INTRODUCTION
Calrec Audio supplies audio broadcast mixing consoles which are relied on by the world’s most successful broadcasters.
Formed as a microphone manufacturer in 1964, Calrec celebrated 50 years as audio specialists in 2014. The company’s
reputation for build quality, reliability and audio performance has made it an industry benchmark across the world.
Today, broadcasters demand even more versatility and integration from their audio equipment, and in this technologically-progressive
era TV companies want to ensure that their systems can produce programmes efficiently and to required specifications. For their
audio systems to achieve this, greater consideration has to be given to their networks as a whole, and how efficiently they can be
controlled. Calrec has designed its range of consoles to meet these demands.
Consistently pushing technology barriers, the Apollo platform introduced Bluefin2, the next generation of award-winning Bluefin
technology. It provides over 1000 channel processing paths on just one DSP card. For surround sound mixing it is the industry’s most
advanced and economical solution. In the Apollo, Artemis and Summa consoles, and the Hydra2 network, Calrec provides intelligent
solutions for easily sharing network I/O resources and control data.
This Product Guide provides detailed descriptions for Calrec’s full range of fixed format and modular Hydra2 units and both 8U and 4U
console core options.
For putting sound in the picture, broadcasters trust in Calrec.

BR-IO is a 4U Hydra2 based external
I/O Rack allowing for cost effective
expansion of I/O for use with Brio
and Summa consoles.
It is intended to be placed in control/
equipment rooms, trucks, studios, and
even outdoor use providing the user
provides appropriate protection against
the elements (flight-cases / covers /
general protection).
This rack has the same complement of
internal analogue and digital I/O that can
be found in a Brio 36 system.
External I/O Rack Audio Interfaces
The image below shows the BR-IO rack
and the Audio interfaces available to the
user from this I/O Rack are:-
24 x Analogue Mic/Line I/Ps,
16 x Analogue Line O/Ps,
8 x Digital AES I/Ps, with SRC,
8 x Digital AES O/Ps.
The Audio Specifications for the Analogue
and Digital inputs and outputs are the
same as those built-in to the Brio 36.
Port Patching Identification
The BR-IO has it’s own ICON which
appears in the I/O Boxes patching pages.
The analogue inputs and outputs are
prefixed by the Letter ‘A’ in the port
patching pages and the digital inputs and
outputs are prefixed by the letter ‘B’ for
patching purposes.
For example, where the box ID is set to
434 then Analogue Mic/Line Input 3
would be identified as 434A-03. See
below for a I/O Box / Port Patching
example.
Hydra2 interfacing
The interface controller on the right hand
side of the front panel of the unit connects
the I/O to the optional Hydra2 module in
a Brio 36 system either directly or via a
H2Hub.
Alternatively it can be connected to a
Summa Core for use with Summa.
Two Hydra2 ‘Light’ based interface
ports are provided on the BR-IO rack
for redundancy:-
Port 1 connects to the Primary H2
connection on a Brio 36 or Summa
Port 2 connects to the Secondary Hydra
2 connection on the same Brio 36 or
Summa
Multiple BR-IO units may be added via a
H2 Hub along with other I/O boxes from
the Hydra2 range.
Hydra2 based network components
interface via pluggable SFP modules, the
correct type of SFP should be ordered to
match the installation requirements.

The 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.
AoIP
A card slot within the unit will allow for
future upgrades to AoIP networking.
More information on AoIP connectivity
will be provided when module options are
available.

I/O OPTIONS – MODULAR
Modular I/O boxes are 3U rack-mount
enclosures with 20 I/O card slots
that can be populated with a mixed
range of I/O cards, allowing for a
custom selection of I/O quantities
and formats.
Modular I/O boxes connect to a Hydra2
network in the same way as Fixed Format
I/O. Multiple modular I/O boxes can
coexist on a Hydra2 network alongside
fixed format I/O if required in order to
make up the total quantity of I/O in the
format and location it is needed.
Power
Each modular I/O box is fitted with 2
x rear mounted AC PSUs, each with
their own AC IEC input operating from
100–240V AC 50/60 Hz. Either PSU
can power the whole box, two are fitted
in order to provide redundancy. Where
possible, each PSU should be fed from
a separate AC source in order to provide
redundancy against both PSU failure,
and external AC mains loss. Input power
(maximum) 100–240 VAC, 1.52–0.68A
RMS, 50/60 Hz.
Earthing
Chassis earth studs are fitted to each
PSU cover. These should be connected
to ground using earth cable of at least
6mm2 cross-section (10 AWG).
Airflow and mounting
The unit is a 19” rack-mount enclosure
designed for mounting into standard
equipment bays. Rear/side supports
should be considered in order to avoid
excessive stress on the front racking
angles, particularly if fitted into a mobile
installation.
A recessed air-intake grill runs across
the bottom of the box. The box can be
mounted directly under, or on top of
another unit or surface—the recessed
design of the intake allows sufficient air to
be drawn in from the sides (see diagram)
to cool the box. Both side facing inlets
should be left unobstructed.
Low noise fans fitted to the PSU modules
pull air through the box, venting to the
rear. To minimize fan noise and longevity,
modular I/O fan speed is varies depending
on the temperature within the box.
Hydra2 interface card
The central card slot of a modular I/O box
is reserved for a Hydra2 interface card.
This card connects the I/O to a Hydra2
network. Unlike fixed format I/O, the
Hydra2 interface connectors are on the
front of the modular I/O box.
Two Hydra2 interface ports are provided
for redundancy—port 1 connects to
a primary Calrec router, port 2 to the
secondary router in the same core. The
Hydra2 interface is via pluggable SFP
modules, the correct type of SFP should
be ordered to match the installation
requirements—Cat5e copper, singlemode,
or mulitmode fibre. Please refer to
the section on SFPs in the Installation
manuals for more detail.
The table on the following page provides
an overview of the modular I/O cards
which are currently available. More
