Voice Lift in General TruVoicelift TeamConnect Ceiling 2 The voice lift feature was introduced to evenly most distant presenter can be understood. To achieve a sufficient gain before feedback (GBF), the microphones must be worn very close to the body. And the front-of-stage loudspeakers have to - Sennheiser TeamConnect Ceiling 2 | TeamConnect Ceiling 2 - TruVoicelift. Sennhei - Page 5
TruVoicelift TeamConnect Ceiling 2 Technical Challenges Despite key advantages over a PA/SR system, there are technical factors to consider when designing a typical voice lift application (see „Checklist for Voice - Sennheiser TeamConnect Ceiling 2 | TeamConnect Ceiling 2 - TruVoicelift.

Example 1 - Classroom When the system is integrated in a classroom, multiple TeamConnect Ceiling 2 units are used simultaneously and divided into coverage zones. The first coverage zone includes the teacher's area. A generous Priority Zone is set up for this area, based on how the teacher typically - Sennheiser TeamConnect Ceiling 2 | TeamConnect Ceiling 2 - TruVoicelift. Sennhei - Page 16
Easy Setup and Maintenance The microphone's central position on the ceiling eliminates the need for individual microphones on the table. For system engineers, integrating the system into an existing network does not require any complex analyses or installation work.
