The EtherCon Connector
Pro64 Series products feature locking connectors for all network I/O. The
Neutrik® EtherCon® connector is a dual RJ45‑type connector that can receive
a standard Category 5e cable or a cable fitted with the special locking
EtherCon connector.
When using a standard Cat‑5e cable, plug the cable into the center of the
EtherCon 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 plug, the kind commonly
used on microphone cables. 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.
The 6416Y2 has two A-Net ports, labeled A and B.
2Gen e r a l in f o
Cat-5e Cables
All Cat‑5e connections between A‑Net devices should use Unshielded
Twisted Pair (UTP) cable. The cable can be of the stranded or solid type;
solid wire performs better over long distances, while stranded wire is more
flexible and easier to manipulate and therefore easier to work with in a live
performance situation.
Cables designated as Cat‑5e in Pro64 documentation can be interchanged
with any Cat‑6 (or better) cable. Cables will be referred to simply as “Cat‑5e.”
Connectors on Cat‑5e cables used with Pro64 devices can be of the standard
RJ45 variety or locking Neutrik EtherCon type.
DIP Switches
Illustrations of Pro64 DIP switch components in this document will indicate
the switch handles in black.

Cleaning
Before cleaning a Pro64 product, turn off the power switch and unplug the
unit from the AC power source.
To clean the surface of the Pro64 product use a clean, soft lint‑free cloth that
has been slightly moistened with water only. For tougher dirt, use a cloth
slightly dampened with water or with a mild detergent. Always be sure to dry
the surface of the unit before proceeding with use.
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.
Never use solvents or abrasive cleaners on the finished surfaces of your
Aviom products.

Installing the 6416Y2 Card
Before installing the 6416Y2 card in a compatible Yamaha digital device, be sure
to read the DIP switch configuration section of this User Guide (page 30).
The 6416Y2 card can be used in any MY (mini‑YGDAI) expansion slot in a
Yamaha digital mixing console or compatible digital product (see the list on
page 3). The specific number of available expansion slots varies with each
model. Yamaha expansion slots are identified by number, starting with
“Slot 1.” Within an MY expansion slot, its audio resources are referred to as
“channels,” numbered from 1 to 16 in the Yamaha interface. (The PM1D is
limited to 8‑channel operation.)
P No t e The 6416Y2 card is electrostatic‑sensitive. Before handling the card,
you should briefly touch the host unit’s metal casing with your bare
hand to drain off any static charge from your body.
The components of the card are indicated in the diagram below.

A‑Net Interface Card is done from within the Yamaha device’s user interface.
Consult the documentation that came with your Yamaha product for more
specific signal routing information.
P No t e : Always power off the Yamaha host device before removing the
6416Y2 card.
Installing Multiple 6416Y2 Cards
A Yamaha host device can support as many Pro64 A‑Net cards as it has
available MY (mini‑YGDAI) expansion slots and internal power resources.
When multiple 6416Y2 A‑Net Interface Cards are installed in a Yamaha host
device, each 6416Y2 card needs to be connected via its A‑Net ports to the
Pro64 network. Simply use a short Cat‑5e jumper cable to interconnect the
6416Y2 cards.
A list of compatible Yamaha products and the number of available MY
expansion slots on each appears on page 4.

Firmware Notice
All Pro64 devices in a network should be updated to use the most recent
rmware version to ensure trouble-free operation.
As new Pro64 modules are released, older Pro64 products need to be
updated so that they recognize the features and functions of the newer
modules—something that is especially important if one of the older devices
will be used as the network’s Control Master. (If for some reason you cannot
update the firmware on older Pro64 devices before using them, set the
newest module to be the network Control Master.)
Pro64 Update Tool is a free Windows software application for updating the
operating firmware in Pro64 Series products.
The Pro64 Update Tool requires a direct RS‑232 (serial) connection between
the computer and the Control Master device on the Pro64 network. Normally
this is accomplished by connecting a null modem DB9 cable between the
RS ‑232 jack on the computer and the Pro64 device. Complete information on
using RS‑232 (and USB‑to‑RS‑232 adapters) is available on the Aviom website.
Updates take just a few minutes per module.
Pro64 Update Tool is designed to run on a PC under Microsoft® Windows® XP.
It has also been tested and found to be compatible with Microsoft Windows
Vista®. Mac users can run Pro64 Update Tool using Windows XP running
under Apple’s Boot Camp program on Intel‑based Macs.

