The AV-M8 Mic Input Module provides eight mic-level inputs to a Pro16 system. Two channels also include a 20dB switchable pad for line-level inputs. Eight channels of digital audio may also be input via ADAT®, from a second AV-M8 module. The unit may be mounted in a rack or to a table or podium, using the reversible mounting flanges or detachable rack ears.
Analog audio is input via eight latching 5.0mm Euroblock connectors. Each analog input channel features configuration DIP switches for individually selectable gain settings, +48V phantom power, and low cut filter.
Analog input channels are routed to Channels 1-8 in the A-Net® stream, while channels input via ADAT become A-Net Channels 9-16. Stereo linking for all eight A-Net channel pairs is supported through an eight-position rear-panel DIP switch.
A-Net connections include A-Net Out and A-Net Expansion, using locking Neutrik® EtherCon® connectors. The A-Net Expansion jack allows up to 32 channels to be carried on a single Cat-5e cable, in either 32x0 or 16x16 configurations. Larger systems (up to 64 channels on a cable) can be built using Aviom's AN-16SBR System Bridge. Pro16 A-Net supports Cat-5e cable runs up to 500ft/150m between devices. For installations requiring longer cable runs, single- or multi-mode fiber optics may be utilized, using certain standard third- party media converters.
The AV-M8 is compatible with all Pro16 Series products.

Click image to enlarge Four performers have individual control of up to sixteen channels of audio drawn from the console. Performers can listen to their mixes with headphones, IEMs, or powered wedges. The A-16D Pro A-Net Distributor supplies digital audio data and DC power to the individual Personal Mixers.
Click image to enlarge Up to 8 conference mics are connected to an AV-M8 Input Module. Audio signals are converted to digital and are output as A-Net data. A-Net from the input module connects to an AN-16/o Output Module in the equipment room using Cat-5e cable.
Individual analog line-level audio channels from the AN-16/o connect to a DSP device for processing. The output from the DSP feeds a power amp which sends the processed audio to ceiling speakers.
Click image to enlarge Two AV-M8 input modules are cascaded via the built-in ADAT® digital connection to create a single 16-channel A-Net stream. Up to 8 conference mics can be connected to each AV-M8 input module. Additional audio from line-level sources such as a CD or DVD player, computer, video system can also be connected to the AV-M8; it has built-in pads available on channels 1-2 for just this purpose.
The two AV-M8 modules in this system are connected digitally to create a single 16-channel A-Net stream. A single Cat-5e cable from the AV-M8 connects to an AN-16/o Output Module in the equipment room. The line-level audio outputs from the AN-16/o connect to a DSP processor. The output from the DSP feeds a power amp that sends the processed audio to ceiling speakers.
An optional RS-232 remote control can be added to the DSP device.
Click image to enlarge This system illustrates the flexibility of A-Net based systems. By using an AV-M8 Mic Input Module connected to an A-16R rack-mount mixer, a very simple portable PA system that anyone can operate can be created.
Because the system uses Cat-5 cables to move audio (and, optionally, mix control), set-up is quick, and the wiring is unobtrusive in any environment. Use the A-16CS for simple, cost-effective mix control or a third-party RS232 control system for more advanced control interface options.
Click image to enlarge Here's a simple PA system that can be used in the gym for a multitude of purposes, from sporting events and pep rallies to meetings, assemblies, and large classes. The A-16R makes the perfect mixer for these applications. Its simple user interface coupled with 16 preset memory locations make it adaptable to almost any sound reinforcement situation.
With remote controllability using a dedicated controller like the A-16CS or via RS-232 control systems, this system packs a lot of power into a small package.
The AN-16/i-M shown can be used for up to 16 mic/line inputs, or substitute the AV-M8 Mic Input Module for an 8- channel variation.
A basic conference system requires one A-Net input module, such as the AV-M8, and one A-Net output module connected with Cat-5e cable.
Inputs to the AV-M8 can come from a mic- or line-level analog source. Two channels include a 20dB switchable pad, supporting line-level inputs from computers, CD or DVD players, etc, while the remaining six are mic-level only.
The AV-M8 is designed to be easy to install and configure. Audio inputs feature latching 5.0 mm Euroblock connectors that require only a small screwdriver when connecting wires. Gain for each analog input channel is individually configured with DIP switches; each channel also has +48V phantom power and a low cut filter.
With detachable mounting flanges and reversible rack ears, the AV-M8 can be placed in close proximity to the mic inputs at a table or podium, in an equipment closet, or secured in a portable rack.
Two AV-M8 Input Modules can be cascaded to create a single 16-
channel A-Net stream by using the built-in ADAT® Lightpipe connections. Once the two AV-
M8s are connected with a standard Toslink optical cable, a single Cat-5e cable can be
connected from the second AV-M8 to any compatible Pro16 output device. Pro16 A-Net
supports Cat-5e cable runs up to 500ft/150m between devices.
Pro16™ Series input and output modules include A-Net Expansion jacks, which can be used to combine to 16-channel Pro16 A-Net streams onto a single cable.
To use A-Net Expansion jacks, first connect one pair of input and output modules as normal (A-Net Out on the Input Module to the A-Net In of the Output Module). Next, connect the second set of input and output modules to the A-Net Expansion jacks on the first pair. All 32 channels (32x0 or 16x16) will be transported on the original Cat-5e cable connecting the first pair of devices.
To transfer up to four Pro16™ A-Net® data streams using a single Cat-5e cable, the AN-16SBR System Bridge can be added. The AN-16SBR features heavy duty EtherCon® connectors on all ports and is sold in pairs.
The AN-16SBR has four ports labeled A, B, C, and D that are used to connect individual 16-channel A-Net streams. The 5th port, labeled Bridge, carries the combined four-stream/64-channel signal.
Each named port on the AN-16SBR has a direct relationship to the same-named port of the opposite half of the System Bridge. For example, whatever A-Net stream is connected to port A at on the input side of the bridge will appear at the matching port on the output side (A to A, B to B, etc.)
The direction of each 16-channel stream is independent, so reversing the direction of a given stream is as simple as switching an input module and an output module. Using the AN-16SBR in this manner supports bidirectional configurations up to 32x32, 48x16, and 64x0 on a single cable.
The AN-16SBR System Bridge is not compatible with Pro64 products and cannot be used with Pro16 A-Net streams that include DC power from an A-Net Distributor.
