Welcome

Thank you for purchasing the 6 416Y2 A-Net® Interface Card for use with
Yamaha® digital products that support the mini‑YGDAI (MY) card format. This
User Guide is designed to familiarize you with the features and functions of
your new Pro64® product. All Pro64 products are powered by A‑Net®, Aviom’s
proprietary data transmission protocol designed especially for the unique
demands of live streaming audio.

In developing the Pro64 Series, we have made every effort to make the user
interface as easy to use and understand as possible. We encourage you to
read the manual completely, as some of the powerful features of your new
product may not be immediately apparent.

Package Contents

Check the contents of the shipping box carefully before making connections
and continuing with installation.

The contents of the 6416Y2 A‑Net Interface Card box includes:

One 6416Y2 A‑Net Interface Card •
User documentation •

P No t e Retain the protective bag that encloses the 6416Y2 card. The card is

static‑sensitive. Use the bag whenever the card will be transported
without being installed in a Yamaha device.

Features

The 6416Y2 A‑Net Interface Card is a 16‑channel Pro64 A‑Net I/O expansion
card for Yamaha’s digital devices including digital mixing consoles and
the Digital Mix Engine™ (DME) products. It provides a host of professional
features designed to make audio networking with Pro64 Series products
easy to set up and configure in a variety of professional audio situations.

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.

In this diagram, all DIP switches are in the down position.

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.

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,

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.

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

8main ta i ni n G Yo u r Pr o 64 Pr o d u C t

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.

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.

Pro64 Series Supported Sample Rates

Sample Rate Minimum Maximum

1x 44.1/48kHz 39.7kHz 52kHz
2x 88.2/96kHz 79.4k Hz 104 kHz
4x 176.4/192kHz 158 .8 kH z 208kHz

Clocking

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 z 64 Yes
48kHz 64 Yes

88.2kHz 32 Ye s
96kHz 32 Ye s

176.4kHz 16 No
192kHz 16 No

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.

14Pr o 64 us e r in t e r f a C e

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).

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.

Available A-Net Slots
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.

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:

This section describes the individual functions of the Control Master device
in a Pro64 network.

Enumeration

When the Control Master is powered on, its first job is to identify and count
all connected A‑Net modules in the network in a process called enumeration.
The time for this process will vary based upon the number of Pro64 modules
in a system. This process cannot begin until the host Yamaha device has
finished its own power‑up cycle when a 6416Y2 A‑Net Interface Card is the
Control Master.

Enumeration is an automated process performed by the command and
control portion of the A‑Net software. There are no user‑controllable
functions or settings.

During the enumeration process, all connected A‑Net modules will flash their
blue A‑Net LEDs, indicating that a request to be added to the Pro64 network
is being made. Once granted entry by the Control Master, the individual
module’s blue A‑Net LED will light solid to indicate that it is now receiving
valid A‑Net packets and is part of the Pro64 network.

The blue LED is used to indicate ne twork status.

If valid A‑Net packets are not received, the module will reset and wait until a
valid A‑Net stream is detected.

During enumeration, any conflicts will also be resolved. For example, consider
a new Auto Mode installation using eight input modules set to the same
A‑Net Slot range with all channels activated during a bench configuration.
When all these input modules are connected and then powered up, only
one of them will be allowed to have all 16 channels activated. The remaining
seven modules will have their audio channels deactivated. Conflicts with
channel activation on 6416Y2 cards must be resolved manually since Slot
activation is controlled via DIP switches.

When a new device is added to an existing Pro64 network, the new device
makes a request to the Control Master for inclusion in the network. During
this time, the new module’s blue A‑Net LED will flash. When the new module
has been enumerated by the Control Master, its blue A‑Net LED will then light
solidly to indicate that the Control Master has granted the module access to
the network. Adding a new module will interrupt network operation briefly.

Control Master and Clock Source

The Pro64 device designated as Control Master is also in control of the
network master clock. The front‑panel Clock Master LED lights to indicate
that a module is designated as the network’s master clock source. (The
6416dio Digital I/O Module is the only exception to this rule.)

The red Clock Master (CLK) LED lights when a Pro 64 device is the Control
Master.

When an analog I/O module is the Control Master, no other analog module
can be used as a clock source in an all‑analog network. When a 6416Y2
console interface card is part of a Pro64 network, the 6416Y2 can be used
as a Clock Master for the network, but it must also be the network’s Control
Master to do so.

When using a 6416Y2 card as the Clock Master, the clock is derived from the

23Co n t r o l ma s t e r

Yamaha host device and shared throughout the Pro64 network. That clock
reference can be the Yamaha host’s internal clock or an external clock to
which the Yamaha host device is synced. Changes to the host device’s sample
rate will affect available A‑Net Slots.

Multiple 6416Y2 cards can be used in a Yamaha host device, but only one can
be set to be Control Master, which automatically makes this card the Clock
Master.

Other Clock Sources

External clock sources for the Pro64 network can include:

The internal clock from the Yamaha device •
Word Clock received via the external Word Clock inputs on •

a Yamaha device

• Word Clock connected to the dedicated BNC Word Clock
jack on a Pro64 digital I/O device, such as the 6416dio
Digital I/O Module

• The AES3 (AES/EBU) clock signal embedded in an AES3
digital signal connected to a Pro64 digital I/O module such
as the 6416dio

Clock Errors

If a clock error occurs, the Clock Master LED will blink indicating that an error
has occurred. Common causes for a clock error include:

Attempting to change the sample rate on a device other •
than the Clock Master

Attempting to change the clock source when the network •
is password protected

Removing or changing external clock sources on a digital •
I/O module

Incorrect configuration of an external clock source on a •
digital I/O module

Attempting to use a sample rate higher than 96kHz with •
the 6416Y2 card

Network Sample Rate

When an analog device is the Control Master, the Control Master device is
automatically designated as the network Clock Master. It will remain the
Clock Master until a different analog module is made the Control Master or
until a digital module such as the 6416Y2 card is added to the network and is
assigned to be the Control Master and Clock Master.

