Codecs and Profiles

There are 5 software profiles offering unprecedented flexibility over POTS ISDN and GSM links.
  • Mono mode - delivers bi-directional high bandwidth 15-20kHz mono audio over a single, ISDN B Channel or up to 15kHz over POTS and GSM links
  • Stereo mode - delivers separate right and left channels over a single ISDN B channel or 2xB channels. Tieline is the first to offer 15kHz phase locked stereo over 2 x analog telephone lines.
  • Mono/IFB - (over POTS and ISDN) delivers a bi-directional mono channel for program audio plus a separate full bandwidth, bi-directional off-air communications channel. At the touch of a button you commentators can bypass the program audio feed and talk with anyone at the local or remote end of the codec link. You can even use the additional telephone coupler for a second communications link without interrupting your broadcast.
  • Dual Mono - Send your program to two separate locations from one codec over 2 x POTS channels or 2 x ISDN channels.
  • Bonded Mono - Bad phone lines in your area? Bond two telephone lines together and combine their low bit rate connections into one high bandwidth channel to deliver high quality audio. You are no longer restricted by bad phone lines in your area.

A new modular concept

i-Mix G3 comes with 1 x POTS codec on board plus an analogue telephone coupler. You can add additional POTS, ISDN and GSM codec cards into the expansion slot on the right hand side of the i-Mix G3 to increase your programming, mixing and communications options at a fraction of the price of regular codecs.

ISDN - Plug in the optional 2 x B channel ISDN card and select from G.711, G.722, Mpeg Layer 2 and Tieline’s own Music algorithm. Tieline is compatible with most major ISDN codec brands and is the first to offer 15kHz stereo over a single ISDN B channel using Tieline’s famous MUSIC algorithm.

POTS: Thanks to our unique modem stability software and algorithm technology Tieline has convinced even the most skeptical engineers that delivering 15kHz audio with rock solid stability over analogue telephone lines is simple and reliable. Now i-Mix G3 delivers 15kHz mono, stereo, dual mono and bonded mono connections over POTS links offering ground breaking flexibility to broadcasters. No matter how bad your telephone lines are, you will always get a high quality audio link.

GSM: Plug in the optional GSM module and deliver 7kHz audio over standard GSM networks and up to 15kHz over High Speed Circuit Switched (HSCSD) GSM networks. Simply dial between the GSM enabled codec to a POTS landline enabled Tieline codec. Use the battery module or vehicle power supply for a complete wireless solution.


16x11 Cross Point Digital Matrix Router (DMR) Software option:

Embedded in the Tieline i-Mix G3 software is an audio router allowing any audio, codec, headphone, telephone coupler and communications input to be routed to any local codec or remote codec output. This powerful software option can be used to customize your preferred configuration for local and remote off-air communications, program mixing, split headphone monitoring PA output and even PPM meter assignment to specific audio feeds. By purchasing the DMR unlock key you can replace thousands of dollars worth of extra patch panel, audio routing and communications equipment.


The power of live off-air communications

Instead of using expensive communications equipment or cellphones to communicate between local and remote sites, the i-Mix G3 front panel features yellow buttons which can be configured (using the DMR) for your choice of one to one or one to many off-air communications feeds. 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 the link.


A 7 input 3 output configurable digital mixing facility

i-Mix’s digital audio mixing facility features 5 mic line switchable inputs offering your choice of line level (15dB) unbalanced (35dB) low mic gain (55dB) medium Mic gain (65dB) and high mic gain (72dB) plus two line level outputs, an additional auxiliary unbalanced (15dB) input and output, telephone coupler in/out and POTS, ISDN and GSM in/outs, Using the DMR, you can configure this digital mixer to mix and route any input to any output of the remote or local codec.


Taking live callers in the field

A telephone talkback system has been integrated including analogue telephone coupler, front panel telephone control “cue” and “live to air” buttons to manage live callers in the field. Mix minus audio routing ensures caller audio is separated from the announcer’s audio feed and unique “Audio Ducking” software reduces the caller’s audio by up to 30dB when they try to talk over the announcer. When you are not using the telephone talkback system you can use the telephone coupler as another analogue telephone off-air communications feed.



On-board relay and RS-232 control system (also featuring 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 POTS, ISDN or GSM link. RS232 or raw control data can be interfaced via the serial, LAN or USB ports on the i-Mix G3 and delivered to the other end of your codec link via POTS, ISDN or GSM for external machine control.

i-Mix G3 is still the only codec to enable control of the remote codec audio inputs from the studio ensuring you have control over your talent’s audio input levels. You can control one remote audio input or gang all remote audio inputs to a single control knob in the studio.



Tieline Toolbox PC configuration and control software

A comprehensive PC software package which offers complete configuration, audio routing and control of your local and remote codec is supplied free with every i-Mix G3 (and Commander G3 codec)

Tieline i-Mix G3 is backwards compatible with all original Tieline G1 codecs and can be combined with the new Commander G3 field or rackmount codec for a complete end to end broadcast solution.
