Connecting Pro16 devices
With the IF-AV/DM card properly installed and configured,
you can now connect Pro16 monitoring and audio
networking devices. Connecting a Cat-5e cable from the
A-Net output of the IF-AV/DM card to the A-Net In on the
first Pro16 devices starts an A-Net distribution network. No
configuration is required for the Aviom devices.
Pro16 A-Net allows both serial (daisy chain) and parallel
connection topologies. Cat-5e cable connections can be up
to 500 feet (150 meters) between each Pro16 device. Simply
connect A-Net Out to A-Net In on each device. Parallel
connections can be made using A-Net distribution hubs
(such as the A-16D or A-16D Pro). There is no limit on the
number of A-Net Distributors or A-Net audio devices that
can be used in a system.
CAUTION
Do not use shielded Cat-5e cables with A-Net devices. Be
sure to use only standard Cat-5e cables, not those sold as
crossover cables. A crossover cable is not compatible with
the IF-AV/DM or Aviom equipment.
Series connections
The diagram above shows an IF-AV/DM card installed
connected in series to a group of A-16II Personal Mixers.
Any number of A-Net devices can be connected in this
manner. Cables runs can be up to 500 feet, 150 meters long
between devices. Each A-16II Personal Mixer should be
individually powered.
Parallel connections
Parallel connections avoid some of the pitfalls of a
serially-connected system. Each A-Net device is directly
connected to a data source instead of depending upon the
previous user in a daisy chain for data delivery.
The preceding diagram shows an IF-AV/DM card connected
to an 8-port A-Net distributor. The A-16D Pro distributor
shown allows up to eight simultaneous parallel A-Net
connections. With this arrangement, power is also supplied
to each A-16II personal mixer over the CAT-5e cable.
About Pro16 A-Net
A-Net is Aviom’s proprietary high-speed data transmission
protocol designed specifically to transport uncompressed
high fidelity streaming audio in real time over inexpensive
Cat-5e cabling.
A-Net as implemented in Pro16 products transports sixteen
channels of digital audio (44.1kHz or 48kHz, 24-bit) from
the IF-AV/DM card to each Personal Mixer or AN-16/o
Output Module connected to the system. An unlimited
number of Pro16 A-Net devices can be connected to a
system. A-Net’s proprietary design delivers ultra-low
latency (less than 1 msec from analog input to analog
output) in all configurations.
CAUTION
A-Net is based on the physical layer of Ethernet, which
provides Pro16 A-Net a mature and robust base on which
to build. However, Aviom products are not compatible
with off-the-shelf computer products designed for
Ethernet networks such as hubs, routers, and switches.
Cable lengths
Your cable length performance will be affected by a number
of factors including the quality of the cables used, and the
number of devices such as cable couplers used or wall panel
interconnections in use.
To go longer than the maximum specified distance A-Net
allows (500 feet, 150 meters), an A-Net Distributor product
can be used as a signal repeater. Simply insert the A-16D or
A-16D Pro into the A-Net stream at the 500-foot point and
the A-Net signal will be refreshed.
Another 500 feet (150 meters) of cable can then be added.
This process can be repeated as many times as required to
extend cables.
In fact, any Pro16 A-Net device that has an A-Net out
connector can be used as a signal repeater.
