InStudio

Intercoms and Talkbacks
Contributing Editor David Kirk rounds up the latest
developments from the manufacturers of broadcast
communications technology...

I

ntercoms and talkbacks are the glue
that holds a broadcast production
team together, not least when its
various members are obliged to
work remotely across multiple sites.
Covid-19 resulted in an unusually
large amount of improvisation so that
programmes normally produced under
carefully controlled studio conditions
could be created less formally. A key
component, pandemic or no pandemic,
is the discretely concealed ear-phone
which allows a presenter to receive
instructions without risk of feedback
howl. Practiced presenters can even
read from the audio equivalent of a
teleprompter though that is, or in some
cases was, more commonly a feature
of trade shows. The following article
provides an overview of the latest
intercom and talkback tools from the
leading players in this most essential of
all product categories.
AEQ's Xplorer is a studio intercom
system based on the company's
Xvirtual application for iOS and
Windows devices. It turns a PC into
an intercom user panel connecting
via Ethernet. It can also turn any
Apple iPhone, iPod or iPad device
into a wireless intercom panel.
When connected to a wifi network,
it provides access to a Conexia
or Crossnet wireless belt pack. A
companion product is AEQ's Xbp wifibased hardware intercom panel which
combines the Xplorer application
management with the pro-cessing
and connectivity of an Apple iPod.
Four physical keys provide access to
16 possible communication channels
displayed on the main screen. Volume

AEQ Xplorer wireless intercom user panel

and mute controls are included as well
as an indicator showing the charge
status of the booster battery.
BroaMan has introduced a new
'standard' version of its Route66
configurable router offering automatic
routing via an Optocore-powered fibre
patch bay. It is designed for use in
installations with multiple connection
points and mobile stage boxes as
well as live events and broadcast.
Occupying 2U, the Route66 allows
routing of fibre/copper cables via
software instead of a manual patch,
enabling automated IP workflows
and remote cable management. It
also allows fibre/copper conversion
without external devices. The platform
itself provides single channel nonblocking 40 x 40 router ports. The new
standard version offers 40 SFP+ slots
for 40 hot-swappable bi-directional
SFPs, each slot handling up to 4Gbit/s.
Glensound's Expedition is a portable
broadcasters'
phone
compatible
with 3G UMTS and 4G LTE networks.
It also offers normal narrow-band
connections over 2G, 3G and 4G. The
Expedition has two microphone/
line/48 volt inputs that are separately
switched, and two 6.35 mm headphone
outputs. Two commentators can take
the unit to a field event and operate
as a commentary team. A reporter
can give an interviewee a dedicated
microphone and headphones. A
small ENG crew can have off-air/IFB
with monitoring for the talent and
cameraman. The Expedition has a
configuration screen for easy dialling,
caller ID display and signal strength
metering.
JK Audio's Interchange
allows remote access to
a party-line intercom
through the company's
Innkeeper
half-rackwidth interface. This
provides a four wire
audio
and
remote
control connection for
plain-old-telephonesystem lines or video over
IP lines. The front panel
headset interface jack
allows connection of a mobile
phone, tablet, or computer.

Riedel
Communications
expandable Bolero intercom

Pliant Technologies' MicroCom
M wireless intercom is powered
from a 10-hour-rated lithium ion
battery and accommodates up to
five full-duplex users. It is claimed to
provide unlimited listener capability
in addition to duplex users without
need for a base station. Up to four
MicroCom M systems can be deployed
in the same area at the same time.
RF technology based on encrypted
Frequency Hopping Spread Spectrum
transmission is used. Pliant's series
of SmartBoom headsets has been
expanded to include versions for use
with MicroCom M belt packs.
Riedel Communications' Bolero
is an expandable full-roaming
DECT-based intercom using the
license-free 1.9 GHz frequency range.
Integrated into Riedel's Artist digital
matrix intercom platform, Bolero
can be used as a wireless belt pack,
wireless key panel or a mobile radio
transmitter. Decentralised antennas
connect to AES67 switches and then
to Artist frames equipped with AES67
client cards. The belt packs support
Bluetooth 4.1, allowing either a
Bluetooth headset or a mobile phone
to be connected. When a mobile phone
is connected, the belt pack can act like
an in-car hands-free phone setup so
users can receive calls on their phone
and talk/listen via their belt pack
headset. Users can also connect a call
into the intercom matrix, eliminating
the need for a telephone hybrid.
The belt pack itself
features six buttons for
each of the six intercom
channels, plus a separate
reply button accessing the most recent
channel that called.

RTS offers a range of digital
matrix intercoms using VHF and
UHF for full duplex wireless partyline communications. Wifi and DECT
versions are also available. The DECTbased system Roameo connects to
the matrix using the Omneo matrix
interface which is the same card used
for all other Omneo and third-party
Dante-compatible
devices.
Each
system has two channels. Current
products include the BTR-800, BTR80N and BTR-700.
Sonifex recently introduced two
new audio-over-IP commentator units.
Both are smaller than the existing
Sonifex CM-CU1 single four-wire unit
and include more features. Model
AVN-CU2-Dante has two mic/line
inputs with a wide, adjustable gain
range and +48 volt phantom power
as well as two stereo headphone
outputs with lockable jack sockets. It
uses power-over-Ethernet via Neutrik
EtherCon connectors, with primary
and secondary ports for power and
network data redundancy.
