Sennheiser’s TeamConnect Ceiling 2 ceiling microphone array for conferencing has received a free firmware update – TruVoicelift promises clear in-room audio for classrooms, lecture halls and boardrooms, with many user controllable features.

TeamConnect Ceiling 2For existing TeamConnect Ceiling 2 (TCC2) implementations, users can add TruVoicelift functionality by installing the free firmware update (1.6.4) via the new version of the Sennheiser Control Cockpit app (4.3.0).

New users gain two solutions in one – depending on the size and configuration of the room, additional TeamConnect Ceiling 2 microphones can be installed as audience mics, creating a completely touchless microphone solution that reduces potential hygiene risks.

TruVoicelift is powered by an advanced frequency shift algorithm that delivers extra gain – an enhancement that could make all the difference to perfectly hearing a lecturer or CEO. At the same time, TruVoicelift also includes a ‘feedback prevention mute’ function – if levels should get too loud, TCC 2 briefly mutes to prevent any feedback. During pauses in speaking, if a pre-defined audio threshold is not reached, a noise gate will be activated that mutes TeamConnect Ceiling 2 to prevent any background noise from being amplified.

All TruVoicelift settings can be controlled via the Sennheiser Control Cockpit app. The app also allows creation of ‘priority zones’ – areas where audio is predominantly picked up. This is helpful for any set-ups where audio usually comes from a defined place, such as the front of a lecture hall. Also, ‘advanced exclusion zones’ can be defined, enabling you to target and exclude noise sources with pinpoint accuracy, such as air conditioning or ventilation equipment.

‘The update expands the feature set of the conferencing microphone array to a completely new usage scenario for both corporations and education institutions,’ says Jens Werner, Portfolio Manager in Sennheiser’s Business Communication Division. ‘TruVoicelift helps to establish pleasant audio levels in a room, and lets speakers be confident that they can be perfectly understood throughout the entire auditorium.’
