: For more information about each of these modules, audio inputs and outputs please

refer to section 2.2.3 of this manual.

4.2.1.2. Section INTERNAL CONFIGURATION MODULE

The section INTERNAL MODULE CONFIGURATION of the HARDWARE CONFIGURATION

sub-menu allows you to configure the General Purpose Inputs and Outputs - GPIO (both the

physical contact relays and the opto-coupled that are available on the rear panel in the section

of common inputs and outputs of the AEQ FORUM (Please refer to section 2.2 .2.1 of this

manual). It also allows to configure the operation of the optional multi-channel communications

module - AES10 MADI (please refer to section 2.2.2.7 of this manual.) .

There are four distinct areas in this section:

1) MADI is an optional communication module within the system common I/O section. This

is a bi-directional fiber-optic multi-channel audio link. The physical interface is a

transceiver and the implemented standard is AES10-2003. This optional module is

accessed through the Advanced Configuration menu by clicking “CLICK TO CONFIG”

and then click again on the “CONFIG” button that will appear. The options for

configuration are:

• DISABLED / ENABLED, enable or disable the MADI interface.

• CHANNELS, select the number of channels to be used – 56 mono channels in

normal MADI mode or 64 channels in extended MADI mode.

• SYNC, indicates if the MADI interface will be master or slave for purposes of

synchronization.

• USED, indicating how many of the 56 or 64 mono channels available are

actually in use.

2) General Purpose Inputs - GPI. AEQ FORUM incorporates 8 opto-coupled GPI on open-

collector transistors.