AC Power
The following applies to the host device that the 6416Y2 A‑Net Interface Card
is installed in.
Always plug the unit into a properly grounded (earthed) outlet. Always use
the AC line cord that was shipped with the unit. Grasp the power cable by the
connector and never by the cord itself when connecting and disconnecting
it from the power source.
Do not expose the Pro64 device to moisture, rain, or excessively damp
environments.
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).
Ventilation
Always allow adequate ventilation for devices mounted in equipment
racks. Avoid placing your Pro64 product directly above or below other rack‑
mounted devices that produce high levels of heat, such as power amplifiers.
Cleaning
Before cleaning a Pro64 product, turn off the power switch and unplug the
unit from the AC power source.
To clean the surface of the Pro64 product use a clean, soft lint‑free cloth that
has been slightly moistened with water only. For tougher dirt, use a cloth
slightly dampened with water or with a mild detergent. Always be sure to dry

About A-Net
Aviom’s A‑Net® is the only networking technology conceived, designed, and
optimized for managing and distributing audio using ordinary Cat‑5e cables.
As implemented in the Pro64® Series products, A‑Net can transmit up to 128
channels of uncompressed 24‑bit audio with the reliability and fidelity of
analog, and the power and flexibility of a true digital network.
Pro64 A‑Net allows variable sample rates in three ranges, from 44.1kHz±
to 192kHz±, with ultra‑low latency, jitter, and wander. Pro64 devices can
be connected in any combination of serial (daisy‑chain) or parallel (star)
topologies. Cable runs between Pro64 devices can be up to 400 feet (120
meters) on Cat‑5e1, and miles on single‑ or multi‑mode fiber optics (using
Aviom fiber‑capable equipment such as the M H10f ).
Because A‑Net is designed specifically for audio, the technological limitations
of Ethernet and Ethernet‑based products are removed, while audio
performance and system flexibility are increased. A‑Net incorporates Aviom’s
unique patented and patent‑pending algorithms for controlling clock jitter
and wander, as well as system‑wide latency—regardless of an installation’s
size, design, or clocking setup. A‑Net offers significant advantages in fidelity,
performance, and flexibility over Ethernet‑based products.
A‑Net uses the “physical” layer of Ethernet, but it eliminates all the protocol
elements that are designed for computers and IT‑style networking. In
audio applications, these other layers reduce efficiency, impose system
restrictions, and introduce latency and timing instability. By eliminating
Ethernet data structures, A‑Net creates a superior network, with enhanced
audio performance. With A‑Net and the Pro64 Series, Aviom continues to
break new ground in the design and development of innovative digital audio
networking technologies and solutions.
The Pro64 network offers the most flexible clocking and synchronization
options in the industry. Pro64 devices support three ranges of variable sample
rates, from 44.1/48kHz± to 192kHz±. Because no sample rate converters are
