Intercoms and Talkbacks
Contributing Editor David Kirk examines
crucial studio production technology...

S

ix months have passed since
we previously essayed into
the Intercoms and Talkbacks
product category. As ever,
this is arguably the most
important element of the
entire production chain as it
integrates crews across various
locations as a single team.
Significant trends are towards
more compact form factors and
greater user of IP networking.
Audio Limited's new A10 wireless
digital link comprises the A10-TX
portable transmitter and A10-RX
receiver with a claimed 20kHz audio
bandwidth, high dynamic range,
ultra-low distortion and 2ms latency.
It operates in the 470MHz to 694MHz
UHF band, frequency ranges being
country-dependent. Up to 29 A10 links
can operate simultaneously in a single
8MHz TV channel.
Broadcast Bionics' Skype TX for
Radio enables broadcasters to deliver
full multi-line talkshow and contest
formats via Skype from a single PC.
PhoneBOX4 integrates Skype calls
alongside traditional phone lines, SMS
and social media. Skype TX for Radio
is a Windows service which can run on
existing PCs or be hosted as a virtual
machine. Up to 14 lines of Skype can
be delivered from a single server.
Clear-Com introduced the latest
enhancements to its HelixNet digital
networked party line intercom at AES
NY 2017. The latest features include
binaural listening in the HelixNet HXIIBP-X5 beltpack, a six-fold increase
in input/output ports, and direct
connections to the Agent-IC mobile
app and VoIP phones. The HelixNet
HXII-BP-X5 Beltpack now features a
binaural (split ear) function enabling
programme feed from one channel
to one ear while the feed from the
intercom channel is heard by the other
ear. This feature adds to the existing
capability of mixing audio from both
channels in both ears. By connecting
Clear-Com LQ Series devices to the
HelixNet Mainstation via an Ethernet

Audio Ltd's A10 wireless digital link

module, users can assign up to 24
audio I/O ports to any of the 12 or
24 intercom channels in HelixNet.
These supplement the HelixNet ports
for interfacing with two-wire and/or
four-wire intercom or audio devices.
HelixNet and LQ are linked over LAN
and WAN IP networks. Signals from
any remote devices are routed over
IP to the assigned HelixNet endpoints.
Through the LQ interface, any user
on the HelixNet system is now able
to communicate with users on ClearCom's Agent-IC mobile apps running
on smart iOS or Android devices over
Wi-Fi, as well as users on VoIP phones
via SIP connection.
CTP Systems' FWD8000 is a Dante
enabled four-wire box with eight fourwire inputs, eight four-wire outputs
plus eight IFB inputs. In addition to
the network connections, four of
the four-wire inputs and outputs are
mirrored onto the rear of the unit for
local analogue use as well as two IFB
inputs. Power can be supplied via PoE,
an external 12 volt supply or IEC mains
inlet. Each channel has a cut switch, an
IFB monitor button plus an incomingaudio-present indicator. Units can be
supplied with a headphone jack or a
five-pin XLR headset connector. An 'all
talk' key can be set to talk to any or all
of the four-wire outputs. A microphone
cut button is also provided. When a
talk key is pressed, incoming audio to
the loudspeaker is normally dimmed to
prevent feedback. This attenuation can

be adjusted or defeated as required. and export markets, and B2 (563 -
