France’s M6 Group Hears Linear Acoustic

France’s M6 Group is using Linear Acoustic’s AERO.air (5.1) 10-channel TV audio processor and MetaMAX LA-5180 audio-metadata frame synchronizer for its terrestrial free TV and digital pay TV services.

Linear Acoustic says its AERO.air is equipped with ITU-compatible loudness controllers, upmixers, and metadata support, and it provides full-time, two-channel downmixing for legacy stereo paths. Upmixing is provided by the company’s UPMAX algorithm, which provides 5.1-channel audio with complete downmix compatibility. The audio processor also includes the new AutoMAX-II auto-detection algorithm to upmix or automatically bypass 5.1 mixed content.

On its MetaMAX LA-5180, the company adds that the frame synchronizer accepts professional audio metadata via a standard RS-485 serial input or as delivered inside the VANC space of an HD-SDI stream. The unit allows for on-the-fly correction of incoming errors, rewriting of all parameters, and reversion to fully adjustable, internally generated values output via serial and HD-SDI. It can also be used as a stand-alone generator with eight presets for both Dolby E and AC-3 metadata.