24Co n t r o l m as t e r

The network’s internal master clock is derived from the sample rate currently
in use. The sample rate also affects the total number of available A‑Net Slots
available for use in the Pro64 network.

The Clock Master LED on the 6416Y2 card (labeled CLK) will light automatically
when its Yamaha host is powered on if the 6416Y2 card is Control Master and
Clock Master for the Pro64 network.

The Sample Rate section of a rack‑mounted hardware I/O module’s front‑
panel interface (e.g., 6416i Input Module) includes a group of LED indicators
for displaying the current network sample rate. One LED will be lit at all
times. The 6416Y2 card has no such LEDs. However, the current sample rate
information will be sent to all Pro64 network devices when a 6416Y2 card is
Control Master/Clock Master.

The sample rate display on Pro6 4 I/O modules will
display the current network-wide sample rate when
a 6416Y2 A-Net Interf ace Card is the Clock Master,
receiving its clock f rom the Yamaha host device.

The current sample rate for the network will be displayed on all I/O modules
in the network, and will update to reflect any changes made from the Yamaha
host (such as changing the sample rate from 44.1kHz to 48kHz, or from 48kHz
to 96kHz). Only one sample rate can be used at a time in a Pro64 network.

P No t e : If multiple Yamaha devices with 6416Y2 cards installed are used

in a Pro64 network, only one 6416Y2 card can be set as the Pro64
network Control Master. Each additional Yamaha device must be a
clock slave in this situation.

Changing the Sample Rate

Changing the sample rate when a 6416Y2 A‑Net Interface Card is the Clock
Master is done from within the Yamaha user interface. Changing the sample
rate will affect the number of available A‑Net Slots when the sample rate
changes from the 1x range (44.1/48kHz), to the 2x range (88.2/96kHz), or vice
versa. Note that only sample rates up to 96kHz are supported by Yamaha
digital devices.

25Co n t r o l ma s t e r

Auto/Manual Mode Selection

The Control Master can be used to set the current network mode to Auto or
Manual. As with the system‑wide sample rate, the network mode is also a
global setting. Only one Pro64 device can be Control Master in a network.
Changes to the network mode must be made from the Control Master.

The 6416Y2 is configured using DIP switches, with DIP Switch Block 9 (SW9)
on the circuit board used to set the network mode. This means that changes
to the Pro64 network mode require the host Yamaha device to be powered
down so that the 6416Y2 card can be safely removed.

Changing the Network Mode

To change the network mode from a 6416Y2 card that is the Pro64 network’s
Control Master, first power down the Yamaha host device and then remove
the 6416Y2 card. Move switch 1 in Switch Block SW9 to the desired position,
down for Auto Mode, or up for Manual Mode. Reinstall the card and power
up the console. The Control Master will update the display on all modules in
the network to reflect the mode change once the network is restarted.

Managed Mode

Managed Mode requires the use of a computer with the Pro64 network for
tasks such as firmware updates, system monitoring, control, and editing.
The Control Master is the only module that can allow the network to enter
Managed Mode.

Entering Managed Mode from a 6416Y2 card requires that the 6416Y2 card
be the network’s Control Master. DIP Switch Block 9 (SW9) is used to set the
network for Managed Mode operation. This means that changes to the Pro64
network mode require the host Yamaha device to be powered down so that
the 6416Y2 card can be removed.

To change the network mode from a 6416Y2 card that is the network Control
Master, move switch 10 in SW9 to the up position Once the network enters
Managed Mode, all rack‑mount I/O modules will light their Managed LEDs.
Note that the 6416Y2 does not have a Managed Mode LED.

To manage a Pro64 network with a computer, the PC needs to be connected
to the Control Master using a DB9 null modem cable connected to the RS‑2 32
port. The 6416Y2 card must be set for RS‑232 operation and not for RS‑422;
this is done from DIP Switch Block 4 (SW4) on the circuit board. See page 32
for more information.

Exiting Managed Mode also requires that the host Yamaha device be
powered down so that the 6416Y2 card can be removed to have DIP switch
settings changed.

A Pro64 network can be password protected from the Control Master only.
Once protected, the front‑panel interface on all modules is locked, preventing
changes to A‑Net Slots, sample rate, clock source, channel activation, stereo
links, and Virtual Data Cable assignments. Hardware switches, such as gain
settings on input and output modules, and rear‑panel DIP switches are in the
analog domain and are not affected. Password protection remains in force
even when a system is power cycled.

All Pro64 hardware I/O devices except console interface cards ship with a
default password. The 6416Y2 card can be used to lock the network, but no
password is available.

To lock the Pro64 network, move switch 9 in the front‑panel DIP switch block
to the down position. Changes to the network lock status will be instantly
reflected on other network modules. No edits are possible until the network
is unlocked. When the 6416Y2 card is Control Master, simply move switch 9
in the front‑panel DIP switch block to the up position to unlock the network
and allow changes to be made.

DIP Switch 9 on the front panel can be used to loc k the Pro64 network when
in the down posi tion.

Front Panel Features

This section describes the features and functions of the front panel of the
6416Y2 A‑Net card interface.

Thumb Screws

The two permanently attached thumb screws on the 6416Y2 card are used to
secure the card to an MY expansion slot in the Yamaha device. Always make
sure that both thumb screws are firmly attached when using or transporting
the Yamaha device with a 6416Y2 installed.

