Intercom Systems & Talkbacks
Contributing Editor David Kirk rounds up the
latest from the manufacturers of intercoms,
talkback and networked microphone systems...

I

ntercoms and talkbacks are the glue
that hold broadcast productions
teams together. Unseen and usually
but not always unheard by television
and radio audiences, they have been
the subject of fast development over
the past 12 months, particularly in
following the industry-wide pattern of
embracing IP. The following summary
describes the latest offerings from
all major manufacturers known to be
active in this product category.
Audio Ltd's 1010 digital wireless
microphone system allows up to 20
systems to be operated together.
Transmitter and receiver have OLED
menu driven select-and-click displays.
Brightness can be reduced or the
screens and LEDs switched off entirely.
A free downloadable app will control
the main functions on the transmitter
from an Apple iPhone or iPad as well
as monitoring battery levels. The units
have black anodised cases machined
from solid aluminium with rounded
corners and recessed buttons on
the TX1010 transmitter. The DX1010
receiver has a pivoting OLED display.
Measuring 83 x 64 x 18 mm, the
TX1010 transmitter can operate at 5,
20 or 50 milliwatts power level and is
driven by two 1.5V LR6 AA cells housed
in a hinged lockable compartment.
A built-in SD card reader can be used
to update the system's firmware and
capture the live audio stream.

CTP Systems' DBC1-24 camera talkback controller

Broadcast Bionics' XScreen is
designed to augment Telos multi-line
phone systems and VSets supporting
the company's VX, HX6 and iQ6
intercoms. XScreen software provides
call control, call screening, data
capture and chat features, allowing
an operator to answer, screen and
route calls across multiple PC clients.
A cloud-based database keeps a log
of calls and provides further alert
and directory capabilities. XScreen
can record and manage caller audio
(Livewire systems only). It can also
act as a soft phone for talking to and
screening callers directly through
a USB headset or sound card on an
XScreen client PC.
Clear-Com's new Dante interface card
for the Eclipse-HX matrix (E-Dante64HX) made its US debut at the April
2017 NAB Show in Las Vegas. The card
is compatible with the Eclipse HXOmega, Median, and Delta, supports
Dante and is AES67 compatible. It can
transport up to 64 channels of audio
to multiple Dante-enabled devices
using standard Ethernet network
infrastructure. The E-Dante64-HX,
with 64 ports, is claimed to be the
highest available density for a Dante
card on the offering both primary and
backup network interfaces. The card
can be operated at all standard sample
frequencies including optional 96
kHz/32-channel.
CTP Systems' DBC1 provides audio
comms for up to 24 camera channels.
It offers full control over every aspect
of camera talkback and programme
sound feeds using only one port of the
main talkback system. The DBC can be
used independently or integrated into
a current talkback system using GPIs.

Clear-Com
E-Dante64-HX

Delec's Oratis Compact is a reducedsize version of the company's Oratis
intercom unit and summing audio
matrix. Features include fully summing
(non-blocking) audio, 48kHz sample
rate, 24-bit word length, external

JK Audio Interchange LTD party-line system

sync support and optional networking
using the Delec Link protocol (Gigabit
Ethernet layer 2). It is expandable to
64 Dante channels
Glensound's Expedition is a portable
broadcasters'
phone
compatible
with 3G UMTS and 4G LTE networks.
It also offers normal narrow-band
connections on 2G, 3G and 4G
networks. 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 top
panel screen allowing easy dialling,
caller ID display, signal strength
metering, and configuration.
JK Audio's 'Interchange LTD' allows
remote access to a party-line intercom
system. Its 1RU interface includes
a digital hybrid for connection to
analogue phone lines. The front panel
headset interface jack allows direct
connection to a wireless phone, tablet
or computer. The internal digital
hybrid connects intercom audio to
a standard analogue telephone line
without the transmit/receive crosstalk
common
to
analogue hybrids.
Lectrosonics has
introduced the PDR
micro digital recorder
for
situations
in
which the distance
is extreme or a
wireless microphone
is not practical. The
PDR records 24-bit
48kHz wav files onto
a Micro SD card and
can be synchronised

to external timecode via the standard
5-pin Lemo connector. A headphone
output jack allows monitoring of the
signal input or listening to previously
recorded files. The input connector is
the industry standard TA5M jack that
accepts any mic or line level signal,
and provides power to a variety of
electret microphones. The input
connection and wiring are compatible
with microphones pre-wired for use
with Lectrosonics professional wireless
microphone transmitters with servo
bias type inputs. The PDR is rated
to run for over six hours on a single
lithium AAA cell.
Pliant
Technologies'
CrewCom
wireless intercoms are available for
use in 2.4 GHz and (where legal) 900
MHz bands. A proprietary network
called CrewNet coordinates and
transports all system timing, audio,
signalling, and controls. CrewNet is
capable of operating over standard
Cat-5e (or greater) and/or single mode
fibre lines. CrewWare software allows
offline configuration, online control
and real-time monitoring of all system
components.
Riedel Communications' Bolero is
an expandable, full-roaming, DECTbased intercom in the license-free 1.9
GHz frequency range. Integrated into
Riedel's Artist digital matrix intercom
platform, Bolero can be used as a
