AEQ AoIP Users Manual

3.3.2. AEQ Audio over IP system for medium to large sized stations.

This drawing represents a proposed installation of a medium to large sized radio station. The main wiring for IP is represented in pink, using an IP switch or group of switches when the wiring is disperse or distributed in different zones or floors.

The backup IP wiring is represented in green. It can be easily installed through a second IP switch or group of switches (when the wiring is dispersed or distributed in different areas or floors of the building). All devices in the “AEQ Audio Over IP Routing System” feature two network interfaces that allow optional installation of system redundancy. To complete this redundancy, the PCs must be equipped with a second Ethernet adapter.

IMPORTANT NOTE:

When there is a redundant network, primary and secondary interfaces must be connected to separate networks.

The schematic shows the 5 different AoIP interfaces in the AEQ system:

• NETBOX 32 Channel interface.

• NETBOX 8 Channel interface.

• CAPITOL IP console.

• FR14 boards to connect FORUM and GRAND FORUM mixing consoles.

•

BC2214/BC2224 boards to connect ARENA consoles and BC2000D / TITAN routers.

The program audio for all studios, as well as other required signals for the central control (such as clean-feed auxiliary sends for telephone systems, etc) are sourced from the NETBOX 32 AD audio outputs. The signals necessary for the studios, such as satellite downlink, audiocodecs, tuners or TV receivers, etc. are routed to the NETBOX 32 AD inputs.

One or several NETBOX 32 AD units can also be installed in the links dispatch. From this can be extracted, for example, signals going to radio links and satellite uplinks. Audio signals from the central control will be channeled into the system through them. Programs from all the studios (as well as any other signal required in central control such as auxiliary program sends orclean-feeds for telephone systems) are available on the NETBOX32 AD audio outputs.

Signals required as studio channels such as satellite down-links, mobile units, etc. are connected tot the NETBOX 32 AD audio inputs.

A NETBOX 8 AD can be installed in News recording cabins or edit suites providing audio input and output for the audio workstations through a bi-directional USB link. Audio can also be provided to the mixing console using analog and digital I/O connections.

The same NETBOX 8 AD unit will provide IP connectivity to analog or digital studios without

AEQ IP connectivity. This way, a station can be IP–connected without having to abandon existing equipment.

AEQ CAPITOL IP, FORUM and ARENA digital consoles can be provided with the corresponding multi-channel interfaces: One with 16 input + 16 outputs for CAPITOL IP and one or more with 32 input + 32 outputs for FORUM and ARENA. The most important outputs of each console can be routed to the multi-channel interfaces: master, auxiliary, clean feeds, etc. so they can be used at any other location within the station. At any moment and as required, it is possible to assign and route the signals with origin from studios, cabins, central control and links to the audio inputs of the interface.

The installation, turn-on, monitoring, routing creation and optimization tasks are equivalent to those described in the corresponding paragraphs in section 3.1, except for the differences related to the size and complexity o the system.