RS-232/422 Port

The nine‑pin DB9 RS‑232/422 port can be configured to send/receive control
data from the Yamaha interface or from the Pro64 Virtual Data Cables.
Selection of RS‑232 or RS‑422 and baud rate configuration is done via the DIP
switches on the circuit board of the 6416Y2 card.

Each type of control data communication—RS‑232 and RS‑422—requires a
unique cable. RS‑232 requires a null modem cable; RS‑422 requires a straight‑

DIP Switches

There is one 12‑position DIP switch block on the front panel of the 6416Y2,
referred to as SW7 in the diagrams that follow. Note the mounting direction
of the DIP switches; to activate a switch on SW7, move it to the down position.
The default setting for all switches in this block is up.

In this diagram, channels 7-8, 13-14, and 15-16 are stereo linked. This 6416Y2
is also the net work Control Master. DIP switch handles are indicated in black.

Clock and Control DIP Switches

Within front panel DIP Switch Block SW7 is a group of four system‑level DIP
switches. These control the system lock via password, 6416m preamp remote
control via m‑control, firmware update status, and Control Master vs. Slave
status respectively.

Switch Function Off (up) Function On (down)

Stereo Link DIP Switches

Eight Stereo Link DIP switches are provided allowing odd‑even channels to
be paired for use with Aviom Pro16 personal monitoring products such as
the A‑16II and A‑16R Personal Mixers. (This application requires the ASI A‑Net
Systems Interface.) Each DIP switch controls a pair of channels. Stereo Link
information will be passed to all Pro64 modules. If applicable, a Stereo Link
LED will light on Pro64 output modules such as the analog 6416o Output
Module and 6416dio Digital I/O Module when stereo information is present
in the network.

System Lock

When the 6416Y2 card is the Pro64 network Control Master, DIP switch 9
controls the Password Lock feature, allowing all devices in the network to be
locked from a single location. Unlike Pro64 hardware I/O devices, there is no
way to set a password code on the 6416Y2 card. The Pro64 network is locked/
unlocked immediately when the DIP switch is moved. No edits are possible
when the network is locked.

m-control

Use DIP switch 10 on the front panel to activate the m‑control™ for Yamaha
Digital Consoles feature, allowing remote control of 6416m Mic Input Module
preamp settings such as gain, phantom power, and low cut filter directly
from the Yamaha user interface.

Local Code Update

The Local Code Update DIP switch is used in conjunction with the Pro64
firmware update application. This switch is scanned only when the host
Yamaha device is powered up. Changing the position of this DIP switch
requires a reboot of the host device for the switch position to be recognized.

Control Master/Slave

DIP switch 12 is used to set the 6416Y2 card as either the network Control
Master (down) or as a slave device (up). Note that only one Pro64 device
can be Control Master in a network. Although this DIP switch setting can be
changed on the fly, note that the Pro64 network will need to reset if a new
Control Master device is selected. Audio and control data are interrupted
while the network resets.

Two Pro64 A‑Net ports are provided on the 6416Y2 card, labeled A and B.
Each port has a Neutrik® EtherCon® connector and can support standard
RJ45 cables or those fitted with the heavy‑duty EtherCon plug.

Multiple 6416Y2 cards can be used in compatible Yamaha devices by linking
them together via the A‑Net ports with a short Cat‑5e jumper cable.

Front Panel LEDs

A set of five LEDs on the front panel of the 6416Y2 card is used to inform the
user of various network conditions and/or error states as described below.

Auto LED

The Auto LED will be on and lit yellow to indicate that the Pro64 network is
running in Auto Mode. In the off state, this LED indicates that the network is
operating in Manual or Managed Mode.

Control Master (CTL) LED

The yellow Control Master (CTL) LED indicates that the 6416Y2 card is set to be
the network’s Control Master. A 6416Y2 card set to be the network’s Control
Master is automatically set to be the network Clock Master as well, deriving
the network clock from the Yamaha host device. Only one Pro64 device can
be set to be the Control Master, regardless of the number of 6416Y2 cards
installed.

When off, this LED state indicates that the card is a slave device. For more info
about the Control Master, see page 17.

Here, DIP switch 12 is in the down position, making this 6 416Y2 card the
Pro64 net work Control Master. When DIP switch 12 is in the down position,
both the Control Master (CTL) and Clock Master (CLK) LEDs will be lit. This
6416Y2 card is also the Clo ck Master when it is set to be the Control Mas ter.
(DIP switch handles are shown in black.)

31Ca r d Co m P o n e n t s

Clock (CLK) LED

The Clock (CLK) LED will light yellow when the 6416Y2 card is set to be the
Pro64 network’s Control Master, which automatically sets the card to be the
network Clock Master. When the 6416Y2 card functions as the network Clock
Master, its clock is derived from the Yamaha host device.

Only one Clock Master is possible in a Pro64 network. The Clock LED will
remain unlit when the 6416Y2 card is a slave device to another clock source
(either the Pro64 network internal clock or from an external Word Clock
reference connected to a Pro64 digital I/O module such as the 6 416d io) .

Error (ERR) LED

The Error LED will light red to indicate errors in enumeration, configuration,
or clocking.

A-Net LED

Whenever a valid A‑Net connection is detected, the blue A‑Net LED will light
solid. The A‑Net LED will flash during the network enumeration process as
Pro64 devices are added to the network, or during a firmware update. If no
valid Pro64 A‑Net signal is detected, the A‑Net LED remains off.

Circuit Board DIP Switches

The 6416Y2 A‑Net Interface Card is configured using DIP switches. Each
block of switches is labeled on the circuit board with the abbreviation “SW”
followed by a number. There is one DIP switch block on the front face of the
card (SW7), and there are six DIP switch blocks on the card’s circuit board.
These will be hidden once the card is installed.

