Summary
Overview
Tieline Commander G3 field and studio rack-mount IP codecs are used by thousands of broadcasters around the world every day for remote broadcasting, studio-to-transmitter links (STLs) and studio-to-studio audio distribution.
Recognized as the world’s most powerful and reliable codecs, the Commander G3 can connect over a variety of network transports. Featuring interchangeable module slots, they can be customized to connect over a variety of connections according to each broadcaster’s unique requirements.
All Commanders feature two module slots, which accept your choice of hardware plug-in modules. This allows broadcasters to send high quality, low-delay live audio over IP, 3G/3.5G, POTS/PSTN analog telephone lines, ISDN, X.21, GSM and B-GAN satellite networks.
