Description
Big performance in a small, silent, affordable package! For over a decade, Telos VX broadcast phone systems have been the industry standard for bringing phone calls into any broadcast facility. VX Duo brings the same audio performance and user experience you'll find in the flagship VX Enterprise system to a compact, completely silent platform. This makes VX Duo an ideal choice for home and project studios and stations where all equipment is located inside a control room. The affordability of VX Duo puts the legendary performance of Telos VX within reach of any budget.
Features:
- Delivers the same user experience and audio performance of Telos Alliance's flagship phone system
- Comes with 2 channels/hybrids standard
- Expandable to a total of 8 channels/hybrids via additional 2 channel expansion licenses
- Includes smart AGC and the famous three-band adaptive digital dynamic EQ, a three-band adaptive spectral processor, and noise gating
- Includes wideband acoustic echo cancellation to eliminate feedback and allow natural conversations with callers when monitoring on open speakers
- Compact, fanless, and completely silent, allowing for in-studio installation
- Up to 3 units can be positioned side by side in a single rack space
- Works with all Telos VSet call controllers and VX-compatible call screening software
Duo is an expandable two hybrid/channel VX system
VX Duo comes with two hybrids/channels which can either be used for a single studio (two separate caller faders on the board) or split between two studios, such as an AM/FM combo, or a control room and production studio.
Need more channels? No problem! VX Duo is expandable in increments of 2 channels, making a 4, 6, or 8-channel system a simple matter of adding licenses as needed.
AES67 Support
VX Duo includes support for Livewire+ AES67, giving broadcasters the flexibility to integrate it into any Livewire or AES67 facility.
Pathfinder control and support
Build HTML5 control panels for VX Duo using our Axia Pathfinder Core Pro Broadcast Controller.
Pure digital call-handling throughout
Unlike other VoIP systems, there are no analog stages in VX Duo, ensuring you always get the highest possible call audio quality.
With a capacity for up to 8 channels (hybrids/faders), Telos VX Duo is an appliance-based system that is ideal for small- to medium-sized facilities.
- Base system is licensed for 2 channels, and can be expanded up to 8 channels total by adding additional 2 channel licenses
- Supports an unlimited number of SIP extensions
- Maximum simultaneous on-air calls: 96
- Maximum on-air calls that can be conferenced on one fader: 12
VX System Components
VX Duo is a small form factor appliance with two gigabit Ethernet ports. It is completely silent, making it ideal for deployment inside studios.
You'll notice there are no audio I/O or telco ports on VX Duo itself. That's because all I/O is interfaced via Ethernet. The AoIP network supports a wide variety of Axia audio consoles, AES67 audio devices, Telos VSet phones, console-integrated call controllers, and more. VoIP services connect through a dedicated WAN interface, which can also accept connections from VSet phones, console call controllers, and more.