The following table lists the functions of the various DIP switch blocks on
the 6416Y2. Note the locations of the various switches on the diagram that

DIP Switch Functions

The individual switch functions for circuit board DIP switch blocks SW1, SW2,
SW3, SW4, SW8, and SW9 are detailed in this section.

DIP Switch Block 1 (SW1)

Use Switch Block 1 (SW1) to activate channels 1‑8 on the 6416Y2 card and
assign them to Slots within the Pro64 network. In the down position, channels
1‑8 are off; move a DIP switch to the up position to activate a channel and
assign it to a Slot in the Pro64 network.

The default position for the SW1 DIP switches is down (channel‑to‑Slot
activation is off).

P No t e : Signals from the Yamaha device cannot be routed into the Pro64

network unless these DIP switches are activated.

DIP Switch Block 2 (SW2)

Switch Block 2 (SW2) is used to assign channels 9‑16 on the 6416Y2 card to
Slots in the Pro64 network when operating in MY16 Mode (channels 9‑16 are
not available in MY8 Mode). In the down position, channels 9‑16 are off; move
a DIP switch to the up position to activate a channel, which assigns it to a Slot
and makes it available throughout the network.

P No t e : Routing an audio resource from within the Yamaha user interface

to the 6416Y2 installed in an expansion slot requires that the SW1
and SW2 Slot activation DIP switch settings be set correctly in order
to pass digital information from the Yamaha device to the Pro64
network.

The exact Pro64 Slot range to which the channels from the 6416Y2 card are
routed is determined by the settings of DIP switches 5 and 6 on block SW9.

The default position for the SW2 switches is down (channel‑to‑Slot activation
is off). When operating in MY8 mode, leaving these switches in the down
position will help avoid potential Slot availability conflicts with other Pro64
devices in the network.

A blank DIP switch template is provided at the end of this User Guide to allow
you to record and save 6416Y2 card settings.

MY8 and MY16 Mode Operation

Yamaha digital products can operate in either 8‑channel or 16‑channel
modes (called MY8 and MY16 respectively). MY8 Mode allows eight channels
of I/O per expansion card at sample rates up to 96kHz. MY16 Mode operation
allows up to 16 channels per expansion card at the 44.1/48kHz sample rate.
The 6416Y2 can be set to accommodate these modes by setting DIP switch

10.

Managed Mode

Switch 10 in Switch Block SW9 sets the Pro64 network to operate in Managed
Mode. This switch only functions when the 6416Y2 card is set to be the
network’s Control Master. Remember that even in a network where multiple
Yamaha devices with 6416Y2 cards installed exist, only one 6416Y2 card can
be set as the Control Master.

Managed Mode is used when updating firmware or whenever a computer is
in control of a Pro64 network.

CTLCLKAUTO ERR

The first step in setting up a Pro64 network is to decide which Pro64 device
will be the Control Master. A Pro64 network always has one Control Master
and one Clock Master. The Control Master is in charge of network‑wide
settings, channel/Slot management, Virtual Data Cable allocation, error
messaging, etc. The Clock Master controls the network sample rate and can
allow the use of external word clock sources if 6416dio Digital I/O Modules
are part of the network. Any I/O device can be the Control Master, but only
one Pro64 device may be in control of the network at a time.

6416Y2 as Control Master

On the front panel of the 6416Y2 card, DIP switch #12 is used to set the card
as the network’s Control Master—move it to the down position to make
the 6416Y2 card the network’s Control Master. When the 6416Y2 card is the
Control Master, it is also automatically the network Clock Master, deriving the
clock from the Yamaha host device.

This card is se t to be the Control Master; DIP s witch #12 is in the down
position. (The DIP switch handles are shown in black.)

Pro64 I/O Modules as Control Master

To use another type of Pro64 module as the Control Master, such as a 6 416m
Mic Input Module, set the appropriate DIP switch on its rear panel to make
it the Control Master. Make sure to set the 6416Y2 card for non‑control
operation (DIP switch #12 up) if it was previously used as the Control Master.

When an external Pro64 I/O module is used as the Control Master, all Yamaha
digital consoles and DME in the system must be set to slave to the incoming
clock from the Pro64 network. This is done of the DIO or Word Clock page
depending on the console being used.

Failing to set the Yamaha device(s) to slave to the incoming Pro64
network clock will cause clicks, pops, and/or audio dropouts.

Every Pro64 network has three operational modes. Auto Mode allows 64
active total channels at 48kHz, while Manual Mode provides 64x64 channels.
Managed Mode requires a computer for control, and is used for firmware
updates, etc.

The network mode is set on switch block SW9, and is only required to be set
when a 6416Y2 card is used as a Control Master. DIP switch #1 in block SW9
selects Auto Mode in the down position or Manual Mode in the up position.

The rst DIP s witch in block SW9 sets the network to Auto Mode when in the
down position.

Auto Mode provides 64 total channels/Slots at 44.1 or 48kHz, and 32 total
channels/Slots at 88.2 or 96kHz. Cables can be connected to any available
A‑Net port.

Manual Mode provides 64x64 total channels/Slots at 44.1 or 48kHz, and
32x32 total channels/Slots at 88.2 or 96kHz. The user must connect cables
to specific A‑Net ports and route data to/from them as required by the
application. Manual Mode is ideal for high channel count systems that have

48Co n f i G u r i n G t h e 6416Y2 Ca r d

clearly defined directional needs such as a 64 x 16 digital snake.

Although the Pro64 network can operate at sample rates higher than 96kHz,
Yamaha devices cannot. The Pro64 176.4 and 192kHz sample rates are not
available when using a 6416Y2 card in a Pro64 network.

