Conventions Used in this Document

AN-Series

The AN‑16/o Output Module, AN‑16/i‑M Mic Input Module, and AN‑16/i Input
Module are referred to generically as the AN-Series of products.

When describing audio network configurations, the AN‑16/i‑M Mic Input
Module and most Pro16 console cards can be substituted anywhere the AN‑
16/i is used.

Using Personal Mixers

It is possible to create an audio distribution and personal monitor system
using any combination of Aviom AN‑Series and Personal Mixer products,
including the A‑16II, and A‑16R.

When referring to the use of the personal mixers in system in general, the
terms A-16II Mixer or Personal Mixer are used to describe a case where a
standard A‑16II Personal Mixer or a rack mounted A‑16R Personal Mixer (with/

1AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

without the optional A‑16CS Control Surface) can be used.

Cat-5 Cables

In most cases Cat‑5e and Cat‑6 cables can be interchanged. When speaking
about interconnections between components in a system, the term Cat-5 is
used generically to indicate the use of any of the applicable cable types.

A-Net Distributors

About A-Net

The Pro16® version of A‑Net® is a high‑speed data transmission protocol
capable of sending and receiving high‑quality digital audio using readily
available Cat‑5 cables. A‑Net is a proprietary technology developed by
Aviom.

A‑Net is based on the physical layer of Ethernet, a Local Area Network (or
LAN) technology. This provides A‑Net with a mature and robust base on
which to build. However, it is important to note that A‑Net devices are not
compatible with Ethernet devices.

As used in the Pro16 series products, the A‑Net signal carries sixteen channels
of digital data from the Pro16 input module (AN‑16/i, AN‑16/i‑M, or console
card) to each A‑Net device connected to the system.

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•
An unlimited number of A‑Net devices can be used in a •

system

3AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

Ease in spanning long distances between system compo‑•
nents

P No t e : While the Cat‑5e cables and connectors used on your Aviom

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

Compatibility with Pro64

Many Pro16 products can be connected to a Pro64® A‑Net system with the
addition of the ASI A‑Net Systems Interface. The ASI translates Pro64 A‑Net
data into Pro16 data and separates the 64‑channel Pro64 stream into up to
four 16‑channel Pro16 outputs, depending on the Pro64 sample rate being
used.

Only Pro16 devices that have an A‑Net In port such as Personal Mixers, A‑Net
Distributors, and output modules are compatible with Pro64 and the ASI.
Pro16 input modules and console cards cannot send their data into a Pro64
network.

What is Category 5?

Category 5 (sometimes referred to as Cat-5) describes a commonly used type
of high performance network cabling. It is used mainly for data transmission
purposes to connect computers, modems and other devices. A standard
Category 5 patch cable consists of four twisted pairs of copper wire terminated
by RJ45 male connectors. The cable assembly is used to provide connectivity
between any two Category 5 female outlet jacks. A variation, called Category
5e (or Cat‑5e), uses additional twists in the cable to reduce interference in
high‑speed network applications. In general, when using long cable lengths,
select Cat‑5e cables for best performance. Use Cat-5e Unshielded Twisted

Pair (UTP) cables or better for all A-Net applications.

The RJ45 connector looks similar to the connectors found on a telephone
system, only larger. The twisting of the wire pairs helps to shield the cable
from unwanted interference from electrical fields or radio interference
(sometimes referred to as “RF”). Cat‑5 cabling supports frequencies up to 100
MHz and speeds up to 1000 Mbps.

4AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

RJ45 Jack Cat-5 Cable

Cat-5 Cables

The cables used with your Aviom system are interchangeable with any
standard Category 5e (Cat‑5e) cables. If you need a longer cable for a
particular application, any computer store should be able to supply you with
an appropriate cable. A qualified technician should be able to build custom
cables to any length (up to the maximum of 500 feet (150 meters) between
components).

For fixed or permanent installations, you have the option of running Cat‑5
cables inside walls and terminating them with readily available wall panel
connectors that include the RJ45 jack. (Solid wire is recommended for
permanent installations.)

In addition to standard Category 5e cables, Category 6 (Cat‑6) cables can also
be used.

P No t e : When purchasing Category 5e cables, be sure to buy only standard

Cat‑5e UTP cables, not those sold as crossover cables. A crossover
cable is used for file transfer between two computers. A crossover
cable is not compatible with your Aviom equipment.

