Activating/deactivating the low-cut filter
The low-cut filter reduces or removes low frequencies in the audio signal while allowing high frequencies to pass through. This allows low-frequency ambient noise to be filtered out of the audio signal, thereby improving the clarity of the recording.

Activating/deactivating the low-cut filter

The low-cut filter reduces or removes low frequencies in the audio signal while allowing high frequencies to pass through. This allows low-frequency ambient noise to be filtered out of the audio signal, thereby improving the clarity of the recording.

The low-cut function of the EW-DP SKP comes activated on delivery and can only be accessed via the Sennheiser Smart Assist app, which is available for both Android and iPhone (see Smart Assist app). The EW-DP SKP remembers the settings you make in the Smart Assist app and retains them even after it is switched off/on.

To activate/deactivate the low-cut filter:

Pair your EW-DP SKP with the app.
You can find the low-cut function under the “Audio Link Controls” menu.
Select the frequency at which you want the filter to start, or activate/deactivate it.
The low-cut filter is now activated/deactivated.
