Telos Systems—part of the Telos Alliance—was founded in 1985 by Steve Church, a talk show radio host and engineer who was dissatisfied with the poor quality of the on-air telephone calls on his shows. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a great success, inspiring Steve to build a business to make and sell the systems. Telos Systems has since become the industry leader in broadcast telephone systems and IP and ISDN codecs. The breakthrough Telos Zephyr audio codec, for example, is one of the most successful digital broadcast products in history, with more than 21,000 in use worldwide. Telos telephone hybrids and on-air talk show systems set the performance benchmark for the industry, and we continue to pioneer groundbreaking technology that pushes boundaries and gives broadcasters the telephony solutions they need for reliability, efficiency, and the best possible sound quality.
Broadcast Telephone Systems
VX is the world's first VoIP (Voice over IP) talkshow system - a SIP-based broadcast phone system so powerful it can run all of the on-air phones for your entire plant, but economical enough for stations with just two or three studios.
VX Prime is the little brother to the full VX Broadcast Talkshow system, offering the same level of high performance to smaller facilities with two to four studios—all on an IP backbone that sounds better and costs less.
Hx6 is the six-line, dual-hybrid broadcast phone system that makes your on-air phones sound great, at a price that's startlingly affordable. An Hx6 in your studio is like an instant audio upgrade for POTS phone lines.
With decades of experience designing broadcast phone systems, it’s no wonder broadcasters agree that Telos Systems makes the industry’s most powerful, intuitive and flexible system controllers, known as Telos VSets.
A multi-line phone system that connects to your console with just one cable? Meet iQ6, the no-hassle Telco gateway for Axia Audio mixing consoles. iQ6 plugs right into Livewire AoIP network networks, saving money and time.
Telos pioneered the very first digital adaptive telephone hybrid. These third-generation POTS hybrids have earned a worldwide reputation for extracting clean, clear caller audio from even the most difficult calls. POTS phones never sounded so good!
Audio Codecs & Transceivers
Z/IP ONE, the award-winning IP codec from Telos, helps you get the best possible quality from public IP networks and mobile data services; even from connections behind NATs and firewalls. It's the IP codec that drops jaws -- not audio.
Zephyr iPort PLUS Multi-Codec Gateway
Zephyr iPort PLUS is a Livewire-to-MPEG/AAC/aptX gateway that transports multiple channels of stereo audio across any QoS-enabled IP network -- perfect for large-scale distribution of audio to single or multiple locations.
Zephyr pioneered the concept of the ISDN codec -- which is why you'll find more Zephyrs in studios and remote kits around the world than any other codec.
Streaming Audio Processing + Encoding
The Future is Streaming. The Future is Here. High-quality adaptive streaming encoding.
Includes all of the revolutionary features found in Z/IPStream X/2, and exclusive Omnia.9 tools from Leif Claesson.