1 Cat-5e, Cat-6, or better, Unshielded Twisted Pair (UTP) cable
10ab o u t a-n et
used, audio transmission is kept fast and clean, eliminating the audio artifacts
and signal degradation inherent to sample rate conversion—even when
syncing to an external clock source.
Any Pro64 I/O module can be designated the clock master for the network,
generating and distributing its internal clock. Digital I/O modules are capable
of syncing to and distributing an external word clock.
Control Data
The Pro64 Series has built‑in, dedicated bandwidth for 14 channels of non‑
audio control data through the use of Aviom’s innovative Virtual Data Cables™
(VDC). These data streams are always available to carry MIDI, RS ‑232/RS‑422,
or GPIO (General Purpose I/O), and they never compete with the audio
channels for network resources, regardless of the system configuration.
Because VDC inputs are simply incorporated into the A‑Net stream, these
control signals can be transmitted over very long cable runs and even across
an entire Pro64 network, significantly expanding the applications possible
with MIDI, RS‑232/RS‑422, and GPIO. And as with audio signals, VDC control
data can be input anywhere and output anywhere else in the network.
The exact complement of VDC I/O connectivity varies per product.
A-Net Ports
Pro64 I/O modules have dual A‑Net ports, labeled A and B. Both ports carry
a bidirectional A‑Net stream at all times. (That is, both ports are always
transmitting and receiving A‑Net data.) Pro64 networks can be configured in
one of two operational modes, Auto Mode or Manual Mode, depending on
the requirements of a particular application.
Each A-Net port car ries bidirectional data at all times.
11ab o u t a-ne t
In Auto Mode, there are no connection rules; connect a Cat‑5e cable to either
the A or B port and the network does the rest. Auto Mode provides a true
audio network with 64 available “Slots” for transporting audio (at 44.1/48kHz).
Every audio Slot is available everywhere in the network, with no upstream/
downstream restrictions.
In Manual Mode, the Pro64 network becomes a 64x64 system (at 48kHz),
similar to a traditional stage‑to‑FOH snake. At every point in the Manual
Mode network, two 64‑channel streams are available on the cable and in
each module. The configuration of the cables and ports has an impact on the
makeup of the network and the distribution of audio signals. The user can
direct A‑Net data from a Pro64 input module to a specific port (A, B, or both).
Likewise, Pro64 output modules can be configured to output audio signals
received from a specific Pro64 network port (A or B).
Support For Pro16 Series Products
Pro64 Series products can be combined with Pro16® Series output products
such as the Pro16 Monitor Mixing System by adding the Pro64 ASI A‑Net
Systems Interface. This 1U module converts Pro64 data to Pro16 data,
providing up to four 16‑channel streams of data (depending on the Pro64
sample rate) that can be used with A‑16II and A‑16R Personal Mixers, A‑Net
Distributors, and AN‑16/o Output Modules.
The ASI is not compatible with the A‑Net output of Pro16 input modules such
as the AN‑16/i and AN‑16/i‑M and console interface cards such as the Y1.

