Tieline i-Mix G3 is the worlds most advanced IP codec for radio and Television, combining six essential live remote broadcast products into one lightweight 16" x 9" box, replacing tens of thousands of dollars of expensive equipment.

Broadcasting with the i-Mix is like having an entire remote truck in a single box. Designed by radio and television sports broadcasting specialists, it is ideal for sports broadcasts, talk shows, music and other live events. It is a multi-faceted unit that can be used as a mixer, a commentary control unit and a codec. It integrates bi-directional audio and full-duplex communications with extensive remote control capabilities to reduce setup time, on-site personnel, wiring requirements and signal distribution costs.

Modular and Flexible

Tieline i-Mix IP codecs feature a LAN connection, one built-in POTS codec and an analog telephone coupler. You can increase your programming, mixing and communications options by using the codec module slot to send high quality, low-delay live audio over 3G/3.5G, a second POTS/PSTN analog phone line, ISDN, X.21, GSM or B-GAN satellite networks.

In comparison with the field unit Commander G3, the i-Mix has additional balanced inputs, an onboard PA control, dedicated Cue/Comms buttons for communications and a telephone coupler for managing live talkback callers.

Why You Should Choose Tieline i-Mix Codecs...

Broadcasters over time will need to migrate to IP technology alternatives for remote broadcasts, audio distribution and STLs, as older synchronous networks such as ISDN are phased out.

Tieline G3 IP codecs are engineered to deliver rock solid and reliable audio over IP and wireless 3G/3.5G IP networks and they are also capable of connecting over POTS/PSTN, ISDN, X.21 and satellite networks. Therefore, with a Tieline G3 codec it is possible to take advantage of both new and old transports as telcos continue to transition into new IP-based technologies.

Many Tieline customers are already using G3 audio codecs over IP and 3GIP for broadcasting, audio contribution and STLs. IP can be used as the primary circuit for sending audio and you can use POTS or ISDN as a backup failover circuit or communications circuit. In this way your i-Mix IP codecs can truly grow with your needs and protect your investment as technology evolves.

The i-Mix G3 is also EBU N/ACIP Tech 3326 compatible over IP and the company is committed to developing new IP and 3GIP applications that take advantage of emerging network infrastructures around the globe.

Never before have so many powerful remote broadcast elements come together in one compact box. Contact Tieline now for a free demo and see what everyone else is talking about.

Onboard POTS/PSTN and your choice of IP, 3G/3.5G, POTS/PSTN, ISDN, GSM, X.21 and B-GAN satellite using a plug-in module.
A suite of algorithms to suit all your live broadcasting requirements including Tieline's famous Music, MusicPLUS and Voice G3* algorithms - as well as industry standards such as G.711, G.722 and MPEG Layer II.
Tieline's loss-tolerant MusicPLUS algorithm provides up to 20 kHz stereo audio quality with 20ms coding delay at bit rates as low as 96kbps - making it ideal for today's IP and 3G networks.
Tieline Music can deliver up to 15 kHz FM quality mono audio at bit-rates as low as 24kbps, with only 20 milliseconds encoding delay.
Tieline Voice G3* is optimized to deliver up to 7.5 kHz quality audio at bit-rates as low as 9.6 kbps.
A configurable 16 x 11 cross-point Digital Matrix Audio Router (DMR) for customizing your cue, intercom, talkback and audio routing and send any audio input to any audio output.
Comprehensive and configurable communications facility for local and full-duplex studio-to-remote communications.
Pre-configured and adjustable mono, stereo, mono/IFB and dual mono connection profiles.
A telephone coupler for taking live callers in the field.
On-board relay and RS-232 control system for local and remote control of equipment at either end of your codec link
Full control of a remote announcer's audio input levels from the studio.
Free Tieline Toolbox PC software configuration and control software, offering configuration, audio routing and input control of your local and remote codec.
Automatic connection failover.
* From the 31st March 2011 Tieline has discontinued support for the Voice G3 algorithm. As a result it has been omitted from the v.1.6.72 firmware release and all codecs purchased after this date. Codecs with firmware v.1.6.72 or higher can connect to G3 codecs running older firmware versions, but will have to use an algorithm other than Voice G3. Voice G3 is usually used for low-bitrate connections over GSM and POTS. We recommend using Tieline Music as a substitute for these low bit-rate connections.
