TSL Provides Safety Net for Shanghai Media Group

Multichannel Touchmix Systems Match Main Console Channel Count

TSL Professional Products Ltd. (PPL), a manufacturer of hardware and software audio monitoring, tally and power management solutions for the broadcast industry, is pleased to announce the delivery of five Touchmix Combo Systems to Shanghai Media Group (SMG). SMG operates 14 television channels and 11 radio stations serving the Shanghai megalopolis, bringing diverse programming, sports and news to an audience of 1.6 billion. The dual Touchmix Combo systems will be installed in five television production studios as backup solutions for each studio’s main audio consoles, taking the capabilities of the Touchmix to the next level.

“The solution that SMG were looking for  represented a significant engineering challenge for us, but one that enabled us to deliver very positive results,” explains Martin Dyster, head of audio for TSL Professional Products Ltd. “SMG wanted to combine the standard rack-mount Touchmix unit and the desktop Touchmix Pilot remote into a system where, in the event that they lost the main audio console, its sound operator could keep the show live via the simple Pilot system with the tech manager providing configuration support via the rackmount unit if required. Our R&D team paired the units in a master/slave configuration and wrote new code to satisfy SMG’s requirement, resulting in an entirely viable solution that is relevant to many other applications/environments. In time honored fashion mimicking the evolution of many TSL audio monitoring products, the Touchmix Combo was born from a customer’s vision.”

SMG will use the Touchmix combo systems as a safety net for its 24-hour news operations. Each of its production studios is outfitted with a high-end digital audio console, with an associated audio engineer. The rack-mount Touchmix’s are located in the production room, where the technical manager can make configuration changes, freeing the audio engineer to use the desktop Touchmix Pilot to send the audio to air in the event of a main console crash. In the event that the primary audio console fails for some reason, the parallel configured Touchmix combo systems can take over the audio tasks for the program in production within seconds.


“While the Touchmix system always had mixing capabilities, the master/slave T-Mix/T-Mix Pilot combination is certainly unique”, concludes Dyster.

With the Touchmix Combo’s ability to adjust individual channel mix levels, control balance and pan whilst providing dual operator individual monitoring and dedicated program outputs, the new system is a truly capable audio mixing solution.

The main ‘host’ Touchmix unit (AVM-T-MIX) comprises two 20-channel audio mixers, each configurable as a combination of assignable stereo, mono or even surround input channels per mixer. The 22:9 aspect ratio touchscreen front panel provides volume control, a dual-function gain/balance encoder, headphone socket, USB port, home preset save/recall switch and loudspeakers. The Touchmix Pilot (AVM-T-MIX Pilot) comprises a desktop remote touchscreen panel with a rack-mount host unit. The two-unit combination packages for SMG are interconnected via Ethernet.
