Rackmount features:

The new TLR300B Commander G3 studio codec comes in two sizes. A 1RU with front panel status LEDs and a 2RU with front panel hardware control.

The 1RU codec can be controlled by the Tieline Toolbox or the Codec Controller software connected via local LAN, WAN, USB or serial connector on the rear of the codec. It can even be remotely controlled over your Tieline link or the internet. The 1RU front panel status LED's include power, audio present and telco interface status.

The 2RU features comprehensive front panel hardware control including 4 x front panel 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.

Interface cards

The new commander now offers a choice between analog or input/output modules AES/EBU on the rear of the chassis.

Choose from an analog two input/output card with XLR connectors or AES/EBU two input/output cards on XLR connectors. AES/EBU clock choices include internal clock, external AES/EBU clock and external word clock. Tieline has also implemented an automatic failover from the selected external clock to the internal clock in the event of an external clock failure.

PC control

2 FREE software packages are supplied with the Tieline Commander G3 rackmount codec.

The TLG3 GUI Codec Controller software emulates the hardware front panel of the Commander G3 2RU and can be used to control codecs on local area networks or on the open internet.

The Tieline ToolBox PC software package offers complete configuration and audio routing enabling you to tailer your codec to suit each broadcast.

Automatic failover

This powerful optional software provides automatic switching from one network to another network in the event of a link failure. For example, if your IP link fails it can auto switch to a backup POTS link. Relevant modules must be installed.

5 Connection Profiles:

1. Mono Delivers bi-directional broadcast quality mono audio over a single POTS, ISDN, X.21, GSM or IP link.
2. Stereo Commander G3 offers two channel stereo and joint stereo options over ISDN and X.21 using the MPEG L2 algorithm. Tieline Music algorithm also offers 15kHz stereo over a single 64kb channel or stereo over IP at bit rates between 64kb and 384kb. Tieline is the first to offer 15kHz phase locked stereo over two analog telephone lines. You can also achieve up to 24 bit, 20kHz uncompressed low delay audio over IP.
3. Mono/IFB Delivers a bi-directional mono channel for program plus a separate full bandwidth off-air communications channel. Instead of using expensive communications equipment or cell phones to communicate between local and remote sites, the Commander G3 rack mount front panel features a cue-comms button which can be configured (using the DMR) for your choice of one to one or one to many communications off-air feeds. The Commander G3 field codec has front panel comms buttons which are software assigned. At the touch of a button on-air talent, producers, directors and engineers can by-pass the program feed and split headphone feeds into comms and main program audio at either end of your codec link.
4. Dual Mono This profile offers two unique options.
   a) Send your Commander G3 program audio to two different studios over any 2 networks
   simultaneously including POTS, ISDN, X.21, GSM or IP. Each studio will receive the same audio from the Commander G3 or;
   b) Connect one studio codec to two field codecs and run two separate simultaneous remotes over any two networks. Now two remotes only requires three codecs instead of four.
5. Bonded Mono Bad phone lines at the remote site? Bond two analog telephone lines together and combine their low bit rate connections into one high bandwidth channel to deliver 15kHz high quality audio. You are no longer restricted by bad phone lines at the remote site. (Normally one good analog telephone line will achieve 15kHz audio).

Remote Control:

Commander G3 features serial, USB and LAN interfaces. Two GPIO relay control inputs and two outputs (expandable to 8 using the optional Tieline CAN8+8 relay box) offer a variety of internal audio matrix routing and external machine control. Front panel hotkeys can be programmed to trigger relay and routing state changes or external relay devices can be interfaced to trigger machine control at either end of your link. RS232 or raw control data can be interfaced via the serial port and delivered to the other end of your codec link for external machine control.

Commander G3 is still the only codec to enable control of the remote codec audio inputs from the studio ensuring announcers no longer have to worry about understanding correct audio input levels. You can control one remote audio input or gang all remote audio inputs to a single control in the studio.

A New modular concept

Commander G3 is the first codec to feature two expansion slots which accept your choice of hardware and software modules. Combinations of modules offer you 15kHz mono over POTS, dual mono over POTS, stereo over POTS, mono/stereo over ISDN, mono over GSM wireless to landline and mono/stereo audio over IP and 3G data networks.

Simply buy the low cost codec hardware or software module you need. You can make the codec as simple or as fully featured as required. Now that's flexible!

	IP: Plug into a LAN network port or directly into an ADSL router and deliver 15kHz mono and stereo audio over DSL, cable, LAN, WAN and wireless 802.11x broadband networks. Uncompressed (Linear) 20kHz stereo for STL's and studio to studio managed IP links is also available. Learn more about IP at www.tieline.com/ip
	3G: Wireless broadband cellular networks offer the next generation in flexible remote broadcasts. 3G covers a broad spectrum of technologies which are slightly different in major regions of the world including 3G, UMTS, and EVDO. For more information on how to create live “on-the-spot” cellular broadband wireless remote broadcasts over your wireless 3G network.
	POTS: Use a single POTS module for up to 15kHz mono audio over POTS. Combine two POTS modules and use two telephone lines to send your program to two destinations or use 1 channel for program and the other for off-air comms or data. Bond two POTS channels for phase locked stereo.
	GSM Wireless: Only Tieline offers up to 7.5kHz over standard GSM networks and up to 15kHz over HSCSD GSM networks. Combine the GSM module with the Tieline field power supply for a completely wireless solution. Great for reporters on the move.