Pro64 User Interface
This section outlines some basic concepts of operation for Pro64 products.
Pro64 I/O devices have some common user interface elements that make
setting up an audio network easy to understand. Although the 6416Y2 is
set up using DIP switches, its interface elements are similar to other Pro64
hardware I/O modules that use buttons and LEDs for comparable features
(seen in some of the examples). Any combination of Pro64 devices can be
used when setting up a Pro64 network.
A-Net Slot
Pro64 I/O devices come in a variety of configurations. To allow a large
number of hardware audio input devices to be available to the Pro64 audio
network, Aviom has implemented the concept of the A‑Net Slot to simplify
the configuration of potentially complex audio networks. Simply put, an
A‑Net Slot is a place in the network where an audio input resource (analog or
digital) is assigned.
A Pro64 network will always have a finite number of A‑Net Slots available
that can be addressed by an unlimited number of hardware channels. The
actual number of available Slots is determined by the current sample rate.
Slots versus Channels
You might be wondering why Aviom chose to refer to the audio I/O resources
in the Pro64 Series products as ‘’Slots.” Why not just call them “channels”?
We did this to avoid confusion between references to physical hardware
audio resources and virtual network audio resources. The word ‘’channel’’ is
ambiguous and may cause confusion when configuring an audio network.
“Channel” appears in many contexts, including audio mixing consoles, mic
preamps, DSP processors, and DAW software.
We use the word ‘’channel’’ when referring to the physical audio inputs—
analog or digital—on a piece of hardware (such as the 16 line‑level XLR
input jacks on the 6416i Input Module or a Yamaha console resource such
as a direct output or aux bus send). Each of these audio input sources can
be made active and added to the network individually, and it is only when
activated that they use any network resources (the A‑Net Slots). To allow
this functionality, Pro64 products separate the hardware resources from the
available network resources by giving each hardware input channel a switch
or button that allows it to be added to the network as needed. (The 6416Y2
card uses DIP switches.)
It is these activated hardware resources that are being referred to as “Slots.”
13Pr o 64 u se r i n t e r f a C e
Pro64 audio networks can potentially have a greater number of audio
channels and hardware I/O devices connected than the network can make
use of at one time. This provides flexibility without requiring constant re‑
patching.
Keep in mind that a Pro64 A‑Net network can only manage a specific number
of Slots at a time, and this number varies with the sample rate being used.
The maximums are 64 Slots in Auto Mode at the 48kHz sampling rate and
64x64 Slots in Manual Mode at 48kHz.
In summary, think of “channels” as hardware resources that can be added to
the network as needed and “Slots” as locations within the Pro64 digital audio
network pipeline that A‑Net uses to move data throughout the network.
Slots and Sample Rate
The current system‑wide sample rate will determine the number of A‑Net
Slots that are available. Auto Mode and Manual Mode have the same number
of Slots at each sample rate; only the direction of the data is different.
Sample Rate A-Net Slots Yamaha Compatibility
4 4.1kH z64Yes
48kHz64Yes
88.2kHz32Ye s
96kHz32Ye s
176.4kHz16No
192kHz16No
Even though the network sample rate may change the available number of
A‑Net Slots, the I/O capacity of a hardware device does not change. That is, a
16‑channel input module in a 96kHz network can still have all of its channels
activated; all of its physical inputs can operate at 96kHz.
The current sample rate will also affect the display of available A‑Net Slot
ranges. Slot ranges will always have the same maximum number as seen
in the sample rate chart. At 96kHz, for example, only Slots 1 through 32 are
available; the Slot range from 33 to 64 is inactive and unavailable at 96kHz.
Slot ranges outside the maximum for the current sample rate can be selected,
but attempting to activate a channel in an unavailable range will result in an
error message on hardware I/O modules (the selected channel button, A‑Net
Slot range, and sample rate LEDs will all flash). Note that console interfaces
such as the 6416Y2 card have no A‑Net Slot displays and cannot display these
error messages.

A-Net Base Slot
Since the capacity of the Pro64 network could be as high as 64 A‑Net Slots,
Pro64 hardware I/O devices need a way of routing a selected hardware
channel to a desired network Slot. The 6416Y2 uses DIP switch block SW9
to select a base Slot range, in groups of 16 channels. There is no Slot display.
See page 39 for more info on A‑Net Slot setup.
For Pro64 hardware I/O devices, the upper left corner of the front panel
contains a dedicated A‑Net Slot display. Its associated inc/dec buttons are
used to select a range of Slots that the hardware device will address.
The A-Net Slot display and its inc/dec buttons are used to set the base Slot
for a Pro64 I/O module. An input module is shown here.
The following table shows the channel‑to‑Slot correlation for 16‑channel
Pro64 Series modules in a network running at the 48kHz sample rate. The
numbers in the Base Slot column will appear in the A‑Net Slot display of all
I/O modules (the 6416Y2 has no Slot display).

The use of Slot assignments allows for easy reconfiguration of audio
networks and sharing of hardware I/O resources and data without physical
re‑patching.

A-Net Slot Example
The following example shows the power of the Pro64 network and the A‑Net
Slots concept.
The range of A‑Net Slots used in the example has been limited to the group
from 1 to 16 for simplicity.
This graphic represents a Pro64 product set to use Slot range 1.

