How to Manually Switch the Sampling Rate on MoerLab Auracast Transmitters

How to Manually Switch the Sampling Rate on MoerLab Auracast Transmitters

NEW FIRMWARE FEATURE

Manual Sampling Rate Setting

SoundLinker™, TV hearMore™, and MoerDuo™ now support manual sampling-rate switching through their onboard controls. Select 24 kHz or 48 kHz directly on the device without connecting the transmitter to a PC.

Choose the right sampling rate for your application

Use 48 kHz for general audio applications where full-range sound quality is preferred. Select 24 kHz when connecting to compatible hearing aids or when optimized hearing-aid performance is required.
