When referring to the use of the Personal Mixers in a system in general, the term Personal Mixer is used to
describe a case where an A360 Personal Mixer, A-16II Personal Mixer, or a A-16R Rack-mount Personal Mixer
(with/without the optional A-16CS Control Surface) can be used.
Cat-5 Cables
In most cases unshielded (UTP) Cat-5e, Cat-6, and Cat-6e 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
The A-16D and A-16D Pro A-Net Distributors are referred to generically as A-Net Distributors. Both are
used to copy an A-Net digital signal and split it into multiple copies so that devices may be connected in
parallel.

About A-Net
A-Net® is a proprietary high-speed data transmission protocol developed by Aviom, capable of sending
and receiving high-quality digital audio using readily available Cat-5 cables.
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.
Some of the benefits of using A-Net to transmit digital audio are:
Virtually no latency; analog in to analog out is always less than one millisecond•
No ground loops•
Easy cabling using readily available components•
An unlimited number of A-Net devices can be used in a system•
Ease in spanning long distances between system components•
There are two versions of Pro16 A-Net: the original Pro16 A-Net signal carries sixteen channels of digital
data while the enhanced Pro16e® version of A-Net is capable of carrying up to 64 channels of digital audio
data. Like standard Pro16 A-Net, Pro16e is a point-to-point digital audio protocol.
Pro16e A-Net data is intended for use with the A360 Personal Mixer which can take advantage of the higher
network channel count that Pro16e provides.

About Category 5
The term Category 5 (also referred to as Cat-5) is broadly used to describe a type of high performance
network cabling used for data transmission purposes to connect computer networks and other devices.
A standard 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 Cat-5 female RJ45 jacks.
A variation of the cable, called Category 5e (or Cat-5e), has largely replaced Cat-5 in the field; it uses additional
twists in the cable’s wire pairs to reduce interference in high-speed network applications. Additional
wire pair variations are found in Cat-6 and Cat-6e cables, typically used with gigabit networking devices.
Use Unshielded Twisted Pair (UTP) cables for all A-Net applications.
RJ45 Jack Cat-5e Cable
PNO 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.
Cat-5 Cables
Any standard Category 5e (Cat-5e) UTP cable may be used with your Aviom products. 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.
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.
PNo 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 and is not compatible with your Aviom equipment.

Cable Lengths
For Pro16 applications—connecting one Pro16 device to another—the Cat-5e cables used with your Aviom
products may be up to 500 feet (approximately 150 meters) in length between devices. For example,
connecting an AN-16/i-M Mic Input Module to an AN-16/o Output Module is a Pro16-to-Pro16 connection.

When using Pro16e—such as the A-Net Out from an AN-16/i v.2 to any other Pro16 or Pro16e device—Cat-5e
cables may be up to 400 feet (approximately 122 meters) in length between compatible devices due to the

The maximum cable length specification applies to the total cable length between an A-Ne t Ou t port on
one device and the A-Ne t INport on the next A-Net capable 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 passive devices such as cable couplers or passive wall panel interconnections in
use.
Stranded or solid Cat-5e cable may be used; stranded cable is easier to deploy on a stage while solid
core cable provides slightly better maximum distance performance. Solid core wire is typically used in
permanent instillations in walls and across ceilings.
When using the optional AN-16SBR System Bridge with Pro16 and Pro16e devices, the cable length
specification applies to the total cable length between the two active A-Net devices being connected
with the passive AN-16SBR System Bridge, plus all cables. This is also true when using an inline coupler to
extend cable lengths.
Pre-made cables in a variety of lengths and colors are available at most computer outlets. Cables may be
extended by using a simple passive device 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 the maximum cable length performance 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.
Type Switching
Input Voltage 90-240
volts
50/60Hz
30VA
Output 24Vdc 0.5A
Polarity Outer = negative;
Inner = positive
Plug Size 2 mm
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.

Installing in an Equipment Rack
The AN-16/i v.2 Input 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).
The rack ears on each side of the device are designed to support the weight of the AN-16/i v.2 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/i v.2, 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.
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.
PNo t e : Never use solvents or abrasive cleaners on the finished surfaces of your Aviom products.

The front panel of the AN-16/i v.2 contains the channel information, Mono/Stereo link switches, Signal Present LEDs,
Clip LEDs, A-Net In and Power indicators, and the Input Level switches.
Channel LEDs
The numbered Channels on the AN-16/i v.2 front panel correspond to the sixteen line-level analog audio
inputs on its rear panel. They are grouped together in pairs—Channels 1 and 2, Channels 3 and 4, etc.
Each channel contains two LEDs, one showing that there is an audio signal present, and another used to
indicate that the input to a channel is causing audio clipping. Signal and Clip LEDs appear directly beneath
the channel numbers.
The lower LED, marked SI g N A l , 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 indeed passing into the AN-16/i v.2 and being
converted to A-Net.
The upper LED is marked Cl I p . It will light if a signal reaches a point that is within 3dB of full scale (0dB).
In general, you want to operate the system so that the Clip LED lights only occasionally (the transients of
percussive sources will typically peak for a few milliseconds, for example). If the LED is on constantly, you
should either lower the level of the source audio coming into the AN-16/i v.2 or try different Input Level
settings.
Input Level Switch
The AN-16/i v.2 has been designed to accept a wide range of professional and semi-professional audio
levels. There are four Input Level gain settings available. Changes to the input level on the AN-16/i v.2 front
panel affect a pair of channels at a time.
The four levels are +22dBu, +4dBu, 0dBu, and -10dBV. To select the proper Input Level setting, choose
the Input Level position that most closely matches the maximum output level of the audio gear being
connected to the AN-16/i v.2 rear panel TRS jacks.

As a general guideline, try the +22dB setting for the output of professional mixing consoles; use the -10dBV
setting for devices such as consumer MP3 devices and CD/DVD players.

The AN-16/i v.2 has four input level options per channel pair.
To maximize the signal-to-noise ratio when setting up your Aviom products it is important to understand
how the input and output settings on these products interact. Proper calibration and gain staging with all
devices in an audio system is essential. The AN-16/i v.2 Input Module has four input gain range settings:
+22dBu, +4dBu, 0dBu, and -10dBV, accommodating a wide range of input signal sources. Choose the
setting that allows maximum input signal level without clipping.
The AN-16/i v.2 has a maximum input level of +22dBu. Signal levels above +22dBu will clip the input stage
of the device and cause digital distortion.
The selected input gain setting on the AN-16/i v.2 front panel changes the headroom available for the input
signal, but remember that the maximum input level will always be +22dBu regardless of the selection. See
the table below.
AN-16/i v.2 Input
Level Setting Clip Point
-10dBV +4dBV
0dBu +14 dBu
+4dBu +18dBu
+22dBu +22dBu
With the input gain switch set to 0dBu, for example, input signals ranging from -∞ to +14dBu in level can
be used without clipping. A +14dBu signal level will be transmitted to all line-level output modules as a
full-code signal. Signals above +14dBu will clip the input stage of the AN-16/i v.2, and that clipped audio
data will be sent downstream to all Pro16 output modules and Personal Mixers. There are two options if
a signal level above +14dBu needs to be connected to the AN-16/i v.2 input: attenuate (lower) the output
level of the device feeding the AN-16/i v.2 channel input to eliminate clipping, or choose another input
setting. In this situation using the +4dBu setting provides more headroom, allowing a maximum signal
level of +18dBu to be used.
Check the specifications of your audio gear if you are unsure about its maximum output level. Although
you won’t harm the AN-16/i v.2 or your audio devices by using an incorrect level setting, you do want to
avoid distorting the audio that passes through the system.
