What is the Frequency Shifter?


How the frequency shifter for TeamConnect Ceiling 2 with TruVoicelift enables optimal feedback suppression in meetings

As soon as the TruVoicelift mode is activated for TeamConnect Ceiling 2 in the Sennheiser Control Cockpit, the internal frequency shifter is also automatically active. An algorithm constantly adjusts the audio signal for optimal feedback suppression by changing the frequency. This reduces the likelihood of feedback occurring and achieves higher gain before feedback. ​ The frequency change is only a few hertz, which is not audible in standard speech applications.