Cable Lengths

Cat‑5e cables used with your Aviom products can be up to 500 feet
(approximately 150 meters) in length between devices. The maximum cable
length specification applies to the cable connected between the Pro16 input
module and the first Pro16 output module (or Personal Mixer) in your system
as well as for cable runs between each additional Pro16 A‑Net compatible
device in your system.

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 passive wall panel interconnections in use. Use Cat‑5e
cable for best performance wherever possible. Stranded or solid Cat‑5e cable
can be used.

When using the optional AN‑16SBR System Bridge, the cable length
specification applies to the total cable length between the two A‑Net devices
being connected with the AN‑16SBR System Bridge. This is similar to what
happens when using an inline coupler to extend cable lengths.

Total cable length c alculations include cables used top connect I/O modules to

System Bridge s.

Pre‑made cables in a variety of lengths and colors are available at most
computer outlets. Cables can be extended by using a simple passive device

6AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

called an inline coupler to add length to existing cables (as long as you do not
exceed the specified maximum cable length). If you need a longer cable on
occasion, this is a simple solution. Note that it is possible that the maximum
cable length specification can be compromised by using inline couplers or
other passive connection devices.

AC Line Conditioning

Aviom products are digital devices and as such are sensitive to sudden spikes
and drops in the AC line voltage. Changes in the line voltage from lightning,
power outages, etc. can sometimes damage electronic equipment.

To minimize the chance of damage to your equipment from sudden changes
in the AC line voltage, you may want to plug your equipment into a power
source that has surge and spike protection. Power outlet strips are available
with built‑in surge protection circuits that may help protect your equipment.

Other options for protection of your equipment include the use of an AC
line conditioner or a battery backup system (sometimes referred to as an
uninterruptible power supply, or UPS).

Power Supplies

Your Aviom product uses a DC power supply that has a two‑prong power
cord. The prongs on the power supply are identical, meaning that there is
no need to orient the plug in a specific direction in the power outlet. Some
products with two‑prong power cords have polarized plugs that can only be
inserted into an electrical outlet one way.

The power supply that is shipped with your Aviom product is a universal
switching type. It is capable of working with voltages from 90 to 240 volts AC.
This means that a separate power supply is not needed to use the products
with the AC power systems found in most countries. You should always use
the power supply that shipped with your product. When travelling, you may
need plug adapters to use the power supply with the AC outlet plug shape
variations in use throughout the world.

Should you need to replace the power supply that came with your product,
we recommend using only a power supply that meets the following
specifications.

Note that polarity of the plug found on the DC power supply needs to match
that of the original power supply that came with your Aviom equipment.
Aviom products use a center positive power supply. The outer contact is
negative, the inner contact is positive. (See the diagram above.)

Power Supply Polarity

Installing in an Equipment Rack

The AN‑16/o Output Module is designed to be installed in a standard 19‑inch
audio equipment rack. This design is both for easy transportation of the unit
and for protection. Each unit takes up one standard rack space (19 inches
wide by 1.75 inches high). Optionally, you can place the units on a table top
or other flat surface such as a shelf.

The rack ears on each side of the device are designed to support the weight
of the AN‑16/o without additional hardware. Each rack ear contains holes for
two screws per side. Always support the unit with all four screws.

To rack mount the AN‑16/o, position it in the equipment rack at the desired
location. Use standard rack‑mounting screws (10‑32 size) to attach the unit to
your rack hardware. Tighten all four screws firmly, but avoid overtightening.

You may want to use non‑metallic washers between the rack‑mounting
screws and the device’s finished surface to avoid marring the painted finish
on your Aviom products.

Always allow adequate ventilation for devices mounted in equipment
racks. Avoid placing your Pro16 product directly above or below other rack‑
mounted devices that produce high levels of heat, such as power amps.

8AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

EtherCon Connector

Some Aviom products use EtherCon® Cat‑5 connectors. The Neutrik EtherCon
connector is a dual RJ45 type connector. It can receive a standard Cat‑5e
cable or a cable fitted with the special heavy‑duty EtherCon connector.

When using a standard Cat‑5e cable, plug the cable into the center of the
jack; release the cable by pressing on the small plastic tab built into the cable
connector.

The locking EtherCon connector is similar to an XLR cable, the kind commonly
used on microphones. Insert an EtherCon equipped cable into the jack until
it clicks and locks in place. To remove the cable, press on the metal release
tab at the top of the panel‑mounted EtherCon jack and pull the connector
outward.