MY8 and MY16 Modes

Switch block SW8 contains the setting for Yamaha’s MY8 and MY16 Modes.
MY16 Mode provides 16‑channel operation at 44.1/48kHz sample rates, while
the MY8 Mode provides 8‑channel operation when using higher sample rates
(88.2/96kHz) or when installing the 6416Y2 card in MY8‑only devices such as
the PM1D digital console at 48kHz.

Set DIP switch #10 in block SW8 to the up position (as seen in the diagram
above) for 16‑channel operation at 44.1/48kHz.

Use switch block SW9 to set the range of Slots (in blocks of 16 channels) that
each 6416Y2 card will use when transmitting/receiving audio.

DIP switches #7 and #8 are used for the receive Slot range, in groups of 16
channels (1‑16, 17‑32, 33‑48, or 49‑64). These are the channels from the Pro64
network being brought into the Yamaha device for mixing, processing, etc.

DIP switches #5 and #6 are used to select the network transmit Slot range
(available settings are 1‑16, 17‑32, 33‑48, or 49‑64). Use these for audio being
sent from the Yamaha device into the Pro64 network. Each Slot can be
activated individually using SW1 and SW2 (see below).

Block SW9 is use d to choose A-Net Slot transmit (Tx) and receive (Rx)
settings. The 6416Y2 card shown here receives Slots 1-16 and transmits Slots
49-64 into the network.

50Co n f i G u r i n G t h e 6416Y2 Ca r d

Remember that the 6416Y2 card functions as both an input and an output
module. Set different Pro64 network transmit/receive (Tx /Rx) Slot ranges to
avoid channel/Slot allocation conflicts. This is especially important in multi‑
card systems.

Activate Channels/Slots

Once the Transmit base Slot range has been selected, use DIP switch blocks
SW1 and SW2 to activate up to 16 individual Slots in that range, which sends
audio from the Yamaha console (or DME) into the Pro64 network. No audio
will flow from the Yamaha device into the Pro64 network unless the Slots are
activated with these switches.

Move a DIP switch to the up (on) position to activate it, sending audio into
the Pro64 network. Remember that in Auto Mode there can be only one
channel assigned to each network Slot.

Individual channel/Slot activation allows the most flexibility; activate only
the channels/Slots you need on each 6416Y2 card, leaving network Slot
bandwidth available for other Pro64 devices in your network. A Pro64
network is capable of having a virtually unlimited number of devices in it.
While the number of devices is unlimited, the bandwidth of the network
itself is not.

Digital splits and copies of data within the Pro64 network are not subject to
the 64 Slot maximum (at 44.1/48kHz); an unlimited number of copies of the
same data can be used in both analog and digital formats as needed.

In most cases, you’ll want the 6416Y2 card to run in Yamaha’s MY16 Mode,
which provides 16 channels in and out of the MY expansion slot at 48kHz.
(This is set on switch block SW8 using DIP switch #10.)

into the Pro64 network Slots, simply change the appropriate DIP switches in
blocks SW1 and/or SW2. For example, to transmit only 8 total channels from
the Yamaha console to the Pro64 network, move all DIP switches in block
SW2 to the down position. Those Slots are then available to be used by other
Pro64 input devices within the network.

The second card in the 48 x 16 digital snake receives Slots 17‑32 from the
network. It has the same Transmit Slot settings as card #1, but note that all 16
activation switches in blocks SW1 and SW2 are in the off (down) position.

The second 6 416Y2 card in the 48 x 16 digital snake receive s Slots 17-32 and
transmits nothing into the network .

Since the Transmit Slot range in SW9 is set to Slots 49‑64 but has no active
channels (as seen in SW1 and SW2) this parameter could be set to any other
range with no impact on the digital snake’s operation.

As with card #2 of this digital snake, since the Transmit Slot range in SW9 is
set to Slot range 49‑64 but has no active channels (as seen in SW1 and SW2)
this parameter could be set to any other range with no impact on the digital
snake’s operation.

Install the Cards

Install 6416Y2 card #1 into Yamaha MY expansion slot #1, 6416Y2 card #2
into MY expansion slot #2, etc., to simplify patching and routing from within
the Yamaha user interface. Connect the 6416Y2 cards together with Cat‑5e
jumper cables.

If you are using the ASI A‑Net Systems Interface to connect a monitoring
system, connect the monitoring devices to the outputs marked 49‑64 on the

54Co n f i G u r i n G t h e 6416Y2 Ca r d

rear panel of the ASI.

To create digital splits of the source signals in the network, simply connect
Pro64 output devices such as the 6416o Output Module for analog outputs,
the 6416dio for AES3 digital outputs, or even additional Yamaha digital
consoles with 6416Y2 cards installed.

32 x 16 Digital Snake

To create a 32 x 16 digital snake you can use the diagrams given previously for
the 48 x 16 snake. Delete 6416Y2 card #3 from the setup, leaving the Transmit
and Receive Slot range settings on cards 1 and 2 the same.

Remote Control

If 6416m Mic Input Modules are installed as part of the digital snake you have
the option of remote controlling the 6416m preamps from the network using
the RCI Remote Control Interface and MCS Mic Control Surface or from the
Yamaha console using m‑control.

55Co n f i G u r i n G t h e 6 416Y2 Ca r d

m-control

With m‑control™ for Yamaha digital consoles, the 6416m Mic Input Module
can be remote controlled directly from a Yamaha console’s user interface
when a 6416Y2 A‑Net Interface Card is installed. Using m‑control, an engineer
has direct access to the 6416m preamp’s gain control, +48V phantom power,
and high pass (low cut) filter. Up to 64 channels of 6416m mic preamps can be
controlled from a Yamaha console. Systems may utilize multiple simultaneous
control points: multiple consoles, multiple RCI/MCS combinations, or any
combination of the two.

