The Calrec Fieldbox provides 8 balanced analogue mic/line level inputs, and 8 balanced analogue line level outputs, in a compact, cost-effective package.
Enclosure
The Fieldbox is 220mm wide x 384mm deep x 40mm (<1U) high. Threaded fixing holes in the base allow the unit to be secured in place if required.
Cooling
This is a fanless design that is cooled through natural convection and radiation. If not being used in a cooled environment, please allow for 45mm (1.75') clearance on the top and sides from other heat generating equipment.

Power
The Fieldbox contains a single AC mains PSU that can be fed 100-240V AC via
a rear mounted IEC connector. The IEC connector has a retaining clip that can hold some types of IEC cables in place. The cable supplied with the unit has a built in latching mechanism and does not need to be clipped in place.
A 10-30V DC input allows an optional external PSU to be connected to provide power redundancy if required.
Battery powered operation
The DC input is also suitable for use with batteries. Batteries can be used as a backup to the internal AC supply, or as the primary power source. There is no drain on the battery whilst the unit is fed with AC, yet switch-over from AC to DC is seamless.
System Status warnings are issued across the network and front panel LED indication is provided if the battery level is low.
A wide range of suitable batteries are commonly available from
broadcast suppliers. Costs vary significantly based on run time and
other factors. Calrec recommends the use of Anton Bauer G150 batteries
in conjunction with their QR-UNIV XLR mount to provide a runtime in
excess of 12 hours. 'Hot-swap' battery mounts are also available to fit 2
batteries that can be individually swapped out without interrupting
operation.
The DC input is protected by ISO 7637-2 circuitry against surges, reverse polarity and other external power faults.

Hydra2 network connection
A pair of rear mounted SFP slots provide primary and secondary connections for a Hydra2 network. Various fibre and copper SFP modules can be supplied.
Note that SFP design varies depending on manufacturer, please ensure that SFPs are correctly latched in place after fitting them. In the event that a connection is not automatically established after hot- plugging an SFP, please reset the unit the SFP is plugged in to.
Like all other Hydra2 I/O, the Fieldbox must be given an ID, unique amongst
all the I/O on the network, before being connected. The ID is a value from 1 to 255, set as a binary representation using DIP switches accessible from the rear.
For further guidance, please refer to the I/O Box Identification section, under Fixed Format I/O in the Hydra2 Installation manual.
Another DIP switch accessible from the rear sets whether the unit is to network via Hydra2 or AoIP. Please ensure this switch is set to the Hydra2 position for normal operation.
