Wireless RF Transceiver Module
The subwoofer relies on a proprietary wireless link to synchronize audio frames with the main soundbar. A failure in the RF transceiver module—often caused by thermal degradation of the crystal oscillator or firmware corruption within the module's flash memory—results in a loss of synchronization (sync-slip). When the timing packets exceed a specific latency threshold, the subwoofer's internal logic initiates a mute command to prevent asynchronous noise, resulting in the 'cut out' perceived by the user.