Remote mic preamp control is not supported by every Yamaha console, and
the actual number of remote controllable channels varies by console model.
All existing 6416Y2 cards as well as 6416m and RCI modules in the field can
be updated to take advantage of the remote control features.

Since using the Pro64 m‑control feature requires the use of the RS‑422
resources of the Yamaha console, simultaneously controlling Pro64 6416m
mic preamps with m‑control and Yamaha AD8HR preamps via the Virtual
Data Cables™ (VDC) is not supported.

Yamaha Hardware Requirements

The following Yamaha devices can be used to send remote control commands
to 6416m preamps via m‑control:

•LS9‑16 •DM1000

•LS9-32 •DM2000

•M7CL‑32 and M7CL‑48 •DME24N

•PM5D / PM5D‑RH •DME64N

Console based remote control of the 6416m is not compatible with the PM1D,
01V96, and 02R96 consoles and the DSP5D expander for the PM5D because
these devices do not have built‑in RS‑422 support. 6416Y2 A‑Net cards may
still be used with these devices for audio I/O.

Firmware Requirements

The m‑control features require firmware version 2.41 or higher in the 6416Y2
A‑Net card and firmware version 2.00 or higher in both the 6416m Mic Input
Module and any RCI Remote Control Interfaces in the system. (The RCI is not
required to use the console‑based remote control feature, but it does need
the firmware update if an RCI is installed in the same Pro64 network where
m‑control will be used.)

56m-C o n t r o l

Before attempting to use the m‑control remote control features, use the
Pro64 Update Tool software to determine a Pro64 product’s firmware version
and to update it to the latest version. The current version of the Pro64 Update
Tool application and all associated Pro64 firmware update files are available
on the Aviom website free of charge.

DB9 Cables

Using m‑control requires at least one 6416Y2 and one 6416m. A DB9 serial
cable connected between the Yamaha device and the Aviom 6416Y2 card
is required to make use of this feature on most consoles. Do not use a null
modem type cable; null modem cables are typically used with R S‑232
communications while serial cables are used with RS‑422. Place DIP switch #1
in block SW8 in the up position when using a serial cable. (The down position
should be used with a null modem cable only when connected to a PC for
firmware updates, etc.)

The LS9 does not require an external DB9 remote control connection as its
control data is passed from the console to the 6416Y2 card internally through
the backplane connector that is part of the console’s circuit board at the rear
of the MY expansion card slot.

Remote Control Emulation

Aviom and Yamaha use different remote control architectures, and in order
to provide the convenience of console‑based control, Aviom emulates
Yamaha’s remote control scheme and presents remote controllable mic pre
channels as “virtual devices” to the Yamaha console. Yamaha host devices
associate external remote controllable mic preamps, referred to as Head
Amp (HA) Devices, with their mini‑YGDAI (MY) expansion card slots.

The most common remote controllable mic preamp connected to these
consoles is the Yamaha AD8HR, an 8‑channel device, so remote controllable
Aviom channels appear to the console as AD8HR devices, and all text and
graphics in the Yamaha user interface will refer to external AD8HRs. While
each block of eight channels appears to the console as one virtual device,
there is no requirement that the channels originate on the same 6416m Mic
Input Module.

Similarly, there are differences in the functions for which Aviom and Yamaha
provide remote control. In addition, the language used to describe these
settings is different. For instance, while Aviom mic preamps can be muted
remotely, Yamaha provides mute control only in the console (i.e., outside the
A‑Net network). Users who wish to have remote control of the 6416m channel
mute at the preamp must use an MCS Mic Control Surface for remote control.
When using m‑control console‑based remote control, the RCI and MCS can

still be used with the Pro64 network as an alternative means of providing
control and network monitoring.

Likewise, Yamaha displays mic gain settings using a convention that is
different from what Aviom and some other manufacturers use (for example,
a range from +10dB (minimum) to ‑62dB (maximum). The exact values vary
by product. These are really just two different ways of displaying the same
type of information. Yamaha’s method shows the level of the incoming
signal; for example, when the console HA gain setting is “‑32,” the console
is trying to tell you “the level of your incoming signal is ‑32dB.” On a 6416m,
if the corresponding gain readout is “25,” the 6416m display means “you are
adding 25dB of gain to the incoming signal.” Control settings sent from a
Yamaha device will be interpreted by the 6416m automatically and displayed
accordingly. There is no need for the user to make any translations between
the two approaches to displaying the data.

Supported 6416m Features

When using Pro64’s m‑control feature, note that only parameters available
natively on the Yamaha control surface itself and supported by the Yamaha
interface can be controlled on the 6416m Mic Input Module remotely. These
include channel preamp gain, low cut filter (referred to as a high pass filter in
the Yamaha interface), and +48V phantom power on the 6416m. The 6416m
has a fixed 85Hz low cut filter, while Yamaha consoles offer a variable range
High Pass Filter (abbreviated as HPF) in their user interface. When using
Yamaha remote control with Aviom 6416m preamps, you can turn this filter
on and off, but the cutoff frequency remains fixed at 85Hz. Editing the HPF
filter cutoff frequency from the Yamaha user interface will have no effect at
the 6416m; the cutoff frequency remains fixed at 85Hz.

The 6416m pad setting is controlled indirectly through the head amp gain
setting on the console. There is no direct command for turning the 6416m
pad on or off from the Yamaha control surface.

