Tieline Commander G3 Rack Audio Codec

g3rack

Summary

The 2RU Commander features two balanced XLR inputs with both front and rear panel headphone outputs and mic inputs. It also has four front panel PPM meters that can display send, return or selected channel audio levels. The screen features real time link information and all controls are available at a touch of a button, or they can be locked out.

The low-cost 1RU Commander is the perfect set and forget IP STL or audio distribution.codec. It includes all the functionality of the 2RU Commander with front panel status LEDs for power, audio, Telco interface status and framing. It can also be programmed and controlled using a PC-controlled GUI that emulates the front panel operations of the 2RU version

Free PC Control Software

2 FREE software packages are supplied with each Tieline Commander G3 rack-mount codec. The Tieline ToolBox PC software package provides the ability to configure your codec to suit each broadcast.

The TLG3 GUI software controller emulates the hardware front panel of the 2 RU Commander G3. It can be used to control 1RU or 2RU codecs using USB or RS-232 serial connections, or either local area networks or the Internet. This advanced software GUI can control all normal codec functions such as dialing, menu navigation, audio monitoring and level controls..

Digital AES/EBU Inputs = Unsurpassed Audio Quality

Commander G3 IP codecs offer a choice between analog or digital input modules – so now you can capture crystal clear digital audio and keep it in the digital domain using Tieline’s AES/EBU input/output modules.

You can choose either an analog two input/output card with XLR connectors or an AES/EBU two input/output card 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.

When purchasing any TLR300B codec you can choose any single input/output card and it will be included in the price of the codec (i.e. there will be no additional cost to the rack-mount price for the first card you choose).

  1. Analogue 2 in 2 out interface (Part No: TLANA2IN2OUT)
    Analog input card for Rack Mount Codec- Analog Commander Rack Mount codec input card. Featuring 2 input and 2 output on XLR connectors plus balanced Aux in/out on 6.35mm (1/4″) jack. Balanced Aux out may also be used as a headphone out.
  2. AES EBU 3ID interface (Part No: TLAESEBU3ID)
    Digital Input Card for Rack Mount Codec:- AES/EBU Digital Card with 2 in and 2 out balanced AES3 on (XLR) plus unbalanced (BNC) AES3 (jumper selectable) with unbalanced word clock input as AES3 output sync reference.
  3. AES EBU STR (Part No: TLAESEBUSTR)

Digital Input Card for Rack mount codec- AES/EBU Digital card with 2 in and 2 out balanced AES3 on XLR connectors plus AES balanced silence tone reference input as AES3 output sync reference.

Redundancy through Automatic failover

This powerful software option provides automatic switching from one network to another in the event of a link failure. For example, if your IP link fails it can automatically switch to a backup POTS, ISDN or 3G link. This provides great peace of mind for studio-to-transmitter links and live remote broadcasts in particular.
Flexible Connections and Control

All Commander IP codecs feature 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 controls. 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. RS-232 or raw control data can also be sent via the codec 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 remote codec audio inputs from the studio, so your 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.
