Telos VX Broadcast VoIP System

The convergence of IP-Audio and Studio Telephone Systems Telos VX is the
world's first multi-studio VoIP phone system for broadcast. It's
scalable to provide its advanced phone interface capabilities to
facilities with a few studios or dozens. VX uses Ethernet as its
network backbone, a powerful yet simple way to share phone lines
among studios and connect system components. VX plugs right into Axia
IP-Audio networks, connecting multiple channels of audio and control
via a single Ethernet RJ-45. If you don't have an IP-Audio network
yet, VX works with Axia nodes to provide analog or AES audio and GPIO
connections. The VX uses standard SIP (Session Initiation Protocol)
and RTP (Real-time Transport Protocol) protocols, so it works with
your VoIP-based PBX or SIP-trunking Telco service to direct up to 80
lines of phone traffic. Gateways allow the VX to connect to
traditional Telco lines, including T1/E1, ISDN, and POTS. Call
processing is sophisticated and flexible. Lines can be easily shared
between studios. A web interface lets you assign lines to 'Shows',
which can then be selected by users on the studio controllers. The
call screening interface uses familiar Telos Status Symbol icons to
let talent and producers know, at a glance, the status of each line.
Each studio has its own dedicated Program-on-Hold input. VX also
features our most advanced audio processing ever. Each incoming line
has its own individual hybrid, allowing multiple calls to be
conferenced and aired simultaneously with noticeably superior clarity
and fidelity. Each call may be assigned to its own fader for
individual control of volume and on/off status during conferencing.
AGC, adaptive Digital Dynamic EQ and call ducking are part of the VX
toolkit, along with a breakthrough Acoustic Echo Cancellation (AEC)
capability that solves the longstanding problem of feedback and echo
in open-speaker situations. The VX Producer PC application includes
an integrated recorder, player, and editor. A producer may easily
record and edit caller comments and send them to the studio for
on-air play. In-studio DJ-style call recording, editing, and play is
also simplified. Smooth integration with studio mixing consoles is
achieved via their common network connection. * The Telos VX system
includes: VX Engine – Call control and audio processing engine * VX
Director – IP-based call controller * VX Producer – Windows based
software for call screening, recording and editing VX Engine VX
EngineThe VX Engine is the heart of the system. This is where all
hybrids are housed, call control and audio processing occurs. Since
VX is an IP-based system, I/O is only limited by network bandwidth
and throughput resulting in an unprecedented capacity of up to 80
available incoming lines, each with its own third- generation Telos
Adaptive Digital Hybrid featuring Advanced Echo Cancellation
developed by Fraunhofer. Up to 20 studios can connect to a single VX
Engine, each with its own VX Directors and VX Producer call screening
software for control. Talent can customize their telephone workflow
with Show Profiles to store commonly-used show configurations – for
talk shows, interview segments, or anything else – and recall them
for instant use. VX is equipped with a rich toolbox to help make
caller audio sound its very best, no matter what kind of line or
phone the caller is using. Smart AGC, noise gating, a high-pass hum
filter, Telos' famous Digital Dynamic EQ, and a three-band adaptive
spectral processor are all brought to bear on caller audio, while
send audio gets its own sweetening which includes a frequency
shifter, AGC/limiter and FhG's Advanced Echo Cancellation. Remote
control and configuration? Of course. VX's web- based configuration
lets engineers work with VX from any networked location using a
standard Internet browser. VX EngineAnd since VX employs VoIP
technology, talent, producers and board ops have a wide range of
phone, console and software interfaces at their disposal. There's VX
Director, with its familiar phone-set design and big, bright color
LCD display. VX Producer call- screening software, with a built-in
soft-phone, turns any PC into a phone station. And direct console
integration with Axia IP-Audio consoles that let talent make and take
calls directly from the board. Each VX Engine supports up to 100
control devices, in any combination. At only 2 RU in height, and 15”
deep, the VX Engine can be neatly tucked away in any equipment rack.
VX Director VX DirectorThe new Telos VX Director phone is beautifully
designed, with an attractive, friendly LCD color display that uses
exclusive Status Symbols to let talent know what's going on in an
instant. VX Director can handle up to 12 phone lines, providing
detailed line status, caller information and fader assignments at a
glance. The info-rich display shows caller ID for each line, along
with time ringing-in or on-hold, and even screener comments from the
VX Producer software application. VX Director gives talent
unprecedented flexibility. You can map groups of lines to a single
fader, making it simple to take a queue of calls to air sequentially
— or use the Fader Assign function to map lines to individual
console faders for precision control of multi-call interviews or
conferences. One-touch controls let talent step through queued calls,
busy incoming lines, lock calls on-air, even start an external
recording device. A built-in address book and call history log round
out VX Director's features; as with the rest of the VX system, each
VX Director has its own web server for easy remote configuration and
software upgrades. VX Producer Product DiagramWindows™-based VX
Producer software streamlines call screening, recording and editing
with its intuitive, user friendly interface. VX Producer gives talk
show producers all the information they need, including caller
status, screener's comments, Caller ID and time per call for up to 12
lines. Like the VX Director, VX Producer's Fader Assign feature lets
you map calls to up to eight specific console fader locations if you
wish, and includes an address book and call history log. There's also
a Chat function that lets producers and talent communicate quickly
off-air using VX Producer. But VX Producer is much more than just a
call screening application. Plug a headset mic into your PC, and you
can make and take phone calls directly from VX Producer — no phone
set needed. There's also a built-in audio editing application that
lets you record, edit and play back conversations without the need
for any third-party software. When you're done editing, click "Send
to Studio" and it's ready to play on-air. Live calls or
pre-recorded, interviews or audience participation, one thing's
certain: phone segments are an integral part of today's fast-paced
radio. But up to now, the phone system was separate from the on-air
console; audio was shared, but little else. Wouldn't it be great if
talent could take control of phones without ever having to divert
their attention from the board? They can: IP-Audio networking
technology provides the ideal way to integrate broadcast phones into
the on-air console — the control center of every studio. Typical
Livewire Installation There are plenty of advantages to melding
phones with consoles. Like ease of installation: IP-Audio consoles
with built-in phone controllers don't need any additional wires or co