Physical Connections

Remote control commands between the Yamaha host console and Pro64
remote mic preamps are sent using RS‑422 communication. Many Yamaha
devices have DB9 RS‑422 jacks on their rear panel, while some others
send remote control communication directly to external devices via the
console’s multipin backplane connector where the MY format expansion
cards connect to the console’s circuit board.

For Yamaha devices with a DB9 jack for remote HA control, a DB9 serial
cable must be used to connect the console to the 6416Y2 card set up for
m‑control. No additional connections are required anywhere in the network,

58m-C o n t r o l

as all remote control commands are managed by the Pro64 devices and
transmitted via the network cabling.

In Pro64 systems where more than one 6416Y2 A‑Net Interface Card is
installed in a Yamaha console, only one of the 6416Y2 cards should be set
to provide m‑control communication and messaging between the Yamaha
host and the Pro64 network. This one card will manage remote control
communication for all 6416Y2 cards in the host console.

Channel Count and Control

As with audio I/O, the exact number of Aviom mic pre channels that can be
controlled from a console is determined by the Yamaha device’s expansion
capability, the number of 6416Y2 cards that the host’s power supply
subsystem can support, the current MY mode being used (MY8 or MY16) and
the current sample rate being used. Each MY expansion slot on a Yamaha
console provides up to 16 channels of I/O and remote control functionality.

The LS9‑32 console, for example, which has two MY slots available, can have
two 6416Y2 cards installed in it and will have a maximum of 32 channels of
external mic preamps available to be remote controlled in its user interface,
displayed in four groups of eight channels. The LS9 uses MY16 mode and
operates at 48kHz.

Use the following table to determine the number of Pro64 cards that a
particular console can support.

DIP Switches

DIP switches in block SW3 allow the user to choose a specific Pro64 channel/
Slot range to control (in groups of 16 channels) as well as the total number
of Pro64 channels available for remote control (subject to the limits of the
host console’s expansion capability as mentioned previously.) This allows
multiple consoles to be used in the same Pro64 network, each with unique
m‑control settings.

The total number of channels that a 6416Y2 A‑Net card can send to or receive
from a Yamaha host device is also affected by the sample rate being used.
In Yamaha’s MY16 mode (used for 44.1/48kHz sample rates), each 6416Y2

card (and its MY expansion card slot) will be associated with two virtual

HA devices—16 channels total. In MY8 mode (88.2/96kHz), each 6416Y2
card installed is associated with a single virtual HA device (8 channels). Not
all sample rates are available on every Yamaha console. Refer to the table
above.

Only active Pro64 preamp channels can be controlled remotely; any remote
control commands sent from a Yamaha console to inactive 6416m channels
will be ignored. As with the RCI/MCS, the 6416Y2 must be set to the same
Control Group as all 6416m Mic Input Modules to be controlled. The Control
Group is assigned using the internal DIP switches on the 6416Y2 card, and a
6416Y2 card must always be part of a Control Group when using m‑control; it
cannot be set to the “off” Control Group as the 6416m and RCI can.

m-control Remote Control Settings on the 6416Y2

On the front panel of the 6416Y2 card, set DIP switch #10 to the down position
to enable m‑control.

Note that even though multiple 6416Y2 cards can be installed in a Yamaha
digital device, only one 6416Y2 card needs to be set to provide remote
control messages from the Yamaha device to the Pro64 network.

DIP switch #10 in the down position enables console remote control. (DIP
switch handles are shown in black.)

Once remote control is enabled, DIP switch block SW3 (internally) is used to
configure the m‑control remote control parameters. The A‑Net Slots that are
controllable from a particular Yamaha device are defined by the Channel/Slot
Control DIP switches, which are DIP switches number 1 through 4 on block
SW3. This feature allows the user to choose a specific range of the Pro64
network to control from a particular console.

Any combination of the Pro64 Slot banks can be activated for control.
Channel/Slot Control settings are independent of the Slot ranges used
for A‑Net Transmit and A‑Net Receive as well as for the individual channel
activation settings for audio being sent from the console into the Pro64
network; both groups of settings must be properly configured for successful

console‑based control.

P No t e : The actual number of remote controllable channels is determined

by the expansion capability of the particular Yamaha console being
used.

As seen in DIP switch block SW9, this 6416Y2 card is set to receive channels
1‑16 from the Pro64 network (switches 7‑8 are down) and to transmit audio
from the console into channels/Slots 33‑48 of the Pro64 network (switch 5
up, switch 6 down).

A second 6416Y2 card installed in the same console should be set to receive
channels 17‑32 from the Pro64 network in order to mix all 32 6416m mic
preamp channels on the Yamaha console.

Transmit 33-48

Receive 1-16

This example shows the 6416Y2 DIP switches set to control channels 1-32 of
the Pro64 network ’s 6416m preamps (switches 1-2 up). It uses the rear panel
DB9 connector for console remote control communication (switch 5 up), as
would be typical for an M7CL or PM5D console. The DIP switch handles are
shown in black.

With DIP switch #1 in block SW8 set to the up position as shown, the 6416Y2
will send the remote control commands to the Pro64 mic preamps as RS‑422.
Use a serial cable to connect the Yamaha console to the 6416Y2 card.

After the card’s DIP switches are configured for your application, install the
6416Y2 in the host console and then connect the DB9 cable (if required) to
the 6416Y2 card’s RS‑232/422 jack. Remember to connect the DB9 cable to
the one 6416Y2 card that has been configured for m‑control console‑based
remote control in a multi‑card system.

64m-C o n t r o l

Signal Routing to the Console

Routing channels to/from MY expansion cards can be accomplished directly
from the Yamaha console’s user interface or with a computer using the
optional Studio Manager software (available from the Yamaha website at
http://www.yamahaproaudio.com/downloads). In order to route channels in
the console to and from the 6416Y2 cards, be sure that A‑Net Transmit and
Receive settings on the 6416Y2 cards (Slot range and channel activation) are
properly configured.

