Pro16 Series Systems

A complete Pro16 Series audio network system consists of at least one
Pro16 input module connected to a Pro16 output device such as the
AN-16/o Output Module, AV-P2 Output Module, or A-16II Personal Mixer.
Many configurations are possible by using additional input modules
and/or Personal Mixers and output modules.

About A-Net

Aviom’s A-Net® is a high-speed data transmission protocol. It is capable
of sending and receiving uncompressed, high-quality audio using
readily available Category 5 cables. A-Net technology is a proprietary
system developed by Aviom.

A-Net is based on Ethernet, a Local Area Network (or LAN) technology.
This provides A-Net with a mature and robust base on which to build.
However, because A-Net manages data in a way that ensures optimum
performance for audio, Aviom products are not compatible with off­the-shelf computer products designed for Ethernet networks such as
hubs and switches.

As implemented in the Pro16 Series products, the A-Net signal carries
sixteen channels of digital data from a Pro16 input module to a Pro16
network device or output device, such as the AN-16/o Output Module
or A-16II Personal Mixer. (The AV-M8 provides eight channels of digital
data to the Pro16 A-Net stream. Sixteen channels are possible when two
AV-M8 units are cascaded using the ADAT link.)

Some of the benefits of using A-Net to transmit digital audio are:

Virtually no latency

•
No ground loops

•
Easy cabling using readily available components

•
Easy expansion and reconfiguration of systems

•
An unlimited number of A-Net devices can be used in

•
a system

Long distances between system components

•

P Note: While the Category 5 connectors and cables used with

your Aviom products look like typical computer network
connections, do not connect computers, routers, or other
home and business networking equipment to your Aviom
products.
