The 6416o v.2 Output Module is designed with increased output level flexibility to simplify connectivity with amplifiers, powered speaker systems, mixing consoles, and recording devices, and increase the flexibility of Aviom's high-fidelity digital audio networking solution. The 6416o v.2 can be used anywhere that analog outputs are required in a system: on stage or at front of house in a digital snake, in the studio, or even in the most complex audio networks, making it ideal for live sound reinforcement, broadcast, and other audio distribution applications. Adding a digital split to a system is as simple as connecting an additional 6416o v.2.
The 6416o v.2 provides 16 balanced XLR mic- or line-level analog outputs from a Pro64 A-Net network. Each channel includes a four-position output level switch (+24dBu, +18dBu, +4dBu, and mic) and three-segment level metering. Alternate audio outputs are provided via DB25 multipin connectors on the rear panel.
Each 6416o v.2 can be configured to operate within a specified channel/slot range within the Pro64 network, making complex installations easy to configure and manage. Each output channel of a 6416o v.2 can be made active as needed.
The Pro64 A-Net network supports three ranges of variable sample rates: 44.1/48kHz±, 96kHz±, and 192kHz±. No matter the sample rate, all 16 output channels on the 6416o v.2 are available for use. All audio is streamed at 24-bit resolution with no data compression at any time.
In addition to its audio capabilities, the 6416o v.2 also includes the innovative Virtual Data Cables™ for simultaneously distributing up to 14 channels of non-audio control data such as MIDI, RS-232, and GPIO to any device on the Pro64 network. Every Pro64 I/O module comes with its own set of VDC™ ports that can be individually configured.
The 6416o v.2 is fully compatible with all Pro64 devices, including the dual output level 6416o. Any combination of 6416o and 6416o v.2 modules can be used in a system as the needs of the application dictate.

This basic Pro64 digital snake system provides 16 remote controllable mic inputs on stage via a 6416m Mic Input Module, analog outputs (mic or line level) at FOH via a 6416o Output Module, and 16 analog returns from FOH to stage. Remote control is provided via the MCS connected to the RCI Remote Control Interface at FOH.
The system can be expanded by connected additional mic input modules on stage and output modules at FOH. Output splits, such as for a recording rig, can be added to any open A-Net port anywhere in the system.
This system combines a 32x16 Pro64 digital snake with the flexibility and control of a Pro16 Monitor Mixing System.
Thirty-two inputs are provided on stage via two 6416m Mic Input Modules, remote controllable from FOH with the MCS Mic Control Surface. These signals are connected to the analog FOH via two 6416o Output Modules. Up to 16 return signals can be passed from the console back to processors on stage via a 6416i Input Module at FOH and a 6416o Output Module on stage.
Audio for the monitor system is supplied from the console to a second 6416i at FOH. The ASI A-Net Systems Interface module on stage passes this audio data to the A-16D Pro and the Pro16 Personal Mixers.
The MH10 Merger Hubs shown here allow devices in each rack to be connected in parallel and also provide a simple means for connecting backup cables between the stage and FOH racks.
This system connects up to 48 channels on stage with the FOH mix position and also provides a return path for up to 16 channels to the main processors and amps. All audio settings on the stage inputs, as well as mic pre presets, are remote controllable from FOH using the MCS. MH10 and MH10f Merger Hubs may be added in each rack for the additional security of backup cables between stage and FOH.
Splits to other locations, such as a monitor console, recording rig, or broadcast room, may be connected at any point in this system.
This 48x16 digital snake adds the flexibility of two MH10f Merger Hubs?one in the stage rack and one at FOH?allowing Stage and FOH to be connected by Cat-5e or single- or multi-mode fiber. Backup cables of either type may be added.
Both audio and control data are passed seamlessly over the fiber optic link.
On the stage, 48 mic signals connect to three 6416m Mic Input Modules. All Pro64 devices on stage
connect to an MH10 Merger Hub in parallel. A-Net from the
MH10 on the stage connects to another MH10 at the front-of-house position. The dotted line indicates a second Cat-5e cable
installed as a backup.
At the FOH position, all Pro64 devices are connected in
parallel to the MH10.
Three 6416dio modules are used to output the mic signals from
the stage to the mixing console as AES3 digital data.
The 6416m modules on stage are remote controlled
with an MCS connected to an RCI Remote Control Interface. One
of the 6416dio modules at the FOH position is used to insert 16
channels of return content into the network. Back on the stage,
the return content from the FOH position is output to the DSP
and speaker processing devices from a 6416o. (A 6416dio may be substituted for digital outputs to processors.)
The MH10f can be substituted for the MH10 hubs shown in the diagram to add fiber connectivity to this system.
A Pro64® network can be connected in almost any way imaginable with no impact on audio performance. Every cable in a Pro64 network always carries the full capacity of the network, meaning that there are no limitations on the location of input or output modules. Pro64 also supports the use of hubs such as the MH10 and fiber-enhanced MH10f when parallel connections are desired.
Because every Pro64 A-Net® port is always bidirectional and carries the full capacity of the network, all of the ports throughout a network are essentially interchangeable. If you plan to operate your system in Manual Mode (up to 64x64), connecting one device's B port to the next device's A port throughout the system will make tracking signal flow in complex systems more straightforward. If, however, your system will always run in Auto Mode, there is no need to keep track of A-Net connections.
Because the full content of the Pro64 network is available at every point in the system, an additional output (or input) location can be added anywhere in the network. Simply connect the desired module (6416o for line-level analog outputs, 6416dio for AES3 outputs, or 6416Y2 card in a Yamaha device) to any open A-Net port, set its A-Net Slot, and activate output channels as desired.
Splits may also be connected in parallel using the MH10 or MH10f Merger Hubs.
Once a signal is converted to Pro64® A-Net®, any compatible
Pro64 device can be used to output the Pro64 data as analog or AES3 digital data as
required.
Pro64 network data is also available to any Yamaha devices outfitted with 6416Y2 console cards. Pro64 uses state-of-the-art clock management to guarantee pristine audio performance at every point in the network.
Unlimited lossless digital splits (mic/line analog, Yamaha, or AES3 digital) can be created from anywhere in the network by connecting another Pro64 module with a Cat-5 cable.

The ASI A-Net Systems Interface can be used to convert Pro64 A-Net data to the Pro16 format. With an ASI installed, you can output channels from a Pro64 network to the Pro16 AN-16/o Output Module, AV-P2 Output Module, or to a personal monitoring system.
The ASI can output up to four 16-channel streams of data (at 48kHz) from a Pro64 network. At 96kHz, two streams are available(Pro64 channels 1-32), and at 192kHz, one Pro16 stream is available (Pro64 channels 1-16).