Clock Settings

Remember that if a Pro64 module other than a 6416Y2 card is used as the
network’s Control Master, all Yamaha devices need to be set to slave to
the external clock provided via A‑Net. If a 6416Y2 card is set as the Control
Master, all Pro64 devices will slave to the console’s clock.

When multiple 6416Y2 cards are installed in a Yamaha host device, only one
of the 6416Y2 cards needs to be set as the Pro64 network’s Control Master.

When using multiple Yamaha consoles, the second console will need to
be set as a slave if a 6416Y2 card in the first console is set to be the Pro64
network Control Master.

Refer to Yamaha’s documentation for more information about clock and sync
settings for specific consoles.

Yamaha Console UI Notes

Because the Pro64 network is emulating Yamaha’s own remote control
protocol, it is important to note that the Yamaha user interface (UI) and its
associated display screens will refer to external head amp (HA) devices as
“AD8HR” in most cases and never as “Pro64” or “6416m.”

Remote Control of Yamaha Mic Preamps

Pro64 Virtual Data Cables can be used to send control data from a Yamaha
digital console to Yamaha remote‑controllable mic preamps such as the
AD8HR. The Yamaha devices communicate using RS‑422 at a 38.4k baud rate,
with 8 data bits, 1 stop bit, and no parity.

Two Pro64 devices with built‑in RS‑422 capabilities are required to send
Yamaha remote control information. The 6416Y2 A‑Net Interface Card and the
6416dio Digital I/O Module both have RS‑422 capability. (Pro64 devices such
as the 6416i Input Module and 6416o Output Module cannot be used in this
application; they have only RS‑232 connectivity in their VDC I/O sections.)

By connecting the RS‑422 port on the Yamaha digital console to the RS‑422
port on the 6416Y2 A‑Net Interface Card, any changes to gain, +48V phantom
power, and high pass filter (HPF) made from the Yamaha control surface will
be transmitted to the remote mic preamps via the VDC. Multiple Yamaha mic
preamps can be controlled using this method by daisy chaining the RS‑422
connections; each preamp is assigned a unique ID and can be addressed
separately from within the Yamaha user interface. Note that daisy chaining
multiple RS‑422 connections requires a specially wired cable, as specified in
the Yamaha documentation.

To send remote control data from a Yamaha digital console to a Yamaha
digital mic preamp requires a short straight‑through DB9 cable (also referred
to as a serial cable) to connect the console to the 6416Y2 card. In a straight‑
through cable, pin 1 is connected to pin 1 on each end of the cable, pin 2 goes
to pin 2, etc. A second DB9 cable is used to connect the second Pro64 device’s
RS‑422 VDC port to the Yamaha mic preamps being remote controlled.

P N o t e : Do not use a crossover cable or null modem cable for this

application.

Connection Example

This diagram shows a DM1000 console with one 6416Y2 card installed
connecte d to a 6416dio Digital I/O Module and an AD8HR mic preamp.

RS‑422 is connected between the console and the 6416Y2 card and between
the 6416dio and the AD8HR with DB9 cables. Remote control data travels over
a pair of Virtual Data Cables from the console to the remote mic preamp.

DB9 cables are available with male‑to‑male, female‑to‑female, and male‑
to‑female connectors. Aviom’s RS‑232/422 port uses a male DB9 connector
and therefore requires a cable with a female connector. The format of the
connector at the other end of the cable (male/female) is dependent upon the
equipment being connected to. However, connection to other equipment
will usually require a female‑to‑female cable.

There are many different types of DB9 cables available, but Aviom selected
a pinout for our DB9 connector that would allow both RS‑232 and RS‑ 422
connections to be made with off‑the‑shelf cables. A “null modem” cable
should be used in RS‑232 mode. Unfortunately, there are several different
types of cables referred to as null modem cables. A true null modem cable
crosses pins 2 & 3, 4 & 6, and 7 & 8. Pin 5 will be connected straight through,
but pins 1 and 9 will not (though pin 1 will be connected to pin 6 at each
end). An example of this type of cable is the L‑Com CSNULL9FF‑XA (where X
= cable length).

An example of the type of null modem cable that should be avoided is the
L‑Com CSNULL9FF‑X (where X = cable length). This is a straight‑through cable
with the exception of pins 2 and 3, which are crossed.

A true null modem cable is required for the interaction of the RS‑422
termination on pin 4 of the connector with the RS‑232 signals. On an RS‑232
connector, pins 3, 4, and 7 are outputs; pins 1, 2, 6, and 8 are inputs. In a
standard null modem cable, pin 4 at one end of the cable will drive pins 1
and 6 at the other end. With a 100 ohm resistor across pins 3 and 4 on the

84sP e C i f i C a t i o n s

Aviom DB9 connector, pin 3 (RS‑232 –Tx) will drive pins 1 and 6 at the other
end of the cable through the 100 ohm resistor. This isn’t a problem for most
modern RS‑232 implementations as these signals are ignored, and both are
inputs.

Although there is no standard DB9 pinout for RS‑422, the 6416Y2 requires
that a straight‑through cable be used between the Aviom and Yamaha
RS‑422 ports. An example of this type of cable is the L‑Com CRMN9FF‑X
(where X = cable length).

If a problem is encountered with the RS‑232 operation, there are two things
that can be done:

Try another brand of null modem cable. 1.
Cut the wire in the cable going to pin 4. It isn’t needed for 2.

RS‑232 operation.

P No t e The Aviom RS‑232 port does not support the CD, DTR, DSR, RTS,

CTS, or RI signals.
