Tieline ViA Duo, Portable Field Codec For Reporting, Commentary & Off-Tube Remotes (coming soon)

Tieline ViA Duo, Portable Field Codec For Reporting, Commentary & Off-Tube Remotes (coming soon)

ViA Duo is the new generation of trusted ViA technology that truly bridges the gap between field reporting and commentary. Built for reporters and commentators alike, it is an ultra-portable broadcast platform that can operate as an IP codec, AoIP commentary node, or facilitate off-tube broadcasting through support for audio and video feeds. Simply take the codec to the remote site, power it up, and connect to your preferred network and start broadcasting. 
There’s no need for additional outboard gear like mixers, equalizers, compressors, noise gates, expanders, recorders and playback machines – with ViA Duo it is all-in-one and ready to go! ViA Duo supports HDMI video out, multiple AoIP protocols, plus IP streaming over multiple interfaces. It delivers an all-in-one solution consolidating your remote broadcast, commentary and off-tube broadcasting requirements into a single compact and lightweight box.

Live Remote Broadcasts: ViA Duo can operate as an ultra-portable remote IP codec for reporters, sports commentators and radio announcers, as well as broadcasters working from home. The compact ViA Duo is lightweight and fits in the palm of your hand. It features 2 XLR mic/line inputs and headphone outputs and can send bidirectional stereo or dual mono audio from any remote location to the studio using cellular, Wi-Fi or Ethernet connections.

Customized Communications: With dedicated cue and talkback buttons, the codec integrates seamlessly with communications systems to facilitate mix-minus IFBs and full duplex communications over IP or AoIP networks. Customize cue and talkback matrices with the touch screen to route audio locally to headphones or outputs, or to the studio.

Rock Solid Redundancy Options: ViA Duo delivers reliability with multiple layers of redundancy that can be fully automated to ensure rock solid connections. Auto backup is provided through Tieline’s proprietary SmartStream PLUS hitless packet switching, which sets the benchmark for redundant IP streaming over the public internet. Unlike some other manufacturers, hitless packet switching is included FREE!

ViA Duo for Stadium TV Commentary: The ViA Duo can be used in a variety of broadcast commentary roles for radio and TV broadcasts. Optional support for AoIP protocols like RAVENNA, Dante, AES67, ST2110-30, Livewire and NMOS facilitates using ViA Duo as an AoIP node in stadium commentary booths or on the sideline. Flexible options include connecting over a LAN to a remote truck at a venue, or over a WAN with a REMI (Remote Integration) use case back to a mixing console at a studio hub.
