Summary
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.
