Network B Sample Rate Converter (SRC)

A Sample Rate Converter (SRC) is available on the Network B Dante ports, allowing the gain
compensated split outputs to run at a different sample rate or in a different clock domain to the
main network.
Example applications are shown below, note this is not an exhaustive list. Both Network A and
Network B can operate at any of the available sample rates (44.1, 48, 88.2 or 96 kHz). Sample rate
selection for each device is configured from the Device Config tab within Dante Controller.
Network B SRC is enabled from the device Setup tab within Network I/O Controller.
N.B. If Network B SRC is disabled then both Dante networks (Network A and Network B) must be
running at the same sample rate and synchronised to the same clock source.

Sharing Signals Between Consoles Running at Different Sample Rates

For events where a Front of House console is
operating at 96 kHz and a broadcast is
simultaneously being produced at 48 kHz.
Alternatively for situations where additional
networked consoles cannot operate at 96 kHz.
Network A is set to 96 kHz. The FOH console
subscribes to the main audio channels and
has ownership of the mic preamps.
Network B is set to 48 kHz and Network B
SRC is enabled. The broadcast console
subscribes to the gain compensated split
outputs available from this network.
The Network A+B Link can be enabled or
disabled depending on the network infrastructure. If enabled, both networks will share a common
PTP clock.

Sharing Signals Between Networks in Separate Clock Domains

For situations where two independent
networks require access to the same stagebox
inputs but have separate clock sources, for
example an event with a FOH network and
separate OB truck.
Network A is set to 48 kHz. The FOH console
subscribes to the main audio channels and
has ownership of the mic preamps.
Network B is set to 48 kHz and Network B
SRC is enabled. The OB truck subscribes to
the gain compensated split outputs available
from this network.
The Network A+B Link will be disabled, with
the additional benefit that stagebox control is unreachable from Network B.