Cleaning and Maintenance Information

The exterior of your Aviom products should be cleaned with a dry, soft, lint‑
free cloth. For tougher dirt, you can use a cloth slightly dampened with water
or with a mild detergent.

When cleaning your Aviom products, never spray cleaners directly onto the
product surfaces. Instead, spray a small amount of the cleaning solution onto
a clean cloth first. Then use the dampened cloth to clean the product.

P No t e : Never use solvents or abrasive cleaners on the finished surfaces of

your Aviom products.

AN-16/o Output Module Front Panel

The front panel of the AN‑16/o Output Module contains the channel Output
Level switches, Signal Present LEDs, Clip LEDs, the A‑Net LED, and the Power
indicator.

The AN-16/o front panel

Channel LEDs

The sixteen numbered Channels on the AN‑16/o front panel correspond to
the line‑level analog audio outputs on the rear panel. Each Channel contains
two LEDs, one showing that there is an audio signal present, and another
used to indicate that the channel’s input source is clipping. Signal and Clip
LEDs appear directly above the Channel numbers.

The lower LED, marked Signal, will light as long as an audio signal of at least
‑40dB is present on the channel. It provides an easy way to confirm that
audio is present on a channel of the AN‑16/o Output Module.

The upper LED is marked Clip. It will light if the input signal coming into your
Pro16 input module (AN‑16/i or AN‑16/i‑M Input Module, console card, etc.)
is too high, causing the audio outputs of the AN‑16/o to sound distorted. In
general, you want to operate the system so that the Clip LED on the Pro16
input module lights only occasionally. If the LED is on constantly, you should
either lower the volume of the source audio coming into the input module
or try different Input Level settings. When using a compatible Pro16 console
card as the input module, avoid clipping the host console’s inputs.

12AN-1 6/o ou t p u t M od u l e us er Gu i d e

Output Level Switches

The AN‑16/o has been designed to work with a wide range of professional
audio gear. There are four Output Level settings available on the front panel
—mic level and +4dBu, +18dBu, and +24dBu line level.

The Mi c setting is appropriate for use with the mic preamp input on mixing
consoles, audio interfaces for DAWs, etc. Use this setting if the device you are
connecting to has no available line‑level inputs.

Output level switches on the AN-16/o aect a pair of channels at a time.

Choose a line‑level output level setting based on the receiving device’s
maximum input level before clipping. Check the specifications of your audio
gear if you are unsure about its maximum input level. Although you won’t
harm the AN‑16/o or your audio devices by using an incorrect level setting,
you do want to avoid sacrificing signal‑to‑noise ratio or distorting the audio
that passes through the system.

A-Net Out

The A-Ne t ou t jack is used to connect the incoming digital A‑Net data to
another A‑Net device. This will send the same sixteen audio channels being
used by the AN‑16/o Output Module to the next A‑Net device, creating
a digital split. An unlimited number of A‑Net devices can be connected in
series using this method. Any A‑Net device, including the A‑16D or A‑16D Pro
A‑Net Distributors can be connected here.

A-Net Expansion

The A-Ne t e x p A N s i o N jack is used when a 32‑channel system is created by using
two AN‑16/i (or AN‑16/i‑M) Input Modules and two AN‑16/o Output Modules.
Using A‑Net Expansion allows thirty‑two channels of audio to travel down a
single Cat‑5 cable, up to the maximum of 500 feet, 150 meters.

Audio Outputs

The DB25 multipin outputs on the rear of the AN‑16/o Output Module can be
used with any device that can accept a mic‑ or line‑level audio output, such
as mixing consoles, wireless transmitters, recording devices, and powered
speaker systems.

A-Net Connections

In a simple Pro16 system, the easiest connection method uses what is called a
daisy chain. That is, each A‑Net device is connected in series. The first device
in the chain receives the A‑Net signal from the Pro16 input module such as
the AN‑16/i Input Module or a compatible Pro16 console card. Each successive
A‑Net compatible device gets its A‑Net connection from the A‑Net Out jack
of the device preceding it in the chain.

Series Connection of A-Net Devices

The diagram below illustrates a series connection of A‑Net devices.

The A-Net Out port on the rst device connects to the A-Net In port on the
next, and s o on.

There is one drawback to this connection method, however. If one A‑Net
device in the chain is disconnected from the A‑Net signal chain, all units
beyond this point will not get any audio until the unit is reconnected to a
valid A‑Net source.

A parallel A‑Net connection solves that problem. By using the optional A‑16D
or A‑16D Pro A‑Net Distributor, parallel A‑Net connections are possible. In
fact, any combination of series and parallel connections can be used to solve
even the most complex audio routing problems.

