1. INTRODUCTION.
1.1. Fields of application of the product.
Using off-the-shelf routing equipment to send audio over IP in small to medium-sized systems
offers cost advantages over synchronous solutions using AES-10 (MADI) or TDM buses. These
have higher capacity, but require powerful hardware. Besides, large TDM systems can reduce
their cost and at the same time increase their flexibility when they are combined with IP audio
links to connect a few circuits with a central router.
That’s why, when developing the IP audio routing system at AEQ, we have created not only IP
connection devices for the consoles, but also connection panels that allow for audio input and
output installation wherever it’s necessary, as well as access boards for the AEQ BC2000D
router.
On the other hand, AEQ insists on offering interoperability with third party devices for the
convenience of our customers. Because of that, the solution we now present is based on
AUDINATE’s technology that is operating with extraordinary performance, making our systems
100% compatible with a wide selection of equipment for Broadcast, Recording Studios and
Professional Audio (see full listing at

1.2. Description of NETBOX 4 MH audio interface.
It is an audio-over-IP multichannel interface used to insert and extract signaling and audio
channels to/from a Dante system, especially suitable for booths and other areas where
microphone or line inputs and headphone or line outputs are required.
This product is designed to cover the need for high-quality microphone inputs and headphone
outputs availability outputs, for example in radio and TV studios, stage or multimedia
installations. The multichannel IP connectivity (Audinate DANTE™ protocol) makes the Inputs
of the unit available at any point of the network. As a complementary feature, the unit is
delivering the same inputs and outputs as analogue balanced line Inputs and Outputs.
It features 4 input and 4 output channels. Inputs have XLR connectors and are microphone /
line level selectable by means of switches at the unit’s front panel. All 4 outputs are balanced,
with XLR connectors and line level, and are also distributed to 4 headphone outputs. Each one
can be configured as a stereo pair, which is called “primary” if it takes outputs 1 and 2, or
“secondary” when it is assigned outputs 3 and 4.
It also provides 4 GPIs and 4 GPOs, including a supply pin for external interface power in the
same connector, and a special set of additional, dedicated GPIOs specially designed to connect
control and signaling boxes in radio booths, including 7 opto-coupled GPI and 2 relay activated
GPOs for ON AIR signaling, powered by the Netbox unit.
Audio routing and levels are configured from a real-time control application running on Windows
operating systems.
