Telos VX enables high-definition talk shows
Telos VX enables high-definition talk shows Callers with SIP connections get 2x the audio bandwidth
27 July 2011, Cleveland Ohio, USA
Telos VX, the world’s first broadcast VoIP talkshow system, has already generated lots of buzz among broadcasters wowed by its powerful next-generation Telos digital hybrids, the easy scalability of its Ethernet backbone, and its unrivalled call capacity – VX can manage up to 30 active calls and 20 studios.
But there’s another benefit to using VX: stations with Internet Telephony services can get "highdefinition" caller audio as well.
Here’s how it works: VX connects to standard POTS and ISDN phone lines, naturally. And it also connects to modern SIP Trunking services, enabling high-fidelity caller audio via native support for the G.722 audio codec – sometimes called "HD Audio." G.722 allows stations with SIP Trunking to receive 7kHz audio from callers utilizing SIP clients such as iPhone’s Acrobits app, or SipDroid for Android phones, while connected to 3G or 4G cellular networks. G.722 uses about the same amount of bandwidth as G.711, but samples audio at 16kHz — double that of G.711. The result: much better speech quality from callers using cell phones with SIP clients.
"VX with G.722 sounds amazing," says product manager Joe Talbot. "Some VX clients are even using G.722 with ‘wideband’ SIP phones to get high-quality news, traffic and weather from news bureaus or off-site talent, without the cost of ISDN."
VX comes with advanced audio tools which ensure that calls always sound their best. Famous Telos Digital Dynamic EQ, Smart AGC, and a three-band adaptive spectral processor produce superior caller audio. Send audio gets sweetened, too, courtesy of an AGC/limiter, frequency shifter, and FhG’s Advanced Echo Cancellation routines that eliminate echo and feedback in open-mic environments. VX connects easily to Livewire™ networks via Ethernet, and to standard studio systems via analog or AES audio interfaces.
VX users can choose from a variety of ways to take control of their phones:
- The beautiful new 12-line VSet12 phone has a big, bright LCD color display with exclusive Telos Status Symbols™ to keep talent informed of line and caller status. When used with VX Producer call screening software, the VSet12 display also delivers detailed information such as Caller ID, time ringing-in or on-hold, and even screener comments.
- In addition to its producer/talent communication functions, VX Producer software also has a built-in SoftPhone that turns any PC with a sound card and headset/mic into a full-featured call screening station with off-air recording features.
- Call Controller modules for Axia Element 2.0 and iQ consoles allow direct control of VX hybrids right from the mixing board, so talent never has to take their eyes off the console in order to work the phones.
Additionally, Telos has partnered with Broadcast Bionics (www.bionics.co.uk) to develop PhoneBOX VX, a new version of the highly regarded PhoneBOX call management software custom-tailored to VX users with demanding formats and large studio networks. PhoneBOX VX software is a powerful, easy-to-use interface for studio communications, offering an unrivalled feature set: phone integration, email, SMS, social media, database, call history, call recording and editing, codec control, and visual talkback. Each VX system includes a copy of PhoneBOX VX Lite at no charge.
Although Telos VX is powerful enough to manage multiple simultaneous talkshows in the largest facilities, it’s also cost-effective enough to use in stations with just a few studios. For more information, see Telos-Systems.com/vx/, or visit TelosAlliance.com/contact/ to request pricing.
