G3 New Cross Point Digital Matrix Routing (DMR) optional software

What does this mean, why is it so powerful and how does it replace racks of routing and communications equipment for a fraction of the price?

Built into every Commander and i-Mix G3 codec is Tieline’s new Cross point Digital Matrix Router software enabling routing of any audio input to any audio output.

In your studio or remote environment there are a number of audio feeds required to hang a broadcast together including program audio sends, off-air communications between the remote site and studio, remote and local audio headphone monitoring, PA sends, auxiliary sends to recording devices, studio to remote mix minus feeds and live telephone callers for talkback.

There are also a number of codec streams available over ISDN, POTS and GSM.

The above image is an example of the optional i-Mix G3 16x8 Cross point DMR. It allows you set up your codec audio paths to create simultaneous program and off-air communications feeds between the studio and remote codecs plus route the audio to selected headphones, codec encoders and decoders, PA and auxiliary outputs and even program level meters giving you complete control of your broadcast. Changes to the Digital Matrix Router can be made using the “Matrix” tab in the Tieline Toolbox.

In the above example mono program is being sent down Encoder 1 (which could be a single ISDN B channel or a POTS channel). All announcers can hear the audio in their left and right headphones until the Cue-Comms button on the i-Mix front panel is pressed by announcer one. This takes Announcer 1 off the main program channel and routes the audio to the right hand headphone of all commentators. It also reroutes the audio to encoder two which is an off-air communications channel back to the studio.

Program audio is showing on Peak Program Meter 1 (PPM1) and communications audio is routed to PPM 2. Local audio is routed to PA channel 1 output and audio from the studio is routed back over Decoder 1 to all headphones so that announcers can listen to the studio audio feed or instructions. Any combination can be selected.

Combining Tieline’s Cross Point DMR with the built in digital mixer and codec functions creates a powerful studio environment in the field. All you need is a Tieline codec with the Digital Matrix Router enabled in the codec.

Tieline’s Cross point DMR Unlock Key is a low cost purchase option with your Tieline codecs. The DMR is embedded in the Tieline code software and requires an unlock key to activate. You can experiment with Matrix configurations using the Tieline Toolbox Software client for free, but no changes can be downloaded to the codec until the unlock key for each codec is activated.

15kHz stereo over wireless networks - A Tieline World First

1st November, 2004, Tieline Technology (Perth, Australia), Maple Audio Technology (Shizuoka, Japan), K-MIX Shizuoka FM Broadcasting Co., Ltd (Hamamatsu, Japan) and Heavymoon, a dealer of Tieline Technology, (Tokyo, Japan) are pleased to announce the world's first audio codec technology capable of delivering bi-directional 15 kHz stereo audio over PHS and 3G wireless telecommunications networks in Japan.

For the first time, radio broadcasters can deliver broadcast quality stereo audio over wireless networks using the standard 3G cell phone service by NTT DoCoMo named FOMA (tm) or by dialing from a standard PHS 64kbps data channel at the remote broadcast site back to a standard ISDN line at the studio.

The 3G and PHS wireless solution has been integrated into Tieline's new G3 range of Commander and i-Mix digital audio codecs which are also capable of delivering 15kHz stereo over analogue telephone lines and up to 20kHz stereo over ISDN links. http://www.tieline.com
