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 rates above 96kHz are not compatible with Yamaha

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