One 16‑channel input module is placed in each of four rooms of a production
facility, designated as Studios A, B, C, and D. One 16‑channel output module
is installed in the facility’s Studio E. All modules are set to Slot range 1 (shown
in grey).

By activating a few channels on each of the four input modules, a total of
sixteen inputs (Slots) are used, indicated by reverse text. All of these inputs
are available throughout the Pro64 network at every output module—
analog, digital, Yamaha card, etc. The operator in Studio E can use the sixteen
sources from Studios A, B, C, and D simultaneously.
The order in which the Pro64 devices are connected is irrelevant.

Network Modes
A Pro64 audio network can be set to operate in one of two modes, Auto or
Manual. The network mode can be selected on the front panel of the I/O device
designated as the system’s Control Master or from the DIP switches in block SW9
if the 6416Y2 card is set to be the Control Master. See page 39 for more info on
A‑Net Slot setup.
Both modes are fully bidirectional at all times, regardless of the system layout or
design.
Auto Mode
Pro64’s Auto Mode takes most of the work out of managing resources in an
audio network. This is the “everything everywhere” mode. Input channels
made active in the network can be seen and used by all devices in the
network, regardless of how the modules are connected and regardless of
the physical location of any module. Output modules do not need to follow
input modules as in a traditional analog system. In Auto Mode, both A‑Net
ports (A and B) function identically.
Once configured for Auto Mode, the system ensures that only one hardware
input channel is activated into a given A‑Net Slot. There is no limit to the
number of output channels that can use a given A‑Net Slot—unlimited
digital splits. The actual number of available Slots is determined by the
current sample rate. The maximum number of available Slots (active input
channels) is 64 at the 44.1/48kHz sample rate.

P No t e : Sample rates above 96kHz are not compatible with Yamaha
devices.

in Auto Mode
Manual Mode
When more than 64 channels are needed in a network or digital snake,
Manual Mode can be used to provide configurations of up to 64x64 channels.
Two unique 64‑channel streams are available at each module. In Manual
Mode, the A and B A‑Net port connections can be used to direct and route
A‑Net data.
Pro64 input modules can send their audio inputs to either or both A‑Net
ports, while output modules can listen to data from either port. For a
traditional stage‑to‑FOH snake system, this allows the user to configure a
18Pr o 64 us e r in t e r f a C e
system with up to 64 sends from the stage and another unique stream of up
to 64 returns to the stage.
Manual Mode operation removes the restrictions of unique channel‑to‑Slot‑
range relationships found in Auto Mode. Slots can be overwritten, allowing
the user to replace channels from one part of the network with new data. This
means that, while no more than 128 total Slots can be active in the network
at a particular location, there is no practical limit to the total number of audio
channels in the system.
The number of available Slots in Manual Mode is dependent upon the current
sample rate.

In every Pro64 network, one device will always be designated as the Control
Master, the device that manages all A‑Net resources for the network. The
Control Master can be any I/O module in the network, and can be assigned or
changed by the user as needed. Only one device can be assigned as Control
Master in a Pro64 network at a time; an A‑Net Pro64 network cannot function
without a Control Master.
The functions of the Control Master include:
System resource and information management •
Setting •network mode (Auto or Manual)
Management of •active channels (Slots) in Auto Mode
System‑level command and control functions •
Keeping track of all Pro64 devices in the network (by type •
and quantity)
Control of the current system‑wide •sample rate
• Clock Master (analog modules only)
System lock via •password on/off
Management of •Virtual Data Cable (VDC) resources
Management of •stereo link status
Requests to enter Managed Mode •
The Control Master status is identified with a red LED on the front panel of
the device currently assigned as the Control Master. Depending on the type
of device (rack‑mounted I/O module or console interface card), the method
used for designating Control Master status may be different.
The Control Master LED is labeled CTL on the 6416Y2 card.
