Aviom source selection systems can be configured to handle even the most complex
routing and signal distribution scenarios. Aviom's robust A-Net® audio transport
technology eliminates problems caused by noise, hum, ground loops, and 
RF interference.
Design, installation, and setup are simple, and never require complex IT-based computer
programming.
No matter how many channels your application requires, Aviom's I/O modules and network devices can be configured to solve even the most difficult audio distribution problems. There is no practical limit to the size of a system, helping to ensure that an Aviom solution is upgradeable and expandable for years to come.
The stability, flexibility, and simplicity of A-Net keep installation and maintenance costs low, while system expansion is as easy as connecting additional modules.
Click image to enlarge Up to 16 audio sources (any combination of mono and stereo, up to 16 channels) are connected to a Pro16 input module, where the input signals are converted to digital and transmitted as A-Net. The A-Net signal connects to one or more A-Net Distributors, which supply both the digital audio and DC power to the connected output devices, in this case the AV-P2 Output Module.
Users can select any of the input source channels to be monitored by using the rotary selector on the front of the AV- P2.

The A-Net signal connects to one or more A-Net Distributors, which supply both the digital audio and DC power to the connected output devices, in this case the A-16II Personal Mixer.
Users can select any of the input sources to be monitored using the channel buttons on the front of the A-16II, while monitoring with headphones, earbuds, or powered speakers.

This diagram shows a large press room or translation service feed that uses a line-level input module to feed multiple A-Net Distributors. Each distributor can send data and DC power to up to eight units. Monitor stations can also be connected serially, with power provided locally.
Expand the system with additional distributors and monitor stations.
Click image to enlarge This setup is an ideal design for a music teaching lab. Up to eight stereo or sixteen mono keyboards can be used. Combinations of students' and instructors' instruments can be saved to the memory location of the Personal Mixers for easy recall.
With each student performer wearing headphones or in-ear monitors connected to a Pro16 Personal Mixer, everyone can enjoy the feel of playing at full volume without actually making much audible sound.
Connect line-level signals from the keyboards to the A-Net input module. For mic-level signals, choose the AN-16/i-M which accepts both mic- and line-level audio.
The direct connection method is ideal for line-level instruments such as keyboards; no audio mixer is required. Simply patch the stereo outputs of your keyboard into the line- level inputs of the A-Net input module.

Audio from an existing source, such as a mixing console, satellite audio feed, computer, radio receiver, CD, or DVD player, is connected to a Pro16™ or Pro64® Series input module or console interface card. Input modules are available in a variety of configurations and formats, including digital cards for a host of leading console manufacturers. Refer to the Partners section for complete details.
The input module converts the audio to A-Net and outputs an A-Net digital audio stream over Cat-5e. Output modules, mixers, or network devices can be connected as needed.
With an A-Net based system, there is no practical limit to the size of a system; even hundreds of users can be easily accommodated.
Inputs to a Pro16 digital snake or audio distribution system can come from a mic- or line-level analog source or an A-Net compatible console card. Choices for analog input include the AN-16/i (line-level) or AN-16/i-M (mic- and line-level); the Y1 card can be used with Yamaha® digital consoles. Cards for a host of leading console manufacturers are available; refer to the Partners section for complete details.
Simply connect your audio sources, power up the input module or host console card, and connect up to 500ft/150m of Cat-5e cable, and you're ready to select output modules, network devices, or mixers.
Once a signal is converted A-Net, any compatible Pro16 device can be used to convert the digital data back to analog. The AN-16/o Output Module provides line- or mic-level output signals that can be connected to mixing consoles, recording devices, etc.
Unlimited lossless digital splits can be created from any or all output modules in a system simply by connecting another output module with a Cat-5e cable.
Compatible Pro16 output devices include:- A-16II Personal Mixer
- A-16R Rack-Mount Mixer
- AN-16/o Output Module
- AV-P2 Output Module
Inputs to a Pro64 audio network or digital snake can come from mic- or line-level analog sources, an AES3 digital source, or a Yamaha® digital console or mix engine. Any combination of input sources can be used to create a high performance digital network.
Once audio sources are connected, the base A-Net Slot must be set on each device. This setting maps the hardware channels to a corresponding range within the network. For instance, with the A-Net Slot set to 17, channels 1-16 on a 16-channel input module such as the 6416m will be placed in the network in A-Net Slots 17-32. Unlike Pro16™ devices, all Pro64 devices simultaneously transmit and receive the full audio network, so setting the A-Net Slot is essential to managing the network resources and keeping track of your system's audio channels.
Finally, individual inputs must be activated into the network. This is accomplished by pressing the numbered channel button on the front panel of rack-mount devices or, in the case of the 6416Y2 A-Net card, via DIP switches.
A Pro64® network can be connected in almost any way imaginable with no impact on audio performance. Every cable in a Pro64 network always carries the full capacity of the network, meaning that there are no limitations on the location of input or output modules. Pro64 also supports the use of hubs such as the MH10 and fiber-enhanced MH10f when parallel connections are desired.
Because every Pro64 A-Net® port is always bidirectional and carries the full capacity of the network, all of the ports throughout a network are essentially interchangeable. If you plan to operate your system in Manual Mode (up to 64x64), connecting one device's B port to the next device's A port throughout the system will make tracking signal flow in complex systems more straightforward. If, however, your system will always run in Auto Mode, there is no need to keep track of A-Net connections.
The ASI A-Net Systems Interface can be used to connect select Pro16 Series devices to a Pro64 Series network, further enhancing the output options for a system or installation.
The ASI provides a link between Pro64 Series networking products and Pro16 Series output devices, such as the AV-P2 and AN-16/o Output Modules, and the A-16II and A- 16R Personal Mixers. The ASI features two Pro64 network ports and four Pro16 outputs, separated into 16-channel blocks and transmitted out the corresponding Pro16 ports.
The ASI is a plug-and-play module, requiring no configuration beyond selecting a Pro64 network port for Manual Mode systems. The number of available channels and Pro16 ports is determined by the sample rate of the Pro64 network (64 channels and four ports at 44.1/48kH±, 32 channels and two ports at 96kHz±, and 16 channels and one port at 192kHz±). Stereo link settings from the Pro64 network are passed to the Pro16 outputs.
Personal Mixers can be connected in any combination
of serial (daisy chain) and parallel (star) connections. Every Personal Mixer has both an A-Net In and A-Net Out jack, and mixers can be daisy-chained without limit. Every Personal
Mixer is truly plug-and-play: connect it and you're ready to go.
Most users, however, choose to use an A-Net Distributor, such as the A-16D Pro, and connect mixers in parallel. This offers several advantages. First, any time devices are daisy-chained, "downstream" devices depend on upstream devices for their data. If someone unplugs a mixer or knocks over a stand on stage, multiple users may be affected. Second, using a distributor delivers the added convenience of providing power for the mixer over the Cat-5 cable, eliminating the need for extension cords and external power supplies at the mixers. Thus, using parallel connections is both more secure and more convenient.
Distributors can be inserted into the A-Net stream at any point in the system, and there is no limit to the number of distributors in a system.
The diagrams show A-16II Personal Mixers, but any combination of Pro16 output devices can be used, including the A-16R and AV-P2.
