RO64 USER INTERFACE
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
device designated as the system’s Control Master.
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. Channels
are sent into the network and can be shared 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 hardware output channels that can use a given
A-Net Slot. The actual number of available Slots is determined by the
current sample rate. The maximum number is 64 active channels at the
44.1/48kHz sample rate.
Sample Rate Available A-Net Slots in Auto Mode
44.1/48kHz 64
88.2/96kHz 32
176.4/192k Hz 16
Manual Mode
When more than 64 channels are needed in a network, 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 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