Parallel A-Net Routing

Connecting A‑Net devices in parallel involves the addition of an A‑Net
distributor. Any number of A‑Net distributors can be added, creating an
infinite number of digital splits.

Using an A-16D A-Net Distributor

A variety of A‑Net compatible components are shown connected in parallel
to an A‑Net Distributor in the diagram below.

The A-Net signal from the Distributor is connected to each A-Net compatible
device with a Cat-5e cable. Removing one A-Net device has no eec t on the
other A-Net ou tputs being used.

Multi-Channel Systems

When more than sixteen channels of audio are required in a Pro16 digital
snake or audio distribution network, there are several options available.
Systems using sixteen or thirty‑two audio channels can be configured with
no additional hardware using the built in A‑Net Expansion port. For systems
larger than thirty‑two channels, Aviom offers the AN‑16SBRR System Bridge
as an option. The System Bridge allows up to four A‑Net streams to be
combined into a single Cat‑5e cable for distribution over long distances.

32-Channel Systems

Aviom’s products work in modules of sixteen channels. Thirty‑two channel
systems can be configured as:

32 channels send by zero channels return (32 x 0 )•
16 channels send by 16 channels return (16 x 16)•
0 channels send by 32 channels return (0 x 32)•

The descriptions above are similar to those used for traditional multi‑core
analog audio snakes. The configurations refer to the number of audio
channels used as inputs on each side of the snake. For example, the “32” in
the 32 x 0 configuration means that 32 audio inputs can be connected at the
stage to send to the front‑of‑house (FOH) mix position. The “0” means that on
the there are no audio inputs used to send audio back to the stage position.

A thirty‑two channel system is comprised of four AN‑Series units, two input
modules and two output modules. Since the system is modular, you can
connect the AN‑Series units as needed, making any of the configurations
mentioned previously available at any time. Simply move and re‑patch the
units.

A-Net Expansion

In a thirty‑two channel system, the A‑Net Expansion jack is used to combine
two A‑Net data streams into a single steam that can travel down one cable.
At the receiving end of the digital snake or audio network, the A‑Net
Expansion jack is used again to separate the data into individual 16‑channel
data streams.

A-Net Out and A-Net Exp ansion ports on the AN-16/i

Some points to remember about using the A‑Net Expansion jacks on the
AN‑16/i and AN‑16/o to create a digital snake or audio network:

When creating a system with four AN‑Series units, one •
A‑Net Expansion jack will be connected to an A‑Net In port
while the other A‑Net Expansion jack will be connected to
an A‑Net Out port.

The A‑Net • Out jacks on the AN‑16/o Output Modules
should be unused when only four AN‑Series units are
being used to create a system. These are then available for
adding extra AN‑16/o Output Modules for digital splits or
for connecting to a Pro16 monitor mixing system.

The cable connecting the two sides of the system (carrying •
thirty‑two channels of audio) should be connected to one
A‑Net In port and one A‑Net Out port.

Do not connect Cat‑5e cables carrying expanded system •
data (more than 16 channels) to an A‑16D or A‑16D Pro
Distributor or Personal Mixer product.

The maximum cable length specification of 500 feet (150 •
meters) applies to the length between an A‑Net In port
and an A‑Net Out port. Cables used to connect devices via
the A‑Net Expansion jacks must fall within this maximum
distance.

An A‑Net Expansion port is • never connected to another
A‑Net Expansion port.

Connecting the System Bridge

Adding a System Bridge to a digital snake is quite simple. Two System Bridges
are needed to create a network. The four A‑Net connectors (labeled A, B,
C, and D) on one side of the digital snake are directly related to the A, B, C,
and D connectors on the other side of the digital snake. That is, if you patch
an AN‑16/i Input Module into port “A” on one side of a System Bridge, an
AN‑16/o Output Module would be connected to port “A” on the other side of
the System Bridge. See the following diagram.

This diagram shows the relationship of the A, B, C, and D ports on the AN-16SB.

A complete digital snake using four units per side follows the same pattern.

When configuring 64‑channel digital snake systems that send data in both
directions, Aviom suggests the following module combinations. While not
mandatory, these suggestions are made to accommodate the standard
wiring practices that Ethernet uses. (Aviom’s A‑Net technology is based on
Ethernet.) Some wire pairs in a standard Ethernet cable are not next to each
other inside the jacket of the cable. This can account for slightly higher data
errors in rare cases.

