AEQ
Audio Over IP
Routing System
28
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 channelled 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
or clean-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 3.3.1, except for the differences
related to the size and complexity o the system.
3.3.3. AEQ Audio over IP system for medium to large sized stations based on TITAN / BC
2000 D TDM Matrix.
The following schematic shows on the left new elements compared to the previous example:
•
A main matrix to which all audio originating form the Dante network is routed through a
through a bank of BC2214 or BC2224 cards installed in the TDM matrix frame
•
A control network with workstations running layouts of the Real Time Control
Application for the matrix and customized Control panels NCB-100 for the distributed
and hierarchical control from studios and MCR
•
A set of inputs and outputs from the cards installed in the central control (analog, digital,
MADI for connection of third party consoles and other sources...)
We benefit that way from the performance of the TDM system (distributed control and
processing of the crossing points, audio mixing, alarms, macros and salvoes executed manually
or automatically, VU meters, MADI connectivity and E1/T1...) and the ease of installation and
flexibility of an AoIP system.
