Power and Redundancy
The units are mains powered and have
two internal power supply units, providing
PSU redundancy.
As standard, one IEC input connector
is fitted to power both internal PSUs.
Versions of each unit (with the ‘P’ suffix
after the unit number, for example
AD5600P) provide a second IEC inlet.
The twin IEC approach supports mains
supply redundancy, as well as internal
power supply component redundancy.
The units incorporate a cooling fan
module.
Each PSU module and the fan
module within the unit are monitored to
ensure proper performance. PSU OK and
FAN FAIL indication is provided on the front
of the unit.
Status LEDs
The following indicative LEDs are visible
from the front panel:
PSU OK (green)
Fan Fail (red)
Port 1 connected (yellow)
Port 1 active (green)
Port 2 connected (yellow)
Port 2 active (green)
Status (x 8 red)
In addition, each input connector has
its own tricolour LED to indicate signal
presence. With analog signals the
incoming signal will cause the LED to
light green when the signal is between
-60 dBFS and -38 dBFS, amber when
between -38 dBFS and -2 dBFS, and red
when the signal clips at -2 dBFS or above.
Each output connector has a green LED
to indicate that there is a route established
to it from a console on the network.
Synchronization
Units are frequency synchronized using
synchronization packets received from the
Hydra network.
Diagnostics
The units support remote FPGA firmware
and software updates across the network
via the Ethernet ports. In addition, an
RS232 port is provided, such that system
diagnostics can be performed by a Calrec
approved engineer. Connection to the
port is via a front-mounted 9 pin D-Sub
connector.
Surround Signals
It is not recommended that ports on
a modular Hydra I/O box should be
combined with ports on a fixed Hydra I/O
box to create a 5.1 surround signal.