The configuration recommendations apply to systems configured as 16 x
48 and 32 x 32, not those sending data in only one direction. The module
combinations are applicable especially when using long cable runs.

For 16 x 48 (or 48 x 16) digital snake configurations, place the three similar
modules together, connected to either ports A, B, and C on the System
Bridge or to ports B, C, and D, See the following diagrams.

Ports A, B, and C use the same t ype of module.

Ports B, C, and D use the same t ype of module.

For a 32 x 32 configuration, place two similar modules together, connected to
either ports B, and C on the AN‑16SB. The modules connected to ports A and
D are also similar by doing this configuration., See the following diagram.

System Bridge

As mentioned in the section on 32‑channel systems, any available A‑Net Out
jack on a Pro16 A‑Net device can be used to expand an existing system and
create a digital split. Any number of additional AN‑16/o Output Modules can
be added, as can any number of A‑16II or A‑16R Personal Mixers.

The following example shows one variation of an expanded system.

This system includes multiple digit al splits and a monitor sys tem.

This example starts as a 64 x 0 configuration (the input side of the system is
not shown in the diagram). Two of the outputs are expanded. Port A of the
System Bridge has two AN‑16/o Output Modules added. Port D has also two
output modules which then feed an A‑16D A‑Net Distributor.

The A‑16D Distributor connects to five A‑16R rack mounted Personal Mixers
for use as a monitor system for five musicians performing live. Then, another
AN‑16/o Output Module is connected via a daisy chain to the last A‑16R.

Expansion of a system can continue as your needs require. Any available
A‑Net Out can be used to connect to the A‑Net In on any compatible device.

Again, each A‑Net cable used can be up to 500 feet (150 meters) long, making
this system capable of spanning long distances between rooms, floors, etc.
A‑16D Pro A‑Net Distributors can be substituted for the A‑16D.

Expansion of a system can include multiple AN‑16SBR System Bridges. This
allows audio to be fed to different locations as needed. Using multiple System
Bridges follows the same connection rules as outlined previously. (Port A on
one System Bridge always connects data to Port A on another System Bridge,
etc.)

System Bridges can also be used to combine A‑Net streams from multiple
digital snakes or audio networks in an installation, allowing, for example,
ports A and B from Network #1 to be sent along with streams B and C from
Network #2 to a third area, creating Network #3.

A second set of System Bridges move 64 channels of audio over one C at-5e
cable to another destination.

As with all A‑Net compatible devices, any available A‑Net Out can be used as
a starting point for expansion.

the AN‑16/i modules. These include:

The rear panel of the AN‑16/o uses a pair DB25 connectors for its balanced
line‑level audio outputs.

AN-16/o DB25 Audio Connections

The DB25 multi‑pin connectors on the AN‑16/o are wired to analog pinout
standards. This allows easy interfacing with a variety of audio equipment
with the use of readily‑available multipin breakout cables or patch bays.

Each DB25 jack carries eight balanced audio channel outputs.

To wire a custom cable for use with the AN‑16/o DB25 output jacks, use the
following table:

AN-16/o Output Module Variations

Previous versions of the AN‑16/o are compatible with all Pro16 products. The
information provided here details the differences in features of previous
models in order to make the integration of new and old products easy to
understand.

The rst t wo versions of the AN-16/o have -10dBv and +4dBu output levels.

The first two versions of the AN‑16/o (discontinued) have a two‑position
Output Level Switch; in the left position, the channel pair is output at ‑10dBv
line level; in the right position, the channel pair is output at +4dBu line level.

Two variations of this AN‑16/o were produced; the only difference is the type
of connector used on the rear panel for the audio outputs—1/4‑inch TRS or
Euroblocks.

A‑Net connections on the rear panel of the original AN‑16/o use standard
RJ45 connectors instead of EtherCon connectors.

35AN-16 /o ou t p u t Mo d u l e us e r Gu i d e

The third release of the AN‑16/o (discontinued) offered mic‑level and line‑

Mic Line Mic Line Mic Line Mic Line Mic Line Mic Line Mic Line Mic Line

level outputs, switchable in pairs from the front panel; the front panel level
switches are marked Mi c and Li n e on this model. The maximum output level
from the Line setting was +4dBu.

The third version of the AN-16/o can be distinguished by its Mic /Line output
level switches on the front panel.

Audio outputs on this model used two DB25 connectors wired to the analog
audio standard.
