Telos VX is the first VoIP (Voice over IP) system for broadcast and is ideal for radio and TV applications, as well as some government applications. From remote IFBs to audience call-ins, it can run anywhere from one or two lines in a small studio to the on-air phones for your entire plant, giving you incredible operational power, adaptable workflows, and superior audio quality.For medium to large facilities, the Telos VX Enterprise hardware appliance has an expandable capacity of up to 120 channels and can grow with your station over time.Main Features:Includes support for AES67, giving broadcasters added flexibility of integrating VX into any AES67 network and compatible SMPTE 2110-30 networks, in addition to Livewire networks.HTML-5 control via Pathfinder Core PRO.SIP call-handling throughoutno internal conversion to analog call handling like some other so-called VoIP systems.Works directly with hosted VoIP or PBX services, and in conjunction with a PBX may support POTS, T1/E1, and ISDN BRI for maximum flexibility and cost savings.*Standards-based SIP interface integrates with all modern VoIP-based PBX systems to allow transfers, line-sharing, caller ID, and common telco services for business and studio phones.Standard Ethernet backbone provides a common transport path for both studio audio and telecom needs, resulting in cost savings and simplified studio infrastructure. Connection to hundreds of control devices (software or hardware) is possible.Each call receives a dedicated processing path for unmatched clarity and superior conferencing.Native Livewire integration: One connection integrates caller audio, program-on-hold, mix-minus, and logic directly into Axia AoIP consoles and networks.Connect VX to any radio console or other broadcast equipment using available Telos Alliance AES/EBU, Mixed Signal, and GPIO xNodes. Audio interfaces feature 48 kHz sampling rate and studio-grade 24-bit A/D converters with 256x oversampling.Powerful dynamic line management enables instant reallocation of call-in lines to studios requiring increased capacity.VSet Call Controllers with full-color LCD displays and Telos Status Symbols present producers and talent with a rich graphical information display. Each VSet features its own address book and call log.The Drop-in VSet Call Controller modules can directly integrate VX phone control into your mixing consoles.Clear, clean caller audio from fifth-generation Telos Adaptive Telephony technology, including Digital Dynamic EQ, AGC, adjustable caller ducking, and audio dynamics processing by Omnia.Wideband acoustic echo cancellation eliminates open-speaker feedback.Support for the G.722 codec enables high-fidelity phone calls from iPhone and Android SIP softphones using a SIP server.XScreen call-screening software from Broadcast Bionics, provided at no cost.* Due to the wide variation in how traditional phone service can be delivered and the complexities involved in converting those services to SIP, we want to talk with you about your system design before you order. Telos has VX System engineers standing by to help you draw up a configuration that will ensure your VX purchase will perform to your expectations when using legacy telephony circuits.Specifications:Analog Inputs (with Telos Alliance xNode)Input Impedance: >40 k Ohms, balancedNominal Level Range: Selectable, +4 dBu or -10dBvInput Headroom: 20 dB above nominal inputAnalog Outputs (with Telos Alliance xNode)Output Source Impedance: <50 Ohms balancedOutput Load Impedance: 600 Ohms, minimumNominal Output Level: +4 dBuMaximum Output Level: +24 dBuDigital Audio Inputs and Outputs (with Telos Alliance xNode)Reference Level: +4 dBu (-20 dB FSD)Impedance: 110 Ohm, balanced (XLR)Signal Format: AES-3 (AES/EBU)AES-3 Input Compliance: 24-bit with selectable sample rate conversion, 32 kHz to 96kHz input sample rate capableAES-3 Output Compliance: 24-bit Digital Reference: Internal (network timebase) or external reference 48 kHz, +/- 2 ppm60 dB, 20 Hz to 20 kHzIP/Ethernet Connections(1) Gigabit Ethernet via RJ-45 LAN connection (AoIP)(1) Gigabit Ethernet via RJ-45 WAN connection (VoIP)FunctionsAll processing is performed at 32-bit floating-point resolutionSend AGC/limiterSend filterGated receive AGCReceive filterReceive dynamic EQDuckerSample rate converterAcoustic Echo CancellerPower Supply AC InputHot-swap capable dual-redundant internal auto-ranging power supplies. 90 132 / 187 264 VAC, 50Hz/60Hz.
