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
Page 13

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.

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.

receptacle. Remove the cover plate on the Yamaha • device’s expansion
slot to expose the expansion connections. Discharge any built‑up static charge by touching the metal •
casing of the host Yamaha unit. Remove the 6416Y2 card from its protective anti‑static •
sleeve. Ensure that the 6416Y2 card DIP switches are set properly •
for your application at this time. Slide the 6416Y2 card into place, aligning the sides of the •
card with the support guides in the MY expansion slot. Press the 6416Y2 card firmly in place to attach the multi‑•
pin connectors on the card to those on the expansion slot backplane on the Yamaha device.
Tighten the thumb screws on the 6416Y2 to secure it.• Power up the Yamaha digital device. • Connect the 6416Y2 to a Pro64 network. •
Once the Aviom expansion card has had its DIP switches configured and is installed in the Yamaha host device, all audio routing to/from the 6416Y2 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
8main ta i ni n G Yo u r Pr o 64 Pr o d u C t
Page 19
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
Page 21
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
Page 22
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
Page 24
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.

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.
Sample Rate
4 4.1/4 8k Hz 64
88.2/96kHz 32
176.4/192kHz 16
P No t e : Sample rates above 96kHz are not compatible with Yamaha
devices.
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
Page 29
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:

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.

Setting Control Master Status

Setting the 6416Y2 to be the network Control Master is done using the DIP switches found on the front panel. The Control Master is set with switch 12, found in the same DIP switch block as the Stereo Link section of the interface.
DIP switch 12 (shown in black) is used to set the Control Master status for a 6416Y2 card.
Move DIP switch 12 to the down position to make the 6416Y2 card the Pro64 network Control Master.

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
Page 34
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:

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

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
Page 35
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.

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
Page 42

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 follows the table. Also note that Switch Block SW7 is on the front panel of the card, facing the user.

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.
This example shows block SW8 with an RS-422 port assigned to VDC Slot 5-6. Switch handles are shown in black .

Network Mode (Auto/Manual)

The Pro64 network can be set to operate in either Auto Mode or Manual Mode using switch 1 in DIP Switch Block SW9. The default setting is Auto Mode.

A-Net Transmit Settings (Manual Mode)

The 6416Y2 A‑Net Interface Card can transmit its activated channels to A‑Net Port A, B, or both A and B when the network is running in Manual Mode. (This setting does not apply when the network is operating in Auto Mode.) Use switches 2 and 3 to direct A‑Net data to a specific port.

The 6416Y2 card can transmit its activated channels to an 8‑channel (MY8 Mode) or 16‑channel (MY16 Mode) block of slots within the Pro64 network. Switches 5 and 6 are used to determine where in the Pro64 network activated channels from the Yamaha device should be sent. Base Slot refers to the first channel number in a group of 8 or 16 channels.

By default, A‑Net Slots 1‑16 are assigned to the host Yamaha device when operating the card in MY16 Mode. One group of 16 channels is always assigned to be available to the Yamaha host device. In MY8 Mode, 8 channels are available.

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.

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
Page 59
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
Page 61
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
Page 65
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
Page 66

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
Page 67
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
57m-C o n t r o l
Page 68
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
Page 69
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

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

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.

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.”

The LS9 External HA screen includes the following setting:
1. COMM Port Setting — Set this to the same MY expansion slot where the 6416Y2 card being used for console remote control is installed. Setting this field to the Off setting (‑‑‑‑) will stop all remote control communication. Use the De c /IN c keys to select a port, and then press the eN t e R key.
2. Remote Preamps ID — Available remote controllable pre‑ amps are shown in groups of eight channels; note that the device name is always displayed as “AD8HR.” The red “+48V Master” text indicates that the remote AD8HR preamp’s master on/off switch for phantom power is on. The 6416m does not have a separate phantom power master on/off switch, so this parameter will always be on.
3. Expansion Slot Port Assignment — Use this field to assign channels of the 6416Y2 card(s) installed in the MY expan‑ sion slots to the groups of eight remote mic preamp channels. Each 6416Y2 offers two groups of eight channels, 1‑8 and 9‑16, at the 44.1/48kHz sample rate.
4. Virtual Mic Preamps — This overview shows the current level setting for each remote mic preamp device connected.
Selecting one of the virtual mic preamp fields and then hitting the eN t e R button on the LS9 will bring up the full size External HA screen that allows all remote controllable parameters to be viewed and edited, displayed in groups of eight channels.

Only active Pro64 channels on connected 6416m preamps can be edited. Remember that the HPF parameters can only be set to on/off; the high pass filter cutoff frequency parameter does not apply to the 6416m Mic Input Module. The device type will always be displayed as “AD8HR” as Pro64’s m‑control is emulating this protocol. All changes made from this screen are instantly transmitted to active 6416m channels on the Pro64 network.

Assigning Remote Preamp Channels to the LS9 Faders

Each mixer channel on an LS9 can be configured to use any of the console’s available audio resources, including the built‑in mic/line inputs on the LS9 rear panel and channels coming into the console via MY expansion slots. The default routings for the LS9‑16 have channels 1‑16 patched to receive audio from the rear‑panel jacks; audio from MY expansion slots defaults to channels 17 and above. The LS9‑32 has the first 32 mixer channels patched to receive audio from the rear panel input jacks, with channels 33‑64 defaulting to the two MY slots.

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.

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.

RS-232/422 Pinout

The following table shows the pinout of the RS‑232/422 jack on the 6416Y2. Note that in the pinout table, some transmit/receive functions (abbreviated as Tx /Rx) are different for RS‑232 versus RS‑422.
Pin Function
1 No Connect 2 –Rx (RS‑232), –Tx (RS‑422) 3 –Tx (RS‑232), –Rx (RS‑422) 4 +Rx (RS‑422) 5 Ground 6 +Tx (RS‑422) 7 No Connect 8 No Connect 9 Ground
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

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.

P No t e The Aviom RS‑232 port does not support the CD, DTR, DSR, RTS,
CTS, or RI signals.
