Telos VX

Meet Telos VX: the future of broadcast talkshow systems.

VX is the world’s first VoIP talkshow system. It’s incredibly powerful, incredibly flexible, and highly scalable -- a powerful wholeplant broadcast phone system that’s also economical enough for stations with just two or three studios. VX connects to traditional POTS and ISDN telephone lines via standard Telco gateways. But it can also connect to VoIP-based PBX systems and modern SIP Trunking services to take advantage of low-cost Internet-delivered phone services. Using standard Ethernet as its data backbone, VX significantly eases the cost of phone system installation, maintenance and cabling, while making it easier than ever for talent to take control of their phone system. VX is truly the future of broadcast phones.

 

VX: Where phones and IP networking intersect.

With the VX, we’ve wedded the capability of modern networking to the remarkable power of today’s digital processing to bring the benefits of the resulting synergy to broadcast facilities. With VX, you can move and share lines between studios at the touch of a button. VX is naturally scalable, capable of serving even the largest of facilities — while remaining surprisingly cost-effective for even single stations with more modest needs. To make the most of this networked environment, we’ve built VX around the VoIP (Voice over IP) standard.

Why VoIP for broadcast?

VoIP has taken the business world by storm, increasing the flexibility of office phone systems and PBXs while simultaneously lowering maintenance and equipment costs. In fact, most Fortune 500 companies have replaced their older PBX systems with VoIP for just these reasons.

VoIP is a natural for broadcasters, interconnecting the phone system CPU with audio interfaces, phone sets, console controllers, and PCs running screening software by way of efficient, low-cost Ethernet. Using VoIP, you can finally share phone lines among multiple studios and route caller audio anywhere in your facility, easily and instantly. Got a hot talkshow that suddenly needs more lines in a certain studio? Just a few keystrokes at a computer and you’re ready — no delays, and no cables to pull. VX can even connect with your business office’s VoIP PBX to allow easy call transfers.

Reduced cost. Increased flexibility.

This sophisticated networking allows rich communication between devices. For example, caller information entered by a producer is displayed on the studio phone’s color LCD. Caller audio is available on studio PCs for easy recording. Operators at mixing consoles can directly control line switching without taking their attention from the board.

The VX system’s standards-based VoIP architecture helps you save money, too, by widening your choices in telco providers. You can connect to traditional POTS or ISDN phone lines using standard telco gateways — or connect to pure VoIP services using modern SIP Trunking, which can deliver substantial savings to stations that need a large number of lines.

But it’s not just VoIP — It’s VoIP from Telos. Every incoming line has its own fifth-generation Telos Adaptive Digital Hybrid, our most advanced ever — packed full of technology engineered to extract the cleanest, clearest caller audio from just about any phone line, even notoriously noisy cellular calls. Multiple lines can be conferenced with superior clarity and fidelity. Smart AGC ensures consistent caller audio levels. New Acoustic Echo Cancellation from FhG removes feedback and echo in open-speaker studio situations. And should you choose to use SIP Trunking telco services, calls from mobile handsets with SIP clients will benefit from VX’s native support of the G.722 “HD Voice” codec, instantly improving caller speech quality.


VX System Components

VX System Components

VX Engine

The VX Engine is the heart of the system. A 2RU rack-mount device with enormous processing power, the VX Engine provides all the call control and audio processing needed for the system. You can have as many as 48 lines active simultaneously — on-hold, being screened, queued for air, etc.— and up to 16 “audio connections” on-the-air at once. (Think of an audio connection as a hybrid, with each bidirectional console connection containing the audio from phone system to console and the clean feed from console back to phone system.). Its two Gigabit Ethernet ports provide a cost-effective interface to both telephone lines and studio audio via proven Livewire AoIP. VX is Web-based, so remote control and configuration are a snap — engineers can work with it from any place they can get online.

Call processing is sophisticated and flexible. Lines may be readily shared among studios; the Web interface allows easy assignment of lines to “shows”, which can then be selected by users on the studio controllers. Each studio can provide its own Program-on-Hold as well.

