 Tieline Commander G3 Rack Codec Figure 1Tieline Commander G3 IP codecs are amongst the world's most successful and widely used codecs for remote broadcasts, studio-to-transmitter links and audio contribution. The new TLR300B Commander G3 is a 2RU studio codec with comprehensive front panel hardware controls.

All Commander G3 codecs are 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.

Tieline Commander rackmount studio codecs offer a choice between analog or AES/EBU input/output modules (specify your choice when ordering). Add analog or AES/EBU I/O modules as your needs change (sold separately).

The Commander G3 studio codec comes in two sizes: 2RU with front-panel hardware control (this model here, the COMMBASESTUDIOIP) and 1RU with front panel status LEDs (COMMBASESTUDIOLITEIP). Both include wired IP Audio on board and accept all optional modules.

The 2RU COMMBASESTUDIOIP features comprehensive front-panel hardware control including 4 x LED/PPM meters which can be configured to show send/return or user selectable channel mix. It can also be remotely controlled via the Tieline PC GUI.