Audio processing features also have taken a leap forward. The processing power of the VX Engine provides a hybrid for every line, allowing multiple calls to be conferenced and aired simultaneously with excellent quality. The hybrids are equipped with a rich toolbox to make caller audio sound its best, no matter what kind of line or phone the caller uses. Caller audio benefits from Smart AGC coupled with famous Telos three-band adaptive Digital Dynamic EQ and a three-band adaptive spectral processor. Send audio gets its own sweetening with a frequency shifter, AGC/limiter and FhG’s Advanced Echo Cancellation technology that literally eliminates open-mic feedback. Call ducking and host override are part of the VX toolkit as well, and talent can manage and customize their telephone settings and workflow using VX Show Profiles to store and recall commonly used show configurations.

You’ll notice that there are no audio I/O or telco ports on the VX Engine. All connections to the Engine are via the two Ethernet jacks that connect to your system’s Ethernet switch to support a wide variety of peripherals: telephone lines, Livewire studio audio, VSet phones, VX Producer PC applications, console-integrated controllers, etc.

For traditional phone services, you can choose standard telco gateways from Patton, Cisco, Grandstream and others to connect to T1/E1, ISDN, and POTS providers. And, if you have a VoIP-based PBX or SIP Trunking telco service, the VX uses standard SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) to direct up to 48 simultaneous on-air phone calls.

VSet12

VSet12
The VSet12 phone controller
is an IP-based phoneset with two large, high-contrast color LCD panels that provide line status and caller information. VSet phnes can work like a traditional Telos controller, with calls being selected, held, and dropped in the way to which operators have grown accustomed. But because the VX system has a hybrid per line, much more functionality is unlocked: you can now spread multiple calls over a number of faders, using one for each call so that operators can control each line’s level individually. You can hard-assign individual lines to fixed faders, such as for VIP calls. You can even map groups of lines to a single fader.

VSet Controls

Easy-to-understand VSet controls, with a friendly visual interface, let talent manage incoming lines, lock calls on-air, start an external recording device, and take a queue of calls to air sequentially, for precise management of multi-call interviews or conferences. The LCD displays deliver detailed line status, caller information, caller ID, time ringing-in or on-hold, and even comments entered in the VX Producer screening software application. Shown above are a few of the attractive, instantly-understandable Status Symbols that help talent run tight, mistake-free shows.

A built-in address book and call history log round out VSet12’s features. As with the rest of the VX system, each VSet12 has its own web server for easy remote configuration and software upgrades.


VX Producer

VX Producer

VX Producer comes with every VX Engine purchase, and has a site license for deployment throughout your entire facility. Its intuitive, user-friendly interface provides the usual call screening functions for phone-active broadcasts (caller status, screener’s comments, Caller ID, time-per-call for up to 12 lines) – but with a number of enhancements enabled by the IP nature of the VX system.

For instance, VX Producer’s integrated softphone uncomplicates the producer’s life, since the PC interface is used for all operations, including answering and making calls, assigning priority, writing notes, etc. It also reduces cost, as no hardware phone is needed.


VX ProducerVX Producer also has a built-in audio recorder/editor with which a producer can record and edit a phone call without leaving the application. A producer can readily record calls for later play, which can be edited with a PC application running on the same machine, then sent to the on-air studio or talent’s PC over the network for quick and convenient airing.

Like the VSet12, VX Producer includes an address book and call history log. There’s also a Chat function that lets producers and talent communicate quickly via off-air instant messaging. And VX Producer is included at no extra cost with every VX Engine purchase.




VX Interfaces

VX Audio and Logic Interfaces let you connect VX to any non-networked radio console or other broadcast equipment, using standard analog or AES/EBU interfaces. A GPIO Logic interface provides control logic where needed.

VX Interfaces

The VX Analog audio interface
has eight balanced stereo inputs and eight balanced stereo outputs, presented on easy-to-install RJ-45 connectors. The inputs are switchable to accommodate consumer level -10dBv or professional level +4dBu. Outputs are shortcircuit protected and capable of delivering up to +24dBu before clipping. Superior performance specs include 102dB of dynamic range, <0.005% THD.

VX Interfaces
The VX AES/EBU audio interfaceprovides eight digital AES3 inputs and outputs, each on a separate RJ-45 connector. Studiograde performance specs, like 138dB of dynamic range and <0.0003% THD.

VX Interfaces

Each VX GPIO logic interface has eight assignable logic ports. Each port contains 5 opto-isolated inputs and 5 opto-isolated outputs, which can be associated with audio input peripherals and/or output destination devices to provide machine start/stop pulses, lamp drives, and transport controls. Once a port is configured to be associated with a particular device, it automatically activates with that device.
